Adolescent Self-Mutilating Behaviors: Experiential Avoidance Coupled with Imitation?
Repetitive self-mutilation (RSM) has become increasingly prevalent among adolescents. Empirical research has pinpointed several correlates of this behavior, but the initiation and maintenance of RSM among adolescents are not well understood. The experiential avoidance model (EAM) proposes that self-mutilation is a behavior that allows for the avoidance or alteration of unwanted internal experiences, and that it is negatively reinforced with repetition. The current study explored the usefulness of the EAM as an explanatory theory for adolescent RSM, with the additional incorporation of issues of social context. Adolescents (N = 211) from three school-based samples completed self-report questionnaires. One-third of students reported at least one incident of purposeful, non-suicidal self-mutilation and 16% had engaged in self-mutilation repeatedly within the past 6 months. Both regression and group analyses indicated that adolescents who engage in RSM report greater psychological distress, a greater incidence of functionally equivalent behaviors, and greater exposure to self-mutilation among peers and/or in the media, when compared to their counterparts who have not engaged in RSM. Suicidal ideation/behaviors were consistently the strongest predictors of current self-mutilation behaviors. Clinical implications, limitations, and suggestions for future research are discussed.
Adult Attachment and Posttraumatic Growth in Sexual Assault Survivors.
Posttraumatic growth, defined as positive psychological changes in the aftermath of adversity and suffering, is a relatively recent focus in psychological research. The addition of this concept to the literature has provided a new, more resiliency-based framework through which to view survivors of various forms of trauma. Despite estimates that over half of all sexual assaults are not reported to the authorities, current crime statistics indicate that 1 in 4 women are sexually assaulted in their lifetime (Campbell & Wasco, 2005). Given the large percentage of the population that is impacted by sexual assault, it is essential that professionals better understand the factors that influence the successful healing and growth that can occur post-trauma. The purpose of this study was to further expand the literature on posttraumatic growth in sexual assault survivors by considering this phenomenon through the lens of attachment theory. Specifically, this study tested a proposed model of the inter-relationships among subjective and objective perceptions of threat during the sexual assault, adult romantic attachment, and posttraumatic growth. It was hypothesized that adult romantic attachment and parent-child attachment would mediate the relationship between subjective, or perceived threat, defined as the victim's perception of life threat, and objective threat, defined as the severity of the sexually aggressive act perpetrated on the victim, and posttraumatic growth. Finally, it was hypothesized that subjective threat appraisal would better predict posttraumatic growth than objective threat appraisal. Contrary to hypotheses, results of the study indicated that adult romantic attachment and parent-child attachment did not mediate the relationship between subjective and objective threat appraisal and posttraumatic growth. Thus, both path analytic models were not viable. However, exploratory analysis indicated that both subjective and objective threat appraisal were directly related to posttraumatic growth, with subjective perceived threat appraisal accounting for more of the variance.
Affective and cognitive components of job satisfaction: Scale development and initial validiation.
Job satisfaction is one of the most commonly studied variables in the organizational literature. It is related to a multitude of employee-relevant variables including but not limited to performance, organizational commitment, and intent to quit. This study examined two new instruments measuring the components of affect and cognition as they relate to job satisfaction. It further proposed including an evaluative (or true attitudinal) component to improve the prediction of job satisfaction. Results provide some evidence of both two and three factor structures of affect and cognition. This study found minimal support for the inclusion of evaluation in the measurement of job satisfaction. Affect was found to be the single best predictor of job satisfaction, regardless of the satisfaction measure used. Further development is needed to define the factor structures of affect and cognition as well as the role of these factors and evaluation in the prediction of job satisfaction.
Agreement Between Self and Other Ratings in Multi-Rater Tools: Performance, Alternative Measures, and Importance.
Multi-rater tools also referred to as 360-degree feedback tools, are frequently used in addition to traditional supervisory appraisals due to sources (i.e., supervisor, peer, direct report) unique perspectives and opportunities to view different aspects of job performance. Research has found that the differences among sources are most prevalent between self and other ratings, and the direction of agreement is related to overall job performance. Research has typically focused on one form of agreement, the direction of an individual's self-ratings compared to others' ratings. The current study expanded on past research on rater agreement using a data set (n = 215) consisting of multi-rater data for professionals participating in a leadership development process. The study examined the ability to predict job performance with three different measures of self-other agreement (i.e., difference between overall mean scores (difference), mean absolute difference across items (difference), and mean correlation across items (similarity)). The study also examined how the relationships may differ across performance dimensions. The final purpose was to explore how the importance of the performance dimensions, as rated by the participant, may moderate the relationship between self-other agreement and job performance. Partial support for study's hypotheses was found. The direction and difference measures of agreement on the overall multi-rater tool and performance dimensions accounted for a significant amount of the variance in job performance. The relationship between the similarity measure of agreement and job performance, and the moderating effect of importance were not supported in the current study.
Association Between Folate, Vitamin B12 and Cognitive Performance in Demented Elderly.
Dementia is prevalent among elderly people. As the world population ages, it is projected that the number of people affected by dementia may triple in the next 50 years. Over the last two decades, research has focused on identifying potentially modifiable risk factors in development and progression of dementia, such as vitamin B12 and folate. Results concerning the effects of low folate and vitamin B12 on cognitive performance are mixed. The main objective of the present study was to investigate the effects of vitamin deficiency on cognitive functioning in a clinical sample of elderly individuals with cognitive problems using a comprehensive neuropsychological assessment. A retrospective chart-review was performed on the 102 records of patients from the Geriatrics Clinic at the University of North Texas Health Science Center who presented with cognitive deficits. Charts were reviewed to obtain data on vitamin supplementation, vitamin status, history of chronic conditions and other biochemical data. The available database was used to obtain data on neuropsychological assessment. The study demonstrated mild association between vitamin B12 and folate status and cognitive deficits. There appeared to be a higher cut-off level that is above the traditionally used levels for vitamin B12 and folate deficiency concentrations at which cognitive deficits became more pronounced. Clinical applications, limitations and suggestions for future research were discussed.
