An occupational psychologist wanted to investigate interventions for work-related stress. 120 office workers who reported high levels of burnout were invited to participate in a study investigating the effectiveness of Mindfulness-Based Stress Reduction (MBSR).
To select participants, each worker completed a standardised burnout questionnaire which rated their stress level on a scale from 1 (no burnout) to 15 (severe burnout). From this pool, 45 workers with moderate-to-high scores of 11 or 12 were selected to participate. They were randomly assigned to one of three groups:
One week after completing their respective 8-week periods, all participants completed the burnout questionnaire again. The scores before and after were compared to evaluate changes in burnout levels.
What was the aim of this study?
689 exam-style questions on AQA A Level Psychology Scientific processes. Each one has a worked solution and a mark scheme showing where the marks go.
