ABSTRACT
The present study investigated the psychometric properties of the Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES) in the context of overweight and obesity. The instrument was investigated in a non-probabilistic sample of 177 individuals who were overweight or obese. A confirmatory factor analysis (CFA) was performed in order to provide evidence based on the internal consistency of the SOCRATES-OO scale with three correlated factors and two correlated factors. In addition, the University of Rhode Island Change Assessment (URICA) raw score was used to provide evidence in terms of convergent validity by its correlation with the domains of the best SOCRATES-OO solution. According to CFA, the theoretical solution with two correlated factors provided a better statistical fit. The psychometric evaluation of the 19 items of SOCRATES-OO presented a good fit under the two-factor model and satisfactory internal consistency by Omega of AMREC (Ambivalence + Recognition) 0.924 and Action 0.942.
