Interpersonal psychotherapy (IPT) is a structured, evidence-based treatment for depression that focuses on relationships, social functioning, and major life changes. Instead of primarily examining thought patterns, IPT looks at what is happening between you and the people around you — including grief, relationship conflict, loneliness, or a difficult transition. The approach is usually time-limited and goal-oriented, with therapy focused on a specific interpersonal problem connected to your depressive symptoms.
What is interpersonal therapy (IPT)?
Interpersonal therapy is a structured psychotherapy that treats depression by addressing relationship difficulties, social isolation, grief, and major changes in a person’s life. IPT is based on the idea that depression and interpersonal problems can reinforce one another. By improving communication, relationships, and coping with life changes, therapy aims to reduce depressive symptoms and improve day-to-day functioning.
IPT was developed in the 1970s by psychiatrists Gerald Klerman and Myrna Weissman. It was initially developed in the context of research on depression and antidepressant treatment and was subsequently established as a standalone psychotherapy.
The approach is deliberately focused on the present. Your therapist may discuss your history when it helps explain current relationship patterns, but the main focus is on what is happening in your life now.
IPT typically involves identifying one or more of four interpersonal problem areas:
- Grief — difficulties associated with the death of someone important.
- Role disputes — ongoing conflict with another person involving incompatible expectations.
- Role transitions — difficulty adapting to a major change in your social role or circumstances.
- Interpersonal deficits — persistent loneliness, social isolation, or difficulty establishing and maintaining relationships.
The American Psychological Association includes IPT among the recommended psychotherapies for depression in adults. Its clinical practice guideline emphasizes that treatment selection should take into account the available evidence as well as the person’s preferences and circumstances.
IPT is generally structured rather than open-ended. The exact number of sessions varies, but a course may involve around 12–16 sessions, while the APA notes an average of 16–20 weekly sessions for adults receiving IPT.
What are the four problem areas in interpersonal therapy?
IPT organizes treatment around four interpersonal problem areas: grief, role disputes, role transitions, and interpersonal deficits. Your therapist identifies the most relevant area by examining your current relationships and recent life events. The goal is not to label your entire life with one category, but to identify a specific interpersonal situation that can become the focus of treatment.
1. Grief
In IPT, grief becomes a treatment focus when the death of someone close is connected with the onset or continuation of depressive symptoms.
Therapy may involve:
- processing the loss and associated emotions;
- understanding how the loss has changed your daily life;
- identifying changes in your social support;
- rebuilding relationships and routines;
- adjusting to life without the person who died.
For example, someone who lost a parent and gradually became socially isolated may work with their therapist on both the experience of loss and the interpersonal consequences that followed.
2. Role disputes
Role disputes involve significant relationships in which two people have different expectations of one another.
This might involve:
- conflict with a partner;
- repeated disagreements with a family member;
- difficulties with a friend;
- conflict with a colleague or manager;
- uncertainty about expectations within an important relationship.
The purpose of IPT is not to determine who is right. Instead, therapy focuses on understanding the disagreement, improving communication, clarifying expectations, and considering possible ways forward.
3. Role transitions
A role transition occurs when an important part of your life changes and you need to adapt to a new social or personal role.
Examples include:
- starting or leaving a job;
- receiving a promotion;
- becoming a parent;
- getting divorced or separated;
- moving to another city;
- retiring;
- experiencing a significant change in physical health;
- moving from one stage of education or work to another.
These changes can affect both your identity and your relationships. IPT helps you understand what has been lost, what has changed, what new demands you face, and what sources of support are available.
4. Interpersonal deficits
Interpersonal deficits are relevant when chronic loneliness, social isolation, or difficulty maintaining relationships is closely connected with depression.
Treatment may focus on:
- identifying recurring interpersonal patterns;
- understanding difficulties in communication;
- developing more effective ways of expressing needs;
- increasing social connection;
- practicing new ways of responding to other people.
The four-area framework is a defining feature of IPT and helps keep treatment focused on a specific interpersonal problem rather than treating depression as an entirely abstract symptom.
