Emotional maltreatment and problematic short-video use among adolescents: an indirect association through narcissism and moderation of the direct association by physical activity

Introduction

Emotional maltreatment has been associated with problematic short-video use during adolescence, but the nature of this association remains unclear. This cross-sectional study examined the association between emotional maltreatment and problematic short-video use, estimated the indirect statistical association through narcissism, and tested whether physical activity moderated the direct association between emotional maltreatment and problematic short-video use.
