Assessing the Validity and Reliability of a Questionnaire on Dietary Fibre-related Knowledge in a Turkish Student Population
Deniz, Melike S. & Alsaffar, Ayten A.
Abstract
This study aimed to validate a questionnaire on dietary fibre (DF)-related knowledge in a Turkish student
population. Participants (n=360) were either undergraduate students who have taken a nutrition course
for 14 weeks (n=174) or those in another group who have not taken such a nutrition course (n=186). Testretest
reliability, internal reliability, and construct validity of the questionnaire were determined. Overall
internal reliability (Cronbach’s alpha=0.90) and test-retest reliability (0.90) were high. Significant differences
(p<0.001) between the scores of the two groups of students indicated that the questionnaire had
satisfactory construct validity. It was found that one-fifth of the students were unsure of the correct answer
for any item, and 52.5% of them were not aware that DF had to be consumed on a daily basis. Only 36.4
to 44.2% of the students were able to correctly identify the food sources of DF.
