Interpersonal Therapy (IPT) for Eating Disorders: How Relationships Shape Recovery

Written by Dr. Kait Rosiere, Licensed Psychologist and Eating Disorder Specialist in Orlando, FL

Eating disorders don't develop in a vacuum. They grow in the spaces between us — in the relationships where we learned to cope, to people-please, to shrink, to perform. And they often get worse when those relationships are strained, changing, or painful.

That's where Interpersonal Therapy (IPT) comes in. Unlike approaches that focus mainly on food behaviors or thought patterns, IPT looks at the relational context of eating disorder symptoms. It asks: What is happening in your relationships that might be fueling this disorder?

As an eating disorder therapist in Orlando, I use IPT principles alongside other evidence-based approaches to help clients understand the connection between their relationships and their eating disorder — and to build the interpersonal skills that support recovery.

What Is Interpersonal Therapy (IPT)?

Interpersonal Therapy was originally developed in the 1970s by Gerald Klerman and Myrna Weissman as a treatment for depression. It's based on a simple but powerful idea: mental health symptoms are deeply connected to our relationships. When our relationships are struggling, our mental health tends to struggle too.

IPT doesn't necessarily dig into the past. Instead, it focuses on current interpersonal problems — the relational patterns that are keeping you stuck right now. It's time-limited (usually 12-20 sessions), structured, and goal-oriented.

Over the past two decades, researchers have adapted IPT specifically for eating disorders, and the results have been impressive. A landmark study published in the Archives of General Psychiatry found that IPT was as effective as CBT for treating bulimia nervosa at long-term follow-up. For binge eating disorder, research in Behaviour Research and Therapy showed IPT produced lasting reductions in binge episodes that held up years after treatment ended.

How IPT Works for Eating Disorders

IPT for eating disorders focuses on four main interpersonal problem areas. Your therapist will work with you to identify which ones are most relevant to your situation:

1. Grief and Loss

Unresolved grief doesn't just mean someone died — though it can include that. It can also mean the loss of a relationship, a role, a version of yourself, or a life you expected to have. Many people with eating disorders use food behaviors to numb grief they haven't been able to process.

In IPT, you explore the loss, mourn what was taken, and find new ways to carry that grief that don't involve restricting, binging, or purging.

2. Role Disputes

Role disputes happen when you and someone important in your life have different expectations about your relationship. Maybe your partner wants you to eat "normally" but doesn't understand recovery. Maybe your parents still treat you like a child. Maybe a friend makes comments about your body that trigger you. Maybe it’s unrelated to the eating disorder all together. It could be that you and your partner express love in different languages or have different ideas about who does what around the house.

These conflicts create stress that can directly fuel eating disorder behaviors. IPT helps you understand the dispute, improve communication, and either resolve the conflict or make a decision about the relationship.

3. Role Transitions

Major life changes — starting college, getting married, becoming a parent, losing a job, retiring, moving — are common triggers for eating disorders. These transitions require you to give up one role and take on another, and that shift can feel overwhelming.

IPT helps you grieve the old role, develop skills for the new one, and build a support system that helps you navigate the change without falling back on disordered eating.

4. Interpersonal Deficits

Some people struggle with eating disorders partly because they lack the social skills or relationships they need to cope with life's challenges. They may feel chronically lonely, have difficulty making friends, or struggle to communicate their needs.

IPT addresses this by helping you build communication skills, practice assertiveness, and develop more fulfilling relationships — which reduces the need to turn to food for comfort or control.What Does IPT Look Like in Practice?

IPT typically unfolds in three phases:

Phase 1 (Sessions 1-4): Assessment and Focus
Your therapist will do a thorough assessment of your eating disorder symptoms and your current relationships. Together, you'll create an "interpersonal inventory" — a map of the important people in your life and how those relationships affect your mood and eating behaviors. You'll choose one or two problem areas to focus on.

Phase 2 (Sessions 5-12+): Working Through the Problem
This is where the real work happens. Depending on your focus area, you might practice having difficult conversations, process grief, explore how a life transition is affecting you, or work on building social connections. Your therapist will help you make connections between what's happening in your relationships and what's happening with your eating disorder.

