Abstract
OBJECTIVE: Exposure to self-harm content may be an important experience on social media that confers risk for self-injurious thoughts and behaviors (SITBs). The current study used an intensive monitoring design to examine the relation between weekly exposure to self-harm content on social media and adolescent SITBs, including suicidal ideation and nonsuicidal self-injurious (NSSI) urges and behaviors. METHOD: Adolescents (N = 61; ages 14-17 years) recruited in the United States (49% girls, 62% LGBTQ+, 10% Asian, 20% Black, 16% Latine, 13% Multiracial, 41% White) completed 8 weeks of daily and weekly surveys. Daily surveys included questions about adolescents' suicidal ideation and NSSI urges and behaviors. Weekly surveys included exposure to self-harm content on social media and perceived daily social media hours. Logistic multilevel modeling was conducted to evaluate whether exposure to self-harm content on social media was associated with weekly SITBs, controlling for social media duration and depression symptoms. RESULTS: Overall, 50% (n = 31) of adolescents reported seeing self-harm-related content on social media over the study period. There were significant associations between weeks of self-harm social media exposure and weekly NSSI urges and behaviors. There was no association between weekly social media self-harm exposure and suicidal ideation that week. Perceived social media use duration was not associated with SITBs. CONCLUSION: Findings indicate that exposure to self-harm content on social media may be a proximal risk factor for NSSI urges and behaviors among adolescents. Findings shed light on one modifiable way in which social media may heighten risk for SITBs among adolescents, lending empirical support to current guidelines about limiting self-harm content on social media.
