Dataset: When Social Media Hurts: A 9-Month Prospective Study on Self-Blame as a Mediator Between Problematic Social Media Use and Suicidal Ideation in Adolescents.

Despite reviews investigating the associations between PSMU, emotion regulation, and suicidality, there is a lack of understanding of the potential role that specific emotion regulation might play. This study aimed to bridge this gap by examining the mediating role of four specific maladaptive cognitive emotion regulation strategies (CERS) (i.e., rumination, self-blame, other-blame, catastrophizing) in the prospective link between PSMU and suicidal ideation in a sample of 517 adolescents (M = 13.41, SD = 1.06).

Results showed that PSMU was significantly associated with suicidal ideation nine months after. Maladaptive CERS were negatively associated with both PSMU and suicidal ideation, with the exception of other-blame, that was not significantly related to PSMU. Findings of mediation analyses indicated that solely self-blame mediates the negative and prospective link between PSMU and suicidal ideation.
