Exploratory and Confirmatory Factor Analysis of the Clinical Scales of the Luria-Nebraska Neuropsychological Test Battery, Form II

Description: The factor structure of the Luria Nebraska Neuropsychological Battery (LNNB) Form II was examined. A principle components factor analysis was performed on a sample of 102 psychiatric and neurologic subjects. It was necessary to remove 45 items from the analysis due to perfect performance by most subjects. The results were orthogonally rotated to simple structure using a Varimax method of rotation, and then compared to previous LNNB Form I and Form II results. Thirty-three factors were generated in the Exploratory Factor Analysis (EFA) . There was a very high agreement with the factors from Form I. Only one new factor was identified that didn't have a comparable Form I factor, and this factor appears to have neurological support. The similarity of the factor solutions between the two forms supports the continued use of factors derived from Form I for the interpretation of Form II, and supports the underlying structure presupposed by Lurian constructs. The present study also tested the significance of the hypothesized factor structures through confirmatory factor analysis (CFA). No hypothesis about the underlying factor structure based on previous exploratory studies was supported. The CFA did suggest that the best factor solution to the LNNB Form II is one that (a) has correlated factors and (b) has items loading on more than one factor. The confirmatory results were interpreted as not supporting the current exploratory results, or the previous factor analytic results. Problems notwithstanding, researchers may be better directed to propose factor models for the LNNB that have correlated factors, and to work samples approaching the 10 to 1 recommended sample size for multivariate analysis. One conclusion that was drawn from the concurrence between the two Form II studies pertains to psychiatric populations used in both studies. It was necessary to exclude a large number of items in each ...

Grandparents Raising Grandchildren: A Model of Psychological Functioning

Description: A sample of 203 grandparents, 103 of whom were surrogate parents for their grandchildren, were assessed to construct a model of their psychological functioning. Four measures of psychological functioning (i.e., well-being, satisfaction with grandparenting, meaning of grandparenthood, and perceived relationships with grandchildren) were evaluated. Path analysis of data suggested that the resumption of the parental role negatively impacted all measures except the meaning of grandparenthood. Data also suggested a sense of isolation among those raising grandchildren, as well as a sense of role confusion. These factors may have been exacerbated by behavior difficulties of many grandchildren as a result of family conflict preceding the loss of their parents, and by a lack of parenting skills of grandparents who assumed parental responsibilities. These results reinforce other work that found a preference for fulfilling voluntary, nonparental relationships with grandchildren among grandparents.

Personality Characteristics Associated with Pet Ownership: Validating the Theoretical Propositions of Boris Levinson

Description: The purpose of the present study was to provide validation for Levinson's theory about pets and human personality development. Levinson (1978) proposed that the personality development of individuals who have pets to which they are attached differs from that of those who do not have pets and that pets play an important role in facilitating the development of certain adaptive personality traits. In the present study, specific areas that were addressed included differences in certain personality characteristics between life-long pet owners who were strongly attached to their pets, life-long pet owners who were less strongly attached to their pets, and people who had owned pets for only a limited period of time in their lives. One hundred undergraduates completed the Pet Attitude Scale, the Tennessee Self Concept Scale, the Personality Research Form - Form E, the Hogan Empathy Scale, the Fundamental Interpersonal Relations Orientation - Behavior (FIRO-B), and the IPAT Anxiety Scale Questionnaire. No significant differences were found between the three pet owner groups in levels of affiliation with other people, impulse control, nurturance, succorance, capacity for empathy, and anxiety levels. In addition, no significant differences were found between the three pet owner groups in interpersonal behavior characteristics or self-esteem. Concurrent validity was shown between membership in the different pet owner groups and positive attitudes toward pets as measured by the Pet Attitude Scale. As predicted, the most attached life-long pet owners reported more positive attitudes toward pets than the least attached life-long pet owners or the limited-time pet owners.

