Self-efficacy in eating management.: The Spanish version of the Eating Self-Efficacy Scale.

This study analyses the factorial structure and psychometric properties of the Eating Self Efficacy Scale (ESES; Glynn y Ruderman, 1986), an instrument developed to measure self-efficacy in relation to food intake. Two hundred and ninety-eight Spanish Subjects participated, distributed in two groups: normal-weight group (n= 193), and overweight and obese group (n= 105). The findings reveal evidence of two Situational factors (Negative Affect and Soccially Acceptable Circumstances). The confirmatory factor analysis corroborated the two-factor model oil an independent sample (N= 345). The results show a high level of internal consistency. significant correlations were found between the ESES scores and other variables that we hypothesised would be related to them.
