If you or a loved one is facing mental health challenges, navigating the different levels of care can feel overwhelming. You may have heard of Partial Hospitalization Programs (PHP) and Intensive Outpatient Programs (IOP), but understanding the differences—and knowing which one is right for you—isn’t always clear.
At Greater Boston Behavioral Health, we offer both PHP and IOP as part of our comprehensive Mental Health Programs in Boston. These programs are designed to support individuals with anxiety, depression, trauma, mood disorders, and other mental health conditions—without the need for full inpatient hospitalization.
In this article, we break down the core differences between PHP and IOP, explain who benefits most from each, and help you make an informed decision about your mental health care.
What Is a Partial Hospitalization Program (PHP)?
A Partial Hospitalization Program is the most intensive level of outpatient care available. PHP provides structured, full-day treatment—typically 5 days a week for 4–6 hours per day—while allowing clients to live at home or in a supportive environment.
At Greater Boston Behavioral Health, our Partial Hospitalization Program in Boston includes:
- Daily group therapy sessions
- Weekly individual therapy
- Psychiatric evaluation and medication management
- Cognitive Behavioral Therapy Boston (CBT)
- Dialectical Behavior Therapy in Boston (DBT)
- Trauma-informed care
- Psychoeducation and life skills training
- Support for co-occurring disorders, including substance use
PHP is ideal for individuals who need significant support to stabilize symptoms, develop coping skills, and prevent hospitalization—but who do not require 24/7 supervision.
What Is an Intensive Outpatient Program (IOP)?
An Intensive Outpatient Program offers a step down from PHP, providing therapeutic care several times per week—typically 3–5 days a week for 2–4 hours per session.
Our Intensive Outpatient Program in Boston includes:
- Weekly individual therapy sessions
- Group therapy focused on emotional regulation, trauma, and relapse prevention
- Skills groups utilizing CBT and DBT techniques
- Medication management through Psychiatric Care in Boston
- Specialized services like Anger Management Therapy in Boston
IOP is designed for individuals who are experiencing moderate symptoms and need more than weekly therapy—but are still able to maintain work, school, or family responsibilities.

Who Benefits Most from PHP?
You may benefit from PHP if you:
- Recently discharged from inpatient or Residential Treatment Program in Boston
- Are experiencing frequent emotional crises or mood swings
- Have suicidal thoughts (but are not at immediate risk requiring 24-hour care)
- Struggle with daily functioning due to depression, trauma, or anxiety
- Need intensive support to avoid inpatient admission
- Require daily psychiatric care to manage medications and symptoms
PHP creates a safe, supportive, and structured environment that promotes stabilization and recovery—especially for individuals with complex diagnoses.
Who Benefits Most from IOP?
IOP may be right for you if you:
- Have completed PHP or inpatient care and are ready for a step-down
- Are managing work or school but need more support than weekly therapy
- Are experiencing moderate levels of depression, anxiety, or trauma symptoms
- Want to strengthen coping strategies to prevent relapse
- Need accountability and consistency while rebuilding independence
IOP allows you to work on your mental health without pausing your life, providing the therapeutic foundation to build lasting emotional stability.
How Therapy Differs in PHP vs. IOP
At Greater Boston Behavioral Health, both PHP and IOP utilize evidence-based therapies, but differ in intensity and delivery.
In PHP:
- You may participate in multiple therapy groups per day
- You’ll have more frequent access to your individual therapist
- Medication management is reviewed more regularly
- Deeper exploration of trauma, mood dysregulation, and co-occurring issues is possible
- Greater structure helps reduce emotional volatility or crisis episodes
In IOP:
- You attend fewer groups per week, allowing time for external responsibilities
- Therapy focuses on skill reinforcement, goal setting, and building routines
- Greater emphasis on real-world application of techniques learned
- Ideal for maintaining progress and transitioning back to daily life
Both programs include trauma-informed care, group support, family therapy, and specialized treatments such as anger management and mindfulness training.
When to Transition from PHP to IOP
Often, a continuum of care is the best approach. After achieving stability in PHP, many clients naturally transition to IOP for continued growth. This step-down approach allows for:
- Greater independence while maintaining therapeutic support
- Time to re-engage with work, school, or personal goals
- Continued medication management and symptom monitoring
- Reduced risk of relapse or regression
Our team ensures that transitions between PHP and IOP are smooth, intentional, and personalized, based on clinical progress and individual readiness.
