Affect regulation training reduces symptom severity in depression - A randomized controlled trial.

Area of Science:

• Psychology
• Clinical Psychology
• Psychotherapy Research

Background:

• Deficits in emotion regulation are linked to various mental health disorders.
• General affect-regulation training is a potential transdiagnostic treatment approach.
• The efficacy of Affect Regulation Training (ART) as a standalone treatment for depression requires evaluation.

Purpose of the Study:

• To assess the effectiveness of group-based Affect Regulation Training (ART) for major depressive disorder (MDD).
• To compare ART against a waitlist control (WLC) and a common factors control (CFC).
• To investigate emotion regulation skills as a mediator of treatment outcomes.

Main Methods:

• Randomized controlled trial with 218 individuals diagnosed with MDD.
• Intervention groups: Affect Regulation Training (ART), Waitlist Control (WLC), Common Factors Control (CFC).
• Primary outcome: depressive symptom severity measured by the Hamilton Rating Scale for Depression and Beck Depression Inventory.

Main Results:

• ART significantly reduced depressive symptom severity compared to WLC (d = 0.56).
• ART showed a non-significant trend towards superiority over CFC (d = 0.25).
• Mediation analyses confirmed that improved emotion regulation skills accounted for treatment effects compared to WLC.

Conclusions:

• Affect Regulation Training (ART) is an effective intervention for reducing depressive symptoms.
• Enhancing emotion regulation skills is a crucial mechanism in psychological depression treatment.
• ART shows promise as a transdiagnostic intervention, warranting further research on its cost-effectiveness against disorder-specific treatments.
