Adolescents and Social Media: Longitudinal Links Between Types of Use, Problematic Use and Internalizing Symptoms

Studies examining the associations between adolescent social media use and depression/anxiety symptoms show inconsistent results and do not elucidate the direction of associations. Differences in how studies operationalize social media use and consider potential moderating effects of sex and extraversion could contribute to inconsistencies. A distinction has been made between three types of social media use: passive, active and problematic. This study examined longitudinal associations between these types of adolescents' social media use and depression/anxiety symptoms and moderation effects of sex or extraversion. At ages 13 (T1) and 14 (T2), 257 adolescents completed an online questionnaire regarding their depression and anxiety symptoms and problematic social media use as well as three social media use diaries. Cross-lagged panel modeling (CLPM) revealed a positive association between problematic use and later anxiety symptoms (beta = .16, p = .010). Extraversion moderated the association between active use and anxiety (beta = -.14, p = .032). Specifically, active use predicted higher subsequent anxiety symptoms only in adolescents with low to moderate levels of extraversion. No sex moderation was found. While social media use (active or problematic) predicted later anxiety symptoms (but not depression), the reverse was not the case. However, highly extraverted individuals seem to be less vulnerable to potential negative effects of social media use.

Automated summary

Studies on adolescent social media use and depression/anxiety symptoms have inconsistent results and do not clarify the direction of the associations. Differences in how social media use is defined and the consideration of moderating effects of sex and extraversion may contribute to these inconsistencies. This study examines the longitudinal associations between different types of social media use and depression/anxiety symptoms in adolescents, and explores the moderating effects of sex and extraversion.
