To assess the validity and reliability of the Kuwait Adult Nutrition Knowledge Questionnaire (KANKQ) in adult students as an initial step to validation in the general adult population.Methods
Participants (n = 253; aged ≥21 years) were categorized based on academic background and designated into groups known to differ in nutrition knowledge. Participants completed the questionnaire twice. Independent-samples t test, Pearson correlation coefficients, and Cronbach α were used to assess reliability and validity (P < .05).Results
Participants with health-related (n = 144) and nutrition-training backgrounds (n = 58) scored significantly higher than did those without them (n = 109 and 178, respectively; P < .001), indicating good construct validity of the KANKQ. Test-retest reliability (r = .67; P < .001) and internal consistency (α = .81) of the questionnaire were moderate to high.Conclusions and Implications
Further testing of the KANKQ in workplaces and public areas is required for validation in the general adult population. Applicability to neighboring countries of similar background is warranted.
