What is being tested?

The study tests if getting text messages about the good feelings you get from exercise can help people become more physically active. It's a micro-randomized trial where participants receive different types of motivational texts.See study design

What are the potential side effects?

Since this intervention involves receiving motivational text messages and increasing physical activity, there are no direct side effects like with medications. However, increased activity could lead to typical exercise-related discomfort.

Experimental Treatment

Group I: Affective Rewards MessagesExperimental Treatment1 Intervention

Throughout the study, each week participants will be asked to plan two exercise sessions for the upcoming week, and will be asked to report on how they did with those plans at the end of the day when they planned to exercise. At the very beginning of the time window when they planned to exercise participants will be randomized with 40% probability to receive no message, 20% probability to receive a reminder to fill out the study questionnaire at the end of the day, and 40% probability to receive one of two types of affective rewards messages (active intervention). The two types are: 1) low-reflection messages written by participants at the beginning of the study, about the affective rewards of exercise they have previously experienced; and 2) high-reflection messages that prompt participants to reflect on the affective rewards of exercise and text back a response.
