Behavior Patterns among Children with a History of Metopic Synostosis
Metopic synostosis is a condition in which the metopic suture of the human cranium fuses prematurely and may be related to poor behavioral inhibition leading to behaviors commonly associated with Attention-Deficit Hyperactivity Disorder (ADHD). The purpose of this project was to examine the behavior patterns among children with a history of metopic synostosis. It was hypothesized that children with a history of metopic synostosis would exhibit many of the same behavioral patterns associated with ADHD. It was also hypothesized that children with a history of simple synostosis not involving the metopic suture would not evidence this type of behavioral pattern. In order to test these hypotheses, the behavior of three groups of children was compared including (1) children who had a history of metopic synostosis (M= 7.63 years, SD = 1.92 years), (2) children who had a history of simple craniosynostosis not involving the metopic suture (M= 7.54 years, SD = 1.88 years), and (3) a group of children diagnosed with ADHD (M=7.78 year, SD = 1.87 years). It was found using the Home and School versions of the Attention Deficit Disorders Evaluation Scale (ADDES) that children with a history of metopic synostosis demonstrate significantly more behavioral disturbances than children with a history of simple craniosynostosis not involving the metopic suture. Using the BASC Teacher Rating Form it was found that children with a history of metopic synostosis have a behavior pattern similar to children diagnosed with ADHD and a dissimilar behavior pattern compared to children who have a history of craniosynostosis not involving the metopic suture. Using the BASC Parent Rating Form it was found that children with a history of metopic synostosis have a behavior pattern dissimilar to children diagnosed with ADHD and a dissimilar behavior pattern compared to children who have a history of craniosynostosis not involving …
Bidirectional Effects Between Engaged Lifestyle and Cognition in Later Life: Exploring the Moderation Hypothesis for Personality Variables.
Longitudinal data (N = 263) was used to investigate the bidirectional relationship between engagement (engaged lifestyle activities) and cognition (crystallized & fluid intelligence). Extroversion and openness to experience were also tested as moderators of the relationship between engagement and cognition. Results showed that the relationship between engagement at Wave 1 and cognition at Wave 2 did not differ from the relationship between cognition at Wave 1 and engagement at Wave 2. Testing for moderation with regression indicated that neither extroversion nor openness was moderating the relationship between engagement and cognition in either direction. Structural equation models provided further summary evidence that the relationships among engagement at Wave 1, extroversion, openness, and cognition at Wave 2 were not strong. However, a strong limitation to these results was the measurement error associated with a new measure of engagement.
Boston Naming Test with Latencies (BNT-L)
Although most people have experienced word-finding difficulty at one time or another, there are no clinical instruments able to reliably distinguish normal age-related effects from pathology in word-finding impairment. Two experiments were conducted to establish a modified version of the Boston Naming Test (BNT) that includes latency times, the Boston Naming Test of Latencies (BNT-L), in order to improve the instrument's sensitivity to mild to moderate word-finding impairment. Experiment 1: Latency times on the 60-item BNT (Goodglass et al., 2001) for 235 healthy adults' ages 18-89 years were collected on a representative sample. Qualitative features of the BNT items, statistical analyses, IRT, and demographic considerations of age, gender, education, vocabulary, race and culture, helped create a reduced BNT-L version with 15 of the most discriminating items. Statistically sound and sophisticated normative tables are provided that adjust for unseen covariates. Response latencies did not indicate earlier age-related decline in an optimally healthy sample. Experiment 2: Twenty-three patients referred for neuropsychological testing were administered the BNT-L. Patients referred for evaluation of mild cognitive impairment or possible dementia produced significantly different response BNT-L latencies from the healthy sample whereas patients referred for mild brain injury evaluation did not. Normal word-finding problems were discussed in terms of serial stage models of lexical access, as well as in terms of automatic and controlled cognitive processes in younger and older adults. Statistical process for creating a psychometric instrument using latencies is illustrated.
Cardiovascular Problems as a Predictor of Later Cognitive Decline: Moderating Effect of General and Spousal Social Support.
Individuals are living longer now than they have in the past. As a result, there is an increased incidence in illnesses that are more prevalent in later life. One group of illnesses that is more prevalent is age related dementia. Alzheimer's disease (AD) and vascular dementia (VaD) are two common types of dementia found in the older adult population. Recent research suggests that these two types of dementia may both have a vascular component that is instrumental in their development. Not only may this vascular component be present in both these illnesses, but also it may be related to a more severe cognitive decline in the aging process. Results indicate that both cardiovascular disease and general and spousal social support in middle age are all three independent significant predictors of mild cognitive impairment and other non-normative cognitive impairment in later life. However, results do not indicate that social support moderates the relationship between cardiovascular disease and cognition.
Caregiving Style in Diverse Samples of Caregivers.
With three homogenous caregiver groups (i.e., Alzheimer's caregivers, grandparents raising grandchildren, parents), caregiving styles were explored to determine their reliability and validity, their unique role in predicting caregiver outcomes, and their differences between groups of caregivers. A conceptual framework was adapted to determine the impact of contextual variables, caregiving styles, caregiver appraisal, and mediating variables on caregiving outcomes. A more concise version of the Caregiving Style Scale (CSS) was developed with 49 items yielding an internal consistency coefficient of .74. As expected, three caregiving styles emerged and were positively related to the parallel parenting styles. Across the caregiver samples, there were positive relationships among caregiving style dimensions within the same caregiving style, while those from opposing caregiving styles tended to have negative relationships indicating good convergent and discriminant validity. Authoritative caregiving style dimensions were generally associated with healthier functioning, while authoritarian and permissive caregiving style dimensions were correlated with less healthy functioning. Caregiving style dimensions were among the predictors of several outcome measures, highlighting the importance of their placement in the conceptual framework for caregiver stress and coping. Generally, an unexpected finding was that authoritative caregiving style dimensions tended to predict less adaptive caregiving outcomes, particularly for parents and grandparents, while the impact upon caregiver well-being by authoritarian caregiving style dimensions varied throughout the caregiver groups. Results further indicated that different groups of caregivers tend to take on different caregiving styles, with grandparents and parents tending to differ significantly from Alzheimer's caregivers in their approaches to caregiving.
Change in Depression of Spousal Caregivers of Dementia Patients.
Caring for a family member or loved one with dementia places a heavy burden on those providing the care. Caregivers often develop chronic depression because of having to deal with this burden. A great deal of literature has been published discussing coping effectiveness, effects of social support, and other internal and external means of support for the caregiver. However, little has been written about the changes, if any, in depression that the caregiver experiences after the termination of care, either through institutionalization or death of the person with dementia. This study examined whether there is a change in depression of spousal caregivers after institutionalization of the dementia care recipient as well as any changes in depression that may have occurred as a result of the death of the dementia care recipient. Two theoretical models, the wear and tear model and the adaptation model were discussed in terms of caregiver depression after institutionalization of the dementia care recipient. Two other theoretical models, the relief model and the stress model, were discussed in terms of caregiver depression after the death of the dementia care recipient. Datasets from the National Institute on Aging sponsored Health and Retirement Study were analyzed. Results indicate that both male and female spousal caregivers report an increase in depression after the institutionalization or death of the dementia care recipient, but that as time passes, males report a decrease in depression while females continue to report an increase in depression.
Changes in Quantitative EEG and Low Resolution Tomography Following Cranial Electrotherapy Stimulation.
