Cognitive-Behavioral Therapy for Disruptive Mood Dysregulation Disorder: A Randomized Control Trial

Area of Science:

• Child and Adolescent Psychiatry
• Clinical Psychology
• Behavioral Therapy

Background:

• Disruptive mood dysregulation disorder (DMDD) is prevalent in child mental health clinics.
• Persistent DMDD symptoms lead to significant functional impairment and adverse outcomes.
• Evidence-based psychotherapeutic interventions for DMDD are limited.

Purpose of the Study:

• To evaluate the effectiveness of cognitive-behavioral therapy (CBT) for children diagnosed with DMDD.

Main Methods:

• Fifty-three children with DMDD were randomized into a CBT group or a wait-list control group.
• The CBT group received 15 weekly individual therapy sessions.
• Symptom assessments were conducted pre-treatment, post-treatment, and at a 3-month follow-up by children, parents, and teachers.

Main Results:

• ANCOVA revealed significant differences between groups in irritability, aggression, and internalizing/externalizing problems.
• Children receiving CBT demonstrated reduced aggressive behavior, anger outbursts, and irritability compared to the control group.
• Symptom improvements in the CBT group were sustained at follow-up.

Conclusions:

• Cognitive-behavioral therapy (CBT) is an effective treatment for improving anger, aggression, and irritability in children with DMDD.
• CBT offers a suitable therapeutic approach for managing DMDD symptoms.
• Sustained symptom reduction supports the long-term benefits of CBT for DMDD.