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.
The Effectiveness of the Geriatric Depression Scale to Distinguish Apathy From Depression in Alzheimer's Disease and Related Dementias.
Early detection of Alzheimer's disease (AD) and related dementias in the elderly is critical for improving treatment methods and is a necessary component for improving public health interventions. One of the earliest and most common behavioral syndromes of AD is apathy and is associated with executive dysfunction. Apathy in AD is often misdiagnosed as depression due to an overlap in symptoms. Studies that have found depression to be associated with executive dysfunction have not always controlled for the presence of apathy. The Geriatric Depression Scale (GDS) is a widely used instrument designed to assess depression in the elderly. This study utilized the GDS and a set of standard neuropsychological instruments to investigate the relationship between apathy, depression, and executive functions in individuals with AD and related dementias. The first objective of this study was to determine if apathy has a greater impact on executive functions compared to depression in AD and related dementias. The second objective was to determine the effectiveness of the GDS as a screen for apathy. The results of the analyses did not support the hypotheses. However, exploratory analyses suggested a possible non-linear relationship with apathy and various levels of dementia severity. Exploratory analysis also suggested mean levels of endorsement for apathy varied by diagnosis. Further research is warranted to investigate this relationship and the GDS endorsement patterns for caregivers regarding their impression of the demented individual.
The Effects of Sequential Versus Referential Montage Neurofeedback Amplitude Training on Qeeg Measures of Phase and Coherence.
An important clinical research question to be answered in the field of neurofeedback (NF) is whether amplitude training affects connectivity between cortical sites. This study hypothesizes that, following NF amplitude training, there will be a difference in QEEG coherence and phase measures between NF training done using referential montages and using sequential montages. The study examined case files of 16 adult clients from the University of North Texas Neurotherapy Lab who had received NF training that consisted of either referential or sequential placement amplitude training (no coherence training) and who received both pre- and post- treatment QEEGs. Sixty-eight percent of the cases consisted of referential placements, while 34% of the cases consisted of sequential placements. All frontal site phase and coherence abnormal z-scores at pre-treatment were converted to deviation scores and compared by general linear model analysis of variance to post-treatment deviation scores. Effect size r-values and eta square values indicate that differences between referential and sequential electrode placements after NF amplitude training are moderately high. This study shows that referential placements tend to increase phase scores and decrease coherence scores, while sequential placements tend to decrease phase scores and increase coherence scores.
Efficacy of neurofeedback for children with histories of abuse and neglect: Pilot study and meta-analytic comparison to other treatments.
This two-part study investigates the effectiveness of neurofeedback training for reducing behavioral problems commonly observed in abused/neglected children, and compares its efficacy to other treatment interventions with this population. Neuro-developmental sequelae of early relationship trauma are explored as an etiological framework for understanding disturbed affect-regulation, which appears central to the behavioral and emotional difficulties commonly experienced by this pediatric population. It is suggested that neurofeedback teaches children to self-regulate brain rhythmicity mechanisms, which in turn affects global improvements in behavior and mood. The pilot study utilizes records of 20 children removed from their biological homes by Child Protective Services. Children were assessed prior to treatment using the Child Behavior Checklist (CBCL) and the Test of Variables of Attention (TOVA), and again after 30 sessions of individualized, qEEG-guided neurofeedback training. A t-test analysis of pre- and post-scores was computed, and indicated significant improvements following treatment. A meta-analysis of existing literature on treatment interventions with abused/neglected children provides individual and aggregate effect sizes for 33 outcome studies with this clinical population, and contextualizes the results of the present pilot study within other empirically validated treatment modalities. Establishment of an overall effect size for treatment for this pediatric population provides a needed method of comparing research results across studies when control groups may not be ethical or feasible.
An empirical investigation of the influence of age, gender, and occupational level on stress perceptions, job satisfaction, organizational commitment, and turnover.
This study investigated relationships of age, gender, and supervisor level with job satisfaction, organizational commitment, stress perception, and turnover intention. The demographics were hypothesized to moderate the stress-satisfaction and commitment-turnover relationships. Hypotheses were tested using both parametric and non-parametric bootstrap methods. Subjects were taken from a national survey of 2,663 public sector IT workers. Missing data were imputed using NORM software. Ordinary least squares (OLS) regression indicated a significant direct effect from all main variables and covariates, except for age on turnover intent. No mediating effects were found. Age-Commitment was the only significant higher order modifier relationship, although Gender-Commitment explained substantial variance. LMG statistic results enabled the predictors to be rank ordered with confidence intervals. Best subset bootstrap regression explored all possible predictor orders to confirm which model explained the most variance. The original model and predictor sequence were confirmed. The bootstrap AIC statistic provided a model which maximized explained variance while optimizing parsimony. Since only age had a mediating effect, Hypotheses 1 and 2 were not supported. All other hypotheses were partially confirmed.
Evaluation of the Quick Inventory of Depressive Symptomatology - Self-Report (QIDS-SR) in a spinal cord injury population.
