Internet-delivered acceptance-based behavior therapy for generalized anxiety disorder: A pilot study

Abstract

ObjectiveInternet-delivered cognitive behavior therapy (ICBT) has been developed and tested for treating persons with generalized anxiety disorder (GAD). A new form of CBT focuses on acceptance (of internal experiences or difficult psychological content), mindfulness and valued actions. To date this form of CBT has not been delivered via the internet for persons with GAD. The aim of this study was to describe the functionality of a new internet-delivered acceptance-based behavior therapy for GAD, and to test the effect of the intervention in an open pilot trial. MethodsFollowing exclusion of two patients we included 14 patients diagnosed with GAD from two primary care clinics. At 2–3months follow-up after treatment 10 patients completed the outcome measures. The treatment lasted for an average of 15weeks and consisted of acceptance-based techniques, behavior therapy components and homework assignments. ResultsA majority of participants completed all modules during the treatment. Findings on the Penn State Worry Questionnaire showed a within-group improvement of Cohen's d=2.14 at posttreatment. At the follow-up results were maintained. Client satisfaction ratings were high. ConclusionsWe conclude that internet-delivered acceptance-based behavior therapy potentially can be a promising new treatment for GAD. A controlled trial of the program has already been completed.
