The web-buffet – development and validation of an online tool to measure food choice

[摘要] AbstractObjectiveTo date, no data exist on the agreement of food choice measured using an online tool with subsequent actual consumption. This needs to be shown before food choice, measured by means of an online tool, is used as a dependent variable to examine intake in the general population.DesignA ‘web-buffet’ was developed to assess food choice.SettingChoice was measured as planned meal composition from photographic material; respondents chose preferred foods and proportions for a main meal (out of a possible 144 combinations) online and the validity was assessed by comparison of a meal composed from a web-buffet with actual food intake 24–48 h later. Furthermore, correlations of food preferences, energy needs and health interest with meals chosen from the web-buffet were analysed.SubjectsStudents: n 106 (Study I), n 32 (Study II).ResultsMeals chosen from the web-buffet (mean=2998 kJ, sd=471 kJ) agreed with actual consumption (rs=0·63, P
