A comparison of the Don't Stop! Game and the Step it <scp>UP</scp> ! Game to increase step counts of adults with disabilities

The Step it UP! Game, a modified version of the Good Behavior Game (GBG), has previously been shown to increase physical activity levels among elementary school children and adults with disabilities. The purpose of this study was to compare a novel modification of the GBG targeting physical activity, the Don't Stop! Game, with the Step it UP! Game. Participants included 14 young adults with intellectual and developmental disabilities. Three conditions were alternated randomly within a multielement design: baseline, Step it UP! Game (in which the team with the most steps wins a prize), and Don't Stop! Game (in which the team with the fewest demerits for standing still wins a prize). All 14 participants had higher steps per minute during intervention conditions relative to baseline, but the degree of difference between intervention conditions differed across participants. The Don't Stop! Game was preferred by more participants.
