This research article, published in the British Journal of Nutrition, provides empirical data on the cost and cost-efficiency of conducting a 24-hour dietary recall using the INDDEX24 mobile app in comparison to a traditional pen and paper data collection approach. Learn about the potential cost-savings associated with using INDDEX24 here.
The INDDEX24 mobile app is a technology assisted data collection tool that allows for quantitative 24- hour dietary recall survey data to be collected (following the conventional multi-pass method) on mobile devices, thereby eliminating the need for a separate data entry process to be required. Within the INDDEX24 mobile app, there is also functionality to undertake some aspects of data processing, thereby enabling real-time monitoring of the quality of data collected. The app was developed to be appropriate for global use.