The effects of cranial electrotherapy stimulation (CES) on human EEG and brain current density were evaluated by quantitative electroencephalography (qEEG) and low resolution brain electromagnetic tomography (LORETA). A total of 72 research subjects were provided with a single session of CES, 38 were provided with 0.5 Hz CES while 34 were provided with 100 Hz CES. The qEEG paired t-tests revealed that in both frequencies of CES there was a significant (.05) increase in alpha relative power with concomitant decreases in delta and beta relative power. The 0.5 Hz CES decreased a wider frequency range of delta activity, while the 100 Hz CES decreased a wider frequency range of beta activity; suggesting some difference may exist in the EEG response to different frequencies of CES. The changes found in qEEG relative power were consistent with the affective and cognitive effects of CES reported in the literature, such as increased relaxation and decreased anxiety. Statistically significant changes for qEEG values other than relative power, such as coherence, amplitude asymmetry, phase lag and power ratios were also found. The LORETA paired t-tests found statistically significant (.05) increases in cortical and subcortical theta and alpha frequency current density with concomitant decreases in delta and beta current density. The effects of CES on current density varied by frequency, but did not show a differential in response based on proximity to the contacts, or structures within the brain. Statistically significant changes in current density were found in all 2394 gray matter voxels represented by LORETA, indicating a whole brain response to the CES stimulus. The qEEG and LORETA findings revealed that a single 20-minute session of CES does have a significant effect on the cortical and subcortical activity of the human brain resulting in activity consistent with decreased anxiety and increased relaxation.
Childhood Learning: Examining Attitudes toward School and Learning Ability
A child's ability to learn in school and school performance are affected by various factors. Variables that affect learning and academic performance in 46 children, 4 - 7 years old, were examined. Children, parents, and teachers completed questionnaires rating children's attitudes and behavior toward school. Children completed a computerized matching-to-sample (MTS) task. The MTS trained the children to form 3 stimulus classes. One stimulus class included three arbitrary stimuli, the others contained a positively or negatively valenced stimulus, a school-related stimulus, and an arbitrary stimulus. Class formation performance was assessed. Rate of learning predicted attitudes toward school, school attitudes predicted academic performance; however a hypothesized mediation effect of attitudes was not demonstrated. No significant differences in rate of forming stimulus classes containing emotionally valenced and school stimuli were found. Future directions for intervention in the early education of students who have poor attitudes toward school are discussed.
Client's Perception of Seeking Counseling as a Function of Counselor Ethnicity, Counselor Acculturation, Counselor Gender, and Client Gender
Due to demographic shifts and efforts to recruit culturally diverse professionals, it is plausible that more Caucasians will encounter ethnic minority counselors in the future. Yet, the majority of multicultural literature has only emphasized Caucasian counselors' multicultural counseling competence. Research has rarely discussed how ethic minority counselors influence the perceptions of Caucasian clients. The research purpose was to explore how acculturation and gender of Asian and Caucasian counselors influence Caucasians' perceptions of the counselors and counseling services. With an analog research design, 562 Caucasian college students read 1 of 8 randomly assigned counselor descriptions, which were varied by counselor characteristics, and reported their perceptions on dependent measures: Counselor Rating Form - Short Version (CRF-S), Working Alliance Inventory - Short (WAI-S) and 4 Willingness items. With the Attitudes Toward Seeking Professional Psychological Help - Shortened Form as a covariate, 15 hypotheses were expected that Caucasians would prefer high-acculturated, same sex, and same ethnic counselors tested by simple contrast, while an exploratory question, investigating main and interaction effects among independent variables (counselor ethnicity, acculturation and gender, and participant gender) on dependent measures, was examined by MANCOVA and ANCOVA. Although only 2 of 15 hypotheses showed significance, the exploratory investigation revealed: Caucasian participants had a preference of high-acculturated counselors on CRF-S attractiveness, WAI-S and willingness to seek help. However, present data did not replicate the impression of similar ethnic matching in counseling dyads. On CRF-S expertness, Caucasian participants reported that Asian male counselors were perceived as more expert than Caucasian male counselors. For gender differences, the current finding showed that female participants were more willing to seek help for academic/career concerns, whereas male participants were more willing to discuss their somatic concerns. For the research implications, with appropriate trainings in multicultural counseling competence, both Caucasian and non-Caucasian counselors could become effective therapists. Counseling …
Clustering of Behavioral Data for Identification of Presumptive Subtypes of Attention Deficit/Hyperactivity Disorder in Children
The objective of the present study was to investigate Amen's formulations of subtypes of AD/HD initially identified by brain imaging techniques, through the use of behavioral checklist data. And in testing Amen's theory of six separate subtypes of AD/HD, to identify and differentiate the subtypes based on symptom presentation. Data was obtained through retrospective chart reviews (N=161) of children between the ages of 5 and 12 who met the criteria for the major symptoms observed in AD/HD and were referred for a previous comprehensive AD/HD evaluation. Data from behavioral checklist (CBCL and DBRS-IV) were matched to Amen's Subtype Symptom Checklist and each subject was given a percentage score for six subtype symptoms. Cluster analysis reliably found six clusters and each subject was labeled according to their symptom presentation. The clusters found were labeled as AD/HD - Combined Type, AD/HD - Predominately Inattentive Type, AD/HD - Predominately Hyperactive-Impulsive Type, Ad/HD - Combined Type with Obsessive-Compulsive features, AD/HD - Combined Type with Obsessive/Compulsive and Conduct Disorder features and Undifferentiated AD/HD. However, the present study did not find evidence of subtypes that corresponded to Amen's Temporal Lobe ADD or Limbic ADD. Discriminant function analysis of the six clusters found that the variables in the model (symptom percentage scores) significantly discriminated the subtype classification. Also, 76% of all cases were correctly classified according to their symptom presentation. Potential limitations of the sample and the data used for interpretation were discussed. Limitations of the study warrant further investigation making use of multi-modal assessment tools which relate well with brain imaging techniques, such as neuropsychological measures of attention and concentration, laboratory based measures of activity, continuous performance tests measuring inattention and impulsivity, and QEEG data measuring brain wave information. A multi-modal approach to investigating symptom subtypes of AD/HD would likely provide increased reliability and validity of …
Cognitive and Perceptual-Motor Indicators of Lateralized vs. Diffuse Brain Damage in Adults.
Among the goals of the neuropsychological assessment are to detect the presence of brain damage, localize which areas of the brain may be dysfunctional and describe subsequent functional impairments. The sensitivity of neuropsychological instruments in carrying out these functions is a question of some debate. The purpose of this study is to determine the utility of lateralizing indicators from the WAIS-III, McCarron Assessment of Neuromuscular Development (MAND) and Haptic Visual Discrimination Test (HVDT), from the McCarron-Dial System Neuropsychological Assessment Battery (MDS), in ascertaining the presence or absence of brain damage as well as location of lesion. The classification accuracies of using performance level indicators from these tests and lateralizing indicators, alone and together, were compared.
Cognitive Complexity and Construct Extremity in Social and Life Event Construing in Persons with Varied Trauma History
The purpose of this study was to examine cognitive complexity, extremity, and the relationship between social repertory grids and life events repertory grids (LERG) in people who report a history of trauma. Effects of type of trauma on complexity and extremity scores of each type of grid were examined. Prior research into repertory grids and trauma has used only one type of grid, predominantly social grids or LERGs. Therefore, a natural, progressive step in the grid research involved investigating how individuals integrate social and life event constructs. It was hypothesized, and results show, that there is a positive correlation between complexity scores and extremity scores of social grids and LERGs. However it was not found that there was a negative correlation between trauma history and complexity scores, and that trauma acts as a moderator for cognitive complexity. Instead, it appears that the social facet of experience is key to understanding perception of traumatic experiences. Additionally, number of traumas experienced might affect social construct elaboration.
Cognitive Differences Between Congenitally and Adventitiously Blind Individuals.
