Levels of care

Intensive outpatient (IOP) in Orange County

IOP gives you real treatment, several days a week, while you keep living at home and often keep working or studying.

How IOP works

A typical IOP is about 3 hours a day, 3 to 5 days a week, for 8 to 12 weeks. Most time is spent in small therapy groups, with regular one-on-one sessions. Many Orange County programs offer evening IOP for people who work days.

Who IOP is for

  • People stepping down from residential or PHP
  • People with mild to moderate substance use who are medically stable
  • People who have a safe, sober place to live
  • People who need to keep working or caring for family

What happens in IOP groups

Groups usually have 6 to 12 people and a licensed clinician. Topics include relapse prevention, coping with cravings, stress and emotions, communication, and planning for high-risk situations. Most programs add a weekly individual session and, if needed, medication management.

Questions to ask an IOP

  • How many hours a week, and for how many weeks?
  • Are groups led by licensed clinicians?
  • Do you offer medication-assisted treatment?
  • Is there drug testing, and how often?
  • What happens after IOP ends?

Balancing IOP with work

Many people keep working during evening IOP. You do not have to tell your employer details; if you need schedule changes, job-protected leave under FMLA or the California Family Rights Act may apply. Plan your week around group times, protect your sleep, and tell one person at home your schedule so they can support you.
