Use data from a published validation study concerning retention interval and school foodservice production records to examine intrusions (uneaten items reported eaten) in the school-meal parts of 24-hour recalls. For that study, children were observed eating two school meals (breakfast, lunch) and interviewed under one of six conditions from two target periods (previous day [PDTP], prior 24 hours [24TP]) crossed with three interview times (morning, afternoon [AIT], evening). For this article, a catalog was constructed of foods available for that study’s school meals. That study’s intrusions were classified as stretches (on children’s meal trays but uneaten), internal confabulations (in children’s school foodservice environments for that meal but not on children’s trays), or external confabulations (not in children’s school foodservice environments for that meal). Occurrence, types, and amounts of intrusions were investigated. Six schools; 60 fourth-grade children (10/condition). For breakfast, for the 24TP versus PDTP, reported items were less likely to be intrusions, internal confabulations, and external confabulations; and intrusions were more likely to be stretches. For lunch, for the 24TP-AIT condition versus the other five conditions, reported items were less likely to be intrusions and external confabulations. Mean amounts reported eaten were smaller for stretches than internal confabulations or external confabulations at breakfast, and for stretches than internal confabulations at lunch. Accuracy was better for the 24TP (with fewer intrusions of which proportionally more were stretches which had smaller amounts reported eaten) than PDTP. Studies with 24-hour recalls should minimize retention interval to improve accuracy.
