Attention and Information Processing Variables in Hypothetically Psychosis-Prone College Students (open access)

Attention and Information Processing Variables in Hypothetically Psychosis-Prone College Students

Considering the explanations of schizophrenia that presume schizophrenia spectrum disorders (e.g., schizotypal personality disorder, schizoaffective disorder, etc.) to be genetically related to schizophrenia, the purpose of this study was to investigate the attention and information processing abilities of individuals who have been identified as schizotypal or psychosis-prone (i.e., schizophrenia spectrum functioning in individuals who do not have schizophrenia). Research indicates that persons identified as psychosis-prone may show attention and information processing deficits similar to individuals with schizophrenia. The identification and description of individuals who later decompensate into schizophrenia would advance the understanding of schizophrenia and its causes. The Chapman's PER-MAG scale (Perceptual Aberration-Magical Ideation) was used to identify 35 hypothetically psychosis-prone college students (schizotypy group) and 42 normal college students (nonschizotypy group) out of the 806 volunteer subjects. Their attention and information processing abilities were measured by COGLAB (a multiparadigmatic cognitive test battery that represents a continuum of cognitive functions, from preattentional to attentional, to conceptual). Their social adjustment was measured by the Premorbid Adjustment Scale (PAS). The hypotheses of the study were that the hypothetically psychosis-prone subjects would perform poorer than controls on COGLAB measures and that COGLAB measures of a more molar nature would better predict social adjustment …

Effects of Meal Size and Type, and Level of Physical Activity on Perceived Masculinity, Femininity, Likability and Attractiveness (open access)

Effects of Meal Size and Type, and Level of Physical Activity on Perceived Masculinity, Femininity, Likability and Attractiveness

Previous research indicates that women are judged on the amount of food eaten and that both men and women are judged on the type of food eaten. This study is an attempt to determine whether meal size or type predominantly accounts for these findings on the variables of masculinity, femininity, attractiveness, thinness, fitness, and likability. Physical activity was also included to determine its effect on these variable. Subjects used were 313 undergraduate students. Results indicate that meal type is more influential than meal size and that physical activity significantly influences judgements of others. The results are discussed in terms of future research and relatedness to socio-cultural theories of eating disorders.

Detection of Malingering on Raven's Standard Progressive Matrices and the Booklet Category Test (open access)

Detection of Malingering on Raven's Standard Progressive Matrices and the Booklet Category Test

The capacity of Raven's Standard Progressive Matrices (SPM) and the Booklet Category Test (BCT) to discriminate between groups of brain-injured, simulated malingering, and normal participants was investigated in this study. Exploratory analyses were also conducted to examine the differences between groups categorized as sophisticated and naive fakers. Clinical decision rules and discriminant function analyses were utilized to identify malingerers. Clinical decision rules ranged in hit rates from 41% to 78%, in sensitivity from 2% to 100%, and in specificity from 86% to 100%. Discriminant functions ranged in hit rates from 81% to 86%, in sensitivity from 68% to 73% and in specificity from 82% to 87%. Overall, the least helpful detection method examined was below chance responding on either measure, while the most efficient was gross errors for SPM.

Interpersonal Perception and Communication within Marital Dyads (open access)

Interpersonal Perception and Communication within Marital Dyads

The present study examined the relationships among similarity, interpersonal perception and communicative behaviors in marriage. It was hypothesized that greater understanding, feelings of being understood, and realization of understanding would be associated with greater self-disclosure, use of more direct person control strategies, and use of less attention control strategies. It was further hypothesized that measuring feelings of being understood and realization of understanding, in addition to measuring understanding, would improve prediction of behavior. Finally, it was hypothesized that the contextual measure of understanding would better predict self-disclosure and interpersonal control than would global measures of understanding.

