Psychological needs satisfaction and smartphone addiction among Chinese adolescents: The mediating roles of social anxiety and loneliness

Although previous studies have initially noted that psychological needs satisfaction (PNS) might be a significant risk factor for technology addiction (e.g. online gaming addiction and Internet addiction), specific mechanisms involved in the association between PNS and adolescent smartphone addiction are largely unknown. Based on self-determination theory, this cross-sectional study constructed a multiple mediation model to examine whether PNS will influence adolescent smartphone addiction through the mediating roles of social anxiety and loneliness.Eight hundred and ninety-nine Chinese adolescents answered the questionnaire including measures of PNS, social anxiety, loneliness, and smartphone addiction. SPSS 24.0 was used for common method bias test, reliability test, and correlation analysis, and Mplus 7.4 was used to examine the mediating roles of social anxiety and loneliness in the multiple mediation model.This study found that (1) PNS was negatively associated with adolescent smartphone addiction; (2) loneliness significantly mediated the association between PNS and smartphone addiction while the mediating role of social anxiety in this association was nonsignificant; and (3) social anxiety and loneliness also sequentially mediated this association.This study further enriched potential mechanisms linking PNS and smartphone addiction among adolescents, which may contribute to intervention and prevention programs for adolescent smartphone addiction from the perspective of improving both PNS and negative emotions including social anxiety and loneliness.
