What is Interpersonal Psychotherapy & How Does It Work

Interpersonal Psychotherapy (IPT) helps clients understand how their relationships impact their emotional well-being and how their emotions affect their relationships. Unlike other therapeutic modalities, IPT is present-focused and targets the interpersonal issues and conflicts that contribute to distress. IPT reduces mental health symptoms by improving interpersonal functioning (Weissman et. al., 2000).

IPT is currently used to treat other mental health conditions, such as anxiety disorders, eating disorders, and post-traumatic stress disorder (PTSD). Many studies support this evidence-based treatment, and it has become a standard treatment for depression and related conditions (Stuart & Robertson, 2012).

Key Concepts

Mental health symptoms often arise in interpersonal problems, and IPT helps clients improve their relationships or adjust to changes within them, ultimately reducing symptoms (Stuart & Robertson, 2012).

IPT focuses on the following issues:

1. Coping with Interpersonal Conflicts. IPT helps clients recognize how conflict contributes to their mental health symptoms and identify ways to manage and resolve them.

2. Exploring Interpersonal Deficiencies

Isolation or lack of social skills can contribute to problems with forming and maintaining meaningful relationships. IPT allows clients to identify and improve interpersonal skills to build healthier connections.

3. Managing Role Transitions

Life transitions, such as losing a job, becoming a parent, or moving homes, often result in stress and emotional turmoil. IPT helps clients adapt by exploring the emotional impact and developing coping strategies.

4. Navigating Grief and Loss

Loss can trigger or worsen depression, and the structured approach of IPT allows clients to process their grief by addressing unresolved emotions.

IPT Session Structure

IPT is typically a 3–4-month process, although it can be extended depending on the client’s needs. Weekly sessions follow a structured format, beginning with an assessment and continuing with specific, targeted interventions (Stuart & Robertson, 2012).

1. Assessment and Diagnosis Phase

The initial sessions focus on understanding the client's current mental health symptoms, history, and relationships. The therapist conducts a detailed assessment to identify the client’s symptoms and explore how these symptoms relate to their interactions with others. An Interpersonal Inventory is completed, where the therapist thoroughly reviews the client’s relationships.

The therapist assesses:

• Communication style

• Current disputes or conflicts

• Losses, role changes, or life transitions

• Available social support

The therapist and client collaboratively identify the primary focus for treatment, which is typically one of four areas: conflicts, role transitions, grief, or interpersonal deficits.  Establishing this focus early in treatment allows for the development of clear therapeutic goals.

2. Interventions and Skill-Building Phase

Phase two is the bulk of treatment. Structured sessions involve the therapist and client working together to address the interpersonal issue(s) identified during the assessment phase. The therapist actively guides the client, offering psychoeducation, communication skills training, and problem-solving strategies designed for the client’s interpersonal challenges (Lipsitz & Markowitz, 2013).

Depending on the focus area, there are a few ways treatment may proceed:

• If the client’s mental health symptoms are associated with ongoing conflicts with others, the therapist helps the client cope with these conflicts. They might explore communication patterns, teach assertiveness skills, and role-play difficult conversations. The goal is to approach conflict more effectively and reduce its impact on the client's emotional well-being.

• Clients dealing with loss are encouraged to explore their feelings. They learn to express emotions they may have been avoiding. The focus is on acknowledging the loss and helping the client reengage with life.

• If the client struggles with a life transition, the therapist assists them in processing their emotions around change. Tools include re-framing negative thoughts, learning coping mechanisms, and exploring the client’s new role.

• If the client is lonely or has difficulties forming relationships, the therapist supports them in building their social skills. They may learn about their attachment style, explore past relational patterns, and practice ways to initiate and maintain connections.

The therapist will provide psychoeducation to help clients understand the link between their symptoms and relationships. For example, the client may be offered a worksheet about how poor communication fuels conflict, leading to anxiety.

3. Termination and Relapse Prevention Phase

As the end of therapy nears, the focus shifts toward skill integration and preparing for life after therapy. Clients reflect on their progress, reinforcing positive relational and emotional changes (Weissman, Markowitz, & Klerman, 2000). Relapse prevention is emphasized, and a plan is developed for maintaining progress and managing future interpersonal issues. The plan includes:

• early warning signs

• support networks

• practical strategies that worked well in therapy

• communication and problem-solving skills

Clients end therapy with a clear understanding of how their relationships affect their emotional health and a set of resources to manage future challenges.

IPT in Practice

IPT is a collaborative, hands-on, and goal-oriented therapy in which the therapist actively offers suggestions, provides psychoeducation, and guides the client through problem-solving exercises. The following are key techniques used in IPT sessions (Stuart & Robertson, 2012):

• ClarificationTherapists help clients clarify their feelings and thoughts about interpersonal issues. Clarification is the first step toward understanding the problem.

• Role-PlayClients practice difficult conversations in a safe environment. The therapist might play the other person's role in a conflict, allowing the client to practice assertiveness or more effective communication. Role-play helps clients develop empathy.

• Communication AnalysisTherapists review conversations with clients, helping them pinpoint where communication broke down and how they can improve it.

• Support NetworkTherapists help clients identify potential sources of support and strengthen those relationships. This might involve contacting old friends, joining social groups, or improving current relationships.

• Encouragement of AffectClients are encouraged to explore and express their emotions about their interpersonal problems.
