Sponsor's own description
It is widely known that physical activity is important for health and wellbeing, yet most Americans do not meet recommended levels of activity. People may commonly believe that only the actual amount of physical activity matters for health and wellbeing. However, the investigators propose that individuals' mindsets about the adequacy of their level of physical activity and its corresponding health consequences (activity adequacy mindsets) affect health outcomes, over and above their actual level of physical activity. In recent years, health technologies such as wearable fitness trackers have become popular tools to promote higher levels of physical activity. This study leverages the tracking and feedback capabilities of Apple Watch to study the effects of mindsets about physical activity on health and wellbeing, as well as the pathways through which these effects may occur.
