Background: Cognitive therapy for SAD (CT‐SAD) is a first‐line recommended treatment for adult social anxiety disorder (SAD) and shows considerable promise for youth. However, the high prevalence of adolescent SAD and limited number of therapists presents an implementation challenge. Delivery of CT‐SAD via the Internet may offer part of the solution. Method: Forty‐three youth (14–18 years) with SAD recruited through schools were randomly allocated to therapist‐assisted Internet‐delivered CT‐SAD (called OSCA) or waitlist for 14 weeks (ISRCTN15079139). Results: OSCA outperformed waitlist on all measures and was associated with large effects that were maintained at 6‐month follow‐up. In the OSCA arm, 77% of adolescents lost their SAD diagnosis at post (vs. 14% in the waitlist arm), increasing to 91% at 6‐months. Beneficial effects of OSCA were mediated through changes in cognitions and safety behaviours as predicted by cognitive models of SAD. OSCA was associated with high credibility and therapeutic alliance. Conclusions: This preliminary trial suggests OSCA holds promise as an effective, accessible treatment for adolescent SAD. Future definitive trials could compare OSCA to active comparators to examine specificity of effects. [ABSTRACT FROM AUTHOR]
