Text Messaging Study


Many text-message based technology have been used for health behavior change. However, the reasons for success and failure of those systems are unclear. This project was started with the goal of understanding the factors that might affect the persuasive power of text messages for behavior change. The factors of interest were: 1) The sender of the text messages, 2) Text message tailoring to the level of motivation of people, and 3) Text message technology.The results suggest: 1) text messages are useful for encouraging physical activity 2) tailored text messages are better in encouraging physical activity than non-tailored 3) Both automated text messages & text messages from friends/family have positive impact on physical activity.
