The influence of meaning in life on children and adolescents' problematic smartphone use: A three-wave multiple mediation model

Abstract

Using a three-wave longitudinal design, the current study examined the relationship between early meaning in life and subsequent problematic smartphone use (PSU). As depression and self-control are a strong predictor of Internet-related addiction, we examined these two variables as possible mediators in this relationship based on existing literature. A total of 478 Chinese children and adolescents (243 boys and 235 girls, mean age = 11.26 years) completed questionnaires regarding meaning in life, depression, self-control and PSU. The results indicated that: (a) presence of meaning and search for meaning are positive correlation, and they are negatively associated with PSU among children and adolescents; (b) depression and self-control mediated the link between presence of meaning and children and adolescents' subsequent PSU respectively; and (c) depression and self-control sequentially mediated the relationship between early presence of meaning and children and adolescents' subsequent PSU; whereas not sequentially mediated the relationship between search for meaning and children and adolescents' subsequent PSU. These results suggested that three types of interventions could be effectively used to decrease the risk of PSU among children and adolescents, namely, enhancing presence of meaning, relieving depression, and improving self-control.
