Allergen Research and Its Implications for Psychology: History, Current Status, and Prospectus

Description: The purpose of this manuscript was to present a brief history, the current status, and a prospectus of allergen and allergic reactions. Research on allergic reactions, particularly as viewed from the psychogenic position, was presented. The review strongly suggests that the psychogenic orientation has been frought with contradictions, unnecessarily complex interpretations, and an over-abundance of subjective, dynamic, and analytic redundancies which have done little more than perpetuate the stagnation of a rather important subdomain of the "mental" health professions.

Altruism and Depression: Exploring This Relationship and the Mechanisms Behind It

Description: The impact of environmental influences on depression has been well established by research. In particular, it is known that receiving/perceiving adequate social support has a protective influence on depression. Less is known about the protective benefits of providing support to others, namely in the form of altruistic, empathetic, or prosocial behavior. While research has shown that having altruistic attitudes and engaging in altruistic behaviors has a positive impact on physical health and mental well-being, studies on the association between altruistic attitudes and/or behavior and depression are limited. The present study examined the relationship between altruism and depression, and hypotheses were tested that allow for explanation of why altruism may protect against depression. A sample of 303 participants was recruited from the University of North Texas and the surrounding community. Participants completed an online survey that examined their altruistic activities, details regarding these activities, their prosocial attitudes, and their current level of depression. Results did not support that level of involvement in altruistic activities is directly related to depression severity. However, outcomes from involvement in altruistic activities, including sense of overburden from participating in altruistic activities, level of social interaction with other helpers and those helped during altruistic activities, and sense of life satisfaction and purpose gained from participating in altruistic activities, were significantly related to depression severity. These results suggest that participating in altruistic activities that are not perceived as overburdening may lead to outcomes that could positively impact depression. Limitations and directions for future research are discussed.

Alzheimer's Disease and Attention: An Investigation into the Initial Stage of Information Processing

Description: This study explores the possibility that attentional deficits are an early clinical symptom of Alzheimer's disease. The three goals are to demonstrate that individuals with Alzheimer's disease are impaired on tasks of attentional processing, to compare the sensitivity of currently used measures of attention to attentional dysfunction, and to compare the behavioral response styles (errors of commission) of Alzheimer's disease subjects and non-impaired subjects. The subjects were 22 males and 46 females with a mean age of 70.76 years. Thirty-six had the presumptive diagnosis of Alzheimer's disease; 18 were identified as mildly impaired and 18 as moderately impaired on the Cognitive Capacity Screening Examination. The remaining 32 subjects comprised the non-impaired control group. Five measures of attention were administered to all participants: the Digit Span Subtest of the WAIS-R, the Seashore Rhythm Test of the Halstead-Reitan Neuropsychological Battery, the Vigilance and Distractibility tasks of the Gordon Diagnostic System, and the Concentration/Interference task. The results show a significant difference in attentional processing between normal (non-impaired) subjects and subjects diagnosed with Alzheimer's disease. All measures of attention used in this study, except the Concentration/Interference task, differentiated normal subjects from moderately impaired Alzheimer's disease subjects. The Digit Span Subtest and the Seashore Rhythm Test were unable to differentiate between normals and mildly impaired Alzheimer's disease subjects or between mildly and moderately impaired Alzheimer's disease subjects. The Gordon Diagnostic System was able to distinguish normals form mildly impaired Alzheimer's disease subjects and mildly from moderately impaired Alzheimer's disease subjects. On the Gordon Diagnostic System the Alzheimer's disease subjects made significantly more errors of commission than did the normal subjects. This investigation concludes that attentional processing dysfunction occurs in the dementing process associated with Alzheimer's disease. The findings suggest that the Gordon Diagnostic System is a more sensitive technique for assessing attentional dysfunction than the ...

