PHP, IOP, and OP are three outpatient levels of care that decrease in intensity as you build stability. Together they form a "step-down" continuum that keeps support in place while you return to daily life.

PHP — Partial Hospitalization Program

The most structured outpatient level: full-day treatment about five days a week. PHP combines individual therapy, group therapy, life skills, and recovery education, while you return home or to sober living each evening. Most people spend 4–12 weeks here.

IOP — Intensive Outpatient Program

As you stabilize, IOP offers continued clinical support with more flexibility — typically 3–5 days a week — so you can begin returning to work, school, and family. It emphasizes relapse prevention and practicing new skills in real life.

OP — Outpatient Program

The lightest level: usually 1–2 days a week. OP keeps you connected to therapy and accountability as you build a healthy, independent, sustainable life in recovery, often for several months.

Why the step-down matters

Recovery isn't a single event — it's a series of steps. Moving gradually from higher to lower intensity keeps a safety net in place while you rebuild your life, which is a big part of why it works.
