Plain English Summary

Background and study aims:
Adolescence is a time of change and development. Learning skills that build resilience has the potential to help adolescents navigate these challenges during their time at school and build a platform to serve them throughout their lives. Many secondary schools teach emotional health and wellbeing (ability to deal with life's challenges), believing that it can affect the way children learn, behave, and develop into adulthood. The project will compare existing, good quality social emotional learning that is already being taught in schools (known as ‘teaching as usual’) to a programme of study that is based on mindfulness techniques. The mindfulness programme, called ‘.b’, has been developed by the Mindfulness in Schools Project and is a series of 10 lessons. The lessons are designed to appeal to young people and each one teaches a particular mindfulness skill. Mindfulness is a way of being present to experiences as they happen, rather than worrying about what has happened or might happen in the future. Participating teachers in schools allocated to the mindfulness group will be trained to deliver the programme to pupils. The aim of this study is to determine the impact of the mindfulness programme on the wellbeing of the pupils 2 years after the programme is delivered, but in addition it will look at the impact on teacher wellbeing and stress.

Who can participate?
Mainstream secondary schools in the UK, year 7 and 8 pupils who attend and their teachers.

What does the study involve?
The project will carry out a comparison of social and emotional learning, which is already being taught in schools, with a class-based mindfulness intervention (program). All of the schools participating in the project will carry on with their usual curriculum. However, in half of the participating schools a number of teachers will be trained in mindfulness intervention. Teachers in the mindfulness arm of the project complete a personal eight-week face-to-face mindfulness course. Each weekly session lasts for around two hours and takes place on the school premises after school hours. This is then followed by four-day mindfulness syllabus training. Teachers are then asked to teach the programme to classes of Year 8 and 9 pupils. Headteachers, teachers and pupils are asked to complete questions about their health and wellbeing at the start of the study and at up to a maximum of four further time points over a period of up to 3 years.

What are the possible benefits and risks of participating?
If allocated to the mindfulness intervention group, participating teachers and schools benefit from receiving personal mindfulness training and CPD training. There are no known risks associated with this project.

Where is the study run from?
The study is run from the University of Oxford and takes place in 76 secondary schools in England (UK)

When is study starting and how long is it expected to run for?
June 2016 to December 2021

Study information

Scientific title

A cluster randomised controlled trial of the effectiveness and cost-effectiveness of a mindfulness training programme in schools compared with normal school provision: the MYRIAD trial


MYRIAD (MY Resilience In ADolescents)

Study hypothesis

Mindfulness Training (MT) alongside normal school provision will be more effective and cost effective than normal school provision alone in improving pupils’ self-reported risk for depression; social, emotional and behavioural functioning; and wellbeing, at 2 years follow up.

Mental wellbeing


Randomisation of schools to intervention and control arms (‘Teaching as usual’) will be stratified and will be carried out by an independent statistician. The following stratification variables will be considered, with final decisions taken once schools have been recruited: School size (large/small), type of school (selective/non-selective, independent/non-independent, mixed/single gender, school quality measure e.g. OFSTED), geographic location (urban/rural and region) and level of deprivation (below or above median of children eligible for free school meals).

‘Teaching as Usual’ group: Schools will continue to teach their usual scheduled lessons.

Mindfulness Training group: Schools will be trained in the mindfulness (MT) programme to be included in the school curriculum the following school year. The training programme to deliver the MT programme curriculum involves teachers first participating in an 8-week MBCT programme, adapted for the general (non-clinical) population, to support the development of their resilience and mindfulness skills (eight 2 hour sessions per week, with an all-day mindfulness session supported by a digital app to facilitate mindfulness practice during and after the 8 week course). They will then attend a 4-day training workshop to learn how to deliver the MT in schools.

Schools, teachers and pupil will be followed up for 2 years after the pre-intervention measures.

Intervention type



Drug names

Primary outcome measures

1. Risk for depression is measured using Centre for Epidemiologic Studies Depression Scale (CES-D)
2. Socio-emotional and behavioural functioning is measured using Strengths and Difficulties Questionnaire (SDQ - Pupil)
3. Well-being is measured using Warwick-Edinburgh mental well-being scale (WEMWBS)

Primary outcome measures are for pupils only and will be taken at five times points: Baseline, pre-intervention, three-months post-intervention (or equivalent), one-year (one year after pre-intervention) follow-up, and again at two-year follow-up (two years after pre-intervention).

Secondary outcome measures

1. Students’ executive processing is measured using the Behaviour Rating Inventory of Executive Function, self and teacher rated versions (BRIEF)
2. Peer relationships are measured using the Resistance to Peer Influence Scale (RPIS)
3. Drug and alcohol use
4. Anxiety is measured using anxiety subscales from the Revised Child Anxiety and Depression Scale (RCADS)
5. Strengths and Difficulties Questionnaire (SDQ)
6. Student level attainment is measured using information taken from the National Pupil Database (NPD)
7. Self-harm and suicidal ideation
8. Mindfulness skills are measured using the Child-Adolescent Mindfulness Measure (CAMM)
8. Health-related quality of life is measured using the Euroqol 5D 5 level (EQ-5D-Y)

1. Well-being is measured using the Maslach Burnout Inventory (MBI Educator survey)
2. Self-efficacy is measured using the Teacher’s Self-efficacy Scale (TSS)
3. Classroom mindfulness is measured using the Mindfulness in the Classroom questionnaire
4. Stress is measured using the Perceived Stress Scale (PSS)
5. Depression is measured using the Patient Health Questionnaire (PHQ-9)
6. Anxiety is measured using the Generalised Anxiety Disorder questionnaire (GAD-7)

1. School ecology/climate is measured using sub-scales most relevant to the intervention from the School Climate and Connectedness Survey (SCCS)
2. School level attainment, for example GSCE results, is determined using information taken from the National Pupil Database (NPD)

Study outcomes will be measured at five time points: baseline (school and teacher as well as primary measures for all pupils from Years 7 and 8); pre-intervention; three-months post-intervention (or equivalent); one-year (1 year after pre-intervention) follow-up; and again at two-year follow-up (2 years after pre-intervention).
