Wearable health technologies are designed to improve a user’s self-awareness of their state of health and increase motivation and physical activity, but there is limited understanding of the psychological and behavioral impact these devices have. The present research attempts to further clarify the influence of individual characteristics on the cognitive, affective, and behavioral outcomes of activity tracker usage, including the development of dependency. A cross-sectional study of 212 college students who used activity trackers was conducted to evaluate the psychological and behavioral impact of activity tracker usage and users’ affective response to their device. Participants expressed more positive affect while wearing their device as opposed to when they were unable to wear it. Female participants exhibited more positive affect than male participants while wearing their device but less when unable to wear it. Only 9% of the sample reported a dependency effect. The dependency effect was negatively associated with intrinsic motivation to be physically active, motivation by the idea of success, and the personality traits of agreeableness and conscientiousness. The dependency effect was positively associated with extrinsic motivation for physical activity and tracker usage, as well as need for cognitive closure. This research elucidates the unintended outcomes of activity tracker usage along with the individual characteristics that present as predictors of these outcomes.