How effective is interpersonal therapy for depression?
Research supports IPT as an effective treatment for depression, although it is not established as universally superior to other evidence-based psychotherapies.
The American Psychological Association recommends IPT among the psychotherapies that clinicians may offer for adult depression.
Treatment response depends on factors including the nature and severity of depression, other mental health conditions, treatment engagement, therapeutic relationship, and whether the therapy addresses the problems contributing to the person’s symptoms.
How is IPT different from CBT?
IPT and CBT are both structured, evidence-based psychotherapies for depression, but they emphasize different aspects of a person’s experience. CBT focuses more directly on relationships between thoughts, emotions, and behaviors, while IPT focuses on interpersonal relationships, social functioning, grief, and major life transitions. Neither approach is considered universally better for every person.
A simplified comparison looks like this:
- IPT: focuses on relationships, communication, grief, role changes, and social functioning.
- CBT: focuses on unhelpful thought patterns, emotions, and behaviors.
- IPT: asks how current relationships and life circumstances are connected with depression.
- CBT: asks how patterns of thinking and behavior may be maintaining depressive symptoms.
- IPT: may be particularly relevant when a loss, conflict, transition, or social isolation is closely connected with the depressive episode.
- CBT: may be particularly relevant when unhelpful thinking and behavioral patterns are prominent treatment targets.
For example, imagine someone experiencing depression after a divorce. In IPT, therapy may focus on the transition from being married to being single, changes in social relationships, grief associated with the end of the relationship, and rebuilding support. In CBT, treatment might focus more directly on thoughts such as “I will always be alone” and behaviors such as social withdrawal.
There is no requirement to choose a therapy based solely on its label. A therapist can help assess which approach fits your symptoms, circumstances, preferences, and treatment goals.
What happens during an interpersonal therapy session?
IPT usually begins with an assessment of your depressive symptoms, relationships, recent life events, and social functioning. The therapist and client then identify a central interpersonal problem and establish concrete goals. Later sessions focus on working directly with that problem through discussion, communication strategies, problem-solving, and sometimes role-play. The final phase focuses on consolidating progress and preparing for the end of treatment.
Early sessions
The first sessions are typically used to understand:
- your depressive symptoms;
- important current relationships;
- recent changes or losses;
- sources of social support;
- interpersonal conflicts;
- changes in your social role;
- the connection between these experiences and your depression.
This process is sometimes described as an interpersonal inventory.
The therapist and client then agree on the main problem area that will guide treatment.
Middle sessions
The middle phase is the active working stage of IPT.
You may discuss situations that happened during the previous week and examine how you responded. Depending on the treatment focus, you might work on:
- expressing your needs more clearly;
- handling conflict;
- communicating difficult emotions;
- rebuilding social connections;
- adapting to a new role;
- processing a significant loss;
- identifying and changing unhelpful interpersonal patterns.
Role-play may be used to rehearse a difficult conversation before you have it in real life.
Final sessions
The final stage focuses on reviewing what has changed and preparing for the end of therapy.
IPT gives particular attention to the ending of treatment because endings themselves can involve feelings of loss, uncertainty, or transition. These experiences can provide an opportunity to apply the skills and insights developed during therapy.
Can interpersonal therapy be done online?
Yes. IPT can be adapted for remote treatment, including therapist-supported internet treatment and telehealth sessions. Research has found that IPT delivered remotely can reduce depressive symptoms, although the evidence varies by delivery format and study design. Online treatment should therefore be viewed as an evidence-supported option rather than assumed to be identical to every form of in-person IPT.
For someone considering online therapy, practical factors can include:
- whether the therapist has specific training in IPT;
- whether sessions are live video sessions or a self-guided program;
- whether the treatment is structured around the IPT protocol;
- whether the therapist is licensed to provide services where you are located;
- whether your insurance covers telehealth;
- whether you have enough privacy for sessions at home.
Who might benefit from interpersonal therapy?
