Most people start therapy once a week, and that is how many structured treatments are designed. Many focused therapies last around three months, while long-standing or complex problems can take a year or more. There is no universal number, so the most useful step is to agree on a plan with your therapist and a date to review it.
Part of our guide: Which Type of Therapy Is Right for You?
Research offers a helpful surprise: for depression, how close together sessions are may matter more than the total number of sessions. Many people who respond also do so within a fairly small number of visits, and they often stop once things feel good enough.
If you are having thoughts of suicide or self-harm right now, call or text 988 (988 Suicide & Crisis Lifeline), call 911 or go to the nearest ER. Weekly therapy is not a crisis service, so if your safety is in question, do not wait for your next session.
Typical courses for specific therapies
These are usual ranges from public health agencies and major trials. Your own course may be different.
| Treatment | Usual schedule |
|---|---|
| PTSD: cognitive processing therapy | Usually 12 weekly sessions, about 3 months |
| PTSD: prolonged exposure | Usually 8 to 15 weekly sessions, about 3 months |
| PTSD: EMDR | About 3 months of weekly 50- to 90-minute sessions |
| CBT for depression and anxiety in routine care | 95% of those who responded did so within 14 sessions of higher-intensity CBT; social anxiety, PTSD and OCD often needed longer courses (6 to 16 sessions) |
| Trauma-focused CBT for children and teens | Improvement reported in 8 to 25 sessions |
| Standard DBT | Trials ran 1 year in adults at high suicide risk and 6 months in teens. A 2026 review refers to a traditional 12-month program and also to briefer versions |
| Short-term psychodynamic therapy | 40 hours or fewer in total in the Cochrane review |
| Long-term psychodynamic therapy | At least a year or 50 sessions in research |
Note that some of these figures come from research protocols, and everyday care tends to be more flexible.
What research says about frequency
More often may work better at the start, especially for depression
- A 2013 analysis of 70 studies of therapy for depression found only a small link between total sessions and results, and that link faded after adjusting for other study features. Sessions per week had a stronger link.
- A 2024 analysis of 176 studies found the same strong link between weekly frequency and results, but it was no longer significant after controlling for study characteristics. The authors stress that these findings are correlational.
- A randomized trial of 200 adults in the Netherlands is stronger evidence. With treatment capped at 20 sessions, twice-weekly CBT or interpersonal therapy for depression reduced symptoms more than once-weekly sessions at month 6, with fewer dropouts. The rate of response was also higher, though that result was statistically borderline.
Taken together, this suggests that concentrating sessions may help, at least for depression, and the case is not closed. Twice-weekly therapy also costs more per week and takes more time each week, and it is not realistic for everyone. Ask your clinician whether a stronger start would make sense and what is possible.
Every other week can work, with trade-offs
A study at a university counseling center compared people attending roughly weekly or every other week, in a sample with 3 to 10 sessions. Weekly therapy brought higher chances of early improvement, but it also showed greater deterioration among the small group who got worse before they got better. The authors concluded that frequency should be adjusted individually. This was an observational study in students, so it does not prove cause and effect, and it may not apply to your situation.
The right frequency can change over time
A common pattern is more frequent sessions at the start, when you are building skills or trust, and less frequent sessions as things stabilize. That pattern is reasonable, but strong trial evidence on the best way to taper is limited. Treat it as a decision to make with your therapist. If symptoms are getting worse or life gets harder, it is fine to ask to go back to a closer schedule.
What research says about length
- Many people need less than they fear. In a dataset of over 100,000 patients, most people who responded to CBT did so within the first 14 sessions of higher-intensity care. These data cover people who responded, and not everyone does.
- People often stop when they have improved enough. A study of 1,868 clients with planned endings who attended 1 to 12 sessions, found that the rate of reliable improvement did not rise with sessions attended. The authors suggest that people tend to finish when they reach a "good enough" level. So a longer course is not automatically a better one.
- Longer care may be important for some problems. For chronic conditions and personality disorders, some researchers argue that short-term therapy is not sufficient for many people. This comes from a group that studies long-term psychodynamic work and is debated, but it fits what many clinicians see with long-standing difficulties.
- Length alone does not predict results. The 2024 depression analysis found no link between effect size and number of sessions or total contact time. Researchers still call for work on which patients need which number of sessions.
What might point to more or less therapy
These are practical signs to discuss with your therapist. They are not rules.
Consider more frequent sessions or more support if:
- your symptoms are severe or getting worse
- you are starting trauma-focused or exposure work that is meant to run weekly
- you lose momentum between sessions or forget what you worked on
- weekly therapy is not keeping you safe, in which case you may need a higher level of care
Consider less frequent sessions if:
- you have met your main goals and are using your skills without much prompting
- you run out of things to work on, or sessions feel like catching up
- you are coping well through normal stress
Long, stable stretches of less frequent visits can be fine. If you are thinking of stopping altogether, see how to know when you are ready to end therapy.
How to set a plan with your therapist
- Ask at the start. NIMH suggests asking whether the therapist recommends a specific time frame or number of sessions, how progress will be assessed, and what happens if you are not improving.
- Define what "better" means. Pick a few concrete signs, such as sleeping through the night or going back to a class you had dropped. Our article on how therapy goals are set and measured can help.
- Set a review date. Agree to step back after a set period, for example 8 to 12 sessions, and ask what is working. This is a common-sense checkpoint, not a clinical rule.
- Be honest about what you can sustain. Tell your therapist about your budget, work schedule and childcare. A plan you can keep up beats an ideal one you drop. Some people also find giving honest feedback changes the plan for the better.
- Plan the ending. Ending well often means a tapering schedule and a plan for what to do if symptoms come back. See making CBT changes last for one example.
If you have been in therapy for what feels like a reasonable time and are not getting better, NIMH advises talking to your therapist and considering other professionals or approaches. It may be that you need a different therapy, more frequent sessions or medication, which should always be decided with a prescriber. Our article What to Do If Therapy Isn't Working goes further.
Cost and scheduling
Frequency affects cost, so it helps to talk about money early. Mind Body Seven is an out-of-network practice, and it does not accept Medicare or Medicaid, including managed Medicaid. For many clients with Cigna, Aetna or BCBS plans it files out-of-network claims, and superbills are available in the patient portal for other carriers such as UnitedHealthcare. A Good Faith Estimate is available on request.
To talk through a schedule that fits, see individual therapy or fees and insurance. The intake team can confirm fit, scheduling and costs when you request a consultation.
FAQs
Is every other week enough?
It can be, especially once you are stable or for ongoing support. For intensive work such as trauma treatment, the usual protocols are weekly. Discuss what your goal needs and what you can realistically keep up.
Can I have sessions more than once a week?
Some treatments and some people benefit from a stronger start. Ask your clinician whether it would help you, and ask the intake team what is possible, since scheduling and costs vary.
How long is a therapy session?
It depends on the therapy and clinician. VA figures for PTSD treatments range from about 50 to 90 minutes, and many other therapy sessions fall in a similar range or shorter. Ask for the length up front, since it can also affect billing.
Should my teen go as often as an adult?
Not necessarily. Teens may need more family involvement or a different schedule, and some need more than weekly care. A clinician who treats adolescents can advise on what fits your teen.
