Feasibility and effectiveness of an Internet-based program for the prevention and early intervention of depression inInternet adolescents

Background: the high prevalence of depression in adolescence and its serious consequences, associated with its lack of detection and treatment, stimulate interest in research regarding its early prevention and intervention. Interventions based on information and communication technologies (ICT), given their flexibility and capacity for dissemination, represent innovative opportunities; however, in Latin America there is little evidence on their impact and efficacy. Objective and Methods: a quasi-experimental quantitative pilot study was carried out to evaluate the feasibility, through the variables of use and acceptability, and the estimated effect of the Internet-based program "Cuida tu animo", in 215 adolescents (103 active group, 112 control group) from two educational institutions. The adolescents' interactions with the program, its use-acceptability, and the level of depressive symptomatology and other related aspects were evaluated. Results: the adolescents report high acceptance and very moderate use of the Program. They point out that the program allowed them to learn about depression and early detection of risk; also, they recommend increasing the interactivity of the web platform, designing more diverse and entertaining content, and increasing the presence of the intervention. Conclusions: Internet-based programs such as Cuida tu animo can be a favorable complement for the prevention and early intervention of depression in adolescents. Considering the difficulty in relating the estimation of the Program's effect with its use, it is recommended that future studies include a design that permits associating the use indicators with the outcome indicators (dose-effect).
