Recent technical developments present new ways to track and reflect upon behaviours related to a healthier lifestyle. For example, individuals can use their smart phones or other interactive devices to measure and alter physical activity or dietary choices. In the proposed project, a recently developed wearable camera is used to gather information on factors that could trigger one?s alcohol use. By doing so, we will set the first step in testing the extent to which lifelogging (the process of tracking personal data generated by own behavioural activities) can be used as input for tailor-made applications to reduce alcohol use. Exposure to alcohol-related cues (e.g., alcohol marketing) has been associated with individual?s drinking levels (i.e., cue-reactivity) in controlled lab settings. Little is known about how cue-reactivity affects individual?s drinking in every-day life contexts. The current project examines the potential value of a wearable automatic camera that unobtrusively captures a picture every 30 seconds, to assess cue-reactivity outside the laboratory. The use of this innovative product makes it possible to follow the user throughout the day and potentially capture the cues that could trigger alcohol consumption. The aim is to examine whether we could establish correlations between alcohol-related cues and subsequent drinking behaviour in ecological-valid settings, providing evidence on the effectiveness of wearable technology to assess cue-reactivity. If cue-reactivity is established, this information will lay foundation for larger collaborative research grants in which wearable technology is used to track and alter one?s substance use related behaviours.
