To measure acceptability of KCP components and options according to school staff, a brief and anonymous questionnaire was distributed at the end of the three-month KCP application to 31
school staff members (such as the principal, school secretary, school nurse, cafeteria staff, custodians, and 1st–4th grade teachers). School staff were asked to rate the acceptability of
various program features using a five-point scale (from 1 = not at all to 5 = very much). To estimate costs of the Kid’s Choice Program in U.S. dollars per child per month of application, we recorded expenses for the primary supplies needed, which included the nametag necklaces, the pedometers, and the small prizes used for Reward Day.
