RESUMEN
In this study, we examined the diagnostic efficiency of the Personality Assessment Inventory (PAI; Morey, 1991) for the assessment of posttraumatic stress disorder (PTSD) in a community-based sample of women (n = 128). Receiver operating characteristic curves (ROC) were generated to examine the efficiency of the PAI PTSD LOGIT function as a tool for diagnosing PTSD. Using the Clinician Administered PTSD Scale as the reference standard, the PTSD LOGIT function performed well (area under the curve [AUC] = .856, standard error [SE] = .034). This represents performance consistent with more commonly used self-report PTSD scales, the Davidson Trauma Scale (AUC = .863, SE = .033) and the PAI Anxiety subscale Anxiety-Related Disorders Traumatic Experiences (AUC = .861; S.E. = .033). Results of this study suggest that the PAI PTSD LOGIT function may be a useful tool in assessing PTSD.

In this study, we compared protocol validity rates between the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) and the Personality Assessment Inventory (PAI; Morey, 1991) in a veteran population. Veterans (N=472) were administered both instruments as part of routine psychological evaluations. Profile validity was based on previously published criteria. When applying primary validity indicators, inpatients produced significantly fewer invalid PAI profiles (37%) than MMPI-2 profiles (63%). We found similar results among outpatients for which we considered 47% of MMPI-2 profiles invalid compared to only 21% of PAI profiles. When applying both primary and supplementary validity indicators, both inpatients and outpatients continued to produce fewer invalid PAI profiles than MMPI-2 profiles. We discuss factors that may be related to the differences in validity rates.

The aim of the present study was to investigate the possibility of sex bias in the diagnostic criteria for borderline, schizotypal, avoidant, and obsessive-compulsive personality disorders. A clinical sample of 668 individuals was evaluated for personality disorder criteria using a semistructured interview, and areas of functional impairment were assessed with both self-report and semistructured interview. The authors used a regression model of bias to identify bias as differences in slopes or intercepts between men and women in the relationship between each diagnostic criterion and level of impairment. The results suggest that most of the diagnostic criteria examined do not seem to display sex bias. However, those criteria that displayed evidence of bias came largely from the borderline diagnosis.
