  • Factors affecting the implementation of a whole-school relationships and sexual health intervention

    Open AccessRuth Ponsford, Rebecca Meiksin et al.ARTICLESex Education2026

    Whole-school relationships and sexual health interventions represent promising approaches to promoting healthy sexual development. However, data from a randomised controlled trial of the Positive Choices whole-school intervention demonstrate these may be challenging to implement in English secondary schools. We draw on qualitative data to examine staff perspectives on the implementation of the intervention and the factors affecting delivery. Inte…

  • Reporting of equity in observational epidemiology

    Open AccessOmar Dewidar, Ali Al-Zubaidi et al.ARTICLEJournal of Global Health2024

    Background: Observational studies can inform how we understand and address persisting health inequities through the collection, reporting and analysis of health equity factors. However, the extent to which the analysis and reporting of equity-relevant aspects in observational research are generally unknown. Thus, we aimed to systematically evaluate how equity-relevant observational studies reported equity considerations in the study design and an…

  • Testing and refining middle-range theory in evaluations of public-health interventions

    Chris Bonell, Ruth Ponsford et al.ARTICLEJournal of Epidemiology and…2023

    Evaluations of public-health interventions might potentially be used to test and refine middle-range theory (ie, theory about the mechanisms, which generate outcomes that is analytically generalisable enough to span a range of contexts, interventions or outcomes, but specific enough to be salient in a given application). This approach has been suggested as one means of developing more informed assessments of how different interventions work and w…

  • A realist synthesis to develop an explanatory model of how policy instruments impact child and maternal health outcomes

    Open AccessMaxwell S Barnish, Si Ying Tan et al.ARTICLESocial Science & Medicine2023Referencias: 145

    This paper presents a realist synthesis to develop an explanatory model of how policy instruments impact child and maternal health outcomes from a large, systematically identified international body of evidence. Five final programme theories were supported, showing how policy instruments play an important yet context-dependent role in influencing child and maternal health outcomes

  • Whole-school interventions promoting student commitment to school to prevent substance use and violence

    Open AccessRuth Ponsford, Jane Falconer et al.ARTICLEHealth Education Journal2022

    Objectives: Whole-school interventions and programmes aim to change school environments to promote health. Previous reviews suggest these are often inappropriately informed by individualistic psychological theories. We undertook a systematic review of whole-school interventions to prevent substance use and violence. This paper reports on a synthesis of theories of change, assessing whether these aligned with, and suggested refinements to, the the…

  • Methodological reflections on using qualitative research to explore the causal mechanisms of complex health interventions

    Open AccessChris Bonell, Emily Warren et al.ARTICLEEvaluation2022Citada por: 10Referencias: 11

    We reflect on how qualitative research can be used to develop or refine theories about how the mechanisms triggered by intervention enactment might generate outcomes, referring to examples from a ‘realist trial’ of a whole-school health intervention. Qualitative research can explore mechanisms directly, by asking participants how they think interventions work, or indirectly, by exploring participant experiences of intervention-related actions to …

  • Implementing a whole-school relationships and sex education intervention to prevent dating and relationship violence

    Open AccessRebecca Meiksin, Rona Campbell et al.ARTICLESex Education2020

    Adolescent dating and relationship violence is associated with health harms and is an important topic for sex education. School-based interventions addressing this have been effective in the USA, but schools in England confront pressures that might hinder implementation. We assessed the feasibility of, and contextual enablers/barriers to implementing Project Respect, a whole-school intervention. We conducted a pilot trial with process evaluation …
