| Summary: | Abstract Background Schoolteachers’ personal health and wellbeing are priority to ensure quality teaching, positive student outcomes and improving teacher retention. With limited-availability of validated tools to measure teacher food and nutrition (FN) as a component of wellbeing, this study aims to evaluate the content validity of the Teacher Food and Nutrition-related health and wellbeing Questionnaire (TFNQ) to fill this gap. Method A two-round Delphi was used to refine the questionnaire and establish content validity. Round-one reviewed constructs and lifestyle covariates (LC) for inclusion. Round-two considered construct phrasing, appropriateness of scales and questionnaire order. Descriptive and thematic analyses were conducted. Results Round-one included 23 international experts, with 19 also participating in round-two. After round-one, seven constructs and three LC were removed with two constructs revised into four concise new groupings to refine the TFNQ. In round-two 83% of experts agreed with questionnaire order, and feedback indicated only minor adjustments. The final TFNQ contains 26 FN and wellbeing constructs and three LC. Conclusion This Delphi study established content validity of the TFNQ to appropriately measure key aspects of FN as a component of wellbeing in schoolteachers. Future testing will evaluate the TFNQ construct validity and reliability. |
