This study examines potential gender differences among defendants referred by criminal courts for psychiatric evaluations by analyzing demographic, clinical, and criminal history variables and evaluation findings. This study offers a large sample size of 718 females, as well as 3,627 males. Bivariate logistic regression and heterogeneity analyses were utilized to assess potential differences. Females were older; diagnosed more with mood, anxiety, and borderline personality disorders; less likely to have prior felony convictions; and more likely to be in the community than jail at the time of the evaluation. In addition, when controlling for other factors, females were more likely to be evaluated as having a mental disease or defect, to need hospitalization pending trial, and to be incompetent to stand trial.
