An IOP is not better or worse than a PHP. The two forms of treatment are similar except in terms of time commitment. Most intensive outpatient programs schedule 3 to 4 hours of therapy sessions on three to five weekdays. Most partial hospitalization programs, by contrast, schedule 5 to 6 hours of therapy sessions on all five weekdays. An IOP places more focus on group counseling and less on the active monitoring and supervision of symptoms or medications. IOPs are ideal for those who do not need residential rehab, and for those with mild to moderate alcohol use disorders or substance use disorders.
