Personal profile


After receiving my BSc (Hons) Psychology at the University of Leeds, I then completed an MSc Health Psychology at Coventry University. I am currently completing my PhD by Publication at Coventry University. My PhD, titled ‘The role of self-efficacy in changing lifestyle physical activity behaviour’, is due for submission in February 2015. I have worked as researcher since 2007, firstly as a Research Assistant and more recently as a Research Fellow. My area of research has been physical activity and obesity intervention development, with a specific focus on the role of self-efficacy. I have published systematic reviews that have aimed to identify which behaviour change techniques are most effective at changing both self-efficacy and physical activity behaviour. As a result I was also involved in developing the CALO-RE (Coventry Aberdeen LOndon – REfined) behaviour change techniques taxonomy. I have also worked on a MRC-funded randomised controlled trial of a walking intervention delivered in general practice.

Research Interests

Physical Activity and walking ; Health behaviour intervention development ; Psychological mediators of behaviour change

Vision Statement

My research stems from my general interest in health-related behaviour, with a specific interest in understanding the reasons why people participate in healthy and unhealthy behaviours. This has inspired my research into understanding how to change both the determinants of health behaviour and behaviour itself, particularly physical activity, and the subsequent integration of this knowledge into the development of behaviour change interventions for the general population. I hope to conduct this work with different populations, and for different behaviours, in my future research to build an evidence-base of effective behaviour change techniques.
