CTI is an empirically supported, time-limited case management model designed to prevent homelessness and other adverse outcomes in people with mental illness following discharge from hospitals, shelters, prisons and other institutions. CTI was originally developed and tested by researchers and clinicians at Columbia University and New York State Psychiatric Institute with significant support from the National Institute of Mental Health and the New York State Office of Mental Health. The model is listed in the National Registry of Evidence-Based Programs and Practices and is currently being applied and tested in the US and abroad.  Download a four-page handout here.
