Structure validity of the Three-Factor Eating Questionnaire-R18 in Greek population

The aim of the present study was to examine the factor structure of the TFEQ-R18. The project was conducted in Greek population; thus, the questionnaire was translated in Greek language. 495 males and females aged between 12-45 years old participated in the present study. There were used a series of CFA techniques for structure analysis. Confirmatory and exploratory analyses were conducted. Several criteria were used to test the hypotheses factor structures of the AIMS. The results of CFA’s showed that the R-18 item instrument had adequate psychometric properties for measuring three dimensions of eating behavior of the Greek population However these results evealed that an R-16 item instrument was better adapted to the Greek population. The present study provided encouraging preliminary evidence supporting selected psychometric properties of the TFEQ-R18. This instrument seems to be a valid measure of the tendencies of cognitive restraint, uncontrolled eating and emotional eating of Greek population.