Predictors of Compliance and Aggressive Behavior in the Presence of Command Hallucinations (open access)

Predictors of Compliance and Aggressive Behavior in the Presence of Command Hallucinations

The Schedule for Affective Disorders and Schizophrenia-Change Version (SADS-C), the Social Adjustment Scale-Patient Version II (SAS-PATII) and the Command Hallucination Questionnaire (CAQ) were administered to 86 psychotic inpatients to investigate the relationship between command hallucinations, aggressive behavior, and compliance. Two SADS-C items ("severity of hallucinations" and "depersonalization") were useful as indicators of command hallucinations. Ninety-two percent had complied with their command at least once in the past month. Three SADS-C variables related to compliance with command hallucinations were identified: middle insomnia, the belief that the voice was acting in your best interest, and overt irritability. The patients' level of distortion of reality did not appear to influence compliance rates. Results also indicated that patients who experience command hallucinations were not significantly more or less dangerous than other psychotic inpatients.

PTSD in Women following a Disaster: the Effects of Social Support and Gender Differences (open access)

PTSD in Women following a Disaster: the Effects of Social Support and Gender Differences

The purpose of this study was to examine and compare individuals that had survived a single incidence trauma, the Luby's massacre in Killeen, Texas. Participants answered questions regarding various facets of social support following the trauma, and were also screened for a diagnosis of PTSD. Participants' level of symptoms, specifically depression, anxiety, and phobic anxiety was measured over time with the SCL-90-R. The results of this study indicate that, while women initially experience a higher level of depression and phobic anxiety, there is no gender difference in rate of symptom change over time. This study also found that women were significantly higher than men on desirability, utilization and usefulness of social support. Of the target symptoms, however, only depression correlated with any facet of social support, specifically, desirability. Finally, this study questioned whether individuals would share more similarities with others based on gender or diagnosis. It is suggested by the current data that diagnosis is the better indicator of similarity.

Personality Correlates of Anorexia Nervosa in a Nonclinical Sample (open access)

Personality Correlates of Anorexia Nervosa in a Nonclinical Sample

The purpose of this study was to examine the relationship between anorexia nervosa and several personality traits. Past research in this area has been contradictory for several reasons. Sociocultural theories have described the media's role in promoting eating disorders by portraying a thin body-type as the ideal. However, they have neglected to describe the personality ideal which our society promotes in women. It is proposed here that anorexics incorporate and oppose this ideal. Therefore, the anorexic personality is one filled with conflict.

Racial Differences in Female Achievement Motivation and Motivation to Work (open access)

Racial Differences in Female Achievement Motivation and Motivation to Work

In the present project racial differences in female achievement motivation and motivation to work were examined, and related this information to the theory that African American females, when compared to White females, are less likely to marry someone equal to themselves in the areas of education, employment, and earning potential because of an assumed shortage of suitable African-American males. It was hypothesized that African-American females would score higher on assessments of achievement motivation and motivation to work, and rate lower the likelihood of meeting and marrying a partner equal in education level, employment level, and earning potential than would White females. Data analysis supported all hypotheses. The results were discussed in the context of the female achievement motivation literature as well as the literature concerning female motivation to work.

A Cross-Sectional Study of Custodial Grandparenting: Stresses, Coping Skills, and Relationships with Grandchildren (open access)

A Cross-Sectional Study of Custodial Grandparenting: Stresses, Coping Skills, and Relationships with Grandchildren

This cross-sectional study compared three groups of grandparents, two custodial and one noncustodial, to identify and delineate the unique challenges and expectations faced by custodial grandparents due to their nontraditional roles while attempting to disentangle grandparental role demands from child-specific problems as sources of distress. Those grandparents raising grandchildren demonstrating neurological, physical, emotional, or behavioral problems exhibited the most distress, the most disruption of roles, and the most deteriorated grandparent-grandchild relationships. Although the custodial grandparents raising apparently normal grandchildren demonstrated less distress, less disruption of roles, and less deterioration of the grandparent-grandchild relationship than those grandparents raising grandchildren displaying problems, they still demonstrated higher levels than did traditional grandparents. Those grandparents who reported fewer resources, demonstrated poor attitudes regarding seeking mental health services, and reported raising grandchildren displaying problems had the lowest levels of adjustment.