Ambiguity of Loss, Anticipatory Grief, and Boundary Ambiguity in Caregiver Spouses and Parents

Description: The purpose of the present cross-sectional study was to examine the effects of ambiguity of loss and type of caregiver-to-patient relationship on anticipatory grief, negative physical and psychological outcomes associated with grief, and boundary ambiguity in family caregivers of chronically ill patients. Questionnaires were completed by 23 parents of ill children and 30 spouses of ill mates. Using an original and a revised concept for level of ambiguity, partial support was found for the prediction that parents and spouses in high ambiguity of loss circumstances would report more anticipatory grief than those in low ambiguity ones. Contrary to prediction, a slight but nonsignificant trend occurred for parents and spouses in low ambiguity situations to report more negative physical and psychological effects associated with grief as well. Level of ambiguity was not found to impact boundary ambiguity as had been hypothesized. Spouses reported more boundary ambiguity than parents, regardless of level of ambiguity of the loss. Contrary to prediction that parents would report less anticipatory grief and more negative physical and psychological outcomes than spouses, generally, no significant differences were found between the two groups. However, using the original concept of ambiguity, parents did tend to recall more past grief than spouses. The study highlighted several methodological concerns which impact research on loss and grief, particularly the difficulty involved in recruiting participants with subsequent occurrence of sampling bias, rudimentary status of available measurement tools, and a host of potentially confounding personal and sociodemographic variables. The present study supports a view of the loss which occurs in families dealing with chronic illness as a complex process whose impact on grief, distress, and family upheaval is influenced by multiple factors. Such factors include both the ambiguity of the loss and the type of family relationship involved. Complex research of a longitudinal nature using ...

Analysis and Comparison of a Developmental Task Scale on Differing Adolescent Populations

Description: The following research questions were investigated: (a) Can the age-mates scales from the Dales developmental task scales be used with southwestern-urban adolescent populations? (b) Are there any systematic differences between northeastern-nonurban and southwestern-urban subject populations on the response to these scales? The subjects consisted of 884 adolescents, 11 through 15 years, evenly divided by sex. Subject responses were analyzed by sex and age groups using Guttman scalogram analysis. Goodman's test of significance revealed that the results could have occurred by chance (p > .05). The instrument in its present form was not found useful'-for an urban population. Lack of reproducibility made comparison of the performance of urban and nonurban adolescents unjustified.

An Analysis of Test Scores Between Language- and/or Learning-Disabled and Minimally Brain-Injured Special Education Students

Description: The purpose of this study was to determine significant differences in test scores between LLD and MBI Special Education students. The records of thirty-seven LLD and fifty-six MBI students between the ages of six through eleven were obtained from a small Texas school district. The results indicated no significant differences between groups on WISC Full Scale, Performance and Verbal scales or on WISC subtests scores. No significant differences were found on WRAT scores. Significant differences were found on the Bender-Gestalt Test for Children and the Visual Aural Digit Span Test at the nine- through eleven-year level. No differences were found at the six- through eight-year level.

An Analysis of the Performance of a Clinical Sample of African American, Caucasian, and Hispanic Children on the WISC-III

Description: The goals of revision for the Wechsler Intelligence Scale for Children-Third Edition included enhancement of the factor structure, improvement of subtests, and revision of norms. The researchers reported that the very few items that were found to be biased were replaced. The WISC-III performance of a clinical sample of African American, Caucasian, and Hispanic children was analyzed to determine if the test bias was eliminated as claimed in the goals of the revision.

