Learn / IOP vs. PHP: Which Treatment Is Best for You?
Key Points
Can a couple of acronyms help you recover from addiction and mental health conditions? They can, and they’ve been doing it for decades.
Here’s what they mean: IOP is intensive outpatient program; PHP is partial hospitalization program. They’re both outpatient programs and primarily differ in intensity levels and time requirements. Depending on your treatment needs, one may be more effective and convenient.
We’ll explore the differences between IOP and PHP and highlight their benefits to help you decide on your care.
IOPs serve those who don’t need 24/7 care or detox1 for their recovery needs. They typically last 1-3 months with 3+ sessions weekly. Each session lasts a couple of hours and often includes therapy, psychoeducation, and other structured activities to keep you well connected to peer and professional support. You’ll likely receive 1:1 and group therapy; some IOPs offer family therapy too. IOPs also focus on practical tools for recovery, like relapse prevention, building coping tools, and how to navigate triggers.
You can go to IOP as a standalone treatment or as a step-down from residential care, which provides 24/7 monitoring and detox services. IOPs provide structure, community, and the continued treatment that can be vital to long-term recovery. Some programs require continuous drug testing, others don’t. Check with the program you have in mind to see what their participation requirements are.
People in IOPs can work or go to school, since sessions can occur in the morning, afternoons, or evenings, depending on the program’s availability.
PHPs are more intensive than IOPs, but still an outpatient program. You can expect to attend treatment for 5-6 days a week, usually for 5+ hours at a time. PHPs focus on skill-building and honing coping tools through group and 1:1 therapy, plus educational sessions to grow your knowledge of addiction and mental health.
PHPs mimic residential treatment in their intensity, but with the ability to go home after treatment. They’re a great bridge between residential treatment and lower levels of outpatient care, like IOP, or patients can join them as a stand-alone treatment. PHPs often address both substance use disorders and mental health conditions; they may focus on one or the other, or each as a dual-diagnosis.
Those in PHP may have time for part-time jobs, but can expect to spend most of their day in treatment. PHP is commonly called day treatment to highlight this.
PHP is more intensive than IOP. It will likely have a structured day-to-day schedule, similar to residential treatment. IOP primarily offers group therapy with less oversight and structure from staff. Its flexibility generally allows you to pick when you attend treatment, like in the morning, afternoon, or evening, whereas PHP is an all-day commitment.
Because it’s more intensive, PHP typically costs more than IOP. It can better serve someone experiencing severe symptoms of addiction and mental illness with its structure and therapeutic variability.
Someone with more manageable symptoms and recovery experience would likely find an IOP more beneficial and relevant to their needs. They still need support and treatment, but not as structured or intensive as a PHP.
Several factors can help you choose between an IOP or a PHP, like
For example, if you have a severe mental illness or substance use disorder, an unsafe home environment, and struggle to navigate your symptoms on your own, PHP would be a good option for you. PHP can be an even better fit if your insurance covers the program and you have work flexibility (either taking a leave or working 1-2 days weekly).
If your symptoms are more manageable, you feel supported at home, and more confident in your ability to navigate day-to-day life without relapsing, IOP could be a better option. This is especially true if you have less funding available for your care and less time to spend outside work and personal obligations.
Many substance use disorders occur alongside a mental health condition2 like anxiety, depression, or trauma. Attending treatment that doesn’t address these conditions can make it less effective, which is why so many outpatient and residential facilities make sure they do.
Due to their less intensive nature, not every IOP or PHP will focus on mental health conditions as a core component of substance use. They may concentrate solely on relapse prevention skills, addiction education, and learning how to navigate triggers. There’s overlap for mental health recovery, but not a precise focus.
Plenty of IOPs and PHPs do offer either core or co-occurring mental health treatment. They’ll discuss how mental health conditions contribute to or cause addiction, and how managing your mental health can improve your addiction recovery. You may learn more about prescription medications for mental health (like antidepressants), self-care strategies, and habits for keeping your mind and body healthy.
Attending an IOP or PHP can produce markedly better treatment outcomes1. It keeps you connected to treatment and teaches relapse prevention skills, coping tools, and other practical assets for long-term recovery. And since they typically require abstinence, it keeps you sober longer, which can increase the likelihood of long-term recovery3.
Studies found outpatient services like IOP and PHP can even have the same level of effectiveness as residential care1; effectiveness meaning sustained sobriety and reduced symptoms. While IOPs and PHPs won’t fit everyone’s needs and preferences, they offer a hopeful, effective alternative to residential treatment and the time and monetary commitments that come with it.
Choosing an IOP vs PHP is a decision made by you and whomever you count on for support. This could be your primary care physician, therapist, work mentor, parent, sibling, or friend.
Reflect on these questions as you make your decision:
You can also note the specific offerings, amenities, and practical factors of the programs they have in mind. What’s their approach to recovery? Do they solely use 12-Step principles? How will the environment look and feel? Are there any groups specific to your demographic?
Keep notes on what you find and see which program feels like the best fit for you. Remember that either option is a step towards recovery—positive, brave, and uniquely yours.
