Abstract
BACKGROUND AND AIMS: Mobile phone bans in secondary schools are claimed to reduce student distraction and promote learning and face-to-face socializing. Currently, the evidence on phone bans is limited. The aim of this preregistered study was to evaluate the South Australian mobile phone ban's effects on students' problematic phone use, academic engagement, school belonging, and bullying. The study also sought to identify student variables that predict phone ban compliance. METHODS: As the ban was phased in over 2023, a 2 (phone ban: yes/no) × 2 (time: baseline, 1-month follow-up) repeated-measures design was employed. Students (n = 1,282 at baseline; n = 1,256 at follow-up) in Grades 7 to 12 were recruited from five public secondary schools. Surveys included measures drawn from the Longitudinal Study of Australian Children (LSAC) and the Programme for International Student Assessment (PISA). RESULTS: Problematic phone use was reported by 2.6% of the sample. Being older and a more frequent user of social media predicted lower phone ban compliance. Linear mixed models indicated that ban and no ban school groups did not differ significantly in terms of problematic phone use, academic engagement, and school belonging. There was slightly higher bullying in the ban group but bullying decreased significantly in both groups. DISCUSSION: Imposing access restrictions may not affect the underlying psychological mechanisms that drive problematic phone use. Although these results indicate limited to no short-term benefits of the ban, further evaluation with more sensitive methodologies is recommended. CONCLUSIONS: Student-technology interactions in learning institutions should be continually monitored to determine the optimal balance to support student etiquette, learning, and wellbeing.
