Researchers from Maastricht University, The Netherlands, compared the effects of CBT (Cognitive Behavioral Therapy) with IPT (Interpersonal Psychotherapy – a form of therapy that focuses on relationships) for treating panic disorder with agoraphobia.
Ninety-one adult patients with a primary diagnosis of panic disorder with agoraphobia were randomized to either a CBT condition or IPT. The primary outcome measured was panic attack frequency, along with a behavioral test.
Secondary outcomes were panic and agoraphobia severity, panic-related thoughts, interpersonal functioning and general psychopathology. Measures were taken at 0, 3 and 4 months (baseline, end of treatment and follow-up).
Intention-to-treat (ITT) analyses on the primary outcomes indicated superior effects for CBT in treating panic disorder with agoraphobia.
Reductions in the secondary outcomes were equal for both treatments, except for agoraphobic complaints and behavior and the credibility ratings of negative interpretations of bodily sensations, all of which decreased more with CBT.
The investigators conclude that CBT is the preferred treatment for panic disorder with agoraphobia, as compared to IPT.
