Only loadings > 0.4 are presented. Three factors with 17 (Factor 1), 13 (Factor 2), and 6 (Factor 3) items respectively were generated. Factor 1 was labeled general flexibility (EDFLIX-GF), Factor 2 was labeled food and exercise flexibility (EDFLIX-FoEx), and Factor 3 was labeled weight and shape flexibility (EDFLIX-WeSh). r = reversed items. Items 1–36 are English translations of the original, Norwegian EDFLIX version, and as such, the English version requires validation.
