Introduction to Partial Hospitalization Programs in Boston
Recovery from substance use disorders requires a structured, evidence-based approach. While inpatient rehab provides 24/7 care, many individuals benefit from a Partial Hospitalization Program (PHP), which offers intensive treatment without requiring overnight stays.
At Greater Boston Addiction Centers, our PHP treatment program is designed to provide comprehensive addiction therapy in Boston, allowing individuals to receive full-day structured treatment while returning home at night. A common question from those considering PHP is: How long does a PHP program last?
The length of a Partial Hospitalization Program depends on factors such as addiction severity, co-occurring mental health conditions, personal progress, and external responsibilities. This article will explore the standard duration of PHP, factors influencing treatment length, what to expect in a PHP, and how it compares to other treatment levels.
What Is a Partial Hospitalization Program (PHP)?
A Partial Hospitalization Program (PHP) is an intensive, full-day addiction treatment program that serves as a bridge between inpatient rehab and outpatient care. It is ideal for individuals who require structured therapy, medical support, and relapse prevention strategies but do not need 24/7 inpatient supervision.
Key Features of PHP Treatment in Boston
- 5-6 hours of therapy per day, five days a week
- Individual and group therapy sessions focused on addiction recovery
- Medication-assisted treatment (MAT) for opioid and alcohol addiction if needed
- Family therapy and peer support groups to strengthen relationships
- Relapse prevention education and coping skills development
- Holistic approaches such as mindfulness, yoga, and fitness therapy
- Dual diagnosis treatment for co-occurring mental health disorders
A PHP program provides the structure and accountability needed for long-term sobriety while allowing individuals to practice independent living skills.
How Long Does a PHP Program Last?
Typical Duration of a PHP Program
The duration of a Partial Hospitalization Program varies, but most programs last between:
- 2 to 4 weeks (short-term PHP): Best for individuals with mild addiction or those transitioning from inpatient rehab.
- 4 to 6 weeks (standard PHP): The most common duration for those needing structured therapy, medical support, and relapse prevention training.
- 6 to 8 weeks (extended PHP): Recommended for individuals with severe addiction, co-occurring mental health conditions, or a high risk of relapse.
While the average PHP duration is about 4-6 weeks, some individuals require longer treatment for a stable recovery foundation.
Factors That Influence the Length of a PHP Program
Several factors determine how long a PHP program lasts:
1. Severity of Addiction
Individuals with mild to moderate substance use disorders may complete a 4-week PHP program, while those with severe addiction may require 6-8 weeks of PHP treatment before transitioning to an Intensive Outpatient Program (IOP) or Outpatient Program (OP).
2. Co-Occurring Mental Health Disorders
Many individuals in substance abuse treatment programs also struggle with depression, anxiety, PTSD, or bipolar disorder. These individuals often require a longer PHP duration (6+ weeks) to address both addiction and mental health challenges effectively.
3. Medical and Medication Needs
Patients undergoing medication-assisted treatment (MAT) for opioid or alcohol use disorder may need an extended PHP plan to monitor medication efficacy and manage withdrawal symptoms.
4. Individual Progress in Therapy
PHP treatment is individualized, meaning that progress is regularly assessed to determine if continued PHP care is necessary. Some individuals transition to IOP sooner, while others extend PHP for additional therapy and relapse prevention.
5. Home Environment and Support System
Individuals with a supportive home environment may progress faster and transition to IOP or OP more quickly. However, those without a stable or supportive home may require a longer PHP duration or transition to a sober living home before stepping down to a lower level of care.
What to Expect During a PHP Program
1. Comprehensive Addiction Therapy
Individuals in PHP participate in multiple therapy sessions per day, including:
- Individual Therapy: Personalized one-on-one counseling to address the root causes of addiction.
- Group Therapy: Peer support sessions focused on shared experiences and coping strategies.
- Family Therapy: Strengthening relationships and addressing family dynamics that impact recovery.
2. Holistic and Behavioral Therapies
A successful addiction treatment program in Boston incorporates holistic and behavioral therapies to promote overall well-being. These may include:
- Cognitive-Behavioral Therapy (CBT) and Dialectical Behavior Therapy (DBT)
- Mindfulness meditation and stress reduction techniques
- Physical wellness activities, such as yoga or guided exercise
3. Relapse Prevention and Coping Skills Training
PHP provides structured education on:
- Recognizing and managing triggers
- Developing healthy coping mechanisms
- Avoiding high-risk situations
- Building a sober support network
PHP vs. Other Levels of Addiction 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 needing intensive therapy but can live at home | 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 |
Transitioning from PHP to IOP or OP
Once individuals complete their PHP treatment, they often transition to less intensive treatment programs, such as:
- Intensive Outpatient Program (IOP): Structured therapy (3-5 sessions per week) with more flexibility.
- Outpatient Program (OP): Long-term recovery support through weekly therapy and relapse prevention.
- Sober Living Programs: A transitional option for those needing additional structure before independent living.
Transitioning from PHP to IOP ensures that individuals continue receiving support as they reintegrate into daily life.

FAQs About PHP Duration
How long does a PHP program usually last?

What factors determine the length of a PHP program?
The length of a PHP depends on:
- Severity of addiction (mild, moderate, or severe substance use disorder).
- Co-occurring mental health conditions such as anxiety, PTSD, or depression.
- Medical and medication needs, including medication-assisted treatment (MAT).
- Progress in therapy and response to addiction treatment.

Can I extend my PHP treatment if needed?
Yes! Many individuals extend their PHP beyond 4-6 weeks if they require additional support before transitioning to an Intensive Outpatient Program (IOP) or Outpatient Program (OP).
What happens after completing PHP?
After completing PHP, most individuals step down to a lower level of care, such as:
- Intensive Outpatient Program (IOP) (3-5 therapy sessions per week).
- Outpatient Program (OP) for continued support (1-2 therapy sessions per week).
- Sober living programs for additional structure and accountability.
Is PHP the same as inpatient rehab?

PHP is a critical step in the recovery process, but continued care through IOP, OP, and aftercare programs greatly increases long-term sobriety success rates.
