Content validity: An original list of previously used 27 behavior questions drawn from EFNEP along with other research was used as the starting point and narrowed down to 18 behavior items for the pilot testing for face validity. Consideration was given to colloquial terms, and these were changed as necessary such as 'grocery' used in the US to 'shopping' in Australia. Items selected were to be consistently answered on the same Likert scale of frequency from 'never'(1) to 'always'(5).

Reliability notes: Cronbach's alpha was used to explore internal consistency of each of the defined food literacy behavior factors, calculated to be 0.79, 0.76, and 0.81 for Plan & Manage, Selection, and Preparation.
