Abstract
Background: Mood disorders, particularly major depressive disorder (MDD), are associated with disruptions in circadian rhythms and interpersonal functioning. Interpersonal and Social Rhythm Therapy (IPSRT), developed by Ellen Frank, integrates interpersonal psychotherapy with behavioural rhythm stabilization and has shown promise in treating mood disorders.
Objective: The present study aimed to evaluate the effectiveness of IPSRT in reducing depressive symptoms and improving interpersonal functioning.
Methods: A quasi-experimental pre–post control group design was employed. A total of 48 participants were divided into an experimental group (n = 24) receiving IPSRT and a control group (n = 24) receiving no structured intervention. Paired-samples t-tests were used to assess changes in depressive symptoms and interpersonal problems.
Results: The experimental group showed significant reductions across all depressive symptom domains, including sleep disturbance, mood, appetite, decision-making, self-view, suicidal ideation, interest, energy, and agitation (all p < .001). Total depression scores significantly decreased, t(23) = 17.02, p < .001. Interpersonal problem scores also showed significant reductions across most domains (p < .001). In contrast, the control group showed no improvement and, in several domains, significant deterioration.
Conclusion: IPSRT is an effective intervention for reducing depressive symptoms and improving interpersonal functioning. Its combined focus on circadian rhythm stabilization and interpersonal processes makes it a comprehensive treatment approach for mood disorders.
