Boers E, et al. - Researchers examined how several types of screen time are related with depression in adolescence. From a randomized clinical trial assessing the 4-year effectiveness of a personality-targeted drug and alcohol prevention intervention, data were obtained for this secondary analysis. Using an annual survey in a sample of adolescents who entered the seventh grade in 31 schools in the Greater Montreal area, screen time and depression were assessed throughout 4 years. Significant between-person correlations showed that for every increased hour spent using social media, adolescents showed a 0.64-unit increase in depressive symptoms, with comparable results for computer use. Both screen time means should be accounted when developing preventive measures for depression and when advising parents.
