Sleep disturbances partially mediate the association between problematic internet use and somatic symptomatology in adolescence

Abstract

The Internet is widely used among adolescents for different purposes, including social connections, entertainment and schoolwork. Nevertheless, research has demonstrated the negative impact of problematic internet use (PIU) on psychophysical well-being in adolescence. This study aims to investigate internet use and its association with somatic symptoms, exploring the specific role of sleep disturbances that affect overall sleep quality. A mediation model was used to demonstrate the link between PIU, somatic symptoms and sleep disturbances in a sample of 412 adolescents (52% of males) aged 10–17 (M = 14.12, SD = 1.46). We also investigated whether somatic symptoms were differently experienced and reported by participants at risk of developing internet addiction (n = 58) from those not-at risk (n = 354). Sleep disturbances partially mediated the relationship between PIU and somatic symptoms. Furthermore, PIU seems to lead to poorer sleep quality which may in turn result in physical problems with an increase in somatic symptoms. Findings of this study showed that adolescents at risk of developing internet addiction suffered from a specific somatic symptomatology respect to those not-at risk. Finally, PIU has a positive direct effect on somatic symptoms. These results highlight the role of sleep disturbances with implications for overall sleep quality in the association between PIU and somatic symptoms. When designing intervention programs, the associations between PIU, sleep quality and somatic symptoms in adolescence and the negative repercussions of PIU on psychophysical health should be kept in mind. Results are discussed within the context of recent scientific research.
