Plain English Summary

Background and study aims
Pupil attendance in schools is a matter of great concern in England and Wales. While the reasons for school absence are complex, bullying, lack of safety at school, and school conflict are among them. The Grassroots programme aims to improve school attendance by reducing conflict and bullying behaviours in schools.

Who can participate?
Young people in school years 7-9 attending mainstream state-funded secondary schools in the recruitment areas.

What does the study involve?
Pupils in the treatment group will complete a survey in which they identify pupils they have chosen to spend time with. The best-connected pupils in each school will be invited to join a Change Makers group and attend 10 fortnightly intervention sessions with a facilitator to develop anti-conflict interventions tailored to their school. This will include handing out wristbands for engaging in friendly or anti-conflict behaviour, displaying posters with anti-conflict messages, sharing anti-conflict messages online, modelling pro-social behaviours and talking with peers about how to reduce conflict.

What are the possible benefits and risks of participating?
It is hoped that being part of a Change Makers group will be enjoyable and may improve pupils' experiences of school. Being part of a Change Makers group will mean missing a small number of lessons (10).

Where is the study run from?
The Grassroots programme is being run by a team from Behavioural Insights Limited (UK). Regional facilitators will lead Change Makers sessions in schools.

When is the study starting and how long is it expected to run for?
January 2023 to January 2027

Who is funding the study?
1. Youth Endowment Fund (UK)
2. Education Endowment Foundation (UK)

Who is the main contact?
1. Dr Becky Taylor (UCL) is the main contact for the evaluation (becky.taylor@ucl.ac.uk)
2. Dr Kathryn Atherton (Behavioural Insights Ltd) is the main contact for the Grassroots programme

Ethics approval(s)

Approved 24/03/2023, IOE Research Ethics Committee (UCL) (20 Bedford Way, London, WC1H 0AL, United Kingdom; +44 (0)20 7679 2000 (switchboard); ioe.researchethics@ucl.ac.uk), ref: REC1773

ConditionImproving school attendance through reduction of conflict and bullying behaviours in 11-14-year-old adolescents in secondary schools in England and Wales
InterventionThe Grassroots programme (adapted from ROOTS, Paluck et al., 2016) will be implemented in schools and randomised on a 1:1 basis. The randomisation procedure placed half of participating schools in each region (North West, Midlands, London, West England and South Wales) in the intervention arm and half in the control. A seed in R was used to generate random numbers for each school (listed alphabetically) and schools with the lowest random numbers in each of the five regions were allocated to the intervention arm.

Pupils in the treatment group will complete a survey in which they identify pupils they have chosen to spend time with. The best-connected pupils in each school will be invited to join a Change Makers group and attend 10 fortnightly intervention sessions with a facilitator to develop anti-conflict interventions tailored to their school. This will include handing out wristbands for engaging in friendly or anti-conflict behaviour, displaying posters with anti-conflict messages, sharing anti-conflict messages online, modelling pro-social behaviours and talking with peers about how to reduce conflict.

The control group is business as usual.
Intervention typeBehavioural
Primary outcome measureSchool attendance is measured as the percentage of school sessions attended in a term from the National Pupil Database (England) and SAIL databank (Wales) at baseline (Autumn term 2023), post-intervention (Summer term 2023), and 1 year (Autumn term 2025)
Secondary outcome measures1. Bullying victimisation, cyberbullying victimisation, bullying perpetration and cyberbullying perpetration are measured using the four subscales of the Bullying and Cyberbullying Scale (for adolescents) at baseline and post-intervention
2. Aggressive behaviour is measured using the Peer Conflict Survey at baseline and post-intervention
3. Emotional symptoms, conduct problems, hyperactivity, peer relationship problems and prosocial behaviour are measured using the five subscales of the Strengths and Difficulties Questionnaire at baseline and post-intervention
4. Peer-to-peer incidents are measured by counting teachers’ disciplinary reports over a term at baseline (Autumn term 2023) and post-intervention (Summer term 2024)
5. Peer-to-peer conflict is measured using the descriptive and prescriptive norms survey at baseline and post-intervention
6. Feeling safe in school is measured using two survey questions at baseline and post-intervention
