Scoring categories:
Scores ≤28 correct may be interpreted as “likelihood of poor nutrition literacy”; Scores of 29–38 correct may be interpreted as “possibility of poor nutrition literacy”; Scores ≥39 may be interpreted as “possibility of good nutrition literacy.”
Reliability: Test-retest correlation:
0.88
Modern Approach for Tool Development:
Yes
About the Validation of this Measure
Country where validated:
United States of America
Content validity:
The development of the tool included an expert panel in Nutrition education and 1 Psychometrician who revised the NLit looking improve the clarity of the format and content for the target patient population.
Criterion validity:
NLit is demonstrated by the strong relationship found between nutrition literacy scores and diet quality scores (HEI-2010). The mean HEI-2010 scores of this sample fell between the 75th and 90th percentiles of scores in the 2003–2004 NHANES nationally representative sample used to validate HEI-20103, indicating better reported diet quality than would be predicted for a general sample of US adults (Gibbs et al., 2017).
Reliability notes:
