For FVFIRST and HDRINK, behavior change was calculated as the mean number of six meals the behavior occurred in reward conditions, minus the number of six meals the behavior occurred
in baseline conditions. For EXERCISE, behavior change was calculated as the mean number of pedometer steps per month in reward conditions, minus the number of steps permonth of baseline
conditions. Results revealed an value of .10 (F = 3.00, p = .035), meaning that the set of three behaviors explained 10%o fBMI% changes for overweight children.More specifically, changes
in the overweight children’s EXERCISE (measured with pedometers) was unrelated to the changes in their BMI% scores (beta = .034, p = .743). Also surprising was the finding that the more overweight children increased their FVFIRST behavior, the more their BMI% increased from baseline to the end of the KCP application (beta = .316, p = .006). In contrast, the more overweight children increased theirHDRINK choices, the more theirBMI% decreased from baseline to the end of the KCP application.
