The Adult Intensive Outpatient Program (IOP) provides similar clinical services as the Partial Hospitalization Program with less frequency. This program provides outpatient therapeutic and educational sessions organized at various levels of intensity and frequency. The IOP is for people who are experiencing mental or behavioral health conditions that do not necessitate residential or inpatient care. The program functions as an alternative to inpatient care, or as transitional care following an inpatient stay. The IOP caters to those who wish to receive mental health disorder treatment or co-occurring mental health plus substance use disorder treatment while maintaining their daily lives.