Spinal cord injury (SCI) is an acute and devastating event that results in significant and permanent life changes for the individuals who are injured, as well as their families and friends. Depression has received more attention from clinicians and researchers than any other psychological issue among persons with SCI. Measurement of depression in this population has a variety of methodological issues, including inconsistent assessments used (self-report versus clinical interviews), varying definitions of depression, inclusion and exclusion of physical symptoms in the assessment process, and use of measures that do not represent DSM-IV criteria for major depressive disorder. The primary goal of this study was to evaluate the Quick Inventory of Depressive Symptomatology - Self-Report (QIDS-SR) and provide descriptive analyses of this measure with persons with SCI. Results showed that somatic symptoms were more frequently endorsed than psychological symptoms in this population. Additionally, scores on the QIDS-SR were significantly associated with a depression diagnosis in the patient's medical chart. However, QIDS-SR scores were not found to be correlated inversely with quality of life scores as predicted. The QIDS-SR was shown to have good internal consistency and convergent validity with patients with SCI. However, it failed to demonstrate construct validity. The QIDS-SR has the potential to be a valid measure with this population and further analysis of the psychometric properties with patients with SCI is warranted.
Examining an eating disorder model with African American women.
In the current study, I examined the general sociocultural model of eating disorders that suggests that sociocultural pressures leads to internalization, which in turn leads to body dissatisfaction and ultimately disordered eating. Because I am testing this model with a sample of African American women, I also am including acculturation as a variable of interest. Specifically, I hypothesized that (a) the experience of more societal pressure to be thin will be related to greater internalization, (b) higher levels of acculturation will be related to greater internalization, (c) internalization of the thin ideal will be directly and positively related to body image concern, and (d) body image concern will be associated with higher levels of disordered eating. It was determined that there is a direct, negative relationship between Level of Identification with Culture of Origin and Internalization. Perceived Pressure was directly and positively related to both Internalization and Body Image Concerns. Body Concerns and Internalization were both directly and positively related to Disordered Eating. These findings suggest that although many of the same constructs related to disordered eating in other ethnic groups are also related to disordered eating among African American women, the relationships between the factors differs across racial/ethnic groups. This information can help clinicians and researchers to better treat and understand the nature of disordered eating behavior and correlates among African American women.
An exercise in story repair: A guided written disclosure protocol for fostering narrative completeness of traumatic memories.
The present study sought to build on the large body of past research into written disclosure of traumatic memories. This research has consistently found that participants who write about their traumatic experiences realize long-term physiological and psychological health benefits. More recently, it has been found that those participants who realize the most benefits are those who progressively include more elements of a good narrative, or story, in their writing about a traumatic experience over several sessions. Therefore, research has begun to examine the role of language and the structure of language in the health benefits gained from written disclosure of traumatic memories. A guided written disclosure protocol was designed for the present study, which sought to aid participants in supplying an increasing amount of narrative structure to their written disclosures of a single traumatic experience. Participants (N = 30) completed several measures of psychological and physiological health prior to and one month after completing the guided written disclosure protocol. Analyses revealed that participants who completed all four writing sessions showed statistically significant reductions in symptoms of general psychological distress, obsessive-compulsive symptoms, and intrusive and avoidant symptoms related to the traumatic experience. No significant self-reported physiological health benefits were found. The clinical and research implications of these findings are discussed.
An Exploration of the Relationship between Worry and Other Verbal Phenomena
This study hypothesized a direct relationship among three verbal phenomena: derived relational responding, verbal intelligence, and worry. It also hypothesized that experiential avoidance would mediate the relationship between derived relational responding and worry. Overall, results from this study failed to support a relationship between worry and the other two verbal phenomena, however, results did support a relationship between derived relational responding and verbal intelligence. Additionally, results indicated a significant relationship between experiential avoidance and worry. Future research should clarify the relationship among the three primary variables of interest, improve measurement of these variables, be more sensitive to external validity, and promote the study of acceptance-based treatments that target experiential avoidance.
Functions of self-injurious thoughts and behaviors within adolescent inpatients.
The primary interest of this investigation concerned the self-injurious thoughts and behaviors (SITBs) of inpatient adolescents. Previous researchers have provided descriptive information regarding either automatic (or intrinsic) and social components using the Self-Injurious Thoughts and Behaviors Interview (SITBI). However, the presence and trends of these components have not firmly been established, suggesting the need to explore this area further. Eighty-two adolescent inpatients were selected and interviewed using the SITBI to evaluate the predictive ability of self-reported self-injurious behavior with regard to social and automatic, negative and positive functions. Results showed that depending on the type of thought or behavior displayed one could discern the motivation behind their actions. Automatic-Negative was seen to have the strongest relationship across all SITB behaviors while Automatic-Negative was not found to be relatively low compared to other SITB behaviors. Both Social-Positive and Social-Negative were found to be present in moderate relationships compared to Automatic in general.
Health message framing : motivating cardiovascular risk factor screening in young adults.
As the leading cause of death in the United States, coronary heart disease (CHD) is a growing public health problem, despite the fact that many risk factors for the disease are preventable, especially if addressed early in life. The purpose of the current study was to examine the effects of loss-framed versus gain-framed versus information-only health messages on both intention to attend and actual attendance at an appointment to get screened for CHD risk factors (i.e., hypertension, diabetes, and dyslipidemia). It was hypothesized that a population of young adults would be more likely to view screening for CHD risk factors as a low-risk, health-affirming behavior as opposed to a risky, illness-detecting behavior and would thus be more strongly influenced by gain-framed messages than loss-framed messages. Additional goals included the exploration of the extensively researched individual health beliefs of perceived threat (as defined by the health belief model) and health locus of control as they relate to message frames. One hundred forty-three undergraduate students were randomly assigned to either the loss-framed, gain-framed, or information-only control conditions. Framing manipulation checks revealed that participants failed to discern differences in the tone and emphasis of the experimental pamphlets. As a result, no tests of framing effects could be conducted. Sixteen (11.2%) of the 143 participants who participated in Part 1 of the experiment participated in Part 2 (i.e., attended a risk factor screening appointment). Multiple regression analysis revealed risk index, age, and powerful others health locus of control as significant predictors of screening intention. Gender was the only demographic or health related variable that was significantly related to screening outcome, such that women were more likely to get screened than men. Limitations and recommendations are discussed.
