Neuroticism and Adolescent Problematic Mobile Social Media Use: A Moderated Mediation Model.

Although previous studies have confirmed the influence of neuroticism on problematic mobile social media use, mechanisms underlying this relation have not been well-understood. The present study investigated the mediating effect of self-control, as well as the moderating role of family socioeconomic status (FSES). A total of 1146 adolescents' data ( M age = 16.11, SD age = 0.97, 498 boys) were collected. Participants completed questionnaires about neuroticism, self-control, problematic mobile social media use, and FSES. The moderated mediation analysis showed that self-control mediated the positive association between neuroticism and problematic mobile social media use. In addition, FSES moderated the negative relation between self-control and problematic mobile social media use. Specifically, compared with adolescents in low FSES, the association between self-control and problematic mobile social media use was stronger for adolescents in high FSES. This study advanced our understanding of the development of problematic mobile social media use by revealing the potential mechanism between adolescent neuroticism and problematic mobile social media use.
