Description
Summary:Background An assessment of how users rate physical activity apps of varying behavior change technique content is necessary to understand if users recognize differences in an app’s ability to promote physical activity. Objective The purpose of this study was to compare user ratings of an app with a lower behavior change technique count to an app with a higher behavior change technique count. Method Participants were randomly assigned to interact with either the high behavior change technique app or the low behavior change technique app using an iPad. Participants then completed a Mobile App Rating questionnaire. Results The final sample included 83 participants with an average age of 22.66 years (SD = 2.13; range = 20–29). Independent t-tests revealed significant group differences for perceived impact, t(81) = 5.27, p
