Dr. Suzanne Baxter, recipient of the 2017 Monsen Award for Outstanding Research Literature, and a key colleague, Dr. Alfred Smith, will review findings and practice applications from a systematic research program on factors that influence children’s dietary recall accuracy. The National Institutes of Health and the United States Department of Agriculture funded validation studies which assessed children’s recall accuracy for school-meal intake, usually within 24-hour recalls, by comparing intake reported by children to direct observations of their school-meal intake. Experimental manipulations identified such influences on recall accuracy as retention interval and interview prompts. Relationships to recall accuracy of such child variables as cognitive ability, social desirability, body mass index, and socioeconomic status were examined. Analyses unmasked hazards when evaluating accuracy for kilocalories and macronutrients without first considering the accuracy of items and amounts reported.

Learning Objectives:

  • Demonstrate why validation studies are the optimal method to assess the adequacy of dietary reporting methods and modifications to those methods; and to define matches, omissions, and intrusions.
  • Identify one strategy to apply to their research or practice to enhance the accuracy of dietary recalls by children.
  • Explain the relationship of children’s reporting accuracy in 24-hour dietary recalls to at least one child-respondent.

Learning Need Codes:

  • 9060 – Research development, design
  • 3010 – Assessment methodology
  • 3020 – Assessment of target groups, populations

Performance Indicator:

  • 10.2.1 Identifies and selects valid and reliable tools to conduct a comprehensive nutrition assessment.
  • 6.1.4 Collects qualitative and quantitative data using mixed methodologies and interprets information.
  • 6.3.4 Defines and establishes appropriate measurements and evaluations.
