A systematic review and synthesis of theories of change of school-based interventions integrating health and academic education as a novel means of preventing violence and substance use among students

Abstract

BackgroundSchools can play an important role in promoting health. However, many education policies and institutions are increasingly emphasising academic attainment targets, which appear to be diminishing the time available for health education lessons. Interventions that integrate both health and academic learning may present an ideal solution, simultaneously addressing health education and academic development. The theories of change underlying these interventions are therefore of interest, but are poorly studied.MethodsA systematic review of evaluations of interventions that integrate academic and health education for reduced substance use and/or violence was carried out. As part of this, reports describing theory were assessed for quality and data extracted. Theoretical data were synthesised within and across individual interventions using reciprocal translation and meta-ethnographic line of argument synthesis to produce an overall theory of change for interventions that integrate health and academic education to prevent substance use and violence.ResultsForty-eight reports provided theoretical descriptions of 18 interventions. An overarching theory that emerged was that eroding ‘boundaries’ at multiple and mutually reinforcing levels—by integrating academic and health education, by transforming relationships between teachers and students, by generalising learning from classrooms to the wider school environment and by ensuring consistent messages from schools and families—is intended to lead to the development of a community of engaged students oriented towards pro-social behaviour and away from substance use, violence and other risk behaviours.ConclusionsEroding ‘boundaries’ between health and academic education, teachers and students, classrooms and the wider school and schools and families were seen to be the most critical to establishing new frameworks of family, classroom or school organisation that are conducive to promoting both academic and social-emotional outcomes. Whether such interventions are feasible to implement and effective in reducing risk behaviours will be examined in other reports arising from the review.Electronic supplementary materialThe online version of this article (10.1186/s13643-018-0862-y) contains supplementary material, which is available to authorized users.

Barriers and facilitators to the implementation of Health-Promoting School programmes targeting bullying and violence: a systematic review

“…The importance of stakeholder buy-in is well described for any kind of health promotion activity, including school-based approaches. [18][19][20][21]42,43] This review corroborates this from the perspective of school community stakeholders, and identifies key influences of stakeholder buy-in and programme characteristics that may further enable implementation. Findings with high or moderate confidence ratings are summarised below.…”

“…and R.P.) using a modified version of pre-existing criteria concerning whether the theory(ies) (1) described pathways from intervention to outcome, (2) included clear concepts/constructs, (3) described inter-relations between concepts, (4) explained programme mechanisms of action, and (5) explained how mechanisms might differ by place/person(Bonell et al, 2016; Meiksin et al, 2021; Tancred et al, 2018). High-quality reports were given greater narrative weight in syntheses.…”

“…The school environment is an effective and efficient place to reach large numbers of young people and the cost of implementation is low ( Tancred et al, 2018 ). In Australia, mandatory health curricula ensure students in Years 8–10 (ages 13–16) receive substance use education, however senior students in Years 11–12 (ages 16–18) are not guaranteed the same education – despite this being the average age of initiation and escalation of substance useGuerin NaW, 2017; Xu et al, 2020;15 ( Guerin NaW, 2017 , Xu et al, 2020 ).…”