Anger and Hostility Measures: Effects of Social Desirability (open access)

Anger and Hostility Measures: Effects of Social Desirability

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.

Rorschach Assessment of Object Relations Development in Sexually Abused Children (open access)

Rorschach Assessment of Object Relations Development in Sexually Abused Children

Sexual abuse of children has profound negative effects on psychological development. This study examined the effects of sexual abuse on object relations functioning by using the Mutuality of Autonomy Scale (MAS, Urist, 1977) to score Rorschach protocols of 63 abused children and 60 non-abused clinical controls. The hypothesis that abused children would have less developed object relations than their non-abused counterparts was not supported. Neither was the hypothesis that children who experienced greater severity of sexual abuse would exhibit more malevolent object relations. The hypothesis that mean and modal MAS scores would be highly intercorrelated and interchangeable as research variables was supported. Comparisons of this sample to a normative sample are discussed.

Comparison of Visual and Auditory Continuous Performance Tests in Adults (open access)

Comparison of Visual and Auditory Continuous Performance Tests in Adults

Two continuous performance tests were administered to normal adult subjects. The mode of presentation (visual or auditory) and the type of task (vigilance or distractibility) were varied, and their effects on performance measured. Data were collected on eighty-two subjects, and results indicated that auditory presentation of stimuli increased the difficulty of both tasks. Results also suggest that the distractibility task administered in either mode was more difficult than the vigilance task. Intercorrelations among the four continuous performance tasks are provided. Normative data are presented on all four tasks administered. A measure of symptoms of attention-deficit disorder in adults, the Adult Behavior Checklist, was found to correlate significantly with another measure of pathology, the SCL-90-R.

Residual Cognitive Functioning of Elderly Males (open access)

Residual Cognitive Functioning of Elderly Males

The Aronson Cognitive Residual Evaluation Scale (ACRES), designed to assess residual cognitive functioning with potential loss due to age or CNS disorder, was examined with a male subject group. The five ACRES subtests were administered to 45 elderly males. Results were compared with a previously reported subject group of 48 elderly females. Measures of the subjects' levels of independent functioning and their performances on selected Wechsler Memory Scale Revised (WMS-R) subtests were related to ACRES scores. Intercorrelations among ACRES subtests suggest that more than one cognitive factor is assessed. WMS-R subtests showed moderately significant correlations with ACRES for verbal tasks and for nonverbal tasks. Findings were discussed within a framework of lateralization of CNS functions.

Perception of Punitive Childhood Experiences, Adult Coping Mechanisms and Psychological Distress

Differences in college student's psychological well-being, extrapunitiveness, and intropunitiveness were related to the presence or absence of maltreatment during childhood years, and its acknowledgement by the student. Subjects were 56 male and 85 female undergraduate students at the University of North Texas. Subjects were given structural scale v.3 of the California Psychological Inventory (CPI), the Extrapunitive (E), and Intropunitive (I) indices of the Hostility-Direction of Hostility Questionnaire (HDHQ), and the Physical Punishment scale (PP-scale) of the Assessing Environments Questionnaire (AEIII). Results indicate no significant differences in psychological well-being, extrapunitiveness, or intropunitiveness, which would be explained by the presence of maltreatment or its acknowledgement.

Post-Traumatic Symptomatology in the Luby's Shooting (open access)

Post-Traumatic Symptomatology in the Luby's Shooting

The role of exposure to a human-made disaster and the subsequent development of post-traumatic stress reactions were examined. Subjects included 49 males and 30 females who were variously exposed to the Luby's shooting incident in Killeen, Texas in October of 1991. Post-traumatic stress symptomatology was measured by the SCL-90R. Exposure was operationalized by using a scenario-rating scheme with independent raters estimating each subject's level of exposure. A regression and commonality analysis revealed that exposure is an important predictor in post-traumatic symptomatology. Premorbid functioning and gender were also found to play important roles, with females expressing higher levels of symptomatology.

