Abstract
This study profiled the association between social–emotional competencies, psychological well-being (PWB), and secondary/middle school transition. Analysis drew from 233 sixth-class/sixth-grade students aged 11–13 years who completed measures of emotion regulation, perceived social support, self-esteem, and PWB at baseline and 1-month follow-up in primary school, and at 6-month follow-up post-secondary school transition. COVID-19 school closures, school socioeconomic status and gender were examined as moderators. Repeated-measures multi-level models revealed a significant decline in boys’ emotional suppression use, an increase in boys’ self-esteem, and a decline in girls’ PWB across the transition. Further, perceived social support, self-esteem, and gender were significant predictors of post-transition PWB while controlling for baseline PWB. This highlights the importance of enhancing social support and self-esteem across secondary school transition and considering gender differences in school transition effects. Policymakers should consider interventions that bolster these factors during this critical developmental phase.
