ABSTRACT The present study investigated the performance of indices of schizophrenia from the Personality Assessment Inventory (PAI-SCZ; L. C. Morey, 1991) and Rorschach (Rorschach SCZI; J. E. Exner, 1993) in a heterogeneous sample of 24 inpatients at a public psychiatric hospital in the southeastern United States. Results indicated modest agreement between the PAI-SCZ and Rorschach SCZI. More important, the PAI-SCZ but not Rorschach SCZI reliably differentiated inpatients with schizophrenic-spectrum diagnoses from inpatients with other psychiatric diagnoses. In settings in which psychotic disorders falling outside the schizophrenic spectrum are common, the PAI-SCZ may be better suited than the Rorschach SCZI to aid in the differential diagnosis of schizophrenia.

    ABSTRACT: This study contributes to the ongoing construct validation of the Personality Assessment Inventory (PAI; Morey, 1991 , 2007 ) by identifying nontest life-event correlates of the PAI full scales and subscales in a sample of psychiatric patients. The life-event data used in this study included education, marital status, and employment, as well as a history of suicide attempts, psychiatric hospitalizations, trauma, medical problems, hallucinations, paranoid ideation, drug abuse, alcohol abuse, and arrest. Correlations were calculated to explore the convergent and discriminant validity of the PAI scales relative to the life-event data. The results showed that the majority of the PAI scales (11 of 13) had meaningful correlations with at least 1 life-event variable. The PAI BOR scale had the greatest number of correlations and was associated with 8 life-event variables. In contrast, the PAI ANX and MAN scales had no correlations above a predetermined threshold (r ≥.21). These findings add to the growing body of empirical correlates of the PAI and generally provide support for the construct validity of the PAI scales.

    ABSTRACT: The integration of cognitive neuroscience with neuropsychology has been advocated (Stuss & Levine, 2002). Lichter and Cummings' (2001) description of "circuit specific behavioral syndromes" suggested that an "orbitofrontal (OF) syndrome" could be discriminated from a "dorsolateral-prefrontal (DLPF) syndrome," based on a theoretical model of frontal-subcortical circuits. Using Morey's (1991) Personality Assessment Inventory (PAI), a cluster variate of antisocial features, aggression, mania, and obsessive-compulsive behavior was selected to partition a diagnostically heterogeneous, archival sample of clinic-referred college students (N = 22) using cluster analysis. A two-group cluster solution emerged from the results of combined hierarchical-agglomerative and iterative partitioning procedures, potentially corresponding to the putative OF and DLPF classifications. The "OF profile group" obtained significantly higher scores on self-report measures of antisocial features, aggression, mania/hypomania, and obsessive-compulsive behavior than the "DLPF profile group." External validation of the cluster solution employing univariate logistic regression analyses suggested the DLPF profile group performed more poorly than the OF profile group on measures of sustained attention and spatial working memory, and the OF profile group performed more poorly than the DLPF profile group on a measure of color naming. Utilizing the PAI in conjunction with neuropsychological tests to assist in identifying OF and DLPF neurobehavioral profiles is suggested. Implications for treatment and academic accommodations for clinic-referred college students are discussed.
