Self Reports

Although sex difference in the mean level of depressive symptoms has been well established, the sex difference in genetic and environmental influences on adolescent depressive symptoms is unclear. The current study conducted a meta-analysis of twin studies on sex differences in self- and parent-reported adolescent depressive symptoms. For self-reports, genetic factors influenced adolescent depressive symptoms equally for boys and girls, accounting for 46% of variation, but shared environmental factors had stronger impacts on adolescent girls’ versus boys’ depressive symptoms (13% versus 1% of the variance). For parent-reports, genetic, shared, and nonshared environmental factors influenced adolescent depressive symptoms equally, with separate estimates of 34%, 35%, and 31%. The implications of sex difference in genetic and environmental etiologies of depressive symptoms are discussed.

Post Intervention

Objective: Depression is a leading cause of disability among adolescents, yet existing treatments are variably effective, suggesting needs to identify novel intervention targets. Body dissatisfaction (BD) may be a promising, but understudied, target: BD is common among adolescents; prospectively associated with future depression; and modifiable through intervention. BD interventions are typically evaluated in terms of impacts on eating disorders, but many trials also measure depression-related secondary outcomes. However, BD intervention effects on depression have not been systematically examined. We therefore conducted a meta-analysis to estimate secondary effects of BD interventions on depression symptoms and related outcomes in adolescents (ages 12-19). Method: Our systematic review included RCTs published between January 2006-December 2020. Across-group effect sizes were analyzed using robust variance estimation. Pre-registered methods, data, and analytic code are available at https://osf.io/734n8/. Results: The meta-analysis included thirteen RCTs, 50 effect sizes, and 6,962 participants. BD interventions led to significant post-intervention reductions in depression-related outcomes versus control conditions (g = -.19 at post-intervention, 95% CI -.07, -.31, p = .005). No evidence emerged for moderators of this meta-analytic effect. Discussion: Overall, BD-focused interventions significantly reduced adolescent depression, with mean post-intervention effect sizes comparable to those observed for interventions targeting depression explicitly. Results are bolstered by pre-registered methods and robustness checks. Limitations include a lack of data on participants’ sexual and gender identities and a significant risk of bias in the underlying literature. Future research on BD interventions should measure depression symptom severity as a secondary outcome.
