This study is a two-arm, parallel-group, single-blind, early-stage Randomized Clinical Trial (RCT) with embedded qualitative components. Participants will be randomized in a 1:1 ratio to either intervention or control, with a total of 162 participants (81+81) in the trial. The primary outcomes are measures of gaming and gambling behavior pre- and post-intervention, and the secondary outcomes include child ratings of parent-child communication, including parental knowledge, control and solicitousness about child gaming, as well as child disclosure and secrecy related to gaming.~Preliminary analyses will be conducted with regression analyses, paired sample t-tests and ANOVAs and performed in Mplus. In addition to the RCT, the study will be supplemented with a qualitative component with semi-structured individual interviews to capture participants' and clinicians' experiences of the treatment, as well as attitudes about parent-child relationships and parenting needs in carers whose children completed the RP treatment. The qualitative data will be analyzed with thematic analysis.
The aim of the study is twofold: 1) to evaluate an Relaps Prevention(RP) treatment for Problematic Gaming (PG) and Internet Gaming Disorder (IGD) patients recruited from child and youth psychiatry (CAP) clinics and 2) to test whether the quality of parent-child relationships plays role in the effect of RP treatment and vice versa - whether the RP treatment has a spillover effect on the quality of parent-child relationships.
