For those overcoming a substance use disorder or mental illness, tailored treatment is the key to developing effective coping strategies, building new habits and finding support. While inpatient care offers the highest level of structure and support, it’s not practical or necessary in all cases. Partial hospitalization and intensive outpatient programs offer individualized care, making them effective for treating mental illness. In fact, one study found individuals receiving outpatient therapy were significantly less likely to engage in substance use, indicating outpatient treatment can be as effective as residential programs in certain cases.
Below, we compare IOP vs. PHP by looking at their key differences and considering who may benefit from each format. We also outline factors to consider as you choose between these options and discuss how Restore Mental Health can help you or your loved one achieve long-term recovery.
What Is a Partial Hospitalization Program (PHP)?
A partial hospitalization program is an intensive, structured form of treatment. It’s for people who need more support than traditional outpatient care but don’t require or aren’t able to accommodate 24-hour inpatient care. At Restore Mental Health, PHPs typically take place on weekdays, starting at 7 a.m. and lasting until 3 p.m., though evening and weekend hours may be available. Typically, individuals spend about 25–30 hours each week in treatment, attending therapy during the day and going home in the evening.
PHP offers a mix of medical monitoring, one-on-one and group therapy, education and skill-building. Individuals learn the strategies they need to stabilize their mental health or address substance use disorders. Some people transition to this level of care after completing an inpatient treatment program, while others begin treatment in this format in place of inpatient care.
What Is an Intensive Outpatient Program (IOP)?
An intensive outpatient program balances structure with flexibility, making it a good option for individuals who require significant mental health support but don’t need the close monitoring PHPs or inpatient care provide. Those receiving this level of support typically attend therapy and treatment sessions for about 15 hours per week, usually spread across 3 days. This lets participants live at home and maintain daily routines such as work, school and family responsibilities while receiving ongoing care and support.
IOPs combine a variety of therapeutic approaches, including one-on-one counseling, support groups and education on addiction and mental health. The goal of treatment is to help the person return to normal life while still getting the guidance they need to avoid relapse. Individuals gain practical skills for managing cravings, triggers and stressors, all within a supportive group setting and a format that fits their lifestyle.
Key Differences Between PHP and IOP
The main differences between PHPs and IOPs lie in their intensity, time commitment and level of medical support provided. PHPs typically involve 25–30 hours of treatment each week, with structured days similar to the full-time schedule individuals may have in inpatient treatment. They also include more comprehensive medical monitoring, making PHPs suitable for those who need close observation but aren’t candidates for inpatient care.
In contrast, IOPs typically include about 15 hours of treatment each week, spread over fewer days. This makes them a more flexible option for those balancing recovery with work or school obligations or family life.
While both PHPs and IOPs include one-on-one and group therapy, PHPs are more intensive, while IOPs allow for greater freedom.
Who Each Level of Care Is Best For
PHPs are ideal for people experiencing more acute symptoms that require daily monitoring and medical oversight but who are stable enough to live at home. This format is especially beneficial for those who have completed an inpatient treatment program but are still at an increased relapse risk. It’s also appropriate for those facing challenges such as co-occurring mental health disorders, recent relapse or medication adjustments. PHPs provide a structured environment for managing these situations while supporting continued progress.
IOPs, on the other hand, are beneficial for those who’ve achieved some stability in their recovery journey. The individual receives continued support, but they don’t need daily supervision or a high degree of structure. In many cases, people use this level as a step down from PHP or inpatient care. In others, it serves as a starting point for those who have less severe mental illnesses or substance use disorders.
Benefits of Structured Outpatient Care in Recovery
Like inpatient treatment, structured outpatient care provides a supportive approach that helps individuals learn to manage mental illnesses or addiction and achieve long-term recovery. However, it also offers flexibility, making it ideal for those who can’t pause work, school or family responsibilities for an inpatient treatment program. Through regular therapy sessions, medical oversight and peer support, PHPs and IOPs create a consistent framework for healing without isolating individuals from their everyday lives. They’re also more budget-friendly options than inpatient care, making them more accessible for many.
Outpatient care creates an environment that encourages accountability and skill-building, helping individuals gain the tools they need to cope with stressors, manage triggers and avoid relapse. It blends individual and group counseling sessions to allow for personal connections and reduce the feelings of isolation that often accompany rehab.
Additionally, outpatient care lets participants stay connected with family, work and their community, which can be important for long-term success. Overall, these structured programs balance intensive, personalized treatment with real-world engagement, helping the individual learn how to achieve wellness in their home environment.
How to Choose Between PHP and IOP
Choosing a PHP vs. IOP comes down to your personal needs and goals, the stage of recovery you’re in and your personal responsibilities. If you require close medical monitoring, supervision and structured daily support or are transitioning from inpatient care, a PHP may be the best fit.
On the other hand, if you’re stable in your recovery and need flexibility to balance work, school or family responsibilities with treatment, an IOP may be a better option. Talking to a treatment professional can help you assess your situation and needs and choose the level of care that aligns with your lifestyle and goals.
