Abstract

Background We have previously reported benefits for reduced bullying, smoking, alcohol and other drug use and mental health from a trial of ‘Learning Together’, an intervention that aimed to modify school environments and implement restorative practice and a social and emotional skill curriculum.

Objectives To conduct post hoc theory-driven analyses of broader impacts.

Design Cluster randomised trial.

Settings 40 state secondary schools in southern England.

Participants Students aged 11/12 years at baseline.

Outcomes Student self-reported measures at 24 and 36 months of: cyberbullying victimisation and perpetration; observations of other students perpetrating aggressive behaviours at school; own perpetration of aggressive behaviours in and outside school; perceived lack of safety at school; participation in school disciplinary procedures; truancy and e-cigarette use.

Results We found evidence of multiple impacts on other health (reduced e-cigarette use, cyberbullying perpetration, perpetration of aggressive behaviours) and educational (reduced participation in school disciplinary procedures and truancy) outcomes.

Conclusion These analyses suggested that the intervention was effective in bringing about a broader range of beneficial outcomes, adding to the evidence that the intervention is a promising approach to promote adolescent health via an intervention that is attractive to schools.

Trial registration number ISRCTN10751359.
