Factor analysis of the personal authority in the family system questionnaire.

The factor structure of the Personal Authority in the Family System Questionnaire (PAFS-Q) has been used in numerous studies, but the factor structure has not been examined since its development in 1984. This study examined the factor structure of the PAFS-Q. Findings suggest a six-factor solution with important differences from those reported when the PAFS-Q was developed. The main differences between this study and the original factor analysis are that this study found separate Mother and Father Intimacy factors instead of a single Intergenerational Intimacy factor and the original Spousal Fusion and Spousal Intimacy factors were not separate factors in the current study. Implications and future directions for research are also discussed.

The relationship between visual analysis and five statistical analyses in a simple AB single-case research design.

This study explored some practical issues for single-case researchers who rely on visual analysis of graphed data, but who also may consider supplemental use of promising statistical analysis techniques. The study sought to answer three major questions: (a) What is a typical range of effect sizes from these analytic techniques for data from "effective interventions"? (b) How closely do results from these same analytic techniques concur with visual-analysis-based judgments of effective interventions? and (c) What role does autocorrelation play in interpretation of these analytic results? To answer these questions, five analytic techniques were compared with the judgments of 45 doctoral students and faculty, who rated intervention effectiveness from visual analysis of 35 fabricated AB design graphs. Implications for researchers and practitioners using single-case designs are discussed.

The developmental course of Personal Authority in the Family System.

The present study examined the differences in participants' intergenerational family relationships across the following three age/stage groups based on Williamson's (1991) theory of Personal Authority in the Family System (PAFS) and adult developmental theory (Levinson, 1986): ages 18-23, 24-29, and 30-45. The most noteworthy variables were intergenerational intimacy and intimidation with mothers and fathers, with significant but less contribution by intergenerational triangulation with fathers. Results indicated that each successively older group reported significantly less intimacy and less intimidation with each parent, and less triangulation with fathers than the previous younger group. Small gender differences were also present, but without an interaction with age/stage groups. Females reported slightly healthier intergenerational relationships with parents than did males. Finally, implications for clinical practice are presented.

Solution-focused family therapy with three aggressive and oppositional-acting children: an N = 1 empirical study.

The efficacy of Solution-Focused Family Therapy (SFFT) for helping three families with aggressive and oppositional-acting children (aged 8-9) was examined. The N = 1 multiple-baseline design with three replications used validated measures, a treatment manual, and a treatment integrity measure. The interventions lasted from four to five sessions. SFFT appeared to be effective with the families at post-treatment and 3-month follow up.

Evaluation of the accuracy of two regression-based methods for estimating premorbid IQ.

Two premorbid IQ estimation procedures were compared in a normal, non-brain-impaired sample and a clinical sample of known brain-impaired individuals. The methods used for comparison were the purely demographically based regression index (DI) developed by and the Oklahoma Premorbid Intelligence Estimate (OPIE) equation by, which uses demographic information combined with current performance tasks. The data for the normal sample were gathered from the WAIS-R standardization sample of 1880 subjects. The clinical sample was 100 patients with known cognitive impairment who had been referred to a private neuropsychology practice. The DI appeared to provide the most clinical utility as an estimate of premorbid IQ in a cognitively impaired sample. Significant differences between the two methods for specific locations of brain injury were not observed.

Five-factor model (Big Five) personality traits and universal-diverse orientation in counselor trainees.

In this study the authors explored the relationship between five-factor model (FFM: Big Five) personality traits (J. M. Digman, 1990; R. R. McCrae & O. P. John, 1992; J. S. Wiggins & P. D. Trappnell, 1997) and universal-diverse orientation (UDO; M. L. Miville et al., 1999) in counselor trainees. FFM traits were measured using the NEO-Personality Inventory-Revised (P. T. Costa & R. R. McCrae, 1992). Statistically significant relationships were found between UDO and one of the Big Five personality traits (Openness to Experience) in counselor trainees. Further regression analysis suggested a relationship between UDO and a particular facet of Openness to Experience, Openness to Aesthetics. This finding suggests that counselor trainees who are open to the creative expressions of others may be comfortable working with a wide variety of clients. These results suggest that counselor training that encourages experiences of aesthetic diversity in addition to an exploration of values may promote trainees' ability to work with diverse clients.

Methodological and statistical considerations for threats to internal validity in pediatric outcome data: response shift in self-report outcomes.

OBJECTIVE: To examine conceptual models of response shift, research design, and internal validity issues in the context of longitudinal outcome research using self-report measures such as pediatric quality of life. METHODS: Growth modeling was introduced and illustrated using a previously published data set (Clay, Wood, Frank, Hagglund, & Johnson, 1995) of adjustment in children with juvenile rheumatoid arthritis, diabetes, and healthy controls. RESULTS: Demonstrations revealed that growth modeling may detect response shift and may also model the time and shape of the response shift. CONCLUSIONS: Growth modeling provides one avenue to investigate response shift, thereby addressing an important threat to internal validity in longitudinal outcome research such as quality of life in children with chronic illness.
