Cognitive and Self-Determination Predictors of Adolescents’ Commitment to Prevent Smartphone Addiction

Aims: Smartphone addiction among adolescents has become a growing public health concern. This study applied the health promotion model and self-determination theory to identify cognitive and motivational factors associated with adolescents’ commitment to preventing smartphone addiction. Instrument & Methods: This cross-sectional study included ۳۰۷ senior high school students from five public schools in Malang City, Indonesia, selected using cluster random sampling. Data were collected using validated questionnaires adapted from the health promotion model framework, the Basic Psychological Needs Scale, and the Smartphone Application-Based Addiction Scale. Structural equation modeling using SmartPLS was employed to examine the relationships among perceived barriers, self-efficacy, competence, autonomy, relatedness, and commitment to preventing smartphone addiction. Findings: Competence was the strongest positive predictor of commitment to preventing smartphone addiction (β=۰.۴۸۸; p<۰.۰۰۱), followed by relatedness (β=۰.۲۱۳; p<۰.۰۰۱). Self-efficacy showed a significant negative association with commitment (β=−۰.۱۲۴; p=۰.۰۲). In contrast, autonomy (β=۰.۰۱۶; p>۰.۰۵) and perceived barriers (β=−۰.۰۴۷; p>۰.۰۵) were not significant predictors. The measurement model demonstrated satisfactory validity and reliability, while the structural model showed an acceptable fit (SRMR=۰.۰۶۹) and explained ۴۵.۲% of the variance in commitment (R²=۰.۴۵۲). Conclusion: Competence, relatedness, and self-efficacy predict adolescents’ commitment to preventing smartphone addiction, with competence emerging as the strongest predictor.
