3.2. Group Effects. Group effects have been reported previously [41]. The primary finding was that the group assigned to FV↑Sed↓ produced significantly greater change in composite diet-activity improvement score after the 3- week intervention phase, relative to the other three groups (FV↑PA↑, Fat↓PA↑, Fat↓Sed↓). Further, the FV↑Sed↓ group maintained this advantage through the end of the 17-week Follow up Phase.
The effects reported herein related to financial motivation were independent of group assignment. None of the financial motivation x group interactions were significant; thus, all secondary analyses reported in this paper were conducted collapsing across Groups.
