#LOGIC MODEL FOR TEENAGE PREGNANCY TRIAL#

The criteria for progression to a phase III trial were met. Linkage to birth/abortion records was feasible although none occurred among participants. Student surveys indicated 80% acceptability among those who reported awareness of the programme and interviews with staff suggested strong acceptability. With the exception of the parent materials, the fidelity target for implementation of essential elements in three out of four schools was achieved. Response rates to the survey were above 80% in both arms at both baseline and follow-up. ResultsĪll six schools were successfully randomised and retained in the trial. Survey data from female students were linked to records of births and abortions to assess the feasibility of these constituting a phase III primary outcome. Process evaluation data included audio recording of staff training, surveys of trained staff, staff log books and researcher observations of intervention activities. Follow-up surveys were completed 12 months later. Baseline surveys were conducted with year 8 (aged 12–13) in June 2018.

The intervention comprised a student needs survey a student/staff-led school health promotion council a classroom curriculum for year-9 students (aged 13–14) whole-school student-led social-marketing activities parent information and a review of local and school-based sexual health services. Pilot RCT with integral process evaluation involving four intervention and two control schools in south-east England.

Our aim was to assess the feasibility and acceptability of the intervention and trial methods in English secondary schools against pre-defined progression criteria (relating to randomisation, survey follow-up, intervention fidelity and acceptability and linkage to birth/abortion records) prior to carrying out a phase III trial of effectiveness and cost-effectiveness. We developed and pilot trialled Positive Choices, a new whole-school social marketing intervention to address unintended teenage pregnancy and promote sexual health. However, such interventions have not been rigorously trialled in the UK and it is unclear if they are appropriate for delivery in English secondary schools. Both whole-school and social-marketing interventions are promising approaches to addressing these aims. Reducing unintended teenage pregnancy and promoting adolescent sexual health remains a priority in England.