Depression and Heart Rate Variability in Patients with Coronary Artery Disease (open access)

Depression and Heart Rate Variability in Patients with Coronary Artery Disease

Depression is an independent risk factor for morbidity and mortality in patients with coronary artery disease (CAD). Altered autonomic nervous system (ANS) activity, a common feature of depression, is also a risk factor for cardiac events in patients with CAD. Heart rate variability (HRV) reflects ANS activity, and reduced HRV predicts morbidity in cardiac populations. The purpose of this study was to determine whether differences in HRV exist between depressed and nondepressed patients with CAD. Twenty-one depressed inpatients, with angiographically documented CAD were retrospectively matched to 21 nondepressed CAD patients by sex, age, and smoking status. Demographic, medical, psychological interview data, and 24-hour ECG recordings were obtained. Depressed subjects had significantly lower HRV, or trends toward lower HRV, than nondepressed subjects, even after controlling for severity of CAD. Subject groups did not differ on left ventricular ejection fraction, history of myocardial infarction, or any other relevant medical variable assessed. These results suggest that depression is associated with decreased HRV in patients with CAD, and may help to explain the increased rates of cardiac events observed in CAD patients with depression.

Self-Complexity and Physiological Responses to Facial Self-Reflection: An Investigation into Women's Self-Image (open access)

Self-Complexity and Physiological Responses to Facial Self-Reflection: An Investigation into Women's Self-Image

In this study, effects of facial self-reflection and complexity of self on physiological responses were investigated. Skin conductance levels were measured during baseline and neutral conditions, then under a self-focusing condition provided by mirror reflection of the face. Subjects completed measures of self-complexity, depressive affect, self-esteem, anxiety and body image satisfaction. Eye tracking data was collected during the mirror condition. Results showed a significant effect of mirror self-reflection on physiological reactivity as measured by differences between mirror and baseline mean responses. Pre-test depressive affect was correlated with low self-esteem but not with self-complexity. Self-complexity was negatively correlated with orientation to physical appearance and positively correlated with greater differences between baseline and mirror mean reactivity. Self-complexity and depressive affect did not significantly predict physiological reactivity, although a trend was found for the influence of each variable. Post-hoc analyses showed significant group differences for both self-complexity and depressive affect on physiological reactivity, although the influence of self-complexity was in the unexpected direction. Results of this study are consistent with general findings that negative self-esteem, anxiety and depression are strongly correlated. In addition, a strong correlation was found between negative self-esteem and dissociative symptoms. Exploratory analyses of eye tracking data found no significant …

Effectiveness of the Neurobehavioral Cognitive Status Examination in Assessing Alzheimer's Disease (open access)

Effectiveness of the Neurobehavioral Cognitive Status Examination in Assessing Alzheimer's Disease

Accurate, early diagnosis of Alzheimer's Disease is becoming increasingly important in light of its growing prevalence among the expanding older-aged adult population. Due to its ability to assess multiple domains of cognitive functioning and provide a profile of impairment rather than a simple global score, the Neurobehavioral Cognitive Status Examination (NCSE) is suggested to better assess such patterns of cognitive deficit for the purpose of diagnosis. The performance of the NCSE was compared with that of the Mini-Mental State Examination (MMSE) for diagnostic sensitivity in a sample of patients diagnosed as having probable Alzheimer's Disease. The strength of correlation between severity of cognitive impairment on these tests and report of behavior problems on the Memory and Behavior Problems Checklist (MBPC) was also explored, as was performance on the NCSE and report of behavior problems using the MBPC in predicting Single Photon Emission Computed Tomography (SPECT) scan results. The NCSE was found to exhibit greater sensitivity to physician diagnosis of probable Alzheimer's Disease relative to two versions (Serial 7's or WORLD) of the MMSE (.90, .77 and .68, respectively). While both measures were found to correlate significantly with the report of behavior problems, only a moderate proportion (NCSE = .22 and …

