Summary:The purpose of this study was to develop tests for measuring nutrition knowledge and diet-health awareness using items appearing in the 1989-1991 Diet and Health Knowledge Surveys. The development and evaluation of these tests relied upon estimates of their reliability and their discriminant, convergent, correspondence, and representative validity. The reliability estimates for the 23-item nutrition knowledge test were less than 0.70 for all three surveys. The reliability estimates for the 27-item diet-health awareness test were greater than 0.70 for all three surveys. Both tests received support for discriminant and convergent validity. The correspondence validity of both tests with three measures of dietary quality was low. Implications are made for further research on tests of nutrition knowledge and knowledge structures and for the relationships of these constructs to dietary behavior.
