To see if the KCP could improve home-packed lunchess (with more FV included) and children’s consumption of healthy foods (with more FVFIRST and HDRINK), we conducted three lunch
observations of home-packed lunches during the second month of reward conditions to compare the behavior of children in the control and KCP groups. Two trained lunch observers served as
‘‘packer observers’’ for the children present for these three observations, with inter-observer reliability measured by having them simultaneously observe 24 children with home-packed
lunches to record (NO/YES) whether the parent had packed FV, and to record (NO/YES) whether the child showed FVFIRST and HDRINK behaviors. The ‘‘packer observers’’ demonstrated 100% agreement
for all three measures.
