Strategies For Identifying And Preventing Adolescent Depression: Summarizing 15 Years Of Research
With depression predicted to contribute to an increased disease burden in coming decades, prevention efforts have become increasingly important. Prevention needs to commence early in the lifecycle, possibly even with children as young as four years of age. To identify children and adolescents who are most at risk, our research looked to understand sub-groups of children with similarities in the development of depressive symptoms over time. We reviewed twenty English language longitudinal studies published between 2002 and 2015 originating in USA (8), Canada (5), Netherlands (2), Germany, Finland, Chile, Holland, and the UK/Wales/Scotland. We found five subgroups of children and adolescents through a unique statistical analysis known as trajectory modeling. While the majority (56%) of children followed a ‘No or low’ depressive symptom trajectory over time, 26% followed a ‘Moderate’ depressive symptom trajectory and 12% followed ‘High’, ‘Increasing’, or ‘Decreasing’ depressive symptom trajectories (total of 94% is due to rounding across studies).