Construct Use and Self-Aspect Change in Recovery From Coronary Artery Bypass Graft Surgery: a Personal Construct Analysis

Description: Cognitive ratings that use bipolar constructs based upon similarity and contrast have been shown to be biased towards the similarity pole in approximately a 62/38 ratio. This bias has also been known to shift in the contrastive direction for individuals who have psychiatric problems. This quantitative measure of cognitive change has a potential for characterizing cognitive changes that occur during the disease process, including recovery from disease. The present study investigated changes in self-aspect ratings and bipolar construct use in adult male veterans who had undergone coronary artery bypass graft surgery. Results indicated that treatment subjects' self-aspect and construct ratings were more negative than controls'. Results also indicated that all subjects rated core interpersonal self-aspects closest to the expected bias, while self-aspects related to cardiac recovery problems were rated in the most contrastive direction. The results finally suggested that the greatest degree of change for the treatment subjects were in emotionally generated constructs. The results suggested a preliminary validation for characterizing cognitive changes in the disease process by measuring shifts in bipolar construct ratings.

Control, Commitment, and Challenge: Relationships to Stress, Illness, and Gender

Description: Male and female college students were administered scales assessing their daily hassles, negative life events, control, commitment, challenge, psychological symptomatology, psychological distress, and physical symptomatology. Stepwise multiple regression analyses showed that control, commitment, and challenge act in an additive (rather than multiplicative) manner in relation to psychological and physical outcome measures.

The Relationship between Self-Reported Bulimic Behavior and Cardiovascular Reactivity to a Weight Stressor

Description: This investigation sought to identify anxiety responses to weight measurement, assessed by verbal report and cardiovascular reactivity CCR3 (systolic blood pressure, diastolic blood pressure, heart rate), which might differentiate females with either high or low self-reported bulimic behavior. Secondar i ly,, the study attempted to examine specific autonomic nervous system (ANS) arousal patterns of each group over time. The Bulimia Test (BULIT), Body Dissatisfaction Scale (BD), and a demographic questionnaire were administered to 105 undergraduate females at The University of North Texas. Based on BULIT scores, females were divided into high or low bulimic behavior groups. Of the 105 females screened, forty participated in the experiment which consisted of four phases: relaxation, anticipation of weight measurement, weight measurement, and recovery. Subjects had no prior knowledge of the weight stressor until presentation during the experiment. Results showed that subjects' notion of ideal weight was substantially lower than measured weight. During weight measurement, all subjects reported increased anxiety although the high group reported significantly more anxiety. Contrary to prediction, no significant group differences in CR were found when repeated measures multivariate analysis of variance (MANOVA) was performed. Orthogonal polynomial trend analysis was done with pooled groups, resulting in significant within-subject trends for all cardiovascular measures. There was also a significant group by time of measurement interaction for heart rate during the weight measurement phase. Correlational analyses failed to produce significant results between verbal report of anxiety and CR. There was, however, a significant correlation between BULIT and BD scores. It was concluded that heightened subjective anxiety during weight measurement could not be attributed to group differences in CR. Regarding ANS arousal patterns, mixed evidence of active and passive coping was seen. Nevertheless, both psychological and physiological measures supported an overvaluation of female thinness consistent with societal trends regardless of group membership. Implications ...

Factors Influencing Attitudes Toward Seeking Psychological Help in Younger and Older Adults

Description: The major purpose of this study was to test a hypothesized structural model that included many of the variables that have been found to influence people's attitudes toward seeking psychological help and investigate if these variables and their inter-relationships are different for young versus older adults. This study offers a more comprehensive investigation than previous research by testing and modifying two structural models of help-seeking attitudes, one for young adults and one for older adults. This makes it possible to examine how these variables differ for the two age groups.

Memory and Attention in the Healthy Elderly

Description: This study investigated the influence of age and health status on verbal and visual memory and attention. The objective was to select subjects resembling participants in normative studies, and to contrast the genuinely healthy component with the "contaminants." A rigorous and detailed self-report of health status plus a standard neurological examination were used to screen and divide subjects into two health status groups: normal and super healthy. It was speculated that the strong effect of age on memory and attention commonly found among the elderly would be diminished with more restrictive control over health status.

