How Interpersonal Therapy Treats Eating Disorders

What is interpersonal therapy for an eating disorder?

Interpersonal therapy is a structured talk therapy that treats an eating disorder by improving the relationships and life circumstances around it, rather than targeting eating behaviors head-on. It was first developed for depression and later studied as an outpatient treatment for eating disorders 1Ref 1Fairburn CG, Bailey-Straebler S, Basden S, Doll HA, Jones R, Murphy R, O'Connor ME, Cooper Z (2015).A transdiagnostic comparison of enhanced cognitive behaviour therapy (CBT-E) and interpersonal psychotherapy in the treatment of eating disorders.That interpersonal psychotherapy is an outpatient psychotherapy studied for eating disorders and that, in a randomized comparison, enhanced cognitive behavior therapy (CBT-E) produced higher remission at the end of treatment.. The premise is that disordered eating often takes root during grief, conflict with someone close, deep loneliness, or a difficult change in role, and that repairing those areas can loosen the disorder's grip.

Interpersonal therapy (IPT) is one of several evidence-informed talk therapies, and it sits alongside approaches that work more directly on the eating itself. Which one fits depends on the person, the diagnosis, and what a clinician finds on evaluation.

How does IPT compare with CBT-E?

The largest head-to-head trial compared IPT with enhanced cognitive behavior therapy and found that the enhanced cognitive behavioral therapy approach led to higher rates of remission at the end of treatment 1Ref 1Fairburn CG, Bailey-Straebler S, Basden S, Doll HA, Jones R, Murphy R, O'Connor ME, Cooper Z (2015).A transdiagnostic comparison of enhanced cognitive behaviour therapy (CBT-E) and interpersonal psychotherapy in the treatment of eating disorders.That interpersonal psychotherapy is an outpatient psychotherapy studied for eating disorders and that, in a randomized comparison, enhanced cognitive behavior therapy (CBT-E) produced higher remission at the end of treatment.. Both are legitimate outpatient psychotherapies for adults and older adolescents who are not severely underweight. The difference is where they aim.

• CBT-E works directly on the eating problem itself: the rules around food, the checking, the fear of weight change.
• IPT works on the interpersonal life around the eating: the losses, the disputes, the transitions, the isolation.

For most people, current guidance places a therapy that targets eating directly ahead of IPT 2Ref 2National Institute for Health and Care Excellence (2017).Eating disorders: recognition and treatment (NICE guideline NG69).That specific specialist psychological therapies are recommended as first-line treatment for eating disorders.. IPT is more often the alternative reached for when a first-line therapy has not fit.

Who might IPT suit?

IPT tends to fit someone whose eating disorder is clearly braided into their relationships or a life transition, such as a loss, a move, a strained partnership, or a shift in identity like leaving home. Because it is an outpatient talk therapy, it suits people who are medically stable enough to be treated in that setting. Someone who is not medically stable, or who needs closer monitoring, generally needs a higher level of care first 3Ref 3National Eating Disorders Association (2024).Levels of Care for Eating Disorders.That eating-disorder care is delivered at different levels of intensity, that outpatient therapy suits people who are medically stable, and that care is stepped up or down based on medical and psychiatric stability..

That is why a professional eating disorder evaluation comes before any therapy choice. The evaluation looks at physical health, psychological state, and the person's circumstances, and it is what tells a clinician whether IPT is even the right shape of help.

What does a course of IPT look like?

IPT is time-limited and moves through phases rather than continuing open-endedly. Early sessions map the person's relationships and recent life changes, then pick one or two interpersonal areas to focus on, most often grief, an ongoing dispute, a role transition, or long-standing isolation. The middle phase works on those areas directly. The final phase consolidates what has changed and plans for setbacks.

IPT keeps its attention on the present, not on a deep excavation of the past. Sessions ask what is happening now in the person's relationships and how it connects to their eating, rather than tracing everything back to childhood.

Where does IPT fit in the whole treatment plan?

IPT is one piece of care, not the whole of it. Eating-disorder treatment is usually delivered by a team, which can include a therapist, a medical provider, a psychiatrist, and often a dietitian, because the illness affects body and mind at the same time 4Ref 4National Eating Disorders Association (2024).Eating Disorder Treatment: Types, Process, Insurance.That eating-disorder treatment typically uses a multidisciplinary team combining therapy, medical care, psychiatric care, and nutrition support.. A therapy like IPT sits inside that structure rather than replacing it.

The intensity of care can also change over time. Someone may step up to a more supervised setting if they become less stable, or step down as they steady 3Ref 3National Eating Disorders Association (2024).Levels of Care for Eating Disorders.That eating-disorder care is delivered at different levels of intensity, that outpatient therapy suits people who are medically stable, and that care is stepped up or down based on medical and psychiatric stability.. A single therapy is rarely the entire answer, and other approaches, such as dialectical behavior therapy for eating disorders, may be part of the plan for some people.

When is another therapy the better call?

For adolescents with anorexia or bulimia, guidelines point first to family-based treatment, which places parents in charge of supporting their child's eating, rather than an individual therapy like IPT 5Ref 5Crone C, Fochtmann LJ, Attia E, et al. (American Psychiatric Association) (2023).The American Psychiatric Association Practice Guideline for the Treatment of Patients With Eating Disorders (Fourth Edition).That eating-disorder-focused psychotherapy is recommended and that family-based treatment is recommended for adolescents with anorexia or bulimia.. For many adults, a therapy that works directly on eating remains first-line 1Ref 1Fairburn CG, Bailey-Straebler S, Basden S, Doll HA, Jones R, Murphy R, O'Connor ME, Cooper Z (2015).A transdiagnostic comparison of enhanced cognitive behaviour therapy (CBT-E) and interpersonal psychotherapy in the treatment of eating disorders.That interpersonal psychotherapy is an outpatient psychotherapy studied for eating disorders and that, in a randomized comparison, enhanced cognitive behavior therapy (CBT-E) produced higher remission at the end of treatment.. IPT becomes most useful as an alternative, chosen when a first-line therapy has not fit or when interpersonal difficulty is plainly driving the eating problem.

None of this is a decision to make alone. Eating disorders are serious and treatable, and the right approach is one worked out with a clinician who has evaluated the whole picture 6Ref 6National Institute of Mental Health (2024).Eating Disorders: What You Need to Know.That eating disorders are serious but treatable and that seeking a professional evaluation is the recommended next step.. If eating concerns are affecting someone you love, a professional assessment is the honest next step, whatever therapy eventually follows.
