Jennifer Murray graduated with BSc. (Hons) in Actuarial Science and Risk Management from Queen’s University Belfast in 2014 and began a PhD programme in September 2014 at the Centre of Public Health. Her main areas of interest are in methods of statistical modelling and analyses. Using statistical techniques, the project aims to investigate the psychological, social and environmental causal mechanisms by which a complex workplace intervention (Physical Activity Loyalty scheme; PAL scheme) induces physical activity behaviour change. The project will also investigate whether these processes differ for initiation and maintenance of behaviour change, and whether the intervention is more effective for subgroups of the study population. This knowledge can aid the improvement of physical activity interventions in future. This research should be of interest to policymakers, clinicians, or other researchers looking to find out more about how to encourage the initiation and maintenance of good physical activity behaviours.
