What processing do recall data entered into ASA24 by respondents undergo?
Recall data are coded using FNDDS, MPED, and NHANES (see FAQ #26). No other processing or quality control measures are conducted. As with any data collection initiative, researchers should carefully assess the quality of the data collected from their study respondents. To assist researchers in assessing data quality, output files (see FAQ #26) include a flag to indicate whether each recall was completed (i.e., whether the respondent completed the program up to and including the last question). However, ‘incomplete’ recalls may be deemed acceptable by a researcher depending upon how far the respondent made it in the program and what data are missing (e.g., in the food module, details on portion size versus a valid response to the final question which queries whether the amount of food consumed yesterday was usual). It is also possible that a researcher may wish to exclude a recall coded as ‘complete’ by ASA24 because the data entered by the respondent are of poor quality or seem implaus
