Interpersonal therapy (IPT) is a structured, time-limited form of talk therapy that focuses on how relationships and life changes affect your mood, and how your mood in turn affects your relationships. Rather than digging deeply into childhood or reshaping core beliefs, IPT works in the present: it helps you understand and improve the interpersonal situations that are tied to how you feel right now.
It was originally developed for depression and has become one of the better-studied talk therapies. If you are weighing your options, this guide explains what IPT is, what the research supports, what a course of treatment looks like, and how to find a licensed provider.
What interpersonal therapy is
IPT is built on a simple observation: emotional distress often shows up around relationships and transitions. A person may become low after a loss, a move, a divorce, a new baby, a job change, or ongoing conflict with someone close. IPT does not claim that relationships cause every mood problem, but it treats them as a practical, changeable starting point.
Treatment is usually organized around one or two “problem areas”: grief or loss, role transitions (a major life change), interpersonal disputes (ongoing conflict), and interpersonal deficits (difficulty forming or keeping connections). You and your therapist pick the area that fits your situation and focus your work there.
What the research supports
Research supports the use of IPT for depression in adults, and it is one of the therapies commonly listed alongside cognitive behavioral therapy as an evidence-based option. The American Psychological Association and the National Institute of Mental Health (NIMH) describe IPT as an established psychotherapy for depression, and Cochrane reviews have examined it across mood and related conditions.
Researchers have also studied IPT for perinatal (pregnancy-related) depression, some anxiety-related presentations, eating disorders, and adjustment to illness, though the strength of the evidence varies by condition. As with any therapy, results differ from person to person, and IPT is not guaranteed to work for everyone. The best choice depends on your diagnosis, preferences, and other treatments you may be using, which is a conversation to have with a clinician.
What a session looks like
A course of IPT is typically time-limited, often around 12 to 16 weekly sessions of roughly 45 to 60 minutes, though this can be adjusted. Treatment usually moves through three phases:
| Phase | Roughly when | What happens |
|---|---|---|
| Beginning | Sessions 1–3 | Review symptoms and history, connect them to a life event or relationship, and agree on a focus area. |
| Middle | Sessions 4–12 | Work directly on the chosen area: communication, problem-solving, processing a loss, or adjusting to a new role. |
| End | Final sessions | Review progress, plan for setbacks, and consolidate skills you can keep using. |
Sessions are collaborative and focused. Your therapist may ask you to describe recent interactions in detail, practice new ways of communicating, or examine how a transition has changed your daily life. Homework, when used, tends to be practical: noticing patterns, trying a conversation differently, or tracking mood.
How to find a licensed provider
IPT is delivered by licensed mental-health professionals, including clinical psychologists, licensed professional counselors, clinical social workers, and some psychiatric nurses and psychiatrists. When looking for a provider, it is reasonable to ask whether they have training in IPT specifically, since not every therapist practices it.
Good starting points include your primary care clinician for a referral, your health insurer’s directory, and the therapist-finder tools maintained by professional bodies such as the American Psychological Association. Community mental-health centers and university clinics may offer lower-cost options. If you are comparing approaches, our family therapy and acceptance and commitment therapy explainers can help you see how IPT differs from other options.
When to seek help
Consider reaching out to a clinician if low mood, loss of interest, sleep or appetite changes, or difficulty functioning last more than a couple of weeks, or if a relationship problem or life change feels unmanageable. Earlier support tends to make treatment easier.
If you are in crisis—having thoughts of suicide or self-harm, or worried about someone who is—call or text 988 (the Suicide and Crisis Lifeline in the US) or go to your nearest emergency department. IPT and other therapies are for ongoing care, not emergencies.
Frequently asked questions
Is IPT the same as CBT? No. Both are structured and evidence-based, but CBT focuses on thoughts and behaviors, while IPT focuses on relationships and life transitions. Some people do well with either.
How long does IPT take? A typical course is often 12 to 16 weekly sessions, though your clinician may adjust the length.
Do I need medication too? Not necessarily. IPT can be used on its own or alongside medication; that decision is individual and best made with a prescriber.
Can IPT be done online? Many clinicians offer IPT by video. Ask whether telehealth is appropriate for your situation.
Does insurance cover it? Coverage varies. Because IPT is delivered by licensed clinicians, it is often billed like other psychotherapy—check your plan.
Is IPT only for depression? It was developed for depression and is best supported there, but it is being studied for other conditions. A clinician can advise on fit.
