An initial assessment involves screening questions and physical exams. Based on the findings of this assessment, the treatment team can personalize a treatment plan for your IOP. During ongoing treatment, you will attend 12 to 15 hours of weekly therapy sessions. Evidence-based treatments for addictions and mental health disorders typically involve medication-assisted treatment and/or psychotherapy (talk therapy). After 12 to 16 weeks of intensive outpatient treatment, you can step down to a regular outpatient program if you are not ready to maintain your recovery without assistance. The best IOPs include aftercare that involves relapse prevention and management strategies, ongoing therapy, and access to an alumni program.