Heart rhythm variability in persons with chronic pain.
The present study evaluated the utility of heart rhythm coherence (HRC) feedback to reduce the reported pain intensity of patients enrolled in a multimodal pain management program. Participants were recruited and assigned to a usual treatment group (UT) or a heart rhythm coherence feedback group (UT+HRC). It was hypothesized that UT+HRC participants who achieved heart rhythm coherence would report a reduction of pain intensity, as measured by the McGill Pain Inventory. For those whose pain intensity decreased, it was also expected that their self reported levels of depression as measured by the Beck Depression Inventory-Second Edition and state anger as measured by the State Trait Anger Inventory would decrease. It is also hypothesized that with a reduction in pain levels, anger, and depression, blood pressure would also decrease among those who had high blood pressure prior to the intervention. Multivariate analyses of variance (MANOVA) were used to investigate the relationship between treatment condition, coherence status and pain levels. A series of independent t-tests were utilized to investigate the change in pain, depression, and state anger from baseline to posttest, followed by Pearson product moment correlation coefficients on difference scores to understand the relationship between the outcome variables for Hypothesis 2. Standard multiple regression analyses were computed using difference scores to determine if the outcome measures were significant predictors of systolic blood pressure and diastolic blood pressure. Results indicated a failure to reject the null with regard to hypothesis one. No relationship between treatment assignment, coherence status or pain levels were found. Hypothesis 2 was partially supported. Although there was a positive significant relationship between depression and anger when utilizing difference scores, these affective measures were not related to difference scores on either pain measure. In regard to Hypothesis 3, there was also a failure to reject the null. None of …
The impact of training and learning on three employee retention factors: Job satisfaction, commitment and turnover intent in technical professionals.
The purpose of this study is to explore the benefits of providing employee training and learning beyond the specific content covered in such interventions, and how personality constructs might moderate those benefits. Training refers to the imparting of specific knowledge and tasks. Learning involves processes and skills that support on the job learning experiences. This study builds on previous research linking training and development to increased job satisfaction, and reduced turnover intent, by considering additional factors. The relationships between independent variables training, learning, task variety and task significance and outcome variables job satisfaction, commitment and turnover intent are assessed. Personality constructs of need for achievement and growth need strength are explored as possible moderating variables. This research was conducted using archival data (N = 500) collected from technical professionals employed by fourteen organizations in the Southwest United States. Both task variety and task significance were found to significantly predict all three outcome variables. Growth need strength was found to moderate the prediction of commitment by task variety. Need for achievement was found to moderate the prediction of job satisfaction, commitment and turnover intent by training and learning. Need for achievement was also found to moderate the prediction of both commitment and turnover intent by task significance.
Individual attachment styles and the correspondence/compensation hypotheses in relation to depression and depressive experiences.
Two hundred twenty individuals participated in the present study from a university population. The study examined the relationship among attachment styles to caregivers, relationship with God, depressive symptomology, and depressive experiences. Attachment theorists have suggested a connection between childhood attachment to caregivers and current attachment to God through the idea that individuals have "working models" that form how they interpret present relationships. For the most part, the results of the current study supported the idea of correspondence between attachment to caregiver and attachment to God. Individual attachment styles to caregivers matched their attachment style to God. However, when caregiver religiousness was included as a moderating variable, results supported the theory of combined compensation-correspondence for those with insecure attachments to caregivers. Individuals with insecure attachment to caregivers were more likely to compensate for their insecure attachment bonds through participation in religious activity, whereas their internal, private relationship with God corresponded with their previous insecure attachment bonds. Individuals with insecure attachment to caregivers were more likely to endorse symptoms of depression and report introjective, but not anaclitic, depressive experiences. With respect to attachment to God, introjective depressive experiences were positively related to both anxious and avoidant attachments, whereas, anaclitic depressive experiences were positively related only to anxious attachment to God. Anxious attachment to God was found to partially mediate the relationship between insecure attachment to caregivers and depression symptoms. Finally, attachment effects were similar across gender, ethnicity, and age, with some notable exceptions.
Interpersonal Decentering and Psychopathology in a University Clinic Sample
This study examined the relationship between interpersonal decentering and symptoms of psychopathology among 48 clients from the Psychology Clinic at the University of North Texas. The Thematic Apperception Test (TAT) and the Symptom Checklist 90-Revised (SCL-90-R®) instrument were administered to clients along with demographic packets. Interpersonal decentering was assessed using Melvin Feffer's Interpersonal Decentering Scoring System for the TAT. It was hypothesized that higher scores of global symptom severity would be associated with lower scores of interpersonal decentering. Higher scores of paranoid ideation, psychoticism, and hostility were also hypothesized to be associated with lower scores of interpersonal decentering. Results did not support these hypotheses. However, exploratory analyses revealed a significant correlation between higher scores of phobic anxiety and lower scores of interpersonal decentering. Results also provided information regarding the three methods for calculating interpersonal decentering summary scores.
An item response theory analysis of the Rey Osterrieth Complex Figure Task.
