Predictors and Moderators of Panic Disorder: Cognitive Behavioral Therapy vs. Acceptance and Commitment Therapy

Area of Science:

• Psychology
• Clinical Psychology
• Psychotherapy Research

Background:

• Understanding factors influencing therapy outcomes is crucial for improving interventions and reducing healthcare costs.
• Predictors and moderators of treatment success in panic disorder require further investigation.
• Cognitive Behavioral Therapy (CBT) and Acceptance and Commitment Therapy (ACT) are common treatments for panic disorder.

Purpose of the Study:

• To examine potential predictors and moderators of treatment outcomes in Cognitive Behavioral Therapy (CBT) and Acceptance and Commitment Therapy (ACT).
• To identify patient characteristics such as age, gender, duration of panic disorder, motivation, conscientiousness, and experiential avoidance that may influence therapy effectiveness.

Main Methods:

• Eighty participants diagnosed with panic disorder (56 women, 24 men; average age 38) received 12 group sessions of either CBT or ACT.
• Participants were assessed using multiple measures at pre-treatment, post-treatment, and 3-month follow-up.

Main Results:

• CBT was more effective for older individuals, men, and those with shorter panic disorder duration.
• ACT showed greater efficacy in younger individuals, women, and those with longer panic disorder duration.
• Older subjects, women, those with long panic disorder duration, individuals in the contemplation stage, and those with high experiential avoidance showed the most significant improvements in both therapies.

Conclusions:

• Predictors and moderators of CBT and ACT effectiveness for panic disorder appear to exist.
• Personalizing treatment strategies by considering these variables may enhance therapeutic outcomes for individuals with panic disorder.
