December 8, 2015 updated by: Abby C King, Stanford University
The purpose of this research is to test programs to increase physical activity and reduce sedentary behavior using motivational messages over a cell phone.

Intervention / Treatment

Detailed Description

We want to learn if conceptually-based behavioral interventions for promoting increased physical activity and decreased sedentary behavior via state-of-the-art mobile phones will be efficacious at improving these behaviors relative to commercially available Android applications as a control. If efficacious, these types of intervention programs could be disseminated to a wide variety of sedentary and underactive adults at a relatively low cost. This could have a potentially significant impact on promoting improved health such as reduced obesity, a key problem within the U.S.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Cognitive app
Cognitive app promotes behavior change via goal setting, feedback, and problem solving
Behavioral: Mobile Intervention for Lifestyle Eating/Exercise @ Stanford
Participants are randomized to one of 4 groups, each of which uses a different Smartphone app to promote health behavior change
Active Comparator: Social app
Social app promotes behavior change via social relationships and feedback
Behavioral: Mobile Intervention for Lifestyle Eating/Exercise @ Stanford
Participants are randomized to one of 4 groups, each of which uses a different Smartphone app to promote health behavior change
Active Comparator: Affect app
Affect app promotes behavior change via game-like elements including the use of a bird avatar as a visual representation of one's activities and operant conditioning
Behavioral: Mobile Intervention for Lifestyle Eating/Exercise @ Stanford
Participants are randomized to one of 4 groups, each of which uses a different Smartphone app to promote health behavior change
Active Comparator: Nutrition app
Nutrition app promotes behavior change bvia tracking of food consumption
Behavioral: Mobile Intervention for Lifestyle Eating/Exercise @ Stanford
Participants are randomized to one of 4 groups, each of which uses a different Smartphone app to promote health behavior change
