Understanding IOP
IOP vs. PHP vs. Weekly Therapy: What's the Difference?
If you've been searching for help and run into terms like "IOP" and "PHP," you're not alone. These acronyms describe different levels of care — and the difference between them really matters when you're trying to figure out what you (or your teen, or your partner) actually need.
The four levels of mental health care
Think of it as a ladder. Each step adds more support.
Outpatient therapy — about 1 hour a week
Traditional weekly therapy. Good for ongoing growth, mild to moderate symptoms, or maintenance once you're stable. If you're sleeping, working, and your relationships are okay, this is often enough.
IOP — 9 to 15 hours a week
Intensive Outpatient Program. Three days a week, three hours a day, plus weekly individual therapy. You sleep at home, keep your job or school, and still get serious structured care. IOP is built for the gap between "weekly therapy isn't enough" and "I need to be in a hospital."
PHP — 25+ hours a week
Partial Hospitalization Program. Like a full-time job's worth of treatment. You still sleep at home, but most of your day is treatment. Good for people who need a lot of support but don't need 24/7 supervision.
Inpatient — 24/7
You live at the hospital or facility. This level exists for safety — when you can't keep yourself safe, when withdrawal needs medical management, when you need round-the-clock care.
How to know which one you need
A few honest questions: Is weekly therapy moving the needle? Are you sleeping? Can you make it through a workday? Is your team — therapist, doctor, family — telling you something has to change? If weekly isn't enough but you're not in crisis, IOP is usually the right answer.
Where Dixon fits
Dixon offers a Joint Commission accredited virtual IOP for trauma and depression — for teens and adults across California. We're the step that should have existed for so many people who told us weekly wasn't working.
