Interoceptive exposure versus breathing retraining within cognitive-behavioural therapy for panic disorder with agoraphobia.

This study compared two components of a cognitive-behavioural treatment for panic disorder. Thirty-eight individuals with panic disorder and agoraphobia were randomly assigned to (a) cognitive restructuring, interoceptive exposure (i.e. repeated exposure to feared bodily sensations) and in vivo exposure to agoraphobic situations; or (b) cognitive restructuring, breathing retraining and in vivo exposure to agoraphobic situations. Assessments were conducted at pre-treatment, post-treatment and six months later. The treatments were equally effective on many measures. However, treatment that included interoceptive exposure was more effective at post-treatment in terms of panic frequency, overall severity and functioning, and more effective at six-month follow-up in terms of panic frequency, phobic fears and general anxiety and functioning. Follow-up results were limited due to attrition.