Bias in the Diagnosis and Treatment of Gay Males

The purpose of this study was to explore heterosexual bias in the diagnosis and treatment of gay males. Two hundred-fifty (134 males and 116 females) mental health professionals from the Division of Psychotherapy (29) of the American Psychological Association participated in the study. Participants were randomly assigned to one of two case history conditions, which presented a 35-year-old male seeking therapy. Both conditions were equivalent with regards to the presenting problem (i.e., diagnostic symptoms) with the exception of his significant other (i.e., gay vs. non-gay condition). Potential bias was measured through a diagnostic rating Likert scale and a treatment plan questionnaire. Other independent variables that could potentially have an effect on diagnostic ratings were explored, such as gender, year of graduation, and theoretical orientation of the respondents. Results of the statistical analyses failed to confirm evidence of heterosexual bias. Implications for further research and training are discussed.

Individual Differences in Stress-Reactivity and the Influence of Self-Complexity on Coping Behaviour

The influence of self-complexity on coping behaviour and emotional adjustment is explored. The Role Construct Repertory Grid (REPGrid) Community of Selves procedure is used to assess self-complexity. Following a structured interview format, subjects completed a battery of measures including the REPGrid, Self-Rating Depression Scale, Hassles Scale, Major Stress Scale, and Coping Index. Results indicate that complex individuals utilize a wider variety of coping behaviours than less complex individuals, although the perceived severity of stressful events was. no different between groups. Micro-analyses at the individual self level revealed mixed or null results. Finally, more dysphoric individuals reported using more negative coping behaviours (drinking, smoking) than individuals not experiencing dysphoric mood. Findings are discussed a) in terms of the utility of the REPgrid in the assessment and understanding of self-complexity and its' relationship to mental health processes, b) in accordance with a person-event transactional model of health and illness, and c) in terms of the relevance to those psychotherapies that emphasize and encourage people to develop distinctions among their self-aspects, as well as new ways of construing the world, and new behavioural options, e.g. Fixed Role Therapy.

Comparing Quality of Life: American and Portuguese Cancer Patients with Hematological Malignancies

The purpose of this study is to investigate the differences and similarities of quality of life (QoL) in American and Portuguese cancer patients with hematological malignancies as well as the robustness of the measures cross-culturally. Portuguese participants were 98 patients and 49 accompanying persons and the American participants were 55 patients and 22 accompanying persons. Fifty (Portuguese sample) to 40% (American sample) of the patients came with an accompanying person who answered the questionnaire concerning the patient's QoL. The two cultural groups were characterized in terms of QoL (measured by the SF-36 and the FLIC), social support (Social Support Scale), socio-demographic and clinical variables. Portuguese patients reported a higher QoL. However, this result could be attributable to the fact that the two cultural samples differ in socio-economic status. The measures seem to be comparable for the Portuguese and American samples, at least in what concerns reliability and concurrent validity.

Comparing the Personal Lives of Psychotherapists and Research Psychologists (open access)

Comparing the Personal Lives of Psychotherapists and Research Psychologists

Although the personal life of the therapist has been a topic of interest for nearly sixty years there is still a paucity of research in this area. There is also a lack of research into the personal lives of researcher psychologists. In this study 282 psychologists (151 researchers and 131 therapists) who attended regional meetings and seminars sponsored by professional psychological associations in Texas were sampled. Job stressors, personal problems and health concerns, relaxation techniques, life satisfaction, and work impact on personal life were some of the areas examined. The most important stressors associated with research were excessive teaching responsibilities, pressures associated with funding and lack of time for a personal life. For therapists the most important stressors associated with work were suicide attempts by clients, clients showing resistance, and clients being angry. Therapists reported more concerns related to anxiety, depression, and family problems than researchers. Both groups chose exercise/sports and movies/television as their most common methods for relaxation. Therapists were three times more likely to have been in therapy than researchers and once in therapy reported six times the number of hours. Researchers reported less childhood abuse than therapists. However, therapists were more satisfied with their current life, indicating …
