Chapter 23: Community Mental Health Nursing

Community Mental Health Nursing provides a historical overview of care, moving from early confinement in asylums to the mid-twentieth-century era of deinstitutionalization, which often left individuals marginalized due to insufficient community resources. The text critically examines the "Advanced Psychiatric Society," highlighting how everyday human experiences are increasingly pathologized through expanding diagnostic criteria in manuals like the DSM, often influenced by the pharmaceutical industry. In response, grassroots movements such as the Psychiatric Survivors and Mad Movement have emerged to reclaim the agency and identity of those with lived experience. A significant portion of the chapter is dedicated to the social determinants of health, emphasizing how Adverse Childhood Experiences (ACEs), poverty, and social exclusion serve as foundational risk factors for psychological distress. Specific attention is paid to vulnerable populations, including Indigenous communities facing intergenerational trauma, military veterans, refugees, and those experiencing homelessness or substance misuse. The chapter outlines various service delivery models, such as Assertive Community Treatment (ACT), and promotes the Recovery Model, which focuses on hope, empowerment, and holistic well-being rather than just symptom management. For community health nurses, the role involves case finding, trauma-informed care, and "upstream" advocacy to address the systemic inequities—such as housing instability and discrimination—that underpin mental health challenges across the lifespan.
