Is this trial a fit for you?

Likely a good fit

Ideal candidates are Hong Kong residents aged 18+ who consider generalized social anxiety their main problem, are proficient in written traditional Chinese and spoken Cantonese, have home internet access, and do not have disqualifying psychiatric comorbidities or prior CBT for SAD.

Probably not a fit

Patients with current or past psychosis, bipolar disorder, borderline personality disorder, active suicidality, moderate/severe substance or alcohol use disorder, the performance-only SAD subtype, or prior CBT for SAD are unlikely to benefit from this program.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Researchers will adapt the UK iCBT(C&W) protocol into traditional Chinese and deliver it online to adults in Hong Kong who meet criteria for generalized social anxiety disorder. Participants who are Cantonese-speaking and have internet access will be randomized to versions with clinician guidance or coach support and complete the self-help modules remotely. Key exclusions include current psychosis, bipolar disorder, borderline personality disorder, active suicidality, moderate-to-severe substance or alcohol use disorder, or prior CBT for SAD. Outcomes will compare symptom change and feasibility between the two guidance formats.

Why it matters

Potential benefit: If successful, this could expand affordable, effective treatment options for social anxiety in Hong Kong by reaching more patients with less therapist time.

How similar studies have gone: Similar internet-based CBT programs, including the original UK iCBT(C&W), have shown high efficacy in prior UK and Hong Kong trials with English-speaking patients.
