Cognitive behavioral therapy for misophonia: A randomized clinical trial

Area of Science:

• Psychiatry
• Clinical Psychology
• Neuroscience

Background:

• Misophonia is a disorder characterized by strong emotional reactions (anger, disgust) to specific sounds.
• Sufferers often avoid triggering situations, leading to social isolation and functional impairment.
• This study presents the first randomized controlled trial (RCT) for misophonia, assessing cognitive behavioral therapy (CBT).

Purpose of the Study:

• To evaluate the short- and long-term efficacy of group-based CBT for misophonia.
• To assess CBT's impact on symptom severity and overall clinical improvement.
• To examine effects on general psychopathology and quality of life.

Main Methods:

• An evaluator-blinded, randomized clinical trial was conducted with 54 misophonia patients.
• Participants were assigned to 3 months of weekly group-CBT or a waiting list.
• Assessments included the Amsterdam Misophonia Scale-Revised (AMISOS-R) and Clinical Global Impression-Improvement (CGI-I) at multiple time points up to 1-year follow-up.

Main Results:

• CBT significantly reduced misophonia symptoms in the short-term (p < .001).
• 37% of the CBT group showed clinical improvement versus 0% in the waiting list group (p < .001).
• The positive effects of CBT were sustained at the 1-year follow-up.

Conclusions:

• This RCT demonstrates the short-term and long-term effectiveness of CBT for misophonia.
• CBT offers a viable treatment option for individuals suffering from misophonia.
• Further research can build upon these findings to optimize misophonia treatment strategies.