Androgyny and Sex-Role Measurement: A Personal Construct Approach

Description: Recent research into sex roles has been heavily influenced by androgyny theory, and by the development of the Bern Sex-Role Inventory (BSRI; Bern, 1974). Psychological androgyny is the combination, in one individual, of both culturally defined masculine and feminine personality traits. The Sex-Rep, a new instrument for assessing sex role which is aimed at rectifying certain problems associated with the BSRI, was then described. The Sex-Rep, the BSRI (Bern, 19 34), the Texas Social Behavior Inventory (TSBI; Spence & Stapp, 1974), the Beck Depression Inventory (BDI, Beck, 1967), and a self-concept thermometer, were given to 100 male and 108 female undergraduates. Results indicated that the BSRI and the Sex-Rep are both valid sex-role instruments, insofar as they both discriminate between males and females. They tend to measure nonredundant components of sex role as indicated by a lack of overlap between their sex-role classifications. The present study did not find any support for the balance model of androgyny which suggests that high masculinity and high femininity interact by balancing each other to produce a healthier, more behaviorally flexible individual. BSRI masculinity (M) was strongly related to adjustment in both sexes, but BSRI femininity (F) had little impact. This relationship between BSRI M and adjustment was described as probably resulting from measurement artifact since (&) only socially desirable traits are included on the BSRI, (b) removing self-esteem effects from the BSRI M scale enhanced its ability to discriminate between the sexes, (c) Sex-Rep masculinity was not related to adjustment for women, and its linkage to adjustment for men was less strong than BSRI M, (d) women rated their feminine constructs as more desirable than their masculine constructs, and (e) there were no actual self-esteem differences between males and females. Thus, findings from the BSRI regarding the relationship between sex role and adjustment ...

Anger and Hostility Measures: Effects of Social Desirability

Description: Individuals responding in a socially desirable (SD) fashion, rather than in a manner that reflects their true behavior, has been a problem for self-report questionnaires since their inception. The purpose of this study was to examine the hypothesis that the probability an item is endorsed on a self-report measure of anger is directly proportional to the rated SD of that item. Eighty-two subjects completed the Buss-Durkee Hostility Inventory (BDHI), the Profile of Moods State (POMS), and the State- Trait Anger Expression Inventory (STAXI). A probability of endorsement was computed for each of the measures' items. Twenty additional subjects rated the measures' items for SD. Each item's SD rating was paired with the probability the item was endorsed to produce a correlation coefficient for each measure. Results strongly support the stated hypothesis. Directions for future research are discussed.

Anger, Forgiveness and Mindfulness: Correlates of Perceived Stress in an LGB Sample

Description: A sexual minority is someone who identifies as lesbian, gay or bisexual (LGB). According to the Minority Stress Model (Meyer, 2003), sexual minorities encounter significant levels of stress due to their minority group status, thus they are more likely to experience perceived stress. Our cross-sectional, correlational study aimed to explore the relationships between forgiveness, mindfulness and anger and how they are related to perceived stress in a convenience sample of ethnically diverse LGB adults. We hypothesized that: 1) anger is positively associated with perceived stress; 2) forgiveness is negatively associated with perceived stress; 3) mindfulness is negatively associated with perceived stress; and 4) anger, forgiveness and mindfulness account for a significant proportion of the variance in perceived stress. 5) The relationship between anger and perceived stress is moderated by forgiveness. 6) The relationship between anger and perceived stress is moderated by mindfulness. Among LGB adults, the extant literature does not address these four variables in conjunction and the relationships between anger, forgiveness, mindfulness and stress has yet to be explored. Various statistical analyses were conducted, including a hierarchical linear regression to test our model. We found that our overall model accounted for 36% of the total variance in perceived stress (F(5, 142) = 17.31, p <.01) with anger (β = .31, t = 3.55, p = .001) and forgiveness (β = -.21, t = -2.56, p < .05) as the significant predictors. Contrary to prediction, forgiveness and mindfulness did not moderate the relationship between anger and perceived stress in our LGB sample. Limitations, strengths, future research and implications are discussed.

