[Experiences with the Three-Factor Eating Questionnaire-R21 in young men].

INTRODUCTION

Eating behaviours play a crucial role in the development of obesity.

AIMS

To conduct a psychometric analysis of the Three-Factor Eating Questionnaire-R21 and to investigate the correlates of obesogenic eating behaviours among males.

METHOD

Participants of the cross-sectional questionnaire-based study were male university students (n = 239, mean of age: 20.3 years, SD = 2.78 years).

MEASURES

self-reported body weight and body height, Three-Factor Eating Questionnaire-R21, Trait Anxiety Scale of the State-Trait Anxiety Inventory.

RESULTS

Results of confirmatory factor analysis supported the theoretical model of the Three-Factor Eating Questionnaire-R21 (χ = 366.1, p<0.001, CFI = 0.959, TLI = 0.954, RMSEA = 0.064). Internal consistency of the scales was adequate (Cronbach's α: 0.79-0.88). Body Mass Index and trait anxiety showed significant, positive associations with eating behaviours, such as uncontrolled eating, cognitive restraint, and emotional eating.

CONCLUSIONS

Results support the construct validity and reliability of the Three-Factor Eating Questionnaire-R21 among males and highlight the importance of taking psychological factors into account in the prevention of obesity. Orv Hetil. 2017; 158(37): 1469-1477.
