Assertive Community Treatment (ACT) is designed to provide treatment, rehabilitation and support services to individuals who are diagnosed with a serious mental illness and whose needs have not been met by more traditional mental health services. The ACT team provides individualized services that are tailored to meet the specific needs of the person receiving those services. The ACT team members have expertise in psychiatry, nursing, psychology, social work, substance abuse and vocational rehabilitation. The ACT team collaborates with the person receiving services to provide integrated services designed to meet needs and goals over time. The staff-to-recipient ratio for the ACT team is small, with one clinician for every ten recipients. Services are provided 24-hours a day, seven days a week, for as long as they are needed.
