Validation of a Brief Questionnaire Against Direct Observation to Assess Adolescents' School Lunchtime Beverage Consumption.


ABSTRACT: OBJECTIVE:Beverage consumption is an important determinant of youth health outcomes. Beverage interventions often occur in schools, yet no brief validated questionnaires exist to assess whether these efforts improve in-school beverage consumption. This study validated a brief questionnaire to assess beverage consumption during school lunch. METHODS:Researchers observed middle school students' (n = 25) beverage consumption during school lunchtime using a standardized tool. After lunch, students completed questionnaires regarding their lunchtime beverage consumption. Kappa statistics compared self-reported with observed beverage consumption across 15 beverage categories. RESULTS:Eight beverages showed at least fair agreement (kappa [?] > 0.20) for both type and amount consumed, with most showing substantial agreement (? > 0.60). One beverage had high raw agreement but ? < 0.20. Six beverages had too few ratings to compute ?'s. CONCLUSIONS AND IMPLICATIONS:This brief questionnaire was useful for assessing school lunchtime consumption of many beverages and provides a low-cost tool for evaluating school-based beverage interventions.
