Abstract [en]

The aim of this study was to evaluate if a population suffering from generalized anxiety disorder could benefit from an Internet based self-help treatment guided via email contact with a therapist. The treatment was based on established cognitive behavioral principles. It was hypothesized that significant improvements would be found as measured by eight self report questionnaires, absence of a clinical diagnoses and global clinical improvement. A total of 89 participants were included and 44 were randomized to a treatment condition and 45 were assigned to a waitlist control. The controls received similar treatment after the first post treatment assessment, conducted eight weeks after the beginning or treatment of the first group. The results showed statistically significant improvements for the treatment group. No changes were observed in the waiting-list control group, with the exception of a minor decrease in depression scores. Large effect sizes were found both within the treatment group and between the two groups in favor of the treatment. In conclusion, Internet treatment can be an efficacious format for treating generalized anxiety disorder.
