Who uses food barcode scanner apps and why? Exploration of users' characteristics and development of the Food Barcode Scanner App Questionnaire

Résumé

Food barcode scanner apps (FBSAs) are increasingly being used to verify food quality. By scanning a product's barcode, they can provide a range of information, including nutritional quality or information on the toxicity of food components. Although they seem to be widely used, no study has yet examined their use in the general population. The objectives of this study were therefore twofold: (a) to identify who the users of FBSA are and (b) to evaluate behaviours and cognitions associated with use of these apps through the development and validation of the Food Barcode Scanner App Questionnaire (FBSAQ). Method A total of 1626 women (average age of 37.51 years; SD = 12.67) from the general population were included in this study, with 25.7% reporting themselves as using at least one FBSA. Participants completed questionnaires assessing socio‐demographic and health characteristics, the use of health apps and the FBSAQ, when relevant. Results The users of FBSAs did not differ from nonusers in regard to key socio‐demographic characteristics, but they were more likely to use healthcare services and other health apps than nonusers of FBSAs. Psychometric analyses allowed validation of the FBSAQ through three factors: pathological use, dietary concerns and exclusion of unhealthy components. Conclusion Data showed that the use of FBSAs can be beneficial for many individuals, as they help with food choices. However, some user may develop more problematic behaviours and have difficulties in not using these apps.