The Rey-Osterrieth Complex Figure Task (ROCFT) has been a standard in neuropsychological assessment for six decades. Many researchers have contributed administration procedures, additional scoring systems and normative data to improve its utility. Despite the abundance of research, the original 36-point scoring system still reigns among clinicians despite documented problems with ceiling and floor effects and poor discrimination between levels of impairment. This study is an attempt to provide a new method based upon item response theory that will allow clinicians to better describe the impairment levels of their patients. Through estimation of item characteristic curves, underlying traits can be estimated while taking into account varying levels of difficulty and discrimination within the set of individual items. The ultimate goal of the current research is identification of a subset of ROCFT items that can be examined in addition to total scores to provide an extra level of information for clinicians, particularly when they are faced with a need to discriminate severely and mildly impaired patients.
Late adolescents' parental, peer, and romantic attachments as they relate to affect regulation and risky behaviors.
The current study examined the relationships among attachment styles to parent, peer, and romantic partner, ability to regulate emotion, as well as engagement in sexual behaviors and substance use. Attachment theory and previous research suggests that an individual learns how to manage emotions through the modeling of appropriate techniques and a stable sense of self-worth. These two aspects develop through a secure attachment bond with an important figure. When an individual does not have a secure attachment bond in which to practice adaptive affect regulation strategies, he/she may attempt to manage emotions through external means, such as sexual behaviors or substance use. Overall, results supported these associations, with some notable exceptions. Across attachment sources a secure attachment style was related to lower levels of psychological distress and less engagement in substance use. In contrast to the findings from earlier studies, affect regulation did not mediate the relationship between attachment and substance use, and engagement in sexual behaviors was not significantly related to either attachment style or affect regulation.
Longitudinal Study of Loneliness and Depression as Predictors of Health in Mid- to Later Life
The longitudinal relationship between loneliness and depression as predictors of chronic health conditions in middle-aged to older adults was investigated utilizing data collected by the Health and Retirement Study (HRS), a national representative longitudinal study of health, retirement, and aging, conducted by the Institute for Social Research (ISR) Survey Research Center (SRC) at the University of Michigan, funded by the National Institute on Aging and the Social Security Administration. The correlation between these loneliness and depression was moderate (r = .32 to r = 51). The single-item subjective self-report of loneliness was found to be an adequate measure of loneliness. A cross-lagged panel correlation and regression design was used to examine the longitudinal relationship between loneliness, depression, and chronic health conditions. A temporal precedence was indicated implying a causal relationship with depression leading to subsequent loneliness. The relationship between recurring loneliness and chronic health conditions was weak (r = .13).
Negative affect, introversion and physiological markers of cardiovascular disease.
Cardiovascular risk factors have expanded to include personality and other psychological characteristics. Negative affect (NA) has a longstanding history in cardiovascular health, but the path by which NA leads to cardiovascular disease (CVD) is yet to be defined. The following study examined the relationship of high NA and low extroversion (EX) with physiological cardiovascular markers in a sample of non-medical, professional adults. Our results indicated that individuals high in NA and low in EX displayed a significantly lower platelet count and a significantly higher mean platelet volume. Individuals high in NA displayed a significantly lower cholesterol risk ratio, while individuals high in EX displayed significantly higher platelet counts. Personality was not significantly related to blood pressure, high or low density lipoproteins. Understanding the relationships among psychological variables and physiological markers will help clinical researchers design interventions that reduce the likelihood of CVD.
Neurocognitive implications of diabetes on dementia as measured by an extensive neuropsychological battery.
Diabetes is a disease with a deleterious pathology that currently impacts 4.5 million individuals within the United States. This study examined the ability of a specific neuropsychological battery to identify and classify dementia type, investigated the impact of diabetes on cognition and analyzed the ability of the memory measures of the 7 Minute Screen (7MS) and the Rey-Osterrieth Recall to correctly categorize dementia type when not used in combination with a full battery. The battery in addition to exhaustive patient history, medical chart review and pertinent tests were used in initial diagnosis. Results indicated the battery was sufficient in the identification and classification of dementia type. Within the sample, diabetes did not appear to significantly impact overall battery results whereby only two measures were minimally affected by diabetes. Finally, the memory measures of the 7MS and the Rey-Osterrieth Recall were sufficient to predict membership into the Alzheimer's (AD) and vascular dementia (VD) groups with 86.4% accuracy. The classification percentage dropped to 68.3% with addition of the mild cognitive impairment category. The full battery correctly classified AD and VD dementia 87.5% and appeared to be the most robust.
Neurocognitive Variables Underlying Group Performance on a Measure of Effort: The Medical Symptom Validity Test (MSVT)
This study utilized the Medical Symptom Validity Test (MSVT) and a set of standard neuropsychological instruments to determine the underlying construct of the MSVT that accounts for effort in mild traumatic brain injury (mTBI) patients by comparing/contrasting mTBI with dementia and an analog simulation. The results indicate that a common underlying neurocognitive construct (memory) exists between mTBI and dementia patients, which may account for poor effort as measured by the MSVT. Other underlying factors emerged for both groups, though they did not point to a common construct. This finding suggests that the overall effect of brain injury in neurologically impaired groups also impacts effort performance as measured by the MSVT. Similarly impaired performance patterns also emerged between mTBI and dementia groups in sub-groups that failed effort measures. Thus, failed effort tests may be a function of more pronounced deficits in these groups, rather than a function of effort. Finally, although similar effort profiles were noted between mTBI and analog simulators, the analog group was unable to mimic the neurocognitive effects of mTBI.
Neuropsychologic correlates of a normal EEG variant: The mu rhythm.
