ABSTRACT

This study aims to develop and validate a scale for measuring the rapidly growing problem of smart media use in young children (PSMU). An exploratory factor analysis was conducted with 14 items derived from interviews, pilot testing with mothers of toddlers aged 18 months to 5 years and content validation. The exploratory factor analysis involved 425 mothers, resulting in nine items selected for three factors. To validate this scale, we conducted a confirmatory factor analysis, correlation analysis, mean comparison, and nomological network analysis with another 345 mothers of toddlers. The results showed that the PSMU scale is a reliable and valid measure of parent-reported child craving for and dependence on smart media and parental permission levels. The development and validation of the PSMU scale are significant in providing a foundation for appropriate early intervention based on accurate assessments that consider the developmental aspects of infants and toddlers.