IPT has its strongest evidence base in depression, particularly unipolar depressive disorders. It may be especially relevant when depressive symptoms are closely connected with a significant loss, relationship conflict, major life transition, or persistent social isolation. IPT has also been adapted for different populations and conditions, but the strength of evidence varies across these applications.
IPT may be worth discussing with a therapist if:
- your depression began or worsened after a major relationship change;
- you are struggling after the death of someone close;
- a conflict with someone important is affecting your emotional health;
- you have recently entered a new life role and are finding it difficult to adapt;
- you feel increasingly isolated from other people;
- depression has made it harder to maintain relationships;
- you want a structured and time-limited form of psychotherapy.
IPT has also been adapted for adolescents and has been studied for conditions beyond depression, including some anxiety disorders, eating disorders, and perinatal mood disorders. However, evidence for these applications is not as extensive as the evidence supporting IPT for depression.
If symptoms are severe, involve psychosis, suicidal thoughts, significant substance use, or another condition requiring urgent or specialized care, a broader clinical assessment may be necessary. IPT can be part of treatment, but the appropriate level and type of care depends on the individual’s clinical situation.
Can IPT help with depression after a major life change?
Yes. Major life changes are one of the central situations addressed by IPT because they can alter both a person’s identity and their relationships. Role transitions such as starting a new job, becoming a parent, moving, divorce, retirement, or a major health change can create losses and new interpersonal demands that contribute to depressive symptoms.
The therapist may help you examine:
- what changed;
- what you lost as a result of the transition;
- which relationships have changed;
- what new expectations you are facing;
- which sources of support remain available;
- what new relationships or routines need to be developed.
This makes IPT potentially relevant to depression that emerges during periods of substantial social or personal change.
Frequently Asked Questions
How long does interpersonal therapy (IPT) take?
IPT is usually a time-limited treatment. Many protocols use approximately 12–16 sessions, while the APA reports an average of 16–20 weekly sessions for adults. The actual length depends on the treatment plan, clinical needs, and the specific IPT format being used.
Is IPT covered by insurance in the US?
Insurance coverage for IPT depends on your specific health plan, therapist, location, and mental health benefits. The fact that IPT is an evidence-based psychotherapy does not by itself guarantee reimbursement. Before starting treatment, check whether the therapist is in-network and whether your plan covers outpatient psychotherapy and telehealth services.
What’s the difference between IPT and CBT for depression?
CBT primarily targets patterns of thinking and behavior associated with depression, while IPT focuses on relationships, communication, grief, social functioning, and major life transitions. Both are evidence-based treatments for depression, and research does not establish one of them as universally more effective than the other.
Can IPT be done online or through telehealth?
Yes. IPT has been adapted for telehealth and internet-based delivery. Research supports the potential effectiveness of remote IPT, although results depend on the format, level of therapist support, patient population, and study design.
Does interpersonal therapy work for anxiety?
IPT was originally developed primarily for depression, and that remains its strongest evidence base. It has also been adapted and studied for some anxiety-related conditions, but the evidence is more limited than it is for depression. A therapist can assess whether an interpersonal approach makes sense for your particular symptoms and treatment goals.
How do I find a therapist trained in IPT?
Look for a therapist who specifically identifies interpersonal psychotherapy as a treatment approach and ask about their training in the IPT model. Because simply listing “interpersonal therapy” does not necessarily indicate formal IPT training, it can be useful to ask whether the therapist follows a structured IPT protocol and which population they primarily use it with.
Is IPT effective for postpartum depression?
IPT has research support for postpartum depression. For postpartum depression, treatment decisions should take into account symptom severity, individual preferences, breastfeeding or pregnancy status where relevant, medical history, and whether medication or combined treatment may also be appropriate.

If you are experiencing depression, loneliness, relationship difficulties, grief, or a major life transition, you do not have to determine the right therapy approach on your own. A therapist can help you understand what is contributing to your symptoms and whether IPT or another evidence-based approach fits your situation.
