Interpersonal psychotherapy (IPT) is a brief, attachment-focused psychotherapy that centers on resolving interpersonal problems and symptomatic recovery. It is an empirically supported treatment (EST) that follows a highly structured and time-limited approach and is intended to be completed within 12–16 weeks. IPT is based on the principle that relationships and life events impact mood and that the reverse is also true.[1][2] It was developed by Gerald Klerman and Myrna Weissman for major depression in the 1970s and has since been adapted for other mental disorders.[3] IPT is an empirically validated intervention for depressive disorders, and is more effective when used in combination with psychiatric medications.[4] Along with cognitive behavioral therapy (CBT), IPT is recommended in treatment guidelines as a psychosocial treatment of choice for depression.[5][6]
