Effect of Home-Based Positive Behavior Support on Children’s Overdependence on Smartphone: Problem Behavior Caused by Smartphone and Self-Management Skills

The purpose of this study was to examine the impact of home-based positive behavior support on problem behavior and self-management skills in children who rely on smartphones. The subjects of the study conducted individualized positive behavioral support for two third-grade boys and one girl using probe design across subjects. It provided positive home-based action support after establishing functional behavior assessment, background/precedence strategy, alternative behavior teaching strategy, and follow-up outcome strategy within the evening and time of families, a natural environment where smartphone overdependent behavior is frequently occurring. As a result, individualized positive behavior support at home increased self-management skills acquired during the intervention and reduced problem behavior in target children. The limitation of the study was discussed and future direction has been suggested.
