Psychological correlates of eating disorders: Exploring the continuum perspective.

Description: Psychological and behavioral characteristics of female undergraduates with varying levels of disordered eating, as measured by the Questionnaire for Eating Disorder Diagnoses (Q-EDD; Mintz, O'Halloran, Mulholland, & Schneider, 1997), were investigated. Results suggest that the Q-EDD is an appropriate instrument for measuring eating disorder symptomatology. Greater disordered eating was associated with more bulimic, dieting, and weight fluctuation symptoms, higher impression management and approval-seeking needs, more dichotomous thinking, self control, and rigid weight regulation, and increased concern with body shape and dissatisfaction with facial features. Eating-disordered and symptomatic women evidenced more severe eating disorder behaviors and psychological distress than asymptomatic women. Findings are congruent with a redefined discontinuity perspective of eating disorder symptomatology. Treatment implications and campus-wide preventions are suggested.

Validation of the Spanish SIRS: Beyond Linguistic Equivalence in the Assessment of Malingering among Spanish Speaking Clinical Populations

Description: Malingering is the deliberate production of feigned symptoms by a person seeking external gain such as: financial compensation, exemption from duty, or leniency from the criminal justice system. The Test Translation and Adaptation Guidelines developed by the International Test Commission (ITC) specify that only tests which have been formally translated into another language and validated should be available for use in clinical practice. Thus, the current study evaluated the psychometric properties of a Spanish translation of the Structured Interview of Reported Symptoms (SIRS). Using a simulation design with 80 Spanish-speaking Hispanic American outpatients, the Spanish SIRS was produced reliable results with small standard errors of measurement (SEM). Regarding discriminant validity, very large effect sizes (mean Cohen's d = 2.00) were observed between feigners and honest responders for the SIRS primary scales. Research limitations and directions for future research are also discussed.

Methodological Issues in Malingering Research: The Use of Simulation Designs

Description: The accurate determination of malingering relies on the use of validated and clinically relevant assessment measures. Simulation design is the most often-used research design to accomplish this. However, its external validity is sometimes questioned. The goal of the thesis was to systematically evaluate these major elements: situation, incentives, and coaching. The situation in simulation studies can vary from relevant (academic failure in a college population) to irrelevant (capital murder) for the samples being studied. Incentives refer to the external motivation given to improve simulators' performance and can be positive (extra credit and monetary reward) or negative (extra time and effort). Finally, coaching refers to whether the participant receives any information on detection strategies that are designed to identify feigners. Using a large undergraduate sample in a factorial design, results indicate that a scenario familiar to the participants generally improved the believability of their responses. Coaching also improved the ability to feign convincingly, while incentive type was not associated with any change in scores. The implications of these findings for future research designs and the connection to practice are discussed.

Assessment of Psychopathy in Incarcerated Females

Description: Psychopaths constitute only an estimated 1% of the population, yet they are responsible for a disproportionately large number of violent and nonviolent crimes. The literature addressing this syndrome among male offenders is quite extensive. In contrast, psychopathy and its underlying factor structure remains understudied among female offenders. Research has suggested marked gender differences in the prevalence, clinical characteristics, and underlying dimensions of psychopathy. This study examined the dimensions of psychopathy in a female offender sample. The Psychopathy Checklist-Revised and the Self Report Psychopathy-II (SRP-II) were administered to 119 female inmates at Tarrant County Jail in Fort Worth, TX. Confirmatory factor analyses of the Psychopathy Checklist-Revised (PCL-R) did not support the use of the traditional two factor male model or a recently proposed two- factor female model. This thesis also addressed females' self-appraisal of PCL-R Factor 1 characteristics as well as the usefulness of the self-administered Self-Report Psychopathy-II as a screen for psychopathy.
