Miller, and Achterberg (2000) constructed a multiple choice questionnaire to asses the nutrition and food label knowledge among women with type 2 diabetes mellitus who aged from 40 to 60 years. The questions were placed from the easier to the hard so as to foster confidence among the participants. The questions that measure the factual knowledge were placed in the beginning followed by the more difficult questions (procedural knowledge). The test was designed to be completed within 30 to 40 minutes by most respondents. The reliability of the test was found to be 0.80 based on Kuder-Richardson formula 20(K-R 20). After this the item analysis of the original knowledge test was done. Three questions were deleted from the test because of high index of difficulty (two questions) and item discrimination of only 0.20.The item analysis for the revised version of the test was done and the reliability of the test was found to be 0.81 using the Kuder-Richardson formula 20 (K-R 20) formula.
