Abstract:
We developed an interviewer-administered NT-FFQ comprising a 125-item semi-quantitative FFQ and a twentyseven-
item eating behaviour survey. The reproducibility and validity of the NT-FFQ were assessed using Spearman
correlations, intra-class correlation coefficients (ICC), and levels of agreement using Bland–Altman and crossclassification
over 2 months (NT-FFQ1 and NT-FFQ2). Validity of foods was evaluated against three 24-h dietary
recalls (24-HR). Face validity of eating behaviours was evaluated through semi-structured cognitive interviews. The
reproducibility of eating behaviours was assessed using weighted kappa (κw) and cross-classification analyses.
