- 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
VA/DoD weakly suggests psychotherapy, naming IPT as an example, or yoga or both for this 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.
- Management of Major Depressive Disorder
Recommendation for the stated population
VA/DoD suggests IPT during continuation treatment to reduce relapse or recurrence (weak for). CBT, IPT and MBCT are not ranked against one another.
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
Recommendation for the stated population
APA recommends IPT-A as an initial psychotherapy option.
Scope: Adolescents with depressive disorders; the adolescent adaptation IPT-A, excluding psychotic depression.
- Clinical Practice Guideline for the Treatment of Depression Across Three Age Cohorts
Recommendation for the stated population
APA recommends combined treatment, favoring a second-generation antidepressant on tolerability grounds.
Scope: Adults aged 60 or older with MDD; combined medication and IPT versus IPT alone.
- mhGAP: brief structured psychological treatment for depression
Recommendation for the stated population
WHO strongly recommends structured psychological interventions including IPT for this population, based on moderate-certainty evidence.
Scope: Adults with moderate-to-severe depression, within the mhGAP non-specialist-care context.
- Mental Health Gap Action Programme (mhGAP) guideline for mental, neurological and substance use disorders
Recommendation for the stated population
WHO conditionally recommends considering IPT, with low-certainty evidence. The 2023 edition retains the 2015 recommendation because eligible new evidence was insufficient; suitability requires an individual assessment.
Scope: People living with dementia and mild-to-moderate depression.

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.

Grief & Loss
Population and scope: Bereaved adults aged 18–95 with clinically primary complicated grief in the 2016 trial; 16-session CGT added to placebo plus structured clinical management.
Randomized studies
Shear et al. (2016) randomized 395 adults to citalopram or placebo, with or without CGT. At 20 weeks, CGT plus placebo improved grief-response rates compared with placebo plus clinical management. Adding citalopram did not significantly improve the grief-response outcome, although depressive symptoms improved. This was not an IPT comparison. Missing assessments remained a limitation despite statistical adjustment; the sample was predominantly White, female and well educated. The historical complicated-grief criteria are not identical to current PGD criteria. Findings do not grade routine early bereavement, every grief therapy or suicide prevention.

How they work
IPT
Core mechanism: Improving interpersonal functioning in one of four problem areas (grief, disputes, transitions, deficits) alleviates depression
Ontology: Depression occurs in an interpersonal context; improving relationships and social roles improves mood
Prolonged Grief Disorder Treatment (PGDT/CGT)
Core mechanism: Revisiting the death narrative integrates the reality of loss + imaginal conversations transform the continuing bond + restoration goals rebuild engagement with life
Ontology: Prolonged grief as a failure of natural adaptation: the attachment system cannot update to accommodate the permanence of loss, leaving the bereaved stuck between wanting the person back and knowing they are gone

What each assumes — and misses
IPT
Philosophical roots: Sullivan (interpersonal psychiatry: personality is the pattern of interpersonal situations); Meyer (psychobiology); Durkheim (social integration and anomie); Bowlby (attachment/loss)
Blind spots: Focused scope (4 problem areas) may miss broader personality patterns; less suited for complex or chronic presentations
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.
Prolonged Grief Disorder Treatment (PGDT/CGT)
Philosophical roots: Bowlby (attachment); Shear (complicated grief as attachment disorder); Foa (emotional processing applied to grief); Klass & Silverman (continuing bonds); Stroebe & Schut (dual process model, source of the loss-oriented and restoration-oriented halves of the protocol); Worden (task model of mourning); DSM-5-TR nosology
Blind spots: Revisiting exercises may feel coercive for clients whose culture doesn't value explicit grief narration; the highly structured protocol may not suit every grieving style; much less evidence for non-death losses than for bereavement; 16-session format may be insufficient for losses compounded by other traumas; PGD diagnosis itself is debated as potentially pathologizing normal grief
Therapeutic voice: I'd like you to close your eyes and tell me the story of the day he died. Start a little before you knew, and tell it as though it's happening now, in the present tense. We'll go about ten minutes. I'm recording it so you can listen at home, and I'm right here the whole time.
Choosing between them
IPT and Prolonged Grief Disorder Treatment (PGDT/CGT) both sit within the Integrative tradition — they share a worldview about what suffering is and how change happens. Differences are more often about technique and emphasis than about underlying theory.
