  • Engagement with and Acceptability of a School-based Relationships and Sexual Health Intervention

    Open AccessRebecca Meiksin, Ruth Ponsford et al.ARTICLESexuality Research and Social…2026

    Evidence suggests that school-based relationships and sex education plus school-level actions may be effective in promoting sexual health. We conducted a trial of a relationships and sexual-health intervention in English secondary schools. We draw on nested qualitative research to explore student engagement and acceptability. Twenty-four intervention schools participating in a randomised trial delivered a two-year programme aiming to comprise cla…

  • 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…

  • Understanding the limited effectiveness of a whole-school relationships and sexual-health programme

    Open AccessVeena Muraleetharan, Ruth Ponsford et al.ARTICLESex Education2026

    Previous trials of whole-school relationships and sexual-health programmes have not reported on fidelity, reach or acceptability, despite the importance of these factors for interpreting outcomes. Our trial of the Positive Choices whole-school relationships and sexual-health programme found limited effectiveness in secondary schools in England. We aimed to understand whether sub-optimal fidelity, reach or acceptability might explain the results. …

  • Effects of a whole-school relationships and sexual health intervention on non-competent sexual debut

    Open AccessRuth Ponsford, Rebecca Meiksin et al.ARTICLEJournal of Epidemiology and…2026Cited by: 1References: 22

    BACKGROUND: Relationships and sex education (RSE) impacts some sexual behaviours but could be strengthened by incorporating whole-school approaches (eg, building engagement, providing contraception). These can prevent pregnancies and sexually-transmitted infections but are unevaluated in UK schools. METHODS: A cluster-randomised trial of 'Positive Choices' compared it with usual practice in English secondary schools. Intervention comprised: RSE, …

  • The mechanisms by which a whole-school intervention might improve sexual health

    Open AccessRuth Ponsford, Rebecca Meiksin et al.ARTICLESocial Science & Medicine2025References: 17

    Whole-school interventions go beyond classroom education, promoting health by modifying school environments. These can be effective in delaying sexual debut and increasing contraception use but mechanisms are poorly understood. Qualitative research within realist evaluation can explore mechanisms via building 'context-mechanism-outcome configurations', describing how interventions trigger mechanisms that interact with context to generate outcomes…
