Adapted and Translated, Adolescent Depression, Internet Intervention

Objectives : The key objective of this study is to develop new interventions that addresses the diverse needs and circumstances of Hong Kong adolescents with depressive symptoms in community settings. Collaboration between medical professionals and social workers may prevent the occurrence of depression and misguided attempts to self-treat with alcohol and / or drugs in our adolescents. Methods : To address this intervention gap in the United States, Dr. Van Voorhees, a research collaborator of Dr. Chim and Dr. Ip, developed and conducted a phase 2 clinical trial of a primary care internet-based depression prevention intervention (CATCH-IT, Competent Adulthood Transition with Cognitive Behavioral Humanistic and Interpersonal training). It has been observed clinically that the strategy could reduce depressed mood, increased social support and reduced depressive episodes at 12 month follow-up. The investigators now propose to study if an adaptation of the CATCH-IT website for Hong Kong Chinese adolescents may lead to significant reductions in depressed mood. In this pilot trial, the investigators propose to test the efficacy of the Adapted and Translated version of CATCH-IT (AT-CATCH) against the placebo approach in preventing the onset of depressive episodes in a group of adolescents (aged 13-17) who have depressive symptoms, but have not developed depression yet.The case group will have access to the AT-CATCH website while the control group will only be allow to use the anti-smoking website. The investigators hypothesize that compared to youth in the control group, youth assigned to the AT-CATCH group will have a lower hazard ratio of major depressive episodes and decreased alcohol / drug use frequency over 2 years. Moreover, compared to youth in the control group, youth in the AT-CATCH program will demonstrate a steeper slope of improved symptoms through growth curve analysis and fewer depressed days over the study period.
