Outpatient Therapy
Weekly or periodic therapy with the lowest level of treatment intensity.
An IOP sits between once-a-week therapy and a full day treatment program. Sessions typically run about three hours, three to five days a week – somewhere between 9 and 15 hours of structured care weekly, depending on the person’s needs and how the program is built.
Each day usually splits between group therapy and individual check-ins, with psychoeducation and skill-building worked into the group portion. That’s different from standard outpatient therapy, where a person might see a therapist for 45 minutes once a week and manage everything else on their own between sessions. IOP gives more contact hours, more consistency, and more chances to practice a skill before the week is over.
For someone stepping down from a partial hospitalization program or inpatient care, IOP is usually the next stop – enough structure to keep progress going, without the full-day commitment.
Behavioral health treatment can range from weekly outpatient therapy to more structured, higher levels of support. Intensive outpatient programming provides meaningful structure while allowing clients to continue living at home.
Weekly or periodic therapy with the lowest level of treatment intensity.
Structured treatment several days per week while clients continue living at home.
More frequent daytime treatment for people who need greater clinical structure.
Around-the-clock support for people who need the highest level of behavioral health care.
Our clinicians see IOP work well for depression, generalized and social anxiety, PTSD and other trauma responses, mood disorders including bipolar disorder, and borderline personality disorder. Emotional dysregulation that’s starting to affect work, school, or relationships is often the underlying thread, regardless of diagnosis.

If more than one of these sounds familiar, it’s worth a conversation with our admissions team rather than trying to guess from a checklist.
The difference between standard outpatient treatment and Intensive outpatient programs for behavioral health lies in the level of care. Standard outpatient treatment typically involves less frequent sessions, often consisting of weekly meetings with a therapist or counselor; it focuses on addressing mental health or substance use issues in a more flexible and less structured manner.

Conversely, IOPs offer a higher level of care, providing several therapy sessions each week. This increased intensity allows participants to engage deeply with their treatment, develop essential coping skills, and receive a comprehensive support system; it also allows them to maintain some aspects of their daily lives, such as work or school.
The biggest difference is time. A partial hospitalization program usually runs five to six hours a day, five days a week – closer to a full-time commitment, aimed at people who need the most support outside of an inpatient setting. IOP asks for less time per day and often fewer days, which makes it a natural next step once the acute crisis has passed but ongoing structure still matters. Some clients move from PHP into IOP as part of one continuous treatment plan; others start directly in IOP if that’s the right entry point.
Standard outpatient therapy is usually one session a week, sometimes every other week once things stabilize. IOP is a different order of intensity: multiple sessions a week, a mix of individual and group formats, and a set schedule that builds momentum rather than relying on a single weekly check-in. People often move to standard outpatient care after finishing an IOP, once the coping strategies they built in the program have had time to take hold in daily life.
The main differences between partial hospitalization programs (PHP) and intensive outpatient programs (IOP) for behavioral health revolve around the following: the level of care, intensity, and daily structure. PHPs provide a higher level of care, typically involving full-day programming several days a week. This structure is ideal for individuals requiring more comprehensive support.
In contrast, IOPs offer a less intensive schedule, usually consisting of several hours of therapy a few days a week; this allows participants to engage in treatment while still managing daily responsibilities, such as work or school. While both PHP and IOP focus on providing structured therapeutic support, PHP is generally suited for individuals needing more intensive treatment; IOP is designed for those who require significant support but can maintain a degree of independence in their daily lives.
Most clients attend three to five days a week, with sessions built around group therapy first, followed by shorter individual check-ins. Groups draw on CBT and DBT skills work – practical tools for managing distress, regulating mood, and handling conflict – rather than lecture-style psychoeducation alone. Our clinicians adjust the mix of group and individual time as a person’s needs shift over the course of the program.
Every client works with an individual therapist alongside the group component; that relationship is where the group work gets applied to a person’s specific situation. Learn more about how individual therapy fits into the broader program. Family sessions are offered when appropriate – not mandatory, but often useful for clients whose home environment plays a role in their recovery.
Some clients attend in person at our Plymouth location; others use our virtual IOP option, which runs the same clinical structure over telehealth. Virtual IOP tends to suit people balancing treatment with a job that doesn’t allow for a commute several days a week, or clients further from Plymouth who’d otherwise go without this level of care.
Most clients stay in IOP for six to twelve weeks. That range moves based on a few factors: how someone responds to the initial weeks of treatment, whether they stepped down from PHP or entered IOP directly, and what their individual treatment plan calls for as goals are met. Some clients taper into fewer sessions per week before finishing, rather than stopping all at once – our clinicians build that step-down into the plan rather than treating the end date as fixed from day one.
Most major insurance plans in Massachusetts recognize IOP as a covered level of care, though what’s covered – and what a client pays out of pocket – depends on the specific plan. The fastest way to get a real answer is to verify your insurance directly; our team can tell you what your plan covers before you commit to anything.

Reaching out starts with a conversation, not a commitment. Here’s what that looks like:
If you or someone you care about is weighing this decision, contact our admissions team – a short call is often enough to know what the next step should be.
PHP is a bigger time commitment – typically five to six hours a day, five days a week – and is built for people who need more support than IOP provides. IOP asks for fewer hours and often fewer days, making it workable alongside a job or school schedule while still providing structured, multi-day treatment.
Most major insurance plans cover IOP as a recognized level of care, but the specifics – copays, session limits, in-network status – vary by plan. Verifying your insurance directly is the most reliable way to know your actual costs before starting.
Yes, for most clients. IOP is designed around that need specifically – sessions run a few hours a day rather than a full day, which is why many people attend while continuing to work or attend school. Virtual IOP is often the better fit for someone whose schedule makes daily travel to Plymouth difficult.
If weekly therapy has kept things stable, it’s probably still the right level of care. IOP tends to make sense when symptoms are escalating despite regular therapy, when someone is stepping down from a higher level of care like PHP, or when a single session a week isn’t providing enough support to prevent a crisis. A clinical assessment can settle the question more precisely than guessing.
