Speakers: Suzanne D. Baxter, PhD, RD, LD, FADA, and and David Hitchcock, PhD, University of South Carolina

Learning Objectives:

1. Describe quality control procedures for direct meal observations

2. Describe quality control procedures for interviews

3. Describe differences between the response variables omission rate, intrusion rate, and total inaccuracy

4. Describe whether children’s dietary recall accuracy differed by the following: interview content (diet-only; diet-and-physical-activity), retention interval (same day; previous day), grade (third; fifth), any of their two-way interactions, sex

5. Describe a strength of the validation method of direct meal observations as used in this study
