Interpersonal Psychotherapy (IPT)
Interpersonal Psychotherapy (IPT) is a time-limited psychotherapy developed by Gerald Klerman and Myrna Weissman, manualized in 1984. Its core mechanism: improving interpersonal functioning in one of four problem areas (grief, disputes, transitions, deficits) alleviates depression. This catalogue links it to depression, eating disorders and grief and loss, typically in individual format, short (12-16).

Therapeutic Voice
"It sounds like this grief hasn't had a place to go since your mother died. Let's make room for it here."
View of the Person
A social being whose depression occurs in and is maintained by interpersonal context

Condition-specific assessments
Each conclusion applies to the population and use described. These source-based assessments do not certify the full entry or replace expert clinical review.
Depression & Mood Disorders
Population and scope: Adults with unipolar depression/MDD receiving manual-based interpersonal psychotherapy; separately, people in remission at high risk of relapse or recurrence receiving continuation-phase IPT.
Guideline recommendation
NICE NG222 includes individual, manual-based IPT among treatments for both less and more severe new episodes of adult depression. VA/DoD 2022 weakly suggests IPT among seven unranked psychotherapy options for MDD. It separately weakly suggests a course of IPT, CBT or MBCT after remission for people at high risk of relapse or recurrence, without preferring one of those three. Initial treatment and relapse prevention therefore have different populations and phases. This supports IPT for the stated adult depression contexts, not a universal ranking alongside CBT as the only two leading treatments. The assessment does not cover bipolar depression or interpersonal approaches that do not follow an IPT protocol.

Perinatal Mental Health
Population and scope: Pregnant or breastfeeding adults with mild-to-moderate MDD who are choosing initial psychotherapy; manual-based interpersonal therapy, not generic relationship support.
Guideline recommendation
VA/DoD 2022 strongly recommends offering an evidence-based psychotherapy first for mild-to-moderate MDD during pregnancy or breastfeeding, and explicitly cross-refers to its therapy list, which includes IPT. The recommendation’s discussion identifies postpartum CBT/IPT evidence and does not prefer one psychotherapy over another. This supports IPT as one named option within that scoped recommendation; the strong rating concerns choosing psychotherapy in this population, not proof that IPT is superior. The recommendation was carried forward from earlier guidance with low evidence confidence. It does not establish efficacy for perinatal anxiety, bipolar depression, postpartum psychosis or every pregnancy/postpartum difficulty. Decisions about established medication treatment remain individualized.

Eating Disorders
Population and scope: Adults with binge-eating disorder, receiving eating-disorder-focused interpersonal therapy individually or in a group.
Guideline recommendation
American Psychiatric Association 2023 statement 15 recommends eating-disorder-focused CBT or interpersonal therapy in individual or group formats (1C: recommendation; low-strength supporting evidence). This assessment is limited to binge-eating disorder and does not imply the same recommendation for anorexia nervosa, bulimia nervosa, or other eating disorders.

- Depression in adults: treatment and management (NG222)
Recommendation for the stated population
IPT is a named adult depression treatment option.
Scope: Adults with depression
- Clinical Practice Guideline for the Treatment of Depression Across Three Age Cohorts
Recommendation for the stated population
APA does not select one adult psychotherapy monotherapy as superior. It includes IPT and specifically recommends IPT or CBT plus a second-generation antidepressant when combined treatment is chosen.
Scope: Adult depressive disorders excluding psychotic depression; bipolar disorder is outside the guideline scope. Initial monotherapy choice or combined treatment.
- Clinical Practice Guideline for Management of PTSD and Acute Stress Disorder
Insufficient evidence for or against
VA/DoD finds insufficient evidence for or against IPT for PTSD. This assessment does not determine its status for other conditions.
Scope: Individual psychotherapy for adults with PTSD.
- Clinical Practice Guideline for the Management of Pregnancy
Recommendation for the stated population
VA/DoD strongly recommends offering IPT for prevention in this at-risk population. Treatment of an existing depressive episode is addressed separately.
Scope: Pregnant patients at risk of perinatal depression; individual or group delivery.
- Clinical Practice Guideline for the Management of Pregnancy
Recommendation for the stated population
VA/DoD strongly recommends IPT for treating perinatal depression.
Scope: Depression during pregnancy or postpartum.
- Clinical Practice Guideline for the Management of Pregnancy
Recommendation for the stated population

Scope: Anxiety symptoms during or after pregnancy.
- Management of Major Depressive Disorder
Recommendation for the stated population
VA/DoD suggests interpersonal therapy among seven unranked psychotherapy options (weak for). Treatment strategy also depends on severity, chronicity, prior response and preference.
Scope: Adults with uncomplicated MDD choosing psychotherapy.
- Management of Major Depressive Disorder
Discussed in the source
VA/DoD strongly recommends first-line evidence-based psychotherapy, referring to the list that includes interpersonal therapy. This is a class-level recommendation, with no preferred individual approach.
Scope: Pregnant or breastfeeding adults with mild-to-moderate MDD.

Scope: Remitted MDD with high risk of relapse or recurrence.
- Management of Bipolar Disorder
Discussed in the source
VA/DoD suggests interpersonal and social rhythm therapy alongside medication (weak for). That combined protocol is distinct from IPT alone.
Scope: Adults with bipolar I or II who are not acutely manic.
- Clinical Practice Guideline for the Treatment of Posttraumatic Stress Disorder in Adults
Insufficient evidence for or against
APA finds insufficient evidence to recommend for or against IPT in this comparison.
Scope: Adults with PTSD; IPT versus no intervention or usual care.
- Clinical Practice Guideline for the Treatment of Depression Across Three Age Cohorts

Equity & Cultural Adaptations
Clinical cautions and blind spots
Assessment and precautions
Active psychosis, severe personality disorders requiring longer-term treatment, situations where interpersonal focus does not match the primary clinical presentation (e.g., OCD)
Blind spots
Focused scope (4 problem areas) may miss broader personality patterns; less suited for complex or chronic presentations
Philosophical roots
Sullivan (interpersonal psychiatry: personality is the pattern of interpersonal situations); Meyer (psychobiology); Durkheim (social integration and anomie); Bowlby (attachment/loss)
Origins & Influences
Interpersonal Therapy was developed by Gerald Klerman and Myrna Weissman in the 1970s, originally not as a treatment but as a control condition: they needed a standardized therapy to compare against medication in a clinical trial for depression. They built it on Harry Stack Sullivan's interpersonal theory (personality is the pattern of interpersonal situations), Adolf Meyer's psychobiological model (illness occurs at the intersection of biology and social context), and John Bowlby's attachment theory. The result was deliberately atheoretical about the causes of depression (IPT doesn't claim to know why someone is depressed) but highly specific about the interpersonal contexts in which depression occurs: grief, role disputes, role transitions, and interpersonal deficits. That pragmatism made IPT unusually portable. Because it doesn't require belief in any particular theory of mind, it has been successfully adapted across cultures and settings where Western psychological frameworks don't translate well. The irony of IPT is that a therapy designed as a control condition turned out to be one of the most effective treatments for depression, with WHO endorsement and strong evidence across diverse populations.
