Efficacy of a cognitive-behavioural therapy administered by videoconference for generalized anxiety disorder

Abstract Introduction Delivering psychotherapy by videoconference could considerably extend the accessibility of empirically validated treatments. Objective The aim of this study was to evaluate the efficacy of a cognitive-behavioural therapy (CBT) for generalized anxiety disorder (GAD), administered via videoconference. Method Five participants with a primary diagnosis of GAD took part in an experimental multiple baseline case study protocol. The efficacy of the treatment was evaluated using a semi-structured interview, self-report questionnaires, and daily self-monitoring diaries. Results The results demonstrate that overall, participants’ conditions were improved following treatment and they no longer met the diagnostic criteria for GAD in the short-term. Participants’ conditions improved clinically and statistically at each follow-up point, achieving a greater global level of functioning at post-test, as well as at 3-month and 12-month follow-up. Conclusion Clinical implications of this new treatment modality and directions for future research are discussed.
