The purpose of this data collection was to explore the relationship between crime and mental disorder among jail inmates. Three sample groups were studied: jail inmates who had psychiatric contacts, jail inmates who did not have psychiatric contacts, and a control group of psychiatric patients who were not in jail. Psychiatric diagnosis history for inmates and patients with psychiatric contacts spanning 18 years (1960-1977) is available along with each subject's crime record and sentencing history. Variables include demographic characteristics, type of offenses sentenced, and number of arrests. Also included are psychiatric contact information including date of contact, diagnosis, type of service given, date of treatment termination, and reason for termination.
