PROBTEC Program to Manage Problematic Technology Use in Adolescents

Excessive engagement with digital devices among adolescents has become a significant public health concern, contributing to reduced physical activity and associated health risks. This study assessed the impact of the PROBTEC Management Program-an intervention structured around the Health Promotion Model-on technology-related behaviors and activity levels in adolescents. A randomized controlled trial was implemented in 10 public middle schools in Türkiye with a total sample of 200 students aged 14-15 years. Schools were allocated to either the intervention or control condition using cluster randomization. The intervention spanned six weeks and combined health education sessions, guided physical activity practices, and parent-focused components. Measures were obtained at four time points (baseline, 1 week, 3 months, 6 months) using validated questionnaires, pedometer-based step counts, and the International Physical Activity Questionnaire. Data were analyzed using repeated measures statistical techniques and standardized effect size calculations. Participants receiving the PROBTEC intervention demonstrated notable improvements over time. Compared with controls, the intervention group exhibited reduced indicators of problematic technology engagement and perceived exercise barriers, alongside increases in perceived exercise benefits, physical activity self-efficacy, and total MET scores. Findings indicate that the PROBTEC Management Program supports positive behavioral changes by reducing unhealthy technology use and encouraging more active lifestyles among adolescents. The sustained effects observed across the 6-month follow-up period suggest that this school-based, theory-driven model may be a practical and scalable strategy for adolescent health promotion
