Validation of the Spanish version of the Food Overeating Questionnaire (OQ) in a sample of Mexican women

Abstract

The goals of this study were to validate the structure of 11 factors of the Overeating Questionnaire, to determine its second-order factors and the relevance of a total score, to check its internal consistency, to describe its distribution, and to compare mean differences between women with normal weight and overweight/ obesity. Information from a sample of 217 women was collected, 50% had normal weight and 50% overweight/ obesity. We suggest reducing the questionnaire to 64 items and nine factors correlated with a good fit in some indexes and internal consistency of .65 to .87. We propose a risk index with normal distribution.
