To examine whether small teams of parent volunteers could validly and effectively deliver the KCP to increase children’s FVFIRST, HDRINK, and EXERCISE behaviors, we used two brief study phases six months after the KCP application at the school: one week of baseline conditions (three days per week), one week of reward conditions (three days per week). We focused only on
children in the 2nd and 3rd grades because they had back-to-back lunch periods, which reduced the total time we asked the parent volunteers to contribute. All 182 children in the 2nd and 3rd grades were given nametags and pedometers to wear at school for two weeks (98 boys and 84 girls; 97 2nd graders and 85 3rd graders). Of the 182 children, 111 (61.0%) children were observed eating the school-provided lunch for at least two of the three meals in both baseline and reward conditions (66 boys and 45 girls; 56 2nd graders and 55 3rd graders).
