 Two commercials will be prepared for the schools using messages developed for this age group that feature children as the main characters. This approach captures the potential influence of peers. Potential 3-5th grade actors and adult actors will be recruited from local dramaplayhouse venues. The two commercials will be shown each week in alternating weeks for a total of four weeks. Example: Week 1, commercial A shown; Week 2, commercial B shown; Week 3, commercial 1 shown; Week 4 commercial B shown. Child actors will likely not attend the test schools, but they and their parents will be informed that the commercials will be shown in two Alachua County Public Schools. Children will include an equal mix of girls and boys and approximately half of the children will be from racialethnic minority groups that are represented in the Alachua County school system. These videos will be created using existing video production facilities at the University of Florida.
