Abstract

The aims of this study were to analyze the psychometric properties of the Spanish version of the Three-Factor Eating Questionnaire-R18 (TFEQ-SP), as well as determine its validity by evaluating the relationship of the TFEQ-SP with different parameters related to body mass index, weight perception, perception of physical fitness, self-esteem, and food intake, as well as with weight control-related variables. A total of 281 participants (aged 18.38 ± 6.31) were studied. The factor analysis yielded three factors: cognitive restraint (CR), uncontrolled eating (UE), and emotional eating (EE). The internal consistency of the TFEQ-SP was determined by means of Cronbach’s α coefficient, with values ranging between 0.75 and 0.87. Higher scores on CR were found in women (p < 0.5), overweight/obese participants (p < 0.001), participants with lower self-esteem (p < 0.05), participants who overestimated their weight (p < 0.001), participants who weighed themselves frequently (p < 0.001) and those who were about to go on a diet (p < 0.001). Higher EE scores were found in participants with lower self-esteem scores (p < 0.05), among participants with a poorer perception of their physical fitness (p < 0.01) and when participants were about to diet (p < 0.05). Higher scores on UE were observed in case of poorer perception of physical fitness (p < 0.05). The validation study of the TFEQ-SP meets the requirements for measuring the three different facets of eating behavior: CR, UE, and EE.

Highlights

Interactions between eating behavior and health are a field of study absolutely necessary to improve prevention programs, as well as treatments, regarding eating disorders and obesity among other disturbances [1]
With respect to the criterion validity, this study based on Three-Factor Eating Questionnaire (TFEQ) includes different variables, such as anthropometrical, psychological, related to weight and body shape perception, related to physical activity and self-reported physical fitness and those related to diet and food intake
Our results show that students with a higher Body Mass Index (BMI) refer more cognitive restraint (CR) but this is not the case for those with lower

Summary

Introduction

Interactions between eating behavior and health are a field of study absolutely necessary to improve prevention programs, as well as treatments, regarding eating disorders and obesity among other disturbances [1]. In the study of eating behaviors, the concept of dietary restraint is relevant, highlighting the regulation of food intake in order to control weight and body shape. Other eating behaviors have been described such as loss of control over intake and overeating as consequence of emotional distress [3]. Behaviour Questionnaire) have been designed to measure these different eating behaviors, especially dietary restraint, trying to find the most appropriate one [4,5,6]. Apart from the design of instruments, it is necessary to study the validity of them across different populations (obese and normal weight persons, clinical and non-clinical samples, groups of different sex and age, etc.) [2]
