Description

The present study examines the efficacy of CMI in reducing adolescent IGD symptoms and enhancing social support given by CSOs among adolescents with high risk of IGD (probable IGD cases screened positive by validated tools). It is hypothesized that the intervention group (with CMI plus IGD education materials for both the clients and his/her selected CSO) would show more improvements in reduction in the severity of IGD, motivation to change maladaptive gaming behaviour, craving on gaming, and social support obtained from CSOs than to the control group (only educational materials for both the client and the CSOs).

Interventions

Collective Motivational Interviewing plus Education Materials (Behavioral)
The participants in the intervention group will receive IGD educational materials as well as four counseling sessions of CMI intervention.
Control group (Education Materials) (Other)
The participants in the control group will receive IGD educational materials.
