This cluster randomized controlled trial was conducted in two public middle schools located in the city center of Türkiye during the 2024-2025 academic year. Schools with similar socio-demographic characteristics were identified, and two schools were selected through a lottery method. One school was assigned to the intervention group and the other to the control group to minimize contamination between participants.
The study targeted students aged 10-14 years identified as being at high risk for digital game addiction based on screening assessments. The intervention consisted of four weekly classroom sessions grounded in Self-Regulation Theory. The program included structured activities focused on self-monitoring of digital gaming behaviors, goal setting, impulse control strategies, time management skills, and sleep hygiene awareness.
The control group did not receive the intervention during the study period and continued their routine school curriculum.
Primary outcomes included levels of digital game addiction and sleep deprivation, measured using validated and age-appropriate standardized scales. Assessments were conducted at baseline (pre-intervention) and after completion of the intervention.
The primary objective of the study is to evaluate the effectiveness of a theory-based school intervention in reducing digital game addiction and sleep deprivation among adolescents.