It is apparent from the historical perspective regarding the theories of cognitive development and the cognitive functioning of individuals with visual impairments, that sight plays a major role in the development of certain cognitive processes. However, the affects of visual impairment on cognitive development remain to be at issue. Since sight seems to be highly integral in cognitive development beginning in the early stages of physical development, about the sixth month of life, and then begins to diminish in importance as verbal communication develops around eighteen months, then it should stand to reason that significant visual impairment or blindness occurring prior to this time would adversely impact an individual's cognitive development. Conversely, the occurrence of visual impairment or blindness after this critical period of development would have less of an impact. Cognitive theorists have proposed that visually impaired or blind persons may have developed different cognitive pathways to acquire, process, and accommodate sensory information. As a result, visually impaired or blind (VI/B) persons may "think differently" than sighted individuals. The present study was designed to address these issues as they relate to cognitive and neuropsychological development at various stages of growth and to examine possible differences in neuropsychological functioning dependent on the level of visual functioning a person retains; e.g. both the issues of age at onset and degree of impairment. It was also designed to study the possible interaction effects of degree of impairment with the age of onset. Findings indicated that the only differences in cognitive functioning appear to be related to age of onset and not the level of visual impairment. The findings further suggested that congenitally blind individuals have indeed developed alternate methods of cognitively processing nonverbal, abstract, or complex information, especially information involving a high degree of spatial orientation. Implications of this study may influence …
Cognitive Dysfunction in Middle-Aged Adults vs. Older Adults with Obstructive Sleep Apnea
The presence of cognitive deficits in obstructive sleep apnea (OSA) is well-documented. Specifically, short- and long-term memory, attention/vigilance, and executive function (e.g. processing speed, mental flexibility, and problem solving) are affected. Cognitive deficits in aging occur in similar areas (i.e., memory and processing speed). Given that a greater percentage of older adults experience sleep-disordered breathing as compared to middle-aged adults, it is possible that OSA may account for some of the deficits typically attributed to aging. This study investigated this hypothesis by comparing middle-aged and older adults with and without OSA on computer-based measures of cognitive performance. No effect of OSA or an interaction between OSA and age on cognitive function was found; an effect of age on processing speed, distinguishing stimuli rapidly, attention, spatial ability/mental flexibility, and both working memory and short-term visual memory was found. This study also explored whether or not cognitive function may be improved in persons with OSA by re-assessing those participants one month after treatment. An effect of treatment on improvements on processing speed, distinguishing stimuli rapidly, mental flexibility, and short term memory was found. Overall, findings reflect the ability of treatment to improve cognitive function among OSA patients, regardless of lack of deficits when compared to those without OSA.
Cohort Differences in Perceptions of Helpful Counselor Characteristics
The present study examined age cohort differences in older and younger adults as they relate to perceptions of helpful counselor characteristics. The present study also assessed whether previous help-seeking behavior influences perceptions of what counselor characteristics would be helpful. The social influence model is used as basis for predictions. The first research hypothesis for the present study was that there would be an age by cohort interaction in perceptions of helpful counselor characteristics at both Time 1 (1991) and Time 2 (2001). The second research hypothesis was that there would be a main effect for cohort, with more recently born cohorts preferring more interpersonal counselor characteristics. The third research hypothesis was that there would be a main effect for age in endorsement of the social influence model. The fourth research hypothesis was that there would be a significant difference between the perceptions of those individuals who had previously sought help from a mental health professional and those individuals who had not sought help, regardless of age and cohort. A revised Adjective Check List (Gough, 1965; Gough & Heilbrum, 1983) was used to assess perceptions of helpful counselor characteristics. Chi-square analyses, MANOVA/supplementary ANOVAs, and exploratory factor analyses were used to test the research hypotheses. The first and second research hypotheses were supported. The third research hypothesis was not supported. The fourth research hypothesis was supported for Time 1, but not for Time 2. Limitations of the present study and implications of this research are discussed.
Collaboration for Organization Success: Linking Organization Support of Collaboration and Organization Effectiveness.
What does it take for organizations to support people working together effectively? What does it mean for an organization to be effective? Does successful collaboration lead to more effective organizations? This study explored these questions both theoretically and empirically in an effort to help organizations understand the most important aspects to consider when attempting to achieve collaboration for organization success. The purpose of this study was to fill some of the gaps in the research by taking a broad, holistic approach to exploring the context required to support collaboration at levels of organizations broader than the team and exploring the links between organization support of collaboration and organization effectiveness. In preparation for the current study, the Organization Support of Collaboration model was developed to identify the broad organization design elements that are required to support collaboration. The Organization Effectiveness model was created to provide a holistic view of what it takes for an organization to be considered effective. The present study empirically validated these models and explored the links between them. Data was collected via a web-based questionnaire administered to a broad sample of individuals who work in organizations. Results supported a model of Organization Support of Collaboration with six factors (Connect to the Environment, Craft a Culture of Collaboration, Understand Work Processes, Design Using an Array of Structures, Build Shared Leadership, and Align Support Systems) and a model of Organization Effectiveness with six factors (Performance, Employee Involvement, Flexibility, Customer Satisfaction, New Customer Development, and Treatment of People). Connect to the Environment predicted five of the six Organization Effectiveness factors, and Craft a Culture of Collaboration predicted four of the six, notably with a connection to Performance. For the predicted relationships between the models, nine hypotheses were supported, six were not supported, and three unexpected significant relationships were found. Implications …
College Student Identity and Attitudes Toward Gays and Lesbians
This study investigates the relationship between an individual's attitude toward gay men and lesbians and their identity development. The sample included 440 undergraduates from a university in the northeast Texas area. Many, if not all, of the factors that are associated with negative attitudes toward gays and lesbians (i.e., restrictive gender-role attitudes, high levels of authoritarianism, perceptions of negative attitudes toward homosexuals within their peer group, little or no contact with homosexuals, and conservative religious ideologies) have a logical relation to identity development. Furthermore, the various functions that attitudes toward gays and lesbians can serve (e.g., value-expression, group membership) were hypothesized to be especially attractive for persons in specific identity statuses. Thus, the case was made that identity development may be a valuable framework in which to understand attitudes toward gays and lesbians. In the current study, attitudes toward gays and lesbians were related to identity development, though the relationship is complex. When comparing persons who were higher and lower on absolutism, attitude toward gays and lesbians were most similar in achieved identity groups, while those who were foreclosed were the most disparate. In the interaction between identity, absolutism and gender role stereotyping, some groups utilized their attitude to express values more than other groups. Clinical implications as well as limitations of the study are discussed.
Combat Posttraumatic Stress Disorder: Effect of Intelligence on Symptomatology
The objective of this study was to examine the relations between Posttraumatic Stress Disorder symptomatology and intelligence. Thirty American combat veterans of the Vietnam War, diagnosed with chronic PTSD, were given a psychodiagnostic structured interview. Participants were assessed for Intelligence Quotient as well as the veracity of their self report. The study found that there were significant differences in how participants experienced their PTSD symptoms that were correlated with intelligence. The higher IQ participants reported more frequent and intense guilt related symptoms as well as more intense intrusive recollections. The lower IQ participants experienced more frequent startle responses, more intense problems related to falling or remaining asleep and more frequent affective symptoms related to emotional numbing. Psychologists could use these differences in how PTSD is experienced in treatment planning. It may be useful for therapy to address sleep disturbances and affective numbing in lower IQ individuals. Therapy for higher IQ individuals may be more useful if it addresses feelings of guilt and intrusive recollections.
