What this Trial Is About

Background: Social Anxiety Disorder (SAD) is a common mental problem, where people experience severe and disabling anxiety about social situations and interactions. It is highly prevalent world-wide and in Hong Kong, causing significant suffering/distress. While evidence-based interventions exist, e.g., cognitive behavioural therapy (CBT), there will be not enough trained therapists to meet the treatment demand so that the majority of the SAD patients receive no treatment. Internet-based therapies may offer a solution, given that they deliver treatment more cost-efficiently by requiring lesser therapist time so that more patients can be treated with the same therapist resources. One UK internet-based CBT protocol for SAD, iCBT(C\&W), shows high efficacy and efficiency in initial UK and Hong Kong trials with Englishspeaking patients. Objectives: 1. To develop and confirm the efficacy of a Chinese-language version of iCBT(C\&W), administered by clinical psychologists in standard therapist-guided format. 2. To develop an even more cost-efficient new self-help format with some minimal 'coaching' performed by trained psychology bachelor-level graduates - its efficacy expected as 'noninferior' to that of the therapist-guided format. Overall design: Three-arm parallel group randomised controlled noninferiority trial: Standard therapist-guided iCT-SAD vs. Guided self-help iCT-SAD vs. Waitlist Method: The iCBT(C\&W) protocol will be translated into Chinese. Approximately 110 Chinese adults with SAD will be recruited in Hong Kong and randomised into one of two treatment conditions, therapist-guided versus self-help. The treatment lasts 14 weeks. The primary outcome measure will be Liebowitz Social Anxiety Scale (self-report version).
