Community mental health nursing provides prevention, treatment, and rehabilitation where people live, work, and learn, rather than in long-stay hospitals. Its goals are to help people with mental illness live stably and independently in the community, prevent relapse and rehospitalization, reduce stigma, and promote the mental health of the whole population.

Background: mid-20th-century deinstitutionalization moved people out of large psychiatric hospitals, helped by antipsychotic medication and civil rights reforms. Where community services were not funded adequately, many people became homeless or entered jails — which is why coordinated community care, housing, and crisis services matter.

Core principles

• Care in the least restrictive setting
• Continuity of care across settings
• Recovery orientation, self-determination, and social inclusion
• Population focus — prevention and promotion, not only treatment
• Interprofessional team approach built around the client's goals

Levels of prevention (Caplan)

Crisis theory. A crisis is a time-limited state in which usual coping fails. Types: maturational (developmental) — life transitions such as adolescence, marriage, retirement; situational — unexpected events such as job loss, divorce, illness, death; adventitious (social) — disasters, war, violent crime. Crises usually resolve within about 4–6 weeks, with growth, return to baseline, or lower functioning. Crisis intervention focuses on the here and now, is active and directive, and aims to return the person to at least the pre-crisis level of functioning.

Individual assessment in the community

• Safety first: suicide and violence risk, especially in a person in crisis or voicing suicidal ideas
• Symptoms, medication adherence and side effects, substance use
• Daily living skills, housing stability, income, food security
• Social supports, family burden, stigma experiences
• Physical health (people with serious mental illness die years earlier, mostly from preventable medical conditions)
• Early warning signs of relapse (sleep change, withdrawal, suspiciousness)

Populations needing special attention

• People experiencing homelessness — high rates of serious mental illness and substance use; outreach, "housing first" approaches, and flexible appointments help
• People in jails or prisons — screening, treatment during detention, and linkage to care at release
• Rural communities — distance and workforce shortages; telehealth and mobile teams expand access
• Older adults living alone — depression, suicide risk, and cognitive decline are often missed
• Disaster-affected communities — psychological first aid, then screening for PTSD and depression

Community assessment

• Needs assessment of residents' mental health problems and service needs
• Prevalence data, high-risk groups (unemployed, older adults living alone, people exposed to disaster)
• Available resources (clinics, crisis teams, peer groups, housing) and gaps

Community service continuum (least to most intensive)

Case management

• Goal: help the client live stably in the community by linking, coordinating, and monitoring services (treatment, housing, income, rehabilitation)
• Models range from brokerage (linking only) to intensive case management for people with severe disability needing frequent contact

Housing options range from 24-hour supervised residences to group homes, supported apartments, and independent housing (see Topic 12).

Medication in the community. Long-acting injectable antipsychotics can support adherence; nurses monitor for movement disorders, metabolic effects, and injection-site reactions (see Topic 9).

Listed in priority order.

1. Assess and manage immediate risk — in any crisis, assess suicide and violence risk first; arrange emergency care if needed
2. Crisis intervention — stay calm and directive; identify the precipitating event; assess perception of the event, supports, and coping; mobilize supports; plan concrete next steps; follow up
3. Case management and coordination — link clients to services; coordinate with other professionals through regular case conferences; each team member's expertise is respected and roles are shared, not monopolized
4. Monitor symptoms, adherence, and physical health during home visits and clinic contacts
5. Support families — provide information about the illness, coping skills, and emotional support; connect to family support groups. Families are partners, not replacements for professional care
6. Build social support — help establish and support self-help and peer groups; encourage community participation without making activities compulsory
7. Advocate — represent the client's rights and needs, help the client access services and entitlements, fight stigma, and promote the client's own voice (advocacy does not mean making decisions for the client or automatically siding against colleagues)
8. Primary prevention and education — stress management, parenting, school and workplace programs, anti-stigma campaigns

Community mental health nurse roles: case manager, clinician, educator, counselor, advocate, coordinator, researcher, and consultant.

• Know personal early warning signs of relapse and an action plan
• Keep follow-up appointments and medication supplies; know how to reach the team between visits
• Use peer support and self-help groups
• Avoid alcohol and drugs; maintain sleep, activity, and physical health checks
• Know crisis numbers (Country Notes) and when to go to emergency care

• Community care aims for stable, independent life in the community in the least restrictive setting
• Primary prevention = prevent occurrence (e.g., stress management for high-risk youth); secondary = early detection and treatment; tertiary = rehabilitation and relapse prevention
• Case management coordinates services so the client can live stably in the community; intensive case management / ACT for severe illness
• ACT: team-based, services delivered in the community, 24/7, low caseloads
• In a community crisis, assess suicide risk first
• Crisis: maturational, situational, adventitious; resolves in about 4–6 weeks; goal = pre-crisis level of functioning; here-and-now, directive
• Advocate = represent client rights and needs and connect resources
• Families need information and emotional support
• Program evaluation: process = how well sessions were delivered; outcome = client change; structure = resources
• Teams work collaboratively; no single profession monopolizes the role