Comparative Analysis of Chronic Versus Acute Stressors and Their Influence on Distress Consequences at Work
Workplace stress has been found to be a causal agent of psychological distress consequences in employees. Chronic stressors have been well researched, in particular, role conflict, role ambiguity, and work overload have been extensively studied. A meta-analysis was conducted in order to aggregate past research to gain a better understanding of the impact these stressors have on the psychological distress consequences of depression, tension/anxiety, somatic complaints, and generalized feelings of stress. Only role ambiguity was found to be a significant contributor to psychological distress, in particular to feelings of depression and stress. In general, however, effect sizes for all three stressors were moderate to large. While chronic stressors have been well researched, acute stressors have been widely overlooked. Since research in this area is limited, the Daily Work Hassles Survey was developed and validated in order to analyze the role daily hassles play in the workplace. The survey yielded two factors, Interpersonal Hassles and Task Hassles. The former of which was found to be significantly related to the distress consequences of depression, tension/anxiety, somatic complaints, and general feelings of stress. The ultimate goal of this project was to compare chronic and acute stressors. Results from the daily hassles study were contrasted to the results of the aforementioned meta-analysis. It was found that the chronic stressors of role ambiguity, role conflict, and overload are significantly greater predictors of selected distress consequences than the acute factors of Interpersonal Hassles and Task Hassles. However, when somatic complaints was employed as the dependent variable, no significant differences were found between chronic and acute stressors.
Comparative Models of the Impact of Social Support on Psychological Distress in Cancer Patients
This study tested the relationship between Social Support, Psychological Distress, and Illness Stress in individuals who report cancer as a health condition. This study was based on archival data obtained from the Wave 1 of the Health and Retirement Study (HRS). The HRS provides a nationally representative sample of individuals aged 51 to 61 in 1992 and their spouses. The study sample was limited to cancer patients with a spouse or partner (n = 503). A structural equation modeling analysis procedure was used to test the theoretical models. Measures of social support were limited to variables assessing the participant's satisfaction with social support. Evidence was found for the Stress Prevention and the Support Deterioration models. This is congruent with previous research using measures of social support perception. Both the Stress Prevention and the Support Deterioration models predict a negative relationship between Illness Stress and Social Support. In addition, a univariate analysis of variance was used to test the stress buffering model. Similarly to other studies measuring the individual's degree of integration, or its perception, in the social network, the present research supported the only the Main Effect model and not the Stress Buffering model.
Comparing Five Empirical Biodata Scoring Methods for Personnel Selection
A biodata based personnel selection measure was created to improve the retention rate of Catalog Telemarketing Representatives at a major U.S. retail company. Five separate empirical biodata scoring methods were compared to examine their usefulness in predicting retention and reducing adverse impact. The Mean Standardized Criterion Method, the Option Criterion Correlation Method, Horizontal Percentage Method, Vertical Percentage Method, and Weighted Application Blank Method using England's (1971) Assigned Weights were employed. The study showed that when using generalizable biodata items, all methods, except the Weighted Application Blank Method, were similar in their ability to discriminate between low and high retention employees and produced similar low adverse impact effects. The Weighted Application Blank Method did not discriminate between the low and high retention employees.
A Comparison of Miranda Procedures: The Effects of Oral and Written Administrations on Miranda Comprehension
Millions of custodial suspects waive their rights each year without the benefit of legal counsel. The question posed to psychologists in disputed Miranda waivers is whether this waiver decision was, knowing, intelligent, and voluntary. Mental health professionals must be aware of potential barriers to Miranda comprehension to provide expert opinions regarding a defendant's competency to waive rights. The current study examined how Miranda warning reading level, length, and method of administration affects Miranda comprehension. Recently arrested detainees at Grayson County Jail were administered oral and written Miranda warnings from the Miranda Statements Scale (MSS; Rogers, 2005) to measure their comprehension of the warnings. Surprisingly low levels of Miranda comprehension were found for most warnings. For all warnings at or above 8th grade, a substantial minority (27.1% - 39.6%) of defendants exhibited failed (i.e., < 50% understanding) Miranda comprehension. Regardless of other variables, oral administrations resulted in a substantially larger number of defendants with failed Miranda comprehension. Implications for public policy and clinical practice are discussed.
Compassion and Person Perception: An Experiment
Compassion is one of the fundamental experiences which signify human existence. Person perception is the constructive process with which we form an opinion or judgment of another person. Two experiments (N =277) were conducted in this study. Experiment 1 examined the effects of a mindfulness meditation on compassion in a large sample of young adults. Participants (n =76) were randomly assigned to three groups. Participants in group 1 received the mindfulness meditation, group 2 received an alternate version of the mindfulness meditation (self-focus only), and participants in group 3 were asked to complete an attention task and read a geological text. It was hypothesized that mindfulness meditation is significantly associated with the experience of compassion. Results showed that participants in the experimental group 1 experienced significantly higher levels of compassion compared to participants in the control group 3. The participants in group 2 were not different from experimental group 1 or from control group 3. Gender differences in the effects of meditation on compassion were explored. Different measures yielded conflicting evidence for gender differences in experienced compassion. For the second experiment a Solomon four-group experimental design was employed to examine the possible effects of compassion on person perception. Participants (n = 201) were randomly assigned to 4 groups. The effect of pretesting impression formation on posttest performance was investigated. It was hypothesized that compassion has a significant effect on impression formation. The Stouffer's z -method was used to investigate this effect. Results indicated that participants in the experimental groups after completing a mindfulness meditation rated a target person significantly more favorable, compared to participants in the control groups. Results also indicated that pretest had no significant effect on post-test ratings of the impression formation task. Transcendental applications for the inducement and experience of compassion in psychotherapy and the role of …
Competency to Stand Trial: A Systematic Evaluation and Validation of the GCCT, MacCAT-CA, and ECST as Competency Measures
Competency to stand trial cases constitute the largest percentage of forensic referrals for clinical psychologists. Furthermore, research suggests that the use of forensic measures facilitates the decisions of competency made by forensic examiners. This study investigated the construct validity of three competency measures: (a) the GCCT-MSH, (b) the MacCAT-CA, and (c) the ECST with 100 adult males incarcerated at the Tarrant County Jail in Fort Worth, TX. Construct validity was investigated via the use of a multitrait-multimethod research design for the three-prong conceptualization of the Dusky standard. Results indicated that current competency measures do an adequate job of assessing for factual understanding, but lack construct validity for two prongs: rational understanding and the ability to consult with counsel. In addition, the atypical presentation scales of the both GCCT and the ECST performed well at screening individuals for feigning. Finally, prediction of competency from clinical variables was also investigated. Psychotic symptoms and overall impairment were the strongest predictors of incompetency.
A Confirmatory Factor Analysis of WRAML Scores in a Group of Academically Talented Students
The purpose of this study was to confirm the original factor structure of the Wide Range Assessment of Memory and Learning (WRAML) utilizing a non-clinical adolescent population. Additional analysis examined the relationship between SAT-M scores and spatial relations ability. Exploratory analyses were conducted to determine ethnic and gender differences on the WRAML and subtests from the DAT. Sixty-four academically talented adolescents completed the WRAML and the mechanical reasoning and spatial relations subtests from the Differential Aptitude Test (DAT). The confirmatory factor analysis found the data obtained to not be a good fit for the factor structure of the WRAML (Sheslow & Adams, 1990). Additional confirmatory analyses were conducted which examined data fit of a three factor model found by reanalyzing the standardization data (Burton et al., 1996; Wasserman & Cambias, 1991) as well as two null models. The data failed to fit any of these three models. No support was found for the second hypothesis that predicted a positive relationship between SAT-M scores and spatial relations ability. Ethnic and gender differences on the WRAML and two DAT subtests were examined and discussed. Limitations of this study were reviewed which may have accounted for the overall lack of results.