Although the mu rhythm is traditionally defined as a normal EEG variant, recent evidence suggests that mu may have functional significance in a variety of disorders such as autism, Parkinson's disease, and multiple sclerosis. While an increasing number of articles have focused on the blocking mechanism of mu in relation to various cognitive processes and disorders, few have examined the significance of a prominent mu rhythm in the background EEG. A few studies have examined the relationship between the mu rhythm and psychological disturbance, such as attentional and affective disorders. Increasing evidence suggests that EEG and qEEG variables may be useful in classifying psychiatric disorders, presenting a neurophysiological alternative to traditional symptom-based diagnosis and classification. Thus, the intention of the present study was to examine the relationship between neuropsychological variables, gathered from multiple assessment sources, and the presence of a prominent mu rhythm in the EEG. Results did not show a statistically significant difference between individuals with and without a prominent mu rhythm on the Test of Variables of Attention (TOVA); although individuals in the mu group showed a pattern of increased impulsivity and performance decrement over time. For adults, no significant differences were observed between groups on psychological variables measured by the Minnesota Multiphasic Personality Inventory-2 (MMPI-2). However, for children, the mu and control groups differed on several behavioral and emotional variables on the Child Behavior Checklist (CBCL). Results are examined in the context of other research and clinical implications are discussed.
Pediatric feeding disorders: Efficacy of multidisciplinary inpatient treatment of gastrostomy tube dependent children.
Efficacy of multidisciplinary inpatient treatment of feeding disordered children was sought through retrospective chart review of 40 G-tube dependent children ages 22 months to 7 years. Premature births were 55% of the sample ranging from 23 to 36 weeks gestation. The majority of co-occurring medical conditions included congenital anomalies (50%), gastroesophageal reflux disease (25%) and chronic lung disease (25%). Treatment effect analyzed from pre and post treatment measures of oral and G-tube caloric intakes resulted in a significant difference from admission to discharge for both oral intake, t (39) = 5.76, p < 0.001, d = 1.02, and G-tube dependency, t(39) = 10.94, p < 0.001, d = 2.03 with both showing strong treatment effects. Results indicated a highly reliable and valid method of treating severe pediatric feeding disorders.
Penile plethysmography: Validation with a juvenile sex offending population.
Traditionally, juvenile sex offenders have been ignored in the literature. More recently the research has expanded particularly in the area of assessment and treatment. This study focused on the assessment of sexual arousal to deviant stimuli using the penile plethysmography (PPG) since it likely plays a significant role in juvenile sex offending behaviors. The goal of this study assessed its validity and reliability using Becker et al.'s set of PPG scenarios with a population of juvenile sex offenders. Significant differences were found between groups of (a) admitters versus partial admitters and (b) offenders with and without male victims. This study also examined the latent structure of the PPG results and found three dimensions: arousal to male stimuli, arousal to females and paraphilias, and arousal to non-sexual acts. These findings provide important implications for assessment of juvenile sex offenders and add to the clinical utility of PPG assessments.
Personality and the prediction of outcome following rehabilitation in persons with acquired brain injuries: The Millon Behavioral Medicine Diagnostic (MBMD).
Neuropsychological rehabilitation following acquired brain injury is increasingly recognized as essential with the advancements in research evidence of its effectiveness, particularly as current estimates of disability following the most common forms of brain injury (traumatic brain injury and cerebrovascular accident) are so high. Improvements in predictive capabilities of researchers and clinicians are paramount in designing effective interventions. As many variables associated with outcome following brain injury are not controllable (e.g. severity of the injury, age, education), it is essential that rehabilitation programs design interventions to target those variables that are susceptible to amelioration. While personality factors have been shown to affect outcome in other medical illnesses, only a few studies have examined the influence of personality on outcome following neurorehabilitation for acquired brain injury. The results of these studies have been mixed. This study used the Millon Behavioral Medicine Diagnostic (MBMD) to predict outcome as measured by the Mayo-Portland Adaptability Index (MPAI-4) following brain injury rehabilitation in a heterogeneous sample of persons with acquired brain injuries (N = 50). It was hypothesized that specific coping styles scales from the MBMD (Introversive, Dejected, Oppositional), which are based on Millon's personality system, would predict outcome. Results indicated that both the Introversive and Oppositional coping styles scales accounted for significant amounts of variance in outcome beyond that accounted for by the severity of the injury alone (p < .001). In both cases, individuals with mild/moderate-moderate/severe limitations following completion of the rehabilitation program had significantly higher scores on the Introversive and Oppositional coping compared to individuals with more successful outcomes. The hypothesis that a dejected coping style would predict outcome was not supported. Implications for rehabilitation are discussed in the context of Millon's personality system.
Psychological characteristics contributing to performance on neuropsychological tests and effort testing.
The issue of effortful patient performance has been an area of clinical interest in individuals with minor traumatic brain injury (mTBI). Clinical attention to this area has increased largely because of an increase in the number of worker's compensation claims, injury-related lawsuits and/or insanity defense pleas. As patients are presented with the opportunity for secondary gain, the issue of optimum performance on neuropsychological measures becomes salient. In addition to neurocognitive deficits, there are psychological characteristics associated with mTBI including depression, emotional disturbance, personality changes, and other psychopathology. This study utilized the MSVT, a set of standard neuropsychological instruments, and the Minnesota Multiphasic Inventory-2 (MMPI-2) to investigate the relationships between effort, psychological characteristics, and neuropsychological functioning in individuals with minor traumatic brain injuries. The first objective of this study was to determine which psychological factors were related to effort in mTBI. The second objective was to determine if there were differences between groups that performed poorly on effort testing and groups that performed adequately on effort testing, based on relevant psychological characteristics. The results of the analyses supported the first hypothesis. Hysteria was inversely related to effort, and Mania was positively related to effort on one of five measures of effort. The second hypothesis was not supported.
