virtual reality based cognitive behavioral therapy for social anxiety among youths in hong kong

Conditions: Social Anxiety Disorder (SAD); Social Phobia

Summary: this randomized controlled trial evaluates the effectiveness of a vr-based cbt intervention for social anxiety-driven depression among hong kong youth (ages 15-24). given the limitations of traditional cbt in addressing deep-seated fears, this study explores a more engaging and scalable alternative. ninety participants with depressive symptoms and social difficulties will undergo six 60-minute vr sessions based on clark and wells' cognitive model of social phobia, with assessments at baseline, post-treatment, and three-month follow-up using the social phobia inventory and phq-9. the study investigates whether vr intervention reduces social anxiety-driven depression and assesses its cost-effectiveness. expected outcomes include symptom reduction, sustained benefits at follow-up, and evidence for vr as an innovative, scalable mental health intervention, informing clinical practice, research, and policy in hong kong and beyond.

background: youth depression in hong kong is a growing concern, with a significant number of secondary school and college students exhibiting depressive symptoms. social anxiety-driven depression, particularly prevalent in this demographic, poses a complex clinical challenge. current interventions such as cognitive behavioral therapy (cbt), while promising, have limitations in addressing deep-seated fears that hinder engagement in crucial behavioral experiments, and may not fully cater to youth-specific needs. method: this study employs a randomized controlled trial design to evaluate the effectiveness of a virtual reality (vr) based cbt intervention in treating social anxiety-driven depression among hong kong youths. 90 participants aged 15-24 years, displaying clinical symptoms of depression with self-reported difficulties in social events, will be enrolled. the intervention protocol, grounded in clark and wells' cognitive model of social phobia, includes six 60-minute vr sessions simulating various social scenarios. measurements will be taken at a baseline, post-treatment, and three-month follow-up using tools such as the social phobia inventory and patient health questionnaire-9. research questions: the study primarily investigates whether vr intervention leads to a significant reduction in social anxiety-driven depression post-treatment and follow-ups, as well as the cost analysis of the vr intervention in managing such depression. expected outcomes and implications: the study anticipates that vr intervention will effectively reduce depression and social anxiety symptoms among participants, with sustained benefits at the three-month follow-up. it is also expected to offer a cost-effective, scalable, and engaging alternative to traditional therapies, addressing a critical gap in youth depression. the findings could have significant implications for academia, practice, providing evidence for the adoption of innovative technology in mental health interventions, and informing future research and policy decisions regarding mental health care for youths in hong kong and beyond.
