The reliability and validity of a Dutch questionnaire on fat consumption as a means to rank subjects according to individual fat intake.
In this paper a short, 25-item, telephone-administered questionnaire, designed to rank individuals according to their dietary intake of fat, is presented. Based on two studies of 52 and 639 men and women, respectively, its relative validity regarding a 7-day diet record and its reproducibility are discussed. A Pearson correlation of 0.59 was observed between fat intake estimated by 7-day diet records and fat score derived from the short questionnaire. Gross misclassification, defined as disagreement between the two fat consumption assessments beyond an adjacent tertile, was 15.4%. A Pearson correlation of 0.71 was calculated by a test-retest procedure. It is concluded that the Dutch short questionnaire on fat consumption is a rapid, simple and inexpensive method that can very well be used in nutrition education research to rank individuals according to their dietary fat intake.