Construct Validity of Psychopathy in Mentally Disordered Offenders: A Multi-trait Multi-method Approach
Psychopathy continues to receive increased attention due to the negative outcomes, including recidivism, violence, and poor treatment amenability. Despite the vast amount of attention psychopathy has received, research on its applications to mentally disordered offenders remains sparse. The current study explored the relationship between psychopathy, depression, anxiety, and psychotic disorders. It also investigated the comparative fits of two and three-factor models of the PCL-R with mentally disordered offenders. Participants consisted of 96 inmates placed in the mental health pod at Tarrant County Jail. A Confirmatory Factor Analysis (CFA) with testlets found the three-factor PCL-R model had excellent fit (Robust Comparative Fit Index = 1.00). Psychopathy was found to be a construct independent of mental disorders. Two exceptions were (a) a modest correlation between anxiety and Impulsive and the Irresponsible Lifestyle factor of the PCL-R (r = 0.20) and (b) a modest negative correlation between Deficient Affective Experience of the PCL-R and mania (r = -.37). Based on the current data, treatment programs for mentally disordered offenders are suggested that focus on both behavioral and personality aspects of psychopathy.
Contextualized Risk Assessment in Clinical Practice: Utility of Actuarial, Clinical, and Structured Clinical Approaches to Predictions of Violence.
Assessing offenders' risk of future violent behavior continues to be an important yet controversial role of forensic psychologists. A key debate is the relative effectiveness of assessment methods. Specifically, actuarial methods (see Quinsey et al., 1998 for a review) have been compared and contrasted to clinical and structured clinical methods (see e.g. Hart, 1998; Webster et al., 1997). Proponents of each approach argue for its superiority, yet validity studies have made few formal comparisons. In advancing the available research, the present study examines systematically the type of forensic case (i.e., sexual violence versus nonsexual violence) and type of assessment method (i.e., actuarial, structured clinical, and unstructured clinical). As observed by Borum, Otto, and Golding (1993), forensic decision making can also be influenced by the presence of certain extraneous clinical data. To address these issues, psychologists and doctoral students attending the American Psychology Law Society conference were asked to make several ratings regarding the likelihood of future sexual and nonsexual violence based on data derived from actual defendants with known outcomes. Using a mixed factorial design, each of these assessment methods were investigated for its influence on decision-makers regarding likelihood of future violence and sexually violent predator commitments. Finally, the potentially biasing effects of victim impact statements on resultant decisions were also explored.
Correlates of a Past Behavior Interview for the Business Unit Leader: Experience, Motivation, Personality and Cognitive Ability
This research evaluates the relationship between various individual differences constructs and performance on a past behavior interview (PBI)-one of the most popular forms of personnel selection interviews used today-within a sample of business unit leader level incumbents and applicants from organizations across the United States. Correlation analysis is conducted on the relationship between overall performance on a PBI and four work-related constructs: Experience, Motivation, Personality, and Cognitive Ability. The existing literature on PBIs and the four independent variables is critically reviewed. As limited research has been conducted on the influence of Experience and Motivation on PBI performance, this study makes unique contributions to the literature regarding impact of these two constructs. The major hypotheses stated that Experience and Motivation would yield significant, positive correlations with PBI performance while Personality and Cognitive Ability would not be significantly correlated with PBIs. Results partially supported the hypotheses-Experience, Motivation, and Personality were significantly related to overall PBI score, while Cognitive Ability was not. Implications for the findings as well as suggestions for future research are discussed.
Creativity and Affective Traits Across the Life Span: Developmental Influences Among Adolescents and Older Adults
In recent years, empirical research has consistently supported an association between susceptibility to affective illness and creativity at the level of eminent achievement and at the non-eminent, or "everyday creativity" level. Although this research has provided greater evidence for the existence of this link, it has simultaneously unearthed more questions about how and why such an association exists. The purpose of this research was twofold: first, to provide further analysis of the nature of the relationship between hypomanic traits and creativity by employing a longitudinal study to determine the extent to which inter-individual differences over time in creativity are predicted by hypomanic traits. Second, the purpose of the cross-sectional analysis in the present study was to further determine how developmental components such as age and expertise may help unravel the ways in which hypomanic traits contribute to creativity and to further describe inter-individual differences among these variables. The first hypothesis, which proposed that the direction of the relationship between hypomanic traits and creativity could be predicted, was not supported by these results. The second research hypothesis was partially supported: hypomanic traits predict creativity in the combined adolescent and older adult samples. However, upon further examination of the regression analyses, the data indicate that the relationship between hypomanic traits and creativity is also influenced by age and developmental factors. Furthermore, the way in which the relationship is influenced by these other factors depends on the way in which the creativity construct is measured (e.g., process or personality. The findings suggest that the antecedents of creativity may differ between adolescents and older adults. In adolescents, the hypomanic traits measure is the only variable that predicts creative personality and creative process, while expertise is the only variable to predict creative personality and creative process among the older adults in this study. It appears …
A Cross-sectional and Longitudinal Study of Adolescents and Religion: Views of Risk and Resiliency
The research literature within the past decade has documented the importance of religiosity and spirituality in helping many adults around the world cope with major life stressors and events. Still, the role of religiosity and spirituality in adolescence is not well-known as research during this developmental period has been limited by sample size, homogeneity of samples, ethnic restrictions, and use of scales with few items. The goal of the current study is to identify and understand adolescent levels of religiousness and spirituality, as well as their roles on later social, emotional, and behavioral outcomes. The current study relied upon data from the National Longitudinal Study of Adolescent Health and utilized confirmatory factor analysis and structural equation modeling in order to generate models of the relationships between the various latent variables. The religiosity and spirituality factors in the current study adequately measure religious perceptions and practices of adolescents over time. These constructs also play a role in later emotional well-being and self-esteem. Analyses also found adequate predictive abilities in the other model factors of delinquency, psychological well-being, self-esteem, and the social support. It is concluded from this study that religiosity and spirituality are not interchangeable constructs, and that more robust measures of both factors yield richer results. It is recommended that more comprehensive scales of religiosity and spirituality be developed and investigated in the future.
The Cross-Validation of AD/HD Instruments and the Relationship to Neurocognitive and Behavioral Measures
The purpose of this study was twofold: to determine the construct validities of comparable AD/HD instruments that were developed according to our current, DSM-IV classification system for AD/HD; and to identify potential +neurocognitive and socioemotional markers for AD/HD. The sample consisted of 145 children ages 8 to 11 years of age who were diagnosed with Attention Deficit Hyperactivity Disorder (AD/HD), or Central Auditory Processing Disorder (CAPD). Children were administered a battery of neurocognitive tests and completed a self-report measure of personality. Parents completed several, AD/HD instruments pertaining to their children. The AD/HD instruments used in this study were the Attention Deficit Disorder Evaluation Scale-Home Version (ADDES), Attention Deficit Hyperactivity Disorder Test (ADHDT), and the Attention Problems and Hyperactivity scales from the BASC-Monitor (BASC-M). Of interest was how each AD/HD instrument compared to the DSM-IV, particularly in terms of the cross-consistency of AD/HD subtype classifications. The findings showed that the AD/HD instruments classified participants differently from the initial, DSM-IV entry diagnosis. Rates of agreement were better for some of the AD/HD instruments than for others yet there was little overall consistency. The neurocognitive measures used in the study were the Cognitive Assessment System-Basic Battery scales. The socioemotional measures used in the study were two parent-report scales from the BASC-M (Internalizing Problems and Adaptive Skills), and the child report scales from the BASC-Self Report of Personality. Results showed that the neurocognitive measures were relatively insensitive to AD/HD symptomatology while a nearly opposite trend was observed on the socioemotional measures. For the most part, participants classified as the ADHD-Combined Type (ADHD-CT), (regardless of which AD/HD instrument was used) had the most significant impairment in areas of social functioning and emotional symptoms across parent and self-reports.
