[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(2)(186) = 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.
