Background: Depression prevention among adolescents is crucial for reducing the global disease burden. Internet-based depression prevention approaches are found to be effective but they were mostly evaluated in a Western context. Grasping the Opportunity is a Chinese Internet intervention, which was translated and modified from CATCH-IT developed in the West. We aimed to evaluate the effectiveness of Grasp the Opportunity in reducing depressive symptoms in Chinese adolescents. Methods: In this randomized controlled trial, Chinese adolescents aged 13 to 17 years with mild-to-moderate depressive symptoms were recruited from three secondary schools in Hong Kong. The participants (n = 257) were randomly assigned to receive either intervention or attention control. The primary outcome was the improvement in depressive symptoms according to the revised Center for Epidemiologic Studies Depression Scale (CESD-R) at the 12-month follow-up. Analyses were performed using intention to treat (ITT). Results: The participants were randomly assigned to receive the intervention (n = 130) or attention control (n = 127). Follow-up data were obtained from 250 (97%) participants. Only 26 (10%) participants completed the intervention. Compared to the attention control, Grasp the Opportunity led to reductions in depressive symptoms at the 12-month follow-up with a medium effect size using ITT analysis (mean difference 2.6, 95% CI 0.59–5.55, effect size d = 0.36). Conclusions: Grasp the Opportunity is effective in reducing depressive symptoms in Chinese adolescents over a long follow-up period. Poor completion rate is the major challenge in the study.
