Abstract

The primary aim of this study was to create a condensed short-form version of the structured interview named the Diet and Health Knowledge Survey (DHKS 1994-1996) via factor analysis. Data from 5765 participants of the 1994-1996 Diet and Health Knowledge Survey were used in the factor analysis. Appropriate sampling weights were used in the multivariate analyses (n=5233) that compared subgroups (i.e., ethnic group, sex, etc.) on the subscales of the DHKS. A 50-item, 12-factor condensed version of the 149-item original DHKS was derived from the analyses. Multivariate analyses, using age and education as covariates, indicated significant differences in dietary beliefs, practices, and behaviors for individuals of different ethnic groups, sex, dieting status, and BMI. Based on our analyses, the condensed short-form version of the Diet and Health Knowledge Survey appears to be a convenient and efficient tool, used in sections or in its entirety, for examining various dietary practices and beliefs of adults. The results from analysis of the short-form DHKS indicate that although a very large proportion of adults in the U.S. are overweight or obese, only a small proportion report current dieting. Examination of the DHKS indicates that although adults varied in their dietary beliefs and practices, dieters tended to report healthier dietary practices and attitudes than non-dieters. BMI level was positively related to self-reported amount of fat, cholesterol, and calories consumed.
