The short answer

How Long Is IOP at Exist?

IOP (intensive outpatient) at Exist is about three hours a day, at least three days a week and up to five, at our clinic in Laguna Beach. How long IOP lasts depends on your goals and how you're doing, and it usually runs one to four months. We check in on your progress as you go, so you get the right amount of support for as long as you need it.

The schedule is set, and the number of weeks depends on how you're doing.

What to Expect in PHP and IOP Each Week

Both programs run at the same clinic in Laguna Beach. PHP is about six hours a day and IOP is about three, and either way you go home or back to the Truth House each evening.

  1. A person sitting on a sandstone bench in a quiet coastal garden in soft afternoon haze, back to camera, a canvas bag beside them and a pale sun over the Pacific.

    IOP

    About three hours a day, three to five days a week. Each treatment day has two group sessions, and through the week you meet your therapist and case manager.

  2. A long dark walnut table set simply for lunch with plain plates and water glasses in a cream plaster room, a tall window with a pale sun over the ocean.

    PHP

    About six hours a day, Monday through Friday, with breaks and lunch scheduled. Each day has four group sessions, plus time with your therapist through the week.

  3. A small cream house on a Laguna hillside at blue hour with one warm lit window, a person at the front door with back to camera.

    Evenings

    You go home, or back to the Truth House in Laguna Canyon, each evening and on weekends, so you can use what you learned in real life.

  4. A person standing where a coastal bluff trail splits into two paths at dusk, back to camera, both paths leading toward a huge pale sun.

    We regularly check how you're doing, and we talk with you about stepping up or down as your needs change.

What Decides How Long IOP Lasts

SAMHSA's guide to intensive outpatient treatment for substance use says length should rise or fall with clinical need, support at home, and psychiatric symptoms. We weigh the same things, along with your own goals, when we check in on your progress.

  1. Clinical Need

    How your symptoms respond, with mental health and substance use treated together.

  2. Support at Home

    Whether home is a steady place to go each night, or whether the Truth House would help for now.

  3. The Step-Down Plan

    Some people move from PHP to IOP or weekly 1:1, so your total time in care can include more than one level.

  4. What Your Plan Approves

    Some plans require approval before treatment and ask for proof that each level of care is still needed.
