What works in wellbeing: a randomised controlled trial of mindfulness in policing

Randomised Control Trial Status


Trial Hypothesis

  • Online training in mindfulness will improve wellbeing, life satisfaction, resilience and performance for police officers and staff (primary outcomes) – accept hypothesis.

  • Online training in mindfulness will reduce sick leave, presenteeism and leaveism (secondary outcomes) – accept hypothesis for reducing presenteeism, do not accept hypothesis for sick leave and leaveism.  

  • Bespoke training aimed at police officers (Mindfit Cop) will improve wellbeing, resilience and performance for police officers and staff more effectively than a generic mindfulness intervention (Headspace) – do not accept hypothesis.

  • Mindfulness training is more likely to be effective for people with high levels of job control in terms of how they structure their day and do their tasks – do not accept hypothesis.

Study Design

All officers and staff in the five forces were invited to take part in the trial. Those who volunteered were randomly allocated to one of three groups (Headspace, Mindfit Cop or a waiting list). This study was a basic randomised design comparing two treatment groups (mindfulness training) to control.


  • Treatment 1:  receives free access to the 'Headspace' app/online course
  • Treatment 2:  receives free access to the 'Mindfit Cop' web app/online course

Outcome Measures

  • Wellbeing - measured using the Short Warwick-Edinburgh Mental Wellbeing Scale (7 items)
  • Life Satisfaction – measured using a single item from the Office of National Statistics personal wellbeing questions
  • Resilience - measured using the Brief Resilience Scale (6 items)
  • Work performance - measured using a question from the WHO HPQ survey
  • Presenteeism and leaveism – measured using custom single items for this study.