Anger/Hostility: Reliability of Measurement and Correlates of Health History

Description: The purpose of this study was to (1) assess the reliability and validity of anger/hostility measures, (2) examine the relationship between anger/hostility and other negative emotions, and (3) examine the relationship between anger/hostility and health history. Sixty-five subjects were given the Buss Durkee Hostility Inventory (BDHI), the State-Trait Anger Expression Inventory (STAXI), the Profile of Mood States pomsS), the Clinical Analysis Questionnaire (CAQ), the State-Trait Anxiety Inventory (STAI), the Health and Wellness Attitude Inventory (HWAI), and a health questionnaire designed to provide information about past disease and alcohol/drug use. Overall, the BDHI and POMS displayed good test-retest reliability. All six of the global indices of anger/hostility intercorrelated at a significant level, thus demonstrating good concurrent validity. The six global measures of anger/hostility also correlated at a significant level with other negative emotions.

Anger Reduction in Closed Head Injured Individuals with Group Social Skills Training

Description: In the present study, an anger management treatment program was compared to a pseudo-social skills training program (self-help group) and waiting list control group to determine its effectiveness in reducing irritable/angry behavior in head injured subjects. Subjects consisted of 28 adults with previous head injury trauma who had difficulty with excessive irritability and anger. Subjects averaged 35.4 years of age and had an average of 8.9 years post head injury. Treatment consisted of 10 group sessions over a five week period. Anger management training was designed to teach subjects self management skills aimed at reducing the frequency of angry acting out behavior. Training methods included role playing, relaxation training, assertiveness training and cognitive restructuring. The pseudo-social skills training group was a self-help group designed to encourage discussion of irritability problems without teaching specific coping techniques. To assure some degree of homogeneity in cognitive abilities among subjects, minimum eligibility scores were required on five subtests of the Wechsler Adult Intelligence Scale - Revised and the Peabody Picture Vocabulary Test. Dependent measures were pre and posttreatment scores obtained from five categories of the Katz Adjustment Scale - Relative form: belligerence, negativity, general psychopathology, social obstreperousness, and social role functioning. In addition, pre and posttreatment recordings of observed angry/irritable behavior in the subjects were obtained from a significant other. Results failed to reveal statistically significant differences on the dependent measures between the three study groups. In addition, analysis failed to reveal any significant variables that predicted outcome. It is evident that much more organized research is needed to further investigate the possibilities of treatment for various problems encountered by those with head injuries.

The Angoff Method and Rater Analysis: Enhancing Cutoff Score Reliability and Accuracy

Description: At times called a philosophy and other times called a process, cutting score methodology is an issue routinely encountered by Industrial/Organizational (I/0) psychologists. Published literature on cutting score methodology appears much more frequently in academic settings than it does in personnel settings where the potential for lawsuits typically occurs more often. With the passage of the 1991 Civil Rights Act, it is no longer legal to use within-group scoring. It has now become necessary for personnel psychologists to develop more acceptable selection methods that fall within established guidelines. Designating cutoff scores with the Angoff method appears to suit many requirements of personnel departments. Several procedures have evolved that suggest enhancing the accuracy and reliability of the Angoff method is possible. The current experiment investigated several such procedures, and found that rater accuracy methods significantly enhance cutoff score reliability and accuracy.

Antecedents of Commitment to and Support of a Proposed Change Initiative in a Southern Baptist Congregation.

Description: This study extends research findings directed at a micro-focus of change by assessing individual organizational members' perspectives and psychological constructs influencing change efforts by an organization. The change initiative in question regards the construction of a new facility and subsequent relocation to said facility. Moral commitment to the organization (negative), change initiative's fit with organizational vision, and social influence significantly contributed to variance in members' affective commitment to change. Trust in leadership and normative commitment to the organization (NCO) significantly contributed to variance in members' normative commitment to change. Continuance commitment to the organization and participation (negative) significantly contributed to variance in members' continuance commitment to change. NCO, change initiative's fit with organizational vision, and participation significantly contributed to variance in support of the proposed change initiative. Affective commitment to the organization (negative), NCO (negative), trust in leadership (negative), and disruption of influence significantly contributed to variance in members' intent to leave the organization.

