Frequently Asked Questions
What is the difference between PHP and IOP at STR Harrisburg?
STR Harrisburg offers two levels of outpatient care.

IOP offers flexible scheduling options, with programming either three or five days per week. Day programming is offered Monday through Friday, and evening programming is available Monday, Tuesday, and Thursday. IOP is designed for those who are stable enough to manage more independence while continuing to build recovery skills.
How long is PHP or IOP at STR Harrisburg?
Length of stay at STR Harrisburg is individualized based on each client’s clinical, medical, and social needs. There is no predetermined timeline — because every person’s journey is unique, treatment continues as long as it is clinically appropriate.

For those using insurance, the duration of care is also subject to insurance approvals.
