The purpose of this thesis study was to evaluate the criterion validity and test-retest reliability of an interactive educational tool, referred to as the Rethink Your Drink (RYD) Checklist. This checklist was created to raise awareness of children’s consumption of sugar-sweetened beverages (SSB) among parents/caregivers. Participants of this study included parents/caregivers of young, school-aged children (ages 6-12). This checklist will be incorporated into an educational booklet that will be used to further strengthen the RYD Nevada program. The goal of RYD Nevada is to promote healthful beverages and to reduce the consumption of SSB among households that are eligible or are enrolled in the Supplemental Nutrition Assistance Program. A descriptive design was employed to address the research objectives. Ninety parents/caregivers of young, school-aged children that were able to read and speak English were recruited from the waiting room of the University of Nevada School of Medicine (UNSOM) Family Medicine Center in Reno, Nevada in August 2018. Participants were asked to complete two surveys, one in-person and another by mail two weeks later (referred to as time one and time two). A total of 64 (71.1%) participants completed both surveys. Criterion validity was determined by comparing the mean number of different types of SSB consumed on a typical day as reported by parents/caregivers described on the RYD Checklist against the mean volume of SSB consumed per day as estimated by the BEVQ-15. Test-retest reliability was assessed by comparing responses reported on the RYD Checklist at time one versus time two. The results revealed that the mean number of different types of SSB consumed daily as reported by the RYD Checklist at time one was positively correlated to the mean volume of SSB consumed per day as described by the BEVQ-15 (r=0.6; P<0.05). The mean number of different types of SSB consumed daily on the RYD Checklist at time one and time two were also positively correlated (r=0.8; P<0.05). In conclusion, this study provides evidence of criterion validity and test-retest reliability of the RYD Checklist. Future studies are needed to determine the validity and reliability of the RYD Checklist among a larger more generalizable samples as well as the extent in which the checklist raises awareness of children’s intake of SSB among parents/caregivers.
