Content validity:
The development of the final composition of the Weight Literacy Scale involved a two phase study with three rounds of factor analyses Literacy Scale.
Reliability notes:
Kuder Richardson Coefficient = 0.90. KRC was used because scoring mechanism was binary. The Pearson’s correlation coefficient between the final Weight Literacy Scale scores at baseline and at 2-week follow-up among the subset of Phase 2 participants (N = 71) was 0.72 (95% CI: 0.60–0.82).