Cultural Implications of Self-Other Agreement in Multisource Feedback: Comparing Samples from US, China, and Globally Dispersed Teams.
Application of multisource feedback (MSF) increased dramatically and became widespread globally in the past two decades, but there was little conceptual work regarding self-other agreement and few empirical studies investigated self-other agreement in other cultural settings. This study developed a new conceptual framework of self-other agreement and used three samples to illustrate how national culture affected self-other agreement. These three samples included 428 participants from China, 818 participants from the US, and 871 participants from globally dispersed teams (GDTs). An EQS procedure and a polynomial regression procedure were used to examine whether the covariance matrices were equal across samples and whether the relationships between self-other agreement and performance would be different across cultures, respectively. The results indicated MSF could be applied to China and GDTs, but the pattern of relationships between self-other agreement and performance was different across samples, suggesting that the results found in the U.S. sample were the exception rather than rule. Demographics also affected self-other agreement disparately across perspectives and cultures, indicating self-concept was susceptible to cultural influences. The proposed framework only received partial support but showed great promise to guide future studies. This study contributed to the literature by: (a) developing a new framework of self-other agreement that could be used to study various contextual factors; (b) examining the relationship between self-other agreement and performance in three vastly different samples; (c) providing some important insights about consensus between raters and self-other agreement; (d) offering some practical guidelines regarding how to apply MSF to other cultures more effectively.
A Culturally Sensitive Intervention in Pain Management Settings: Use of Dichos in Multi-Ethnic Pain Groups.
The present study explored whether use of Spanish language sayings, or dichos, improved group climate within multi-ethnic chronic pain groups. Use of this form of figurative language fits within psychological theory identifying use of metaphor as a means of promoting change and creating new meaning. Further, metaphor use is consistent with the broader aims of experiential therapy. Group climate was measured by group members' self reports using the Group Climate Questionnaire-Short Form. A pilot study involving Latino Americans in medical and non-medical contexts aided in categorizing dichos as high versus low-relevance. It was anticipated that clients would rate high-relevance sessions as involving greater engagement, and less conflict and avoidance than low-relevance groups. Participants were recruited from four multidisciplinary pain management clinics offering similar programs. Once every four to six weeks, group leaders were provided with a list of either high or low-relevance dichos, and were blind to the existence of dichos categories. Three hierarchical regression analyses were employed to determine whether dichos relevance, characterized as low, mixed or highly relevant, contributed to variance in group conflict, avoidance and engagement. Dichos familiarity was the last variable entered into the regression equation, with gender, ethnicity and acculturation score entered in sequential fashion. Consistent with predictions, low-relevance groups yielded higher conflict scores than all groups combined. Also, high-relevance groups predicted lower avoidance when compared to all groups. In contrast to hypotheses, high-relevance groups predicted lower ratings of group engagement when compared to all groups. Post-hoc analysis indicated the mixed-relevance groups yielded significantly higher engagement scores than the low and high-relevance groups. Implications of these findings are discussed in relation to impact on approaches to group therapy with Latino American clients, and within the chronic pain population. Limitations of the study and recommendations for future research are offered.
Culture and Mental Health Help-Seeking Attitudes in Mexico.
This study was designed to investigate 1) the cultural factors involved with Mexican citizens' attitudes toward seeking professional psychological help and 2) Mexican citizens' explanatory models of mental distress. Questionnaire data from 110 Mexican college students indicate that those who report a higher tolerance for stigma report lower endorsement of both the construct of personalismo and the machismo. Respondents who reported more interpersonal openness also reported a lower endorsement of the machismo construct. Participants from a large city reported significantly more stigma tolerance than those from a small city. Regression analyses reveal machismo as a significant predictor of stigma tolerance. Qualitative data was collected to provide additional in-depth information. Study results could be used to provide culturally appropriate mental health services.
Death and Ethnicity: A Psychocultural Study-Twenty-Five Years Later.
his study compares ethnic, age, and gender differences concerning attitudes and behaviors toward death, dying, and bereavement among Caucasian, African, Hispanic, and Asian American adult participants in north Texas with the results of a 1976 study by Kalish and Reynolds on death attitudes and behaviors of Caucasian, African, Mexican, and Japanese American adult participants in Los Angeles, California. A modified version of Kalish and Reynolds' study questionnaire was administered to 526 respondents (164 Caucasian, 100 African, 205 Hispanic, and 57 Asian Americans) recruited from community and church groups. Findings of this study were compared with those of Kalish and Reynolds in specific areas, including experience with death, attitudes toward one's own death, dying, and afterlife, and attitudes toward the dying, death, or grief of someone else. Data was analyzed employing the same statistical tools as those used by Kalish and Reynolds, i.e., chi square calculations, frequencies, percentages, averages, and analyses of variance. As compared with the earlier study, results indicated that this study's participants were less likely to have known as many persons who had died recently or to state they would try very hard to control grief emotions in public. Present study participants were more likely to have visited dying persons, to want to be informed if they were dying and believe that others should be informed when dying, to prefer to die at home, to have made arrangements to donate their bodies or body parts to medicine, to have seriously talked with others about their future deaths, to consider the appropriateness of mourning practices and the comparative tragedy of age of death from a relative standpoint, and to want to spend the final six months of their lives showing concern for others. Between study differences were found in ethnic group, age group, and gender group comparisons. Within study …
Decisional Balance Scale: Restructuring a Measurement of Change for Adolescent Offenders
The transtheoretical model has a substantial history of measuring the change process. Hemphill and Howell validated the Stages of Change Scale (SOCS) on adolescent offenders. The current study expands their research by developing an additional component of the TTM, the Decisional Balance Scale for Adolescent Offenders (DBS-AO). This measure assesses movement through the stages of change and provides insight into mechanisms through which adolescent offenders attempt to change their criminal behaviors. Two hundred thirty-nine adolescent offenders at the Gainesville State School completed the SOCS, DBS-AO, Paulhus Deception Scales (PDS), and the Antisocial Process Screening Device (APSD). The study found the DBS-AO is psychometrically sound, demonstrates excellent reliability and has an underlying three-factor solution: Cons, Pros-Self, and Pros-Others. Offenders in the early stages of change scored significantly higher on the Cons scale. Offenders actively changing their behavior scored significantly higher on the Pro-Self and Pros-Other scales.
Deficits in Miranda Comprehension and Reasoning: The Effects of Substance Use and Attention Deficits.
Each year, an estimated 318,000 defendants who do not comprehend the Miranda warnings waive their rights and provide incriminating evidence without the protection of counsel (Rogers, 2008), which make Miranda-related competencies one of the most pervasive pretrial issues. A wide range of issues could potentially affect an individual's capacity to provide a knowing and intelligent waiver. Previous Miranda research has focused narrowly on the effects of cognitive and developmental factors. The current study added to the Miranda literature by examining the impact of two highly prevalent conditions found in correctional populations, attention deficits and substance abuse. Adult defendants in custody (N = 118) were evaluated within 36 hours of arrest in order to assess both chronic psychological disorders and situational variables. Results indicate that attention deficits have a significant impact on defendants' ability to provide a knowing Miranda waiver, whereas substance use profoundly affected their reasoning about Miranda waiver decisions. This study represents the first systematic investigation of the effect of transient mental states on Miranda-related abilities with criminal defendants. Important implications for forensic practice are addressed.
