Counterfactual Strategies, Physical Activity, and Wearable Trackers

Study Summary

Physical activity (PA) has been suggested to lower one's risk of developing cancer, type 2 diabetes, and cardiovascular disease. While there are benefits from engaging in PA, many people do not engage in enough daily PA, thus increasing the chance of developing non-communicable diseases (NCD). Some NCDs, such as type 2 diabetes, have been shown to occur at higher rates within under-resourced populations, such as low socioeconomic status (SES) communities. Among low-SES communities, external barriers, such as cost and the surrounding physical environment, have been shown to impact engagement in PA. A multi-level PA intervention could be beneficial to help lower NCD health outcomes within at-risk groups, as well as serve as a means to further understand the barriers impeding a healthy lifestyle. At the individual level, past behavior is suggested to be a significant predictor of future behavior. When faced with a NCD diagnosis, one might think about the past and how things could have turned out differently (i.e., counterfactual thinking). For instance, what if a different action had been taken (e.g., "If only I had taken the stairs more at work")? Counterfactuals can also serve as a way of identifying causal links (e.g., "If only there were more green spaces in my area..."). Counterfactuals (CF) on behaviors that can be acted on can facilitate future behavior change by increasing intentions, motivation, and self-efficacy. In this way, CFs might help with 1) breaking a habitual sedentary cycle and 2) identify causal pathways of barriers impacting PA engagement. While preliminary data in the investigators lab suggests that CF strategies are relevant for heightening contemplation to change behaviors and intentions to change behaviors its impact on motivation and self-efficacy remains unknown. Additionally, these preliminary studies were conducted using small, undergraduate student sample, thus generalizability to low-SES individuals living in the surrounding community i

Primary Outcome

As per the description by Fitbit, "...earn Active Zone Minutes for time spent in the fat burn, cardio, or peak heart-rate zones. To help you maximize your time, you earn 2 Active Zone Minutes for each minute you're in the cardio or peak zones. Heart-rate zones are personalized based on your fitness level and age." The tracker will record when the participant enters each personalized target heart rate zone. The Fitbit device automatically adds up the Active Zone Minutes per day and per week. The
