What Makes Interpersonal Psychotherapy (IPT) Unique
IPT is fundamentally distinct from other psychotherapies because it focuses exclusively on the style and effectiveness of current interpersonal interactions and relationships, rather than addressing cognitive distortions (like CBT) or unconscious conflicts (like psychodynamic therapy). 1
Core Distinguishing Features
Focus on Relationships, Not Thoughts
IPT targets how patients interact with others in their immediate social context, not what they think. Unlike CBT, which works to modify automatic thoughts, assumptions, and beliefs that provoke maladaptive behavior, IPT concentrates on improving the quality and patterns of interpersonal relationships. 1
The therapy operates on the premise that interpersonal problems—not cognitive distortions—are the primary drivers of psychiatric symptoms, particularly depression. 2, 3
Four Specific Problem Areas
IPT categorizes all interpersonal difficulties into exactly four domains: grief/loss, interpersonal role disputes, role transitions, and interpersonal deficits. 1, 2 This structured framework distinguishes it from more open-ended approaches.
During initial sessions, the therapist identifies which of these four areas is driving the current episode, and this becomes the exclusive focus of treatment. 2
Time-Limited and Present-Focused Structure
IPT is delivered over 12-16 weekly sessions with a defined beginning, middle, and termination phase. 1 This contrasts with open-ended psychodynamic approaches.
The therapy maintains strict focus on current relationships and recent interpersonal changes (particularly those occurring immediately before symptom onset), rather than exploring childhood experiences or long-standing personality patterns. 1, 2
Therapeutic Mechanisms That Set IPT Apart
Relationship as Context, Not Content
IPT frames psychiatric symptoms within interpersonal distress—viewing depression, for example, as arising from disrupted social support and increased interpersonal stress. 1, 3
The proposed mechanisms of change include enhancing social support, decreasing interpersonal stress, facilitating emotional processing, and improving interpersonal skills—all relationship-based rather than cognition-based interventions. 3
Specific Therapeutic Techniques
IPT uses communication analysis as a primary tool, examining how patients express needs, negotiate conflicts, and maintain relationships. 1, 2 This differs from CBT's focus on thought records and cognitive restructuring.
The therapist employs non-directive and directive exploration, clarification, and encouragement of affect to help patients correlate their relational states with their mood. 2
Frequent telephone contacts with patients are maintained between sessions, and parents/family members are often directly involved in treatment. 1
Clinical Applications and Evidence Base
Validated Across Multiple Populations
IPT was originally developed for adult major depression but has been successfully adapted for adolescents (IPT-A), elderly patients, postpartum depression, bipolar disorder, eating disorders, and anxiety disorders. 2, 4, 5
The American Academy of Child and Adolescent Psychiatry recognizes IPT as more effective than control therapy for depressed adolescents with interpersonal problems. 1
Specific Adolescent Considerations
IPT-A addresses developmentally specific interpersonal issues including separation from parents, conflicts with parental authority, peer pressures, first experiences with death, and development of romantic relationships. 1
The therapy is particularly useful for addressing suicidal behavior as a method of communicating anger, distress, or resolving conflict in adolescents. 1
Important Caveats
IPT was originally developed for nonpsychotic, nonsuicidal depressed patients. Its effectiveness with actively suicidal adolescents depends on the patient's ability to establish a therapeutic alliance and commit to informing the therapist about suicidal preoccupations. 1
The therapy requires patients to have at least some existing interpersonal relationships to work with—it may be less suitable for severely isolated individuals with profound interpersonal deficits. 1
Unlike CBT, which can be applied to anxiety through exposure hierarchies and thought challenging, IPT's interpersonal focus makes it most appropriate when relationship problems are clearly linked to symptom onset. 1
