The current study used confirmatory factor analysis to examine the factor structures of two instruments commonly used in the assessment of competency to stand trial—the MacArthur Competence Assessment Tool—Criminal Adjudication (MacCAT-CA) and the Brief Psychiatric Rating Scale (BPRS). Results revealed support for the three-subscale factor structure of the MacCAT-CA defined by the authors of the instrument; for a slightly altered three-factor structure defined by Zapf, Skeem, and Golding (2005, Psychological Assessment, 17, 433–445); and for the four symptom clusters of the BPRS as defined by Hedlund and Vieweg (1980, Journal of Operational Psychiatry, 11, 48–63). In addition, exploratory factor analysis of all 24 items of the BPRS revealed a five-factor structure. Correlations between psychiatric symptoms, symptom clusters, and competence-related abilities were also examined using the previously identified and the newly identified factor structures of the MacCAT-CA and the BPRS. Significant relations between symptoms and psycholegal abilities are discussed.
