Claire Garnett is a researcher in the field of alcohol and smoking cessation, both in terms of the use of digital technologies to support behaviour change and the population level influences on these behaviours. Her research is underpinned by behavioural science and theory. She is a psychologist by background, completing her PhD in Health Psychology in 2017 before joining the UCL Tobacco and Alcohol Research Group as a Research Fellow.
A major focus of her research is on digital interventions to reduce hazardous and harmful alcohol consumption. As part of her PhD research, they developed and evaluated a theory- and evidence-based smartphone application – Drink Less – to reduce alcohol consumption, using a systematic and iterative process drawing on evidence and theory to inform its content. Its evaluation in a preliminary trial assessed the effectiveness of individual modules. Based on these findings and user feedback, the app has been updated and improved. The app is being used to provide insights into engagement with digital interventions, predictors of alcohol reduction and what makes an effective digital intervention. She also conducts research to provide insights into population-wide influences on smoking and smoking cessation.
