Validation of a general nutrition knowledge questionnaire in a Turkish student sample
PubMed ID: 22281193 ; Objective To validate the general nutrition knowledge questionnaire developed by Parmenter and Wardle (1999) in a Turkish student sample. Design The original questionnaire of Parmenter and Wardle (1999) was modified and translated into Turkish. The modified questionnaire was administered to second year undergraduate students. Some students completed the questionnaire twice for the measurement of test-retest reliability. Statistical analysis was performed on the responses to measure the internal reliability, test-retest reliability and construct validity. Setting Students completed the questionnaire under supervision. The questionnaire was completed at the end of lectures. Retest was carried out two weeks after first administration of the test. Subjects A total of 195 undergraduate students studying either nutrition and dietetics (n 90) or engineering (n 105) participated in the study. Of these, 125 students completed the questionnaire on two occasions. Results Overall internal reliability (Cronbach's ? = 0·89) and test-retest reliability (0·86) were high. Significant differences between the scores of the two groups of students indicated that the questionnaire had satisfactory construct validity. Conclusions The modified version of the general nutrition knowledge questionnaire can be used as a tool to examine the nutrition knowledge of adults in Turkey. In the next stage of the study, some adjustments need to be made to the items that led to low reliability values so that these items will be more applicable to the eating habits and patterns of Turkish people. © The Authors 2012.
