The Role of Peer Support in the Growth Trajectory of Pathological Internet Use Among Youth: A Protective Factor.

Despite the escalating public concern about pathological use of the Internet among youth, little research has investigated the longitudinal trajectory of the problem and the role of peer support in it. This study aimed to determine the growth trajectory of pathological Internet use (PIU), identify latent subgroups presenting heterogeneous growth trajectories of PIU, and examine the initial status of and the rate of change in peer support as predictors of the growth trajectory of PIU among children and adolescents. Using four-wave longitudinal data from 3,079 Singaporean youth at ages 7-19, we performed Latent Growth Curve Modeling, Latent Class Growth Analysis and Latent Growth Mixture Modeling. Results revealed a downward trajectory of PIU among youth. We identified six latent subgroups, three of which were in pathological status for at least a year. The more rapid improvement in peer support, but not the initial level of peer support, predicted the faster reduction of PIU symptoms during the 3-year period. Findings suggest that although the symptoms of PIU among children and adolescents would decline over time, improving peer support could further alleviate youth PIU. We recommended that intervention programs include a peer support component to mitigate PIU among youth.
