Assertive Community Treatment (ACT) is designed to provide continuous, comprehensive support and services to individuals with severe mental health conditions, available 24/7.
Step-by-step explanation:
The service expected to provide resources 24 hours a day, 7 days a week for persons with serious mental illness is Assertive Community Treatment (ACT). The ACT model is designed to provide a range of services to individuals who are living with severe mental health issues and require consistent, round-the-clock support. This intensive, community-based service offers a team approach where mental health professionals collaborate to meet the varying needs of clients, delivering services in their own environment rather than a clinical setting. Unlike more traditional treatment models, ACT teams are available at all times and often assist with everything from therapy and medication management to help with daily living activities and crisis intervention.
