The Role of a PHP program in Dual Diagnosis Treatment
Clinically Reviewed by Dr. Kate Smith

When a person struggles with both a mental health disorder and a substance use disorder (SUD), they require comprehensive, integrated care—a treatment approach known as dual diagnosis treatment. Since mental health issues and addiction feed into each other, treating one condition without addressing the other often leads to relapse and ineffective recovery.
A Partial Hospitalization Program (PHP) plays a crucial role in dual diagnosis recovery, offering intensive therapy, medication management, and structured care while allowing individuals to return home in the evenings. At Greater Boston Addiction Centers, our PHP for dual diagnosis in Boston provides individuals with personalized, evidence-based treatment designed to address both mental health challenges and substance dependency simultaneously.
This article explores the importance of PHP in dual diagnosis treatment, including its benefits, therapy options, the role of medication-assisted treatment (MAT), and what to expect during PHP care.
Understanding Dual Diagnosis: Why Treating Both Conditions Matters
Dual diagnosis occurs when an individual has both a substance use disorder (SUD) and a co-occurring mental health disorder. These conditions are interconnected—mental illness can contribute to substance abuse, and prolonged substance use can worsen mental health symptoms.
Common Mental Health Disorders That Co-Occur with Addiction
- Depression → Often linked with alcohol or opioid abuse.
- Anxiety Disorders → Frequently associated with benzodiazepine dependence.
- Post-Traumatic Stress Disorder (PTSD) → Strongly connected to opioid, alcohol, or stimulant addiction.
- Bipolar Disorder → Leads to extreme highs and lows, often accompanied by substance misuse.
- Schizophrenia and Psychotic Disorders → Can be worsened by marijuana, stimulants, or alcohol abuse.
Without integrated dual diagnosis treatment, these conditions fuel one another, making long-term recovery difficult. A Partial Hospitalization Program (PHP) offers the structured support needed to manage both conditions effectively.
How a PHP Program Supports Dual Diagnosis Treatment
A Partial Hospitalization Program (PHP) is an intensive treatment option that provides structured, full-day therapy sessions while allowing patients to return home at night. For dual diagnosis patients, PHP combines mental health treatment and addiction therapy into a single, unified program.
1. Comprehensive Assessment & Personalized Treatment Plans
- A psychiatric evaluation to identify underlying mental health disorders.
- Medical assessments to determine the severity of substance dependence.
- Individualized treatment planning to address both addiction and mental health needs.
2. Integrated Therapy for Mental Health and Addiction
PHP treatment includes both evidence-based and holistic therapies, such as:
- Cognitive Behavioral Therapy (CBT): Helps manage negative thoughts and prevent substance use triggers.
- Dialectical Behavior Therapy (DBT): Teaches emotional regulation and coping skills.
- Group Therapy Programs: Provides peer support and shared recovery experiences.
- Family Therapy Programs: Helps loved ones understand and support recovery.
- Mindfulness & Stress Reduction: Includes yoga, meditation, and exercise to promote emotional well-being.
3. Medication-Assisted Treatment (MAT) for Dual Diagnosis
For individuals struggling with severe withdrawal symptoms or cravings, MAT may be incorporated into PHP to improve recovery outcomes. Some commonly used medications include:
- Suboxone (Buprenorphine) and Methadone for opioid use disorder.
- Naltrexone (Vivitrol) for alcohol or opioid dependence.
- Antidepressants and mood stabilizers for depression, anxiety, and bipolar disorder.
The Benefits of PHP for Dual Diagnosis Patients
1. Intensive Yet Flexible Treatment
PHP provides a high level of care similar to inpatient rehab, but patients can return home at night, allowing for a balance between treatment and personal responsibilities.
2. Daily Support & Monitoring
Patients in PHP receive daily check-ins and therapy sessions, ensuring immediate intervention if mental health symptoms or cravings become overwhelming.
3. Focus on Relapse Prevention
Since mental health symptoms often trigger substance use, PHP teaches coping strategies to manage:
- Emotional distress.
- High-risk situations.
- Triggers that lead to relapse.
4. Medication Management for Stability
Patients receive continuous medication monitoring to ensure that psychiatric medications are effectively managing their mental health symptoms without contributing to substance misuse.
5. Gradual Transition to Independent Living
Rather than moving from inpatient rehab directly to outpatient care, PHP allows individuals to adjust to daily life while still receiving structured support.
PHP vs. Other Levels of Dual Diagnosis Treatment
Treatment Level | Duration | Best For | Treatment Schedule |
---|---|---|---|
Inpatient Rehab | 30-90 days | Severe addiction, detox, 24/7 supervision | Full-time residential care |
Partial Hospitalization Program (PHP) | 4-6 weeks (average) | Individuals with dual diagnosis needing intensive therapy | 5-6 hours per day, 5 days a week |
Intensive Outpatient Program (IOP) | 6-12 weeks | Individuals transitioning from PHP or inpatient care | 3-5 therapy sessions per week |
Outpatient Program (OP) | Ongoing | Long-term support for recovery maintenance | 1-2 therapy sessions per week |
The Role of Peer and Family Support in PHP
1. The Importance of Group Therapy
Many individuals with dual diagnosis feel isolated due to the stigma surrounding mental illness and addiction. Group therapy in PHP allows individuals to:
- Connect with others who share similar struggles.
- Gain insight and support from peers.
- Practice healthy communication and social skills in a safe environment.
2. Family Therapy for Long-Term Recovery
Family members often struggle to understand dual diagnosis, which can lead to miscommunication and conflict. PHP incorporates family therapy to:
- Educate loved ones about mental health and addiction.
- Teach healthy boundaries and support strategies.
- Rebuild trust and communication in relationships.
Transitioning from PHP to Long-Term Recovery
Once patients stabilize in PHP, they often transition to less intensive treatment options, such as:
- Intensive Outpatient Program (IOP) – Offers continued therapy with flexible scheduling.
- Outpatient Program (OP) – Provides long-term relapse prevention strategies.
- Sober Living Programs – Recommended for those needing additional structure before full independence.
A personalized aftercare plan ensures ongoing success beyond PHP treatment.
