AB  - OBJECTIVES: To assess the validity of the Food Intake Recording Software System 
      (FIRSSt) against observation of school lunch and a 24-hour dietary recall 
      (24hDR); and to test the effects of sequencing, observation and a hair sample as 
      a bogus pipeline on accuracy of dietary report. DESIGN: Six-group design 
      systematically varying sequence of self-report (FIRSSt vs 24hDR), observation of 
      school lunch and hair sample as a bogus pipeline manipulation, with random 
      assignment of participants. SUBJECTS/SETTING: 138 fourth-grade students in 2 
      elementary schools. MAIN OUTCOME MEASURES: Accuracy of reported food consumption 
      was measured in terms of matches, intrusions, and omissions among the FIRSSt, 
      24hDR, and as observed at school lunch. Students also completed self-report of 
      performance with FIRSSt. STATISTICAL ANALYSIS PERFORMED: t tests, Pearson 
      correlations, analysis of variance, factor analysis. RESULTS: When compared with 
      school lunch observation for one meal, FIRSSt attained 46% match, 24% intrusion 
      and 30% omission rates, while a dietitian-conducted 24hDR obtained 59% match, 17% 
      intrusion, and 24% omission rates. FIRSSt attained 60% match, 15% intrusion, and 
      24% omission rates against 24hDR for all meals in the previous day. There was no 
      evidence of sequence of assessment affecting accuracy indicators, but there was a 
      weak effect of school lunch observation on percent intrusions. Obtaining a hair 
      sample reduced the omission rate for FIRSSt vs 24hDR and increased the match rate 
      for 24hDR vs observation, thereby enhancing this as a bogus pipeline procedure. 
      Children generally enjoyed completing FIRSSt. Hispanic children were more likely 
      to report problems using FIRSSt. APPLICATIONS/CONCLUSIONS: FIRSSt is somewhat 
      less accurate than a dietitian-conducted 24hDR. However, this lower-cost 
      procedure provides a promising method for assessing diet among children. 
      Observation of consumption at school lunch may be reactive and artificially 
      increase agreement. Obtaining a hair sample as a bogus pipeline may be a valuable 
      technique for enhancing the accuracy of dietary assessment among children.
