Validation Information: Short FFQ (Legume)

Papadaki 2007

Relative validity and utility of a short food frequency questionnaire assessing the intake of legumes in Scottish women

Objective: To validate a five-item, semi-quantitative, short food frequency questionnaire (SFFQ) designed to estimate daily legume consumption over a week, against results obtained from 7-day food diaries (7-day FD).

Design: Participants completed a 7-day FD and at the end of this period completed the SFFQ, to indicate the number of times they ate five legume-containing dishes in the previous week and what size portion of each dish they consumed. Daily legume intake (g day-1) was calculated for both methods and participants were classified into tertiles of intake for each method.

Subjects/setting: Fifty-one healthy females aged 25-55 years, employed at the University of Glasgow, Scotland, UK between May 2003 and December 2004.

Results: The two methods produced a similar mean intake of legumes [SFFQ: 14.8 (95% CI: 9.9-19.8) versus 7-day FD: 14.9 (95% CI: 9.3-20.6) g day-1] and the Pearson's correlation coefficient was 0.353 (P = 0.038). Exact agreement within tertiles and gross misclassification were 54.9% and 9.8% respectively. The weighted kappa statistic indicated fair agreement between the two methods (κ = 0.262).

Conclusions: The SFFQ is an acceptable instrument for estimating legume consumption over a week and can be used to rank individuals according to the intake of this food group in similar nutrition intervention studies.
