Development of the Canadian Eating Practices Screener for Adolescents to assess eating practices based on Canada's...

BACKGROUND: In addition to guidance on food choices, the Canada’s Food Guide 2019 (CFG-2019) provides recommendations to support healthy eating habits. A brief self-administered eating practices questionnaire informed by CFG-2019 recommendations was recently developed and validated among adults, but no such measure is available for adolescents. The objective of this study was to develop and assess the content validity of a self-administered screener to measure eating practices based on CFG-2019 recommendations among English- and French-speaking adolescents aged 10 to 17 years. METHODS: Following a literature review of existing measures and the identification of guiding principles for questionnaire development, a 26-item draft screener was created. The content validity of the draft screener was assessed by an expert panel with expertise in nutrition, eating behaviours, public health and/or questionnaire validation (English n = 13, French n = 7) and through two rounds of cognitive interviews with adolescents (English n = 18, French n = 13). RESULTS: The number of items was reduced from 26 to 12 following review by the expert panel, and further reduced to 11 after the cognitive interviews with adolescents. Minor wording changes were made to improve clarity of a few items. CONCLUSIONS: This study resulted in the development of the 11-item Canadian Eating Practices Screener for Adolescents/Questionnaire court canadien sur les pratiques alimentaires des adolescents designed for use among adolescents aged 10 to 17 years. Further work is needed to test the screener for construct validity and reliability. After which, this measure can be used for research and nutrition surveillance of eating practices among adolescents living in Canada.
