#Trending: A Systematic Review of Social Media Use’s Influence on Adolescent Anxiety and Depression

With new technological advancements, adolescents can obtain devices that give them virtually unlimited access to social media (SM) which may impact adolescent mental health. This literature review aims to evaluate the influence of social media use on adolescent anxiety and depression. A literature search of PubMed from June 2010 through June 2020 was completed for the following MeSH terms: social media, adolescent, anxiety, depression, and mental health. English language articles that discussed adolescents aged 13 to 18 years, anxiety and/or depression and SM were included. Extracted data included the SM platform, impact on anxiety and depression, interventions, temporal and dose-response relationships, and observed versus self-reported usage. The majority of articles positively associated depression (82.6%) and anxiety (78.3%) with SM use. depression corresponded with cyber-bullying (42.1%), negative social perspective (21.0%), diminished self-esteem (15.8%), and sleep disturbance (10.5%). Anxiety corresponded with a negative social perspective (44.4%), diminished self-esteem (33.3%), sleep disturbance (16.7%), and cyber-bullying (16.7%). Many studies suggested the use of interventions to reduce depression (72.7%) and anxiety (72.7%), such as screen time restrictions (n=6) and social support (n=4), but lacked evaluation of their implementation. Current literature suggests a positive association between adolescent SM use with anxiety and depression. Our study highlights the need for further investigation of temporal and dose-response associations between SM use and adolescent mental health, and the potential benefits of SM-driven interventions.
