Testing Clinical Intuitions About Barriers to Improvement in Cognitive-Behavioral Therapy for Panic Disorder

Area of Science:

• Psychiatry and Psychology
• Clinical Psychology
• Psychotherapy Research

Background:

• Clinical intuition shapes psychotherapy practice and generates research hypotheses.
• Empirical testing of clinicians' beliefs about treatment barriers is crucial.
• Cognitive-behavioral therapy (CBT) is a common treatment for panic disorder.

Purpose of the Study:

• To evaluate whether clinicians' perceived barriers to CBT for panic disorder are empirically supported.
• To investigate factors influencing treatment outcomes in CBT and panic-focused psychodynamic psychotherapy (PFPP).

Main Methods:

• Utilized data from a randomized-controlled trial comparing CBT and PFPP for adults with panic disorder (N=161).
• Assessed panic severity using the Panic Disorder Severity Scale at multiple time points.
• Employed hierarchical linear modeling and moderation analyses to examine predictors of treatment outcome.

Main Results:

• None of the 15 perceived clinician-endorsed barriers predicted poor treatment outcomes.
• Dissociation during panic attacks was unexpectedly associated with greater symptomatic improvement in both CBT and PFPP.
• Patients with PTSD or less severe panic disorder showed more rapid improvement with CBT compared to PFPP.

Conclusions:

• Clinicians' intuitions about barriers to CBT for panic disorder were not supported by empirical data.
• Dissociation during panic attacks may be a marker of treatment response, not a barrier.
• Research should critically examine clinical intuitions, and dialogue between researchers and clinicians is encouraged.
