Psychometric Properties of the Smartphone Addiction Proneness Scale for Adolescents in the Indonesian Version

This study aims to test the validity and reliability of the Indonesian version of the Smartphone Addiction Proneness Scale (SAPS) in the adolescent population. This study involved 252 adolescents aged 12–18 years from various high schools in Indonesia. Construct validity test was conducted using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Sampling adequacy was confirmed with a Kaiser–Meyer–Olkin (KMO) value of 0.745. While reliability was measured through Cronbach's alpha coefficient, average variance extracted (AVE) value, and composite reliability (CR). EFA identified a two-factor structure. CFA demonstrated acceptable model fit. The Cronbach's alpha value of 0.799 indicates good internal consistency. The Indonesian version of SAPS demonstrates satisfactory validity and reliability for assessing smartphone addiction proneness among adolescents. These findings suggest that the Indonesian version of SAPS can be used as an early screening tool in educational and mental health settings.
