El objetivo de este estudio fue examinar la validez de constructo del Cuestionario de Tres Factores de Alimentación (TFEQ) revisado-18, un instrumento diseñado para medir: Ingesta Incontrolada (II), Ingesta Emocional (IE), y Restricción Cognitiva (RC), en mexicanos adultos de diferentes pesos. Participaron 342 hombres y mujeres, con un rango de edad 19-79 años (M 40). A los participantes se les midió peso y estatura y posteriormente se les envió TFEQ por correo electrónico. La estructura del TFEQ se examinó con el análisis factorial exploratorio y confirmatorio. Se corroboró la estructura original de tres factores, con nueve reactivos que cargaron alto en II, tres en IE y cuatro de los seis originales en RC. Se excluyeron dos ítems debido a las bajas correlaciones reactivo–puntaje total. Los niveles más altos de RC se asociaron con un IMC más alto (r .13, p <.05), no se encontraron relaciones entre II o IE y el peso corporal. Nuestros hallazgos sugieren que el TFEQ abreviado (16 ítems) es una medida psicométricamente válida y puede usarse para evaluar las tendencias de II, IE, y RC en la población de adultos mexicanos con diferentes pesos.
The objective of this study was to examine the construct validity of the Three Factor Eating Questionnaire (TFEQ) Revised-18, an instrument designed to measure: Uncontrolled Eating, Emotional Eating and Cognitive Restraint, in a sample of Mexican adults of different weights. 342 man and women, with age range 19-79 years old (M=40), were recruited. TFEQ was emailed to the participants who earlier had their weight and height measured. Exploratory and confirmatory factor analysis was applied to examine TFEQ structure. The original three factor structure was corroborated, with nine items loading high on Uncontrolled Eating factor, three on Emotional Eating and four out of the original six on Cognitive Restraint. Two items were excluded due to low item-total correlations. Higher levels of Cognitive Restraint were associated with higher BMI (r=.13, p < .05), we found no connection between Uncontrolled Eating or Emotional Eating and body weight. Our findings suggest that the abbreviated TFEQ (16 items), is a psychometrically valid measure, and can be used to evaluate the tendencies of Cognitive Restraint, Uncontrolled Eating and Emotional Eating in the population of Mexican adults with different body weights.