Readiness for change as a predictor of treatment effectiveness: An application of the transtheoretical model.
Clinical research suggests that adolescent offenders often do not view their criminal behaviors as problematic and, therefore, are not motivated for treatment. Although customarily defined as a static characteristic, the transtheoretical model (TTM) proposes treatment amenability is dynamic and can be achieved through tailored interventions that motivate individuals for treatment. The current study examines the predictive validity of TTM measures for adolescent offenders at a maximum security correctional facility. In particular, the Stages of Change Scale (SOCS) and Decisional Balance for Adolescent Offenders (DBS-AO) were compared with a more traditional assessment tool utilized in evaluating treatment amenability of juvenile offenders (i.e., Risk-Sophistication-Treatment Inventory; RSTI). One hundred adolescent offenders from the Gainesville State School completed two waves of data collection with a 3-month time interval. Information was collected on offenders' treatment progress between waves. Consistent with TTM research, predictors of treatment progress included low scores on the Cons scale on the DBS-AO and on the Precontemplation scale on the SOCS. Participants in the most advanced levels of treatment also scored high on the Sophistication-Maturity scale on the RSTI and the Impression Management scale on the Paulhus Deception Scale.
Reducing the risk of disordered eating among female college students: A test of alternative interventions.
The purpose of this study was to test the effectiveness of a cognitive-dissonance based intervention in reducing disordered eating attitudes and behaviors. The intervention program created dissonance through discussion, exercises, and homework aimed at addressing and countering internalized sociocultural pressures, beliefs and values about women's bodies, attractiveness, and worth in the U.S. Seventy-seven female undergraduates were randomly assigned to one of four conditions: cognitive-dissonance, combined cognitive-dissonance, healthy weight placebo control, and wait-list control To determine effectiveness of the intervention, MANCOVA procedures were used, with Time 1 scores serving as the covariate. Overall, the women who received the dissonance based interventions produced the strongest effects among measures assessing sociocultural pressures, internalization, and body dissatisfaction in comparison to the control group, and experienced significant reductions in dieting behaviors and bulimic symptoms over the course of the study, suggesting that the creation of dissonance via the intervention assisted the women in reducing eating disorder risk factors.
The relationship between interpersonal dependency and therapeutic alliance: Perspectives of clients and therapists.
Both interpersonal dependency and the importance of the therapeutic alliance to successful psychotherapy outcomes have been widely studied. However, these two areas of study rarely have been viewed conjointly despite the reportedly large number of clients with dependency who present for treatment. This study elucidated the relationship between interpersonal dependency and the therapeutic alliance. Additional hypotheses explored client-therapist agreement on alliance strength in relation to client interpersonal dependency. Participants were graduate student therapists (N = 26) and their individual psychotherapy clients (N = 40) in a training clinic at a large, southwestern university. Within their first three sessions of psychotherapy, participating clients told nine Thematic Apperception Test stories and completed structured self-report measures of adult attachment, social desirability, and psychological symptoms. Interpersonal dependency was scored from the TAT stories, using the TAT Oral Dependency (TOD) scoring system developed by Masling, Rabie, and Blondheim (1967) and Huprich (2008). Three sessions following initial data collection, participating clients and their therapists completed structured self-report measures of the therapeutic alliance. Analyses revealed that interpersonal dependency was not significantly associated with client and therapist alliance ratings or the congruence between client and therapist alliance ratings. However, specific scoring categories of the TOD were associated with client alliance scores in opposing directions. In contrast to hypotheses, self-reported attachment-related dependency was significantly related to client alliance ratings and to the congruence between therapist and client alliance ratings. Clients with higher levels of self-reported attachment-related dependency rated the alliance less favorably, in agreement with their therapists, than did clients with lower levels of attachment-related dependency. Additional analyses were unsuccessful in replicating findings from previous research on interpersonal dependency. The clinical and research implications of these findings are discussed.
Self-inflicted and other-inflicted intentional burns versus unintentional burns: A comparison study.
Burn injuries are associated with significant mortality and morbidity. Intentional burn injuries are not well understood, and warrant study to improve adjustment and outcomes. The present study examined group differences between intentional and unintentional burn injuries, comparing individuals with self-inflicted (SIB; n=109) and other-inflicted (OIB; n=109) burns to an unintentional burn (UB) group. Compared to UB, those with intentional (SIB, OIB) burn injuries were more likely to be young, female, unmarried, unemployed, abuse substances, and have positive alcohol/drug screens at hospital admission. Individuals with intentional burns report more psychological distress, lower quality of life in some areas, and lower life satisfaction. When SIB and OIB were examined individually, OIB were more likely to be African American compared to SIB and UB. OIB also had more anxiety and paranoia than UB. SIB was more likely than OIB and UB to have had medical problems or psychiatric disorders and treatment prior to the burn injury. Those with SIB were 3 times more likely than UB to die in the hospital even after controlling for age, severity of burn, and inhalation injuries. Moreover, the SIB group had high rates of suicidal ideation at discharge and follow-up. Treatment implications for burn treatment providers were discussed.
Stories: A Revision of the Willingness & Action Measure for Children and Adolescents (WAM-C/A)
In its earliest stages, acceptance and commitment therapy (ACT; Hayes, Strosahl, & Wilson, 1999) with youths appears to be a promising therapeutic approach. Experiential willingness and committed action are two foci of ACT, making their assessment an integral part of therapy. Field tests have found validity problems with the Willingness and Action Measure for Children and Adolescents (WAM-C/A). The current study utilized the Story Version of the Willingness and Action Measure for Children and Adolescents (SWAM-C/A). Results supported the relationship between the SWAM-C/A and measures of experiential avoidance and mindfulness. Factor analysis indicated the presence of several distinct willingness and action factors. These results support the need for continued work on measurement of willingness and action in youth.
