简要总结
Physical activity has been shown to reduce the risk of chronic diseases and promote physical and mental health and wellbeing, yet few women are active enough to see these benefits. Wearable activity trackers show promise for helping people increase their physical activity levels by supporting self-monitoring. However, few researchers have examined how providing people with these devices impacts physical activity levels, or motivation for physical activity which is a significant and robust predictor of physical activity. Based on previous research, it is possible that women's physical activity levels would be more likely to increase if they received an autonomy-supportive intervention to enhance motivation in addition to a wearable activity tracker. A pilot, three-armed randomized controlled trial was developed to test this hypothesis and to assess if changes in perceived autonomy-support, basic psychological need satisfaction/thwarting, motivational regulations, wellbeing indicators are associated with changes in physical activity over time.
