The Efficacy of Interpersonal Psychotherapy (IPT) for Major Depressive Disorder (MDD): A Meta-Analysis of Randomized Controlled Trials
Abstract
Interpersonal Psychotherapy (IPT) has been recognized as an effective intervention for Major Depressive Disorder (MDD), focusing on interpersonal relationships and life events as triggers for depressive episodes. This meta-analysis of randomized controlled trials (RCTs) evaluates the efficacy of IPT in reducing depressive symptoms and improving social functioning in individuals with MDD. Through a comprehensive review of the literature, the meta-analysis synthesizes effect sizes from RCTs assessing the effectiveness of IPT compared to control conditions (e.g., waitlist, medication, other psychotherapies) in targeting symptoms of depression, including sadness, hopelessness, guilt, and interpersonal difficulties. Additionally, it examines potential moderators of treatment outcomes, such as treatment duration, therapist experience, treatment fidelity, and participant characteristics (e.g., age, comorbidities), to better understand the factors influencing the effectiveness of IPT for MDD.
