Core Types of Mental Health and Addiction Treatment Facilities in California
1. Acute Psychiatric Hospitals and Inpatient Psychiatric UnitsTypes of Behavioral Health Facilities in Arizona
Description:These are highly structured, hospital-based settings designed for individuals experiencing severe psychiatric crises or acute symptoms that pose a risk to themselves or others. Patients are admitted for intensive 24/7 care, stabilization, and medication management. Stays are typically short-term, ranging from a few days to a couple of weeks, with the goal of stabilizing acute symptoms before transitioning to a lower level of care.
Conditions Treated:
Schizophrenia and psychotic disorders
Severe depression and suicidal ideation
Acute mania
Severe anxiety and panic attacks
Substance-induced psychosis
2. Crisis Residential Treatment Facilities
Description: Crisis residential programs provide a home-like environment with 24-hour supervision for individuals in psychiatric crisis who do not require hospitalization but need more support than outpatient care can provide. These facilities are limited to 16 beds and offer intensive therapy, medication management, and support for up to 30 days.
Conditions Treated:
Acute exacerbations of mood disorders
Suicidal thoughts (without immediate risk)
Severe anxiety or PTSD episodes
Early psychosis
3. Long-Term Residential Treatment Centers
Description:Long-term residential facilities provide structured, therapeutic environments for individuals with chronic or severe mental health disorders or substance use disorders (SUDs) who require extended support. Stays can range from several months to over a year, with the focus on rehabilitation, skill-building, and community reintegration.
Conditions Treated:
Chronic schizophrenia or bipolar disorder
Severe depression with functional impairment
Dual diagnosis (co-occurring SUD and mental illness)
Complex trauma
4. Substance Use Disorder (SUD) Treatment Facilities
Description: These facilities specialize in treating drug and alcohol addiction through a continuum of care, including detox, residential, and outpatient services. Programs are often tailored to specific substances (e.g., opioid, alcohol, methamphetamine) and may offer gender-specific or age-specific tracks.
Levels of Care:
Detox: Medically supervised withdrawal management, often the first step in recovery.
Residential/Inpatient: 24/7 care in a structured environment, typically 20–90 days.
Outpatient: Flexible programs allowing clients to live at home while attending therapy and support groups.
Conditions Treated:
Alcohol use disorder
Opioid use disorder (heroin, prescription painkillers)
Stimulant use disorder (methamphetamine, cocaine)
Polysubstance abuse
5. Dual Diagnosis Treatment Centers
Description: Dual diagnosis facilities are designed for individuals with both a mental health disorder and a substance use disorder. These centers provide integrated care, meaning psychiatric and addiction treatments are delivered simultaneously by a multidisciplinary team.
Conditions Treated:
Depression and alcohol addiction
Bipolar disorder and stimulant use
PTSD and opioid use
Anxiety and prescription drug abuse
Importance:Over half of individuals with substance use disorders also have a co-occurring mental illness, making integrated dual diagnosis care essential for effective recovery.
6. Outpatient Treatment Programs
Description:Outpatient programs offer therapy, counseling, and medication management for individuals who do not need 24-hour supervision. These programs allow clients to maintain work, school, and family responsibilities while receiving care.
Types:
Partial Hospitalization Programs (PHPs): Intensive day treatment, 20+ hours/week.
Intensive Outpatient Programs (IOPs): 9–19 hours/week, focused on relapse prevention and coping skills.
Standard Outpatient: Less than 9 hours/week, ideal for maintenance and step-down care.
7. Community-Based and Supportive Housing Programs
Description: These programs provide transitional or long-term housing with varying levels of support for individuals with behavioral health needs. They bridge the gap between inpatient/residential care and independent living, often including case management, peer support, and vocational services.
Examples:
Sober living homes
Supportive housing for people with serious mental illness
Community mental health centers
8. Telehealth and Virtual Therapy Services
Description:California has rapidly expanded telehealth services, especially for youth and families, offering virtual therapy, coaching, and crisis support via secure online platforms. These services increase access in rural and underserved areas.

Cognitive Behavioral Therapy (CBT)

Combines CBT with mindfulness and acceptance strategies. Particularly effective for borderline personality disorder, emotional dysregulation, and self-harm.
Medication-Assisted Treatment (MAT)
Combines medications (e.g., methadone, buprenorphine, naltrexone) with counseling to treat opioid and alcohol use disorders. Increases retention and reduces relapse rates.
Trauma-Informed Care
Recognizes the impact of trauma on mental health and addiction, integrating safety, trust, and empowerment into all aspects of treatment.
Motivational Interviewing
A client-centered approach that helps individuals resolve ambivalence about change, often used in early recovery.
Family Therapy and Support
Engages family members in the recovery process, improving outcomes for both mental health and addiction.
Holistic and Experiential Therapies
Includes yoga, art therapy, equine therapy, and recreational therapy, supporting overall wellness and coping skills.
Success Rates and Outcome Data
Treatment Retention: Longer stays in treatment (especially 90+ days) are strongly correlated with better outcomes and reduced relapse.
Dual Diagnosis: Individuals with co-occurring disorders often have lower success rates if both conditions are not treated simultaneously; integrated care significantly improves outcomes.
MAT Programs: Medication-assisted treatment for opioid use disorder increases retention and reduces relapse by 50% or more compared to non-MAT approaches.
Service Intensity: Greater service intensity and patient satisfaction are linked to higher rates of treatment completion and long-term recovery.
Barriers: California faces a shortage of behavioral health professionals and treatment beds, with nearly one-quarter of adults with mental illness unable to access needed care.

Proposition 1 (2024): Allocates over $6 billion to expand behavioral health treatment beds, supportive housing, and workforce development, aiming to address homelessness and behavioral health needs.
Telehealth Expansion: New state-funded platforms and apps provide free, accessible mental health support for youth and families, addressing provider shortages and increasing reach.
