Title:
Development of a nutriton knowledge questionnaire for obese adults

Objective:
Develop a questionnaire for assessing nutrition knowledge among obese adults.

Methods and results:
The first draft of the questionnaire was based on a literature review. To ensure content validity and expert-assessed face validity, an expert panel examined the questionnaire. The questionnaire was tested for user-friendliness and ambiguity by five students, and thereafter pilot tested in 33 obese adults. The results were analysed for item difficulty, internal consistency and comments made by respondents. Two student groups (n=27), differing in nutritional expertise, answered the questionnaire twice to test construct validity and test-retest reliability. Internal consistency of the three first sections together was 0.84 (Cronbach’s a), and test-retest reliability for all sections together was 0.82 (Pearson’s r). Nutrition students scored significantly better than construction students (p

Conclusion:
The knowledge questionnaire had a satisfactory content-, face- and construct validity and a good reliability. The questionnaire should provide a useful tool for measuring nutrition knowledge among obese adults.
