Guided Self-Help via Internet for Panic Disorder in Adults: A Pilot Study

The present study examines the effectiveness of a guided self-help program via Internet on panic disorder (PD). Totally 27 participants with a confirmed PD diagnosis, either with or without agoraphobia, received treatment. The treatment consisted of a weekly 10-module program based on Cognitive Behavioural Therapy principles and weekly telephone contact with a psychologist. Participants were assessed pre-treatment, post-treatment, and 6 months after the completion of the treatment. The results showed significant improvements on PD-symptoms and other symptoms and problems (depression, sleep, and interpersonal problems) during the treatment period. These effects were maintained at a 6 months follow-up. Half of the treatment completers did not fulfil the criteria for a PD diagnosis at the follow-up. The participants were very satisfied with the treatment they received. Most of the effect sizes were high for treatment completers, but were reduced to medium when including those who did not complete the treatment. The present study did not find strong predictors for the treatment effects. The results from this study support continued use of guided self-help via Internet for the treatment of PD
