Purpose: To evaluate a meaning- and emotion-regulation-based intervention for preventing Problematic Interactive Media Use (PIMU) among Chinese rural adolescents. Method: In total, 106 high school freshmen (Mage = 15.15, SD = 0.47) were randomized to intervention or waitlist control. Four weekly 90-min sessions targeting meaning in life and emotion regulation were delivered by trained counselors, with assessments at baseline (T1), postintervention (T2), and 3-month follow-up (T3). Results: Repeated-measures analysis of variance revealed significant time × group interaction effects for meaning confusion, emotion dysregulation, and all three PIMU domains. The intervention group demonstrated significant reductions in problematic smartphone use at T2 and T3, and outperformed controls across all PIMU domains at T2. The control group showed significant increases in internet gaming disorder at follow-up. Discussion: A brief meaning- and emotion-based intervention is feasible and effective in preventing and reducing PIMU among Chinese rural adolescents. This study was prospectively registered at ClinicalTrials.gov (NCT05479344).
