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

Date Published: 2026-09-25

Abstract:
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. Data were obtained in November 2025 from six schools across three Chinese provinces. The analytic sample included 1,622 adolescents, comprising 772 males and 850 females. Participants completed measures of emotional maltreatment, narcissism, problematic short-video use, and physical activity. Emotional maltreatment was positively associated with problematic short-video use, and an indirect statistical association was observed through narcissism. Physical activity moderated the direct association between emotional maltreatment and problematic short-video use, which was weaker at higher levels of physical activity. Considering a personality characteristic and a health-related behavior within the same model provides a broader understanding of the circumstances under which emotional maltreatment is associated with problematic short-video use. These findings may inform family- and school-based support concerning adolescents’ emotional needs, healthy short-video use, and regular physical activity.