Relationship of Team Design and Maintenance on Performance and Satisfaction for Self-Directed Work Teams

Description: Five models for designing work teams from the Work Group Design Measure (Campion & Medsker, 1992b) and the models7 relationships to effectiveness criteria were compared using 30 self-directed work teams (SDWTs) in a manufacturing/production setting of a large defense contractor. The models which are from social psychology, socio-technical systems theory, industrial engineering, and organizational psychology include Job Design, Composition, Context/Resources, Potency/Interdependence, and Process. The study also examined distinguishing demographics, team characteristics, and interpersonal processes within the teams that differentiate higher performing teams and/or teams with higher job satisfaction. Effectiveness criteria were performance and job satisfaction. Among the findings, four of the five team design models (i.e., excluding the Composition Model), and the team-oriented interpersonal group processes correlated with performance and SDWT member job satisfaction.

Standardization of the Assessment of Competency to Stand Trial

Description: Evaluations of the Georgia Court Competency Test - Mississippi Version Revised (GCCT-MSH) and the Competency Screening Test (CST) have supported their use with pretrial defendants. The present study evaluated the efficacy of the measures with an inpatient population. Both measures were factor analyzed in an attempt to replicate; previously identified factor structures. Neither factor structure was replicated however, a distinct factor structure was identified for the GCCT-MSH. In addition, the relationship between sociodemographic variables, clinical variables, current symptomatology, and competency status were evaluated using discriminant functions analyses. The results suggest that the best predictors of incompetency in this sample are a diagnosis of a psychotic disorder or a non-psychotic affective disorder and a low measured IQ. Current symptomatology, as measured by the SCL-90-R, was not an effective predictor of competency status in this sample.

Dual Factor Socially Desirable Responding and Contrasts in Intrinsic and Extrinsic Religious Motivation

Description: A follow-up was done to Leak and Fish's (1989) study of intrinsically and extrinsically religious individuals using Paulhus' (1984) Balanced Inventory of Desirable Responding, a two factor scale of socially desirable responding measuring self-deceptive enhancement (SDE) and impression management (IM). 275 introduction to psychology students were group tested and categorized by gender and by religious orientation with Allport and Ross's (1967) fourfold Religious Orientation Scale (ROS). Differences between the four types were hypothesized on the religious relevance of the SDE and IM scale items. A difference score was also computed by contrasting two instructional sets on the BIDR as a measure of variation across situations. Measures of private and public self-consciousness, social anxiety, fear of negative evaluation, and self esteem were included.

The Effects of Cultural Bias: a Comparison of the WISC-R and the WISC-III

Description: It has been suggested that the use of standardized intelligence tests is biased against minorities. This study investigates the newly revised Wechsler Intelligence Scale for Children-III in which Wechsler states that the new scale has eliminated biased items. Comparisons of the scores on the WISC-R and the WISC-III of a clinical population of sixteen African American and eighteen Caucasian males, ages ten to sixteen, revealed significant differences between the two groups on the WISC-III. The minority scores decreased predictably from the WISC-R to the WISC-III, but the Caucasian scores increased rather than decreasing. The findings of this study do not support the predictions and goals of revision as stated in the manual of the WISC-III.

Neuropsychological Functioning of Blind Subjects with Learning Disabilities Compared to Those with Blindness Alone

Description: It has been hypothesized that a disproportionate percentage of the blind population are learning disabled. In the past, norms and technology were not available to assess in a cost effective manner the blind client's neuropsychological functioning. Norms for the Wide Range Achievement Test - Revised (WRAT-R2) are now available for a blind population without any neuropsychological dysfunctioning. This study utilized the adapted WRAT-R2 and the Comprehensive Vocational Evaluation System (CVES), a neuropsychological test battery adapted for the blind, to investigate the possibility that learning disabilities are present in the adult blind population. Suspected learning disabled, blind subjects were compared with normal blind subjects. There were significant neuropsychological differences between the two groups.
