Factors Correlated with Psychiatric Recommendations of Incompetency and Insanity

Abstract

One hundred and twenty criminal defendants referred to a state hospital forensic unit underwent extensive examinations for the purpose of arriving at psychiatric recommendations regarding competency to stand trial and criminal responsibility. Seventy variables were abstracted from these evaluations via use of a simple checklist. A series of discriminant function analyses utilizing these variables indicated that highly accurate predictions could be made regarding psychiatric recommendations with respect to both competency and responsibility. Factors most influential in determining these recommendations included mental status at the time of the offense, psychotic symptomatology, and DSM-III diagnoses.