Antecedents of the Psychological Adjustment of Children and Grandparent Caregivers in Grandparent-Headed Families

Description: Grandparent-headed families are diverse in nature and represent a rapidly growing family type. While challenges facing grandparent caregivers are well documented, less is known about the well-being of their grandchildren, with many early studies relying on small samples of convenience. This study used an existing large national database, the National Survey of America's Families (NSAF), to compare differences in well-being of both children and grandparent caregivers across the independent variables of family type, ethnicity, gender, and age. Findings suggested better mental health and less parental aggravation for caregivers in traditional two parent intact families as compared to grandparents co-parenting in a multi-generation home, skipped generation grandparents (raising their grandchild with no parent present) or single parents. Skipped generation grandparents in particular reported most caregiver aggravation. Child physical health was reported to be worse by skipped generation grandparent caregivers. Behavior problems were reported to be worse for children in grandparent headed households than those in traditional families, particularly for teenagers raised in skipped generation households by their grandmothers. Specific results, limitations and future directions for research on grandparent-headed households were discussed.

Anticipating Work and Family: Experience, Conflict, and Planning in the Transition to Adulthood

Description: The purpose of this study was to examine the development of work and family plans in young adults, and to clarify the long-term stability, prevalence, and consequences of anticipated work-family conflict. The study utilizes Super’s model of career development and social cognitive career theory, as well as research on current work-family interface, as a framework for understanding the period of anticipating and planning for multiple role integration that occurs between adolescence and adulthood. A sample of 48 male and 52 female college students assessed two years prior completed self-report questionnaires measuring work, marriage, and parenting experience; anticipated work-family conflict; and multiple-role planning. Results of this study suggest that students desire both a career and a family, and recognize potential challenges of a multiple-role lifestyle. Such recognition of anticipated work-family conflict varies by conflict domains and measurement methods, but remains stable over two years. Results also suggest that anticipated work-family conflict does not mediate the relationship between experience and planning; instead, marriage experience predicts planning directly. Implications for the findings are discussed as are suggestions for directions of new research concerning anticipated work-family conflict and planning for multiple roles.

Anxiety and its Correlates: Introversion-Extroversion, Locus of Control, and Reinforcement Expectations

Description: The problem with which this study is concerned is that of considering the relationship between neurotic anxiety and several personality variables. Even though anxiety has been the subject of many studies, it is still poorly defined. The basic model to be considered is Eysenck's three-dimensional model between neuroticism and introversion-extroversion. This model is expanded to include Rotter's locus of control and reinforcement expectancy (optimism and pessimism).

Anxiety, Depression, and Sleep Disorders: Their Relationship and Reduction with Neurotherapy

Description: This study investigated the relationship among anxiety, depression, and sleep disturbances and the treatment of these three disorders through neurotherapy. Research suggests that these conditions commonly co-occur in the general population and that central nervous system (CNS) arousal may play a primary role in the development and maintenance of these disorders. Several recent studies suggested that neurotherapy, a biofeedback-based treatment for CNS dysregulation, might be an effective treatment for comorbid conditions, particularly the ones of interest here, depression, anxiety, and sleep disturbances. This investigation used a clinical case-series design to assess pre/post neurotherapy changes on objective measures of anxiety, depression, and sleep and to determine whether changes in anxiety and depression then predict improvements in sleep quality. Data for 23 participants (10 males) were obtained from files of adults (Mage = 40.22 years, SD = 16.20) who received at least 15 neurotherapy sessions (M = 47.83 sessions, SD = 22.23) the University of North Texas Neurotherapy Lab. Matched pair t-tests revealed that symptoms of sleep disturbance, depression, and anxiety showed significant improvements following neurotherapy. Neurotherapy treatment effect sizes generally ranged from moderate to large (d = .414 - .849). Multiple regression analysis found that changes in self-reported anxiety symptoms, but not depressive symptoms, predicted observed improvements in sleep quality (adjusted R2 = .26). Last, the implications and limitations were discussed in relation to neurotherapy practice and the associated research.