Phase 3 (Final Sessions): Consolidation and Prevention
In the final phase, you review what you've learned, celebrate your progress, and develop a plan for maintaining gains. You'll also identify potential future interpersonal triggers and create strategies for handling them without turning to eating disorder behaviors.

IPT vs. Interpersonal Process Therapy

It's worth noting that Interpersonal Therapy (IPT) is different from Interpersonal Process Therapy, though they share some overlap. IPT is a structured, time-limited treatment that focuses on current relational problems. It teaches fundamental coping skills to address current issues - which is invaluable.

Interpersonal Process Therapy (as described by Edward Teyber) is a broader therapeutic approach that examines how relational patterns from earlier in life show up in current relationships — including the therapy relationship itself. It addresses perpetuating factors that drive eating disorder behaviors.

Both can be valuable in eating disorder treatment. In practice, many therapists integrate elements of both: using IPT's structured focus on current relationships while also paying attention to the deeper relational patterns that Interpersonal Process Therapy highlights. Though Interpersonal Process Therapy has not been researched for eating disorders as extensively as IPT, it addresses something crucial IPT does not — our attachments patterns directly impact how secure we feel in relationships: with ourselves and others.

Where IPT asks “what’s going on in this specific relationship?”
Interpersonal Process looks at longstanding patterns, like “you worry that people are going to pull away from you.”

This is crucial correlation: we know that individuals with eating disorders show significantly more insecure attachment behaviors — and relational difficulties directly influence eating disorders.

Research in attachment theory and relational psychotherapy consistently shows that attachment patterns directly influence emotional regulation, self-worth, and coping strategies. For people with eating disorders, these relational templates can play a powerful role in maintaining symptoms.

At Bloom Psychological Services, we draw from both traditions depending on what serves each client best.

Who Is IPT Best For?

Research supports IPT for several eating disorder presentations:

  • Bulimia nervosa — IPT is considered a first-line treatment, with evidence showing it's as effective as CBT at long-term follow-up

  • Binge eating disorder — Multiple studies show IPT significantly reduces binge frequency and improves interpersonal functioning

  • Eating disorders with significant relational components — If your eating disorder symptoms spike during relationship stress, after conflicts, or during transitions, IPT may be especially helpful

  • People who haven't responded to CBT alone — IPT offers a different angle that can be effective when cognitive-behavioral approaches aren't enough

IPT may be less ideal as a standalone treatment for severe anorexia nervosa that requires medical stabilization, though it can be a valuable component of a comprehensive treatment plan.

The Connection Between Relationships and Eating

If you're wondering why relationships matter so much in eating disorder recovery, consider this: eating disorders are often about unmet emotional needs. When we can't get comfort, connection, validation, or control from our relationships, we look for it in food behaviors. Restriction can feel like control when everything else feels chaotic. Bingeing can fill an emotional void. Purging can feel like releasing unbearable feelings.

IPT addresses the source of that emotional pain — the relationships themselves — rather than just the symptoms. When your relational needs start getting met in healthy ways, the drive to use eating disorder behaviors naturally decreases.

This is why combining IPT with other approaches like DBT (for emotional regulation), EFT (for processing emotions), or IFS (for understanding internal parts) can be so powerful. Each approach addresses a different piece of the puzzle.

Frequently Asked Questions

How long does IPT treatment last?

Traditional IPT is time-limited, usually 12-20 sessions. However, many therapists integrate IPT principles into longer-term treatment, especially when the eating disorder is severe or when multiple interpersonal issues need attention.

Can IPT be combined with other therapies?

Yes. In fact, many eating disorder specialists combine IPT with CBT, DBT, EFT, or other approaches to address both the relational and behavioral aspects of the disorder. This integrated approach often produces the best outcomes.

Is IPT only about romantic relationships?

Not at all. IPT addresses all significant relationships — family, friends, coworkers, romantic partners, and even the relationship with yourself. Any relationship that affects your mood and eating behaviors is fair game.

What if I don't have many relationships?

That's actually one of the four problem areas IPT addresses: interpersonal deficits. If loneliness or social isolation is contributing to your eating disorder, IPT can help you build the connections you need.
