This systematic literature review delves into the utilization of mental health interventions in community settings to effectively assist patients with mental illness. By examining interventions that reduce the signs and symptoms of mental illness, this review aims to decrease hospitalization rates and improve the quality of life for individuals deserving of proper care. The selected timeframe for this literature review spans from 2008 to 2016, and various electronic databases were explored, including MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and SAGE Journal, which encompass articles from the International Journal of Social Psychiatry, Journal of the American Psychiatric Nurses Association, and PsycINFO databases. Additionally, digital dissertations and theses available through Google Scholar were included in the search. The search terms focused on mental health interventions in community-based settings. The reviewed literature provides evidence of the effectiveness of diverse mental health interventions implemented in community settings. However, it also highlights the scarcity of mental health interventions available to patients with mental illness worldwide. Through this comprehensive literature review, a deeper understanding of mental health interventions in community settings can be gained, ultimately informing, and improving future approaches in this crucial area of care.
