Web-based graphical food frequency assessment system: Design, development and usability
The acceptability of an online food frequency questionnaire (FFQ) amongst users participating in the Eat Well Kuwait Project (EatWellQ8) was good, while the results for mobile devices were comparable with computers (Zenun et al., 2017). These conclusions were reached as part of study examining how online tools might be best used to assess food intake.
FFQs used photographs of different portion sizes for each food to make it easier for users to indicate how much they usually eat. In total, volunteers were asked to specify consumption frequency of 146 foods including drinks. Usability scores were good (75) and completion took just over 14 minutes.
EatWellQ8 aims to determine if web-based and face-to-face communication of personalised nutrition are equally effective in Kuwait. These results correspond to the first part of a study related to the design and development of the online FFQs and will help design of a web-based tools and their acceptability.