Targeting dimensions of psychopathy in at-risk youth: Assessment and utility of a focused cognitive behavioral therapy program.
Individuals presenting with high levels of psychopathy demonstrate chronic and severe antisocial behavior and poor treatment outcomes in response to generalized rehabilitative programs. Recent research has examined the relationship between delinquency in child/adolescent populations and subsequent psychopathy. Focusing on community based/referred population of at-risk youth, this study developed and examined the effectiveness of an 18-session, psychopathy-focused, group CBT treatment program. The study incorporated treatment (n = 34) and usual-care comparison (n = 30) groups and a brief follow up period. Treatment outcomes examined measures of psychopathy, anger, impulsivity, motivation for treatment, self-reported problems, and indices of behavior. The treatment program demonstrated reductions in psychopathy on the Interpersonal (d = .55) and Affective facets (d = .24) of the PCL:YV. It also reduced overall impulsivity and improved anger suppression and treatment motivation, particularly among youth presenting with higher levels (relative to this study) of psychopathy. As a result of treatment, decreased incidents with the juvenile justice system were also observed, both during the treatment period and at six weeks follow-up. This study provides an initial empirical foundation for the ongoing development of targeted interventions for youth demonstrating psychopathic traits.
Team-based support systems: Generating a testable support systems model and accompanying hypotheses.
Scant research exists to illuminates the nature of organizational efforts, or support systems, designed to provide work teams with what is needed to be successful. The sample (N = 20) consists of experienced researchers and practitioners discussing work team implementations and the ongoing support needed for sustainability. The following seventeen team-based support systems were examined: (a) rewards and recognition, (b) team goal setting, (c) performance measurement, (d) performance appraisal, (e) team placement and structure, (f) communication and information systems, (g) culture, (h) training, (i) knowledge management, (j) business strategy, (k) leadership, (l) between teams integration, (m) resource distribution, (n) physical workspace, (o) program evaluation and renewal, (p) personnel selection system, and (q) work process design. This study uses a grounded theory approach to build a support system model and provide hypotheses for future research.
Traumatic Brain Injury in Children and Adolescents: An Evaluation of the WISC-III Four Factor Model and Individual Cluster Profiles
Traumatic brain injury (TBI) is the leading cause of death and disability among children and adolescents in the US. Children and adolescents who sustain moderate and severe head injuries are much more likely to evidence significant deficits in neuropsychological functioning when compared with children with mild head injuries. Information about the recovery process and functional sequelae associated with moderate and severe head injuries remains limited, despite clear indications that children who experience such injuries typically exhibit notable deficits in intellectual functioning, particularly during the acute phase of recovery. Thus, the present study was conducted to augment research on intellectual functioning in children with moderate or severe head injuries. To accomplish this, the study first examined the proposed factor model of the WISC-III in children with moderate and severe TBI. Given high prevalence rates and similar trends in cognitive impairment, particularly within the frontal lobe structures (e.g., disrupted cognitive flexibility and divided attention), the study also examined this same factor model for a group of children with attention-deficit/hyperactivity disorder (ADHD) and compared it with the model fit from the TBI group. In the second phase of the study, both the TBI and AHDH groups were evaluated to determine if distinct WISC-III index score cluster profiles could be identified. Lastly, the cluster groups for both the TBI and ADHD samples were validated using important demographic and clinical variables, as well as scores from independent neuropsychological measures of attention, executive functioning, and working memory. Parent reports of psychological and behavioral functioning were also used in an attempt to further distinguish the cluster groups. Study limitations and future research implications were also discussed.
Women's career success: The contributions of human capital, individual, organizational, and power variables.
Women are a significant presence in today's workforce; however, few rise to the top management ranks. Therefore, there is a critical need to better understand the factors that facilitate their success. This study examined several variables that may contribute to women's objective (income, span of control, promotions) and subjective (self-reported satisfaction) success. Predictive variables include human capital (training, experience), individual (perception of promotability, motivation for training), organizational (supervisor gender, percentage of male subordinates) and power (extent of supervisory authority) factors. Participants were members of the National Longitudinal Surveys Young Women cohort, conducted by the Bureau of Labor Statistics. Data were analyzed through simultaneous multiple regression analysis, and the results indicated that education was significantly related to income for all women. For women in management positions, their degree of supervisory power was also predictive of higher income, yet negatively associated with job satisfaction. Further, their span of control was positively influenced by the amount of time they spent in on-the-job training. The implications for women's career advancement, study limitations, and future research possibilities are also discussed.
Women's erotic rape fantasies.
This study evaluated the rape fantasies of a female undergraduate sample (N = 355) using a sexual fantasy checklist, a sexual fantasy log, a rape fantasy scenario presentation, and measures of personality. Results indicated that 62% of women have had a rape fantasy. For these women, the median rape fantasy frequency was about four times per year, with 14% of participants reporting that they had rape fantasies at least once a week. Further, rape fantasies exist on a continuum between erotic and aversive, with 9% completely aversive, 45% completely erotic, and 46% both erotic and aversive. Women who are more erotophilic, open to fantasy, and higher in self-esteem tended to have more frequent and erotic rape fantasies than other women. The major theories that have been proposed to explain why women have rape fantasies were tested. Results indicated that sexual blame avoidance and ovulation theories were not supported. Openness to sexuality, sexual desirability, and sympathetic activation theories received partial support.
