This study examined the factor structure and psychometric properties of the Spanish version of theWeight Efficacy Life-Style Questionnaire (WEL), an instrument developed to measure self-efficacy in relation to food intake. A total of 292 Spanish persons participated, from three groups: clinical group, overweight group, and normal-weight group. The findings showed evidence of three situational factors (Negative Emotions, Social Pressure, and Physical Discomfort). The confirmatory factor analysis corroborated the three-factor model on an independent sample (N = 345). The results show a high degree of internal consistency of the scores of WEL. Significant correlations were found between the WEL scores and other variables that were hypothesized would be related to them. Significant differences on self-efficacy scores were found between some of the groups. The scores of WEL also significantly correlated with the Eating Self-Efficacy Scale scores. Finally, results are discussed and future research directions are suggested.
