Using personalised avatars in a weight loss management programme: participants’ perspectives

Abstract

Abstract Background Obesity interventions rely predominantly on managing dietary intake and/or increasing physical activity but sustained adherence to behavioural regimens is often poor. Avatar technology is well established within the computer gaming industry and evidence suggests that virtual representations of self may impact real-world behaviour, acting as a catalyst for sustained weight loss behaviour modification. We explore patient's experiences of using an avatar as an adjunct to a weight management programme. Methods Exploratory, qualitative research design with a sub sample of participants to explore uncertainties and develop intervention optimisation and conduct of a future trial. Semi-structured interviews, with a purposive sub sample of obese and overweight patients a undergoing weight management programme (n = 12) from two settings in West Yorkshire, England (November-March 2020). Ethical approval was granted. Data were analysed using framework approach of verbatim transcripts. Results Three main themes emerged through data analysis (i) avatar appearance (ii) added benefits and (iii) areas of development. Visual perception of the personalised avatar could positively or negatively influence current and future realities. Patients generally found that using a personalised avatar provided added motivation to continue with the weight management programme and increased their confidence in their ability to work towards a healthy lifestyle to reduce weight loss. Several areas of development were identified for both the weight loss programme and the personalised avatar in relation to accessing psychological support and ways of developing and strengthening their own personal resilience. Conclusions The findings suggest that using personalised avatars could be a useful technique to increase engagement, motivation and adherence to weight loss management programmes among individuals who are obese or overweight. Key messages There appears to be some added motivational benefits to using personalised avatars. Virtual representations of self may impact real-world behaviour, acting as a catalyst for sustained weight loss behaviour.
