Adaptation and validation of the Portuguese version of the regulation of eating behavior scale (REBSp)

The aim of present study was two-fold: i) to translate and adapt the Regulation Eating Behavior Scale Portuguese (REBSp), ii) analyze its psychometrics properties (factorial validity with gender invariance analyses, reliability construct validity). sample composed by 471 participants (68.4% females) a mean age 30.5 years (SD = 11.2). Structural equation modeling used verify psychometric scale using SPSS v. 23.0 AMOS 24.0 software. analysis showed that 24-item presented good fit, achieving convergent validity. Some issues arose discriminant within autonomous controlled regulations, discussed in light simplex pattern expected self-determination theory literature. Additionally, concurrent evidence measurement invariance. Latent between genders women higher means for intrinsic motivation integrated regulation when compared men. In conclusion, analyses suggest version REBS can be safely assess eating both genders.
