anxiety disorder, SAD
WELLS
Based on a recent meta-analysis, there is evidence that internet- or app-based interventions have moderate effect sizes in the treatment of SAD [We hypothesize that the addition of therapist-guided sessions will result in larger effect sizes than using the app alone. In agreement with Stott et al. [To summarize, our results will demonstrate (a) the efficacy of a new app-based intervention using the Clark and Wells approach in another well-designed and preregistered independent trial and (b) whether additional face-to-face therapy is beneficial to patients in terms of increased symptom reduction of SAD compared to app use alone. The results will be critical for service delivery and treatment planning for social anxiety disorder.
