Feasibility study of Learning Together for Mental Health: fidelity, reach and acceptability of a whole-school intervention aiming to promote health and wellbeing in secondary schools.

Background: Despite high rates of adolescent mental health problems, there are few effective school-based interventions to address this. Whole-school interventions offer a feasible and sustainable means of promoting mental health, but to date, few have been evaluated. Previously we trialled the Learning Together intervention comprising local needs assessment, student and staff participation in decision-making, restorative practice, and a social and emotional skills curriculum. This was effective not only in preventing bullying (primary outcome) but also in promoting mental well-being and psychological functioning (secondary outcomes). We adapted Learning Together to develop Learning Together for Mental Health, focused on promoting mental health.

Objective: This paper reports on quantitative data on intervention implementation fidelity, reach and acceptability to assess progression to a Phase III trial.

Design: We drew on student baseline and follow-up surveys and an integral process evaluation from a non-randomised feasibility study involving four secondary schools.

Setting: Southern England.

Participants: Students in year 8 (age 12/13) at baseline and year 10 (age 14/15) at follow-up and school staff and students and intervention trainers and facilitators completing process evaluation tools.

Interventions: Whole-school intervention featuring student needs assessment, action groups involving staff and students which selected actions from an evidence-based menu, restorative practice to improve relationships and address student behaviour and a social and emotional skills curriculum.

Results: Restorative practice training was implemented with fidelity in all schools. Curriculum training was implemented with fidelity in three of four schools. The response rate to the needs survey across the three schools that participated was 79%. Action groups were implemented with fidelity. Action groups at all four schools completed at least one locally decided action and chose at least one action from the menu of evidence-based options. Restorative practice was implemented across all schools. Of lessons that were observed and lessons for which teachers returned logbooks, curriculum delivery was implemented with fidelity. However, two schools delivered 50% or less of the recommended lessons, and not all teachers completed logbooks. All students and staff completing surveys reported finding the Learning Together for Mental Health intervention a good way to promote student mental health. Over a third of students reported definite awareness of actions being undertaken by their schools to improve student mental health. All pre-defined progression criteria to proceed to a Phase III trial were met. The intervention was delivered with good fidelity and had strong acceptability.

Limitations: The schools involved may not be representative of those which we would recruit to a Phase III trial.

Conclusions: The study met all pre-determined progression criteria, and the intervention is ready for a Phase III trial with minor adaptations.

Future work: A Phase III trial of effectiveness is justified.
