Nutrition Literacy Assessment Instrument in Breast Cancer

CFI≥0.90 indicates acceptable model fit

RMSEA≤0.06 indicates acceptable model fit

Entire reliability is the reliability of the entire domain. 0.81–1.0 is substantial reliability

Test-retest reliability evaluates the consistency of measurement results between two testing occasions.

We classified reliability as follows: slight to moderate reliability,

fair to substantial reliability,

substantial reliability according to Shrout's guidelines [19]