Dementia, Diabetes, and Depression: Relationship to Cognitive Functioning
The number of adults in the United States who are age 65 or older is rapidly increasing. With longer lifespan comes an increase in chronic diseases such as dementia, diabetes, and depression. This study used archival data from a larger study conducted at the Memory Clinic at John Peter Smith County Hospital in Ft. Worth, Texas to examine several hypotheses and research questions related to the influence of type of dementia, presence of Type II diabetes, and presence of depression on neuropsychological test performance. First, this study attempted to identify specific patterns of performance on neuropsychological measures for those with Alzheimer's dementia (AD), vascular dementia (VaD), or mild cognitive impairment (MCI). The results indicated that those with MCI perform better than those with AD or VaD on all neuropsychological measures, and that those with VaD perform better than those with AD on a measure of verbal memory. Another purpose of the study was to determine how the presence of Type II diabetes affects this pattern of functioning; the overall finding in this study was that the presence or absence of diabetes did not affect performance on measures of cognitive functioning. Additionally, the study attempted to add to literature examining the influence of depression on older adults with diabetes and/or dementia; no significant differences emerged.
Demographic Variables and Their Relation to Self-Concept in Children with and Without Attention-Deficit/Hyperactivity Disorder
The proposed study examined differences in self-concept between ADHD (n = 61) and non-ADHD boys and girls. Participants included 108 children between 6 and 11 years old. Children completed the Self Description Questionnaire-I, and teacher reports of child competence were obtained. Girls reported lower physical ability and mathematics self-concept than boys. The results also indicated that ADHD girls may be more susceptible to low physical ability and mathematics self-concept than control children or ADHD boys. Teachers also rated ADHD girls as having lower scholastic competence than the other three groups. Teachers reported significant differences in level of competence based on ADHD status. The implications of the current study and directions for future research will be presented.
Depression, Activities of Daily Living, and Retirement
Depression is a common clinical and subclinical psychiatric disorder in the middle-age to older adult population. This study examined the relationship between depression and activities of daily living (ADLs) in middle-age to older adults. This study examined longitudinal data from the 1998, wave 4, and 2000, wave 5, of the Health and Retirement Study (HRS), a National Panel Study sponsored by the National Institute on Aging. A negative cross-sectional and longitudinal relationship between higher ADL scores and depression was hypothesized. A goal of the present study was to determine the temporal precedence of these two constructs using a cross-lag panel design to first examine the cross-sectional relationship between ADLs and depression at time-one and at time-two, and then the time-one to time-two longitudinal relationships to examine temporal precedence possible causal relationships. Finally, differences in these correlational relationships by retirement status and then by marital status were tested. There were several interesting findings, including those who were retired in both 1998 and 2000 reported fewer ADLs (i.e., worse functioning), but also reported better health than those who were working in both 1998 and 2000. Similarly, those people who were not married in both 1998 and 2000 reported fewer ADLs but better health than those who were married in both 1998 and 2000. Married individuals reported fewer depressive symptoms than those who were not married.
Design and Empirical Analysis of a Model of Empowering Leadership.
Mid-level leaders are often expected to implement employee empowerment initiatives, yet many do not have a clear understanding of how to empower employees. To address this issue, a model of empowering leadership was developed. The model presents specific, actionable behaviors that a leader should perform in order to empower employees. The model comprises 13 factors built around the areas of ability, accountability, and authority. First, leaders must ensure employees have the ability to be empowered. To do so, they must (a) build employee organizational knowledge, (b) provide access to pertinent information, (c) assure employees have the necessary skill set, and (d) identify and provide needed resources. Second, leaders must create systems of accountability for employee outcomes by (e) setting a standard of continuous improvement, (f) recognizing and rewarding good work, (g) regularly evaluating employee efforts, and (h) providing continuous feedback on employee efforts. Third, leaders should provide employees with the authority to be empowered by (i) serving as advocates of employee efforts, (j) providing an environment that is conducive to empowerment, (k) setting a clear and consistent direction to guide employee efforts, and (l) building systems and structures to support employee empowerment. The thirteenth factor of the model is a constant focus on the work, because without the work there is no real reason for empowerment. A review of the existing literature suggests a need for empirical research on empowerment concepts. This dissertation empirically investigated empowering leadership with two studies. The first focused on development of measures, while the second focused on model development. The measurement study supported the three general areas of ability, accountability, and authority, although the accountability area was weak. Results of the model examination study indicated that the model largely behaved as expected, but did require some modification. Based on the model exploration, four of the …
The Detection of Neuropsychological Malingering
The present study compared the responses of a group of simulating malingerers who were offered a monetary incentive to feign symptoms of a head injury, with the responses of head injured groups both with and without litigation, a forensic parole group, and an honest-responding control group. The following six neuropsychological measures were utilized: Rey 15-Item Memory Test, Controlled Oral Word Association Test, Finger Oscillation Test, WAIS-R Neuropsychological Instrument (Vocabulary, Information, and Similarities subtests), Booklet Category Test, and Wisconsin Card Sorting Test. The statistical concepts of floor effect, performance curve, and magnitude of error were examined. Additionally, the statistical differences in the responses of the five groups were analyzed to determine cutting scores for use in distinguishing malingerers from nonmalingerers.
Development and Psychometric Validation of the State-Trait Spirituality Inventory
The present study contributes to the widening body of spirituality research by conceptualizing it as a state-trait construct. A new measure of spirituality, the State-Trait Spirituality Inventory (STSI), was created and validated according to psychometric methods of test construction. In its current form, the STSI contains seven state spirituality items and six trait spirituality items. A thorough review of the literature identified common themes in spirituality definitions and assisted in developing definitions of trait and state spirituality. Internal consistency for the trait scale was .88 and for the state scale, .68. Good test-retest reliability was found with coefficients of .84 for trait spirituality and .81 for state spirituality. Results from a preliminary undergraduate sample as well as from the validation sample yielded a two-factor solution. In general, items determined by expert panels as trait items loaded on one factor and items deemed to be state items loaded on the second factor. Multitrait multimethod analysis yielded mixed findings for convergent, divergent, and concurrent validity for the spirituality and religiosity traits. Methods consisted of paper-and-pencil cognitive and behavioral measures. Cognitive measures were more likely to support convergent/divergent validity than were behavioral measures. A major emphasis in the study was to determine whether state and/or trait spirituality were able to predict current health status and provide evidence for predictive validity. Positive relationships were identified between trait spirituality and the mental health measures of the Short Form-36® (SF-36). In contrast, it was negatively related to the Role-Physical scale. State spirituality was inversely related to the Physical Component scale. These findings are discussed within the context of minimal research using the SF-36 and spirituality measures. The MTMM analysis was limited by available spirituality and religiosity measures that contain only cognitive or behavioral items. Suggestions for future research are offered.
Development of a Multidimensional Approach to Understanding Youthful Offenders: The Influence of Psychosocial and Personality Risk Factors
This study employed a multivariate, multidimensional approach to understanding psychosocial and personality variables associated with institutional maladjustment and recidivism among youthful offenders. Participants included nine hundred serious and chronic male youthful offenders incarcerated in the Texas Youth Commission (TYC); sample sizes varied by analysis. Empirically-validated psychosocial factors (e.g., intelligence, home approval status), past criminal history variables, and two self-report personality measures of empathy and hostility were entered into hierarchical regression and structural equation modeling (SEM) analyses to predict institutional behavior and recidivism at one- and three-year intervals after release from the TYC. Confirmatory factor analysis of the personality measures revealed one underlying factor indicative of their theoretical constructs of empathy and hostility. Some differences were noted between youth in the specialized treatment programs; however, effect sizes were small to moderate. Overall, regression and SEM results indicated the variables accounted for a meaningful proportion of the variance in the outcomes. Specifically, although length of stay in the TYC was associated with institutional behavior, younger age of onset, higher hostility, and greater home disapproval also contributed significantly. Past criminal behavior was predictive of future reoffending, but lower empathy, greater home disapproval, and younger age of onset accounted for a substantial portion of the variance in recidivism. Institutional maladjustment served as a mediator between the psychosocial and personality variables and the recidivism outcomes. Treatment implications are provided, including a discussion of the tenuous association between length of sentence and recidivism and an emphasis on the importance of evaluating dynamic personality and psychosocial variables beyond static measures of past behavior.
Developmental Stressors and Associated Coping Skills in the Development of Disordered Eating in College Females
There is a lack of clarity in the current literature in how potential etiological factors interact and result in disordered eating. The purpose of this study was to examine an expanded model of Personality, Social Support, Appraisal/Coping Processes, Abuse History, Internalization of Sociocultural Standards, Psychological Disturbances, and Body Disparagement in the development of disordered eating. The current model was evaluated using 276 women in their transition to college, a time period highly associated with symptoms believed to increase a woman's risk for the development of disordered eating including perceived difficulty coping, weight gain, and negative affect. Structural equation modeling was used to allow simultaneous examination of the causal relationships between the factors. Structural analyses confirmed that college women with previous stressful experiences appraised the adjustment to college as more stressful and reported feeling less able to cope with the transition. Those women who identified the transition as overwhelming were also aware of increased negative mood and psychological states since beginning the school semester. Further, women with previous traumatic sexual experiences appeared to be at additional risk for increased negative affective symptoms. The resulting model confirmed that those women who experience negative mood states and those that endorse strong internalization of cultural values regarding attractiveness encountered increased dissatisfaction and disapproval of their bodies. Finally, women with higher levels of body concern engaged in more eating behaviors associated with disordered eating. The roles of personality functioning and perceived social support could not be identified in the developmental model. The predictive links between constructs in the resulting model provide meaningful information regarding the transition to college and associated risks for development of disordered eating. Validation of the model in an independent sample would provide confirmation of these relationships and longitudinal research examining females' attitudes across crucial developmental periods might provide important information regarding …
Differences in Depressive Symptoms as a Function of Gender, Roles, and Rumination
Research indicates that women are more likely to experience depression than are men. The current study examined the effects of gender, socialized gender roles, rumination, and neuroticism on symptoms of depression in young adults. As predicted, rumination mediated the relationship between gender and depression, and socialized gender roles had a greater explanatory power for rumination, neuroticism, and depression than did gender. Contrary to predictions, rumination did not mediate neuroticism's effects on depression. Structural equation modeling reveled that rumination-on-sadness positively predicted neuroticism and depression. However, rumination-in-general, while positively predicting neuroticism, negatively predicted symptoms of depression. Finally, once socialized gender roles, rumination, and neuroticism were controlled, male gender was modestly predictive of depression.
Differences in Perceptual-motor Functioning Between Blind and Sighted Adults: a Neuropsychological Perspective.
The purpose of the study was to explore perceptual-motor differences between blind and sighted adults from a neuropsychological perspective, and to analyze differences within the blind group. Perceptual-motor abilities were examined using the Comprehensive Vocational Evaluation System (CVES), a vocational rehabilitation and neuropsychological battery designed for use with blind populations. The data were processed using Analysis of Covariance. Results showed that sighted persons had better motor abilities, while persons with blindness were more skilled at haptic identification of shape and texture. Analysis within the blind group showed that texture identification skills are better when blindness occurs earlier in life and to the extent that the blindness is total. Later onset blindness and the retention of some functional vision may not lead to a refocusing of attentional states necessary to develop haptic images. New neural connections may develop in persons with congenital/total blindness, a hypothesis in line with recent neuroradiological findings that occipital lobe activation occurs when congenitally blind individuals engage in tactile processing tasks. One implication of the findings is that teaching individuals who retain some functional vision to read Braille is probably counterproductive. These individuals would be better served by learning to use a CCTV and large print books. Future researchers should examine blindness from a multivariate perspective, examining subsets of blind groups based on age at onset, visual status, and other pertinent variables. Other implications are discussed and recommendations for future research are provided.
Differential Scoring Patterns on the Clock Drawing Test: a Comparison of Vascular Dementia and Alzheimer's Dementia.
This study examined differences in scoring patterns among those diagnosed with Alzheimer's dementia and vascular dementia on the clock-drawing test. Archival clock drawing data was retrieved on 279 patients presenting at a county hospital-based memory clinic. Analysis of drawings was based on frequency of qualitative errors, as well as an overall quantitative score. Mean comparisons found those patients with Alzheimer's dementia to perform worse on both quantitative and qualitative scoring measures. However, Pearson's chi-squared test revealed a significantly higher rate of spacing errors among subjects with vascular dementia. Such lends support to my hypothesis that impaired executive functioning in vascular dementia patients would lead to poor qualitative performance. Logistic regression found significant predictive ability for the qualitative criteria in diagnosis (χ2 = 25.49, p < .001), particularly the rate of omission (z = 8.96, p = .003) and addition errors (z = 7.58, p = .006). Such findings hold important implications for the use of qualitative criteria in cognitive screening assessments.
Differentiating Connectedness and Neediness as Two Forms of Dependency
The Depressive Experiences Questionnaire Dependency scale has been used extensively by researchers to measure a personality style vulnerable to depression. However, subsequent studies have demonstrated that the DEQ-Dependency is composed of two distinct forms of dependency, "Connectedness" and "Neediness", which may have different implications for mental health. While Connectedness may represent a more mature form of dependency than Neediness, it may not represent an entirely "healthy" form of relatedness as previously suggested. Although these scales are being used in current research, it is not yet clear what they represent. One goal of the present study was to further examine the construct validity of Connectedness and Neediness in order to differentiate these constructs. Gender, self-efficacy, relationship quality, and interpersonal behavior were chosen because of their proposed significance in differentiating forms of dependency. 265 undergraduates completed the DEQ, Beck Depression Inventory (BDI), the Mutual Psychological Development Questionnaire (MPDQ), and the Inventory of Interpersonal Problems (IIP). Overall, results supported the importance of distinguishing between these two factors of dependency. Neediness was associated with more maladaptive correlates for both genders. The picture is more complex for Connectedness, however, and it appears that Connectedness is less healthy for women than for men.
Differentiation of Central Auditory Processing Disorder and Attention-Deficit Hyperactivity Disorder in Children and Adolescents
The purpose of this study was to determine whether or not children diagnosed with Attention-Deficit Hyperactivity Disorder (ADHD) or Central Auditory Processing Disorder (CAPD) can be distinguished from one another on the basis of both objective and subjective assessment of attention and behavior. First, children and adolescents diagnosed with ADHD, CAPD, and concomitant ADHD/CAPD were compared to participants with emotional problems on measures of attention/concentration, depression, anxiety, and parental reports of internalzing and externalizing behaviors. Overall, statistical analyses did not reveal significant differences between performances of children diagnosed with ADHD and those diagnosed with CAPD. However, clinical comparisons across groups of children diagnosed with ADHD, CAPD, comorbid ADHD/CAPD and Affective Disorders revealed condition-specific clinical profiles, thus providing some support for CAPD as a distinct clinical entity. Second, exploratory cluster analysis was performed to further investigate the relationship between ADHD and CAPD. This procedure lead to the identification of four distinct clusters. However, analyses of these clusters revealed no distinct pattern of performance for children diagnosed with either ADHD or CAPD. Rather, participants with these diagnoses were evenly distributed throughout the clusters. Additionally, no cluster clearly represented the expected clinical profile for a diagnosis of CAPD- namely, significant auditory attentional/processing problems in the absence of other attentional difficulties. Implications for the assessment and treatment of childhood attentional disorders are discussed and recommendations for future research provided.
