Is this trial a fit for you?

Likely a good fit

Ideal candidates are adolescents aged 10-16 in Hong Kong with probable IGD (IGDS9-SF score above the cutoff), who can nominate a close CSO and have consent to participate.

Probably not a fit

Patients without a willing CSO or those not meeting the high-risk IGD criteria may not experience substantial benefit.

What this trial studies

Researchers will randomly assign adolescents in Hong Kong who show high risk for IGD to receive collective motivational interviewing plus IGD education materials for both the teen and their caregiver, or education materials alone. The approach combines motivational interviewing delivered to the adolescent with coordinated materials for the CSO to support behavior change. Outcomes are measured at baseline, after the intervention, and at 3- and 6-month follow-ups to see changes in IGD severity, motivation to change, cravings, and social support. The trial aims to determine if adding the CMI modality improves results beyond education materials alone.

Why it matters

Potential benefit: If successful, teens may experience reduced IGD symptoms and stronger social support from caregivers, potentially improving functioning and well-being.

How similar studies have gone: Previous research suggests motivational interviewing approaches can support behavior change, but effects in a collective, adolescent-family context are less well established and require confirmation.
