Abstract

Intuitive Eating is defined as "the dynamic process-integrating attunement of mind, body, and food". The purpose of this study was, therefore, adapt the IES-2 to the Turkish language and reliability and validity of IES-2 among Turkish populations. We also examined the instrument's internal consistency and test-retest reliability and analysed the relationships between the IES-2 and several variables so as to evaluate the convergent and discriminant validity. Three hundred seventy-seven undergraduate and postgraduate women and men between the ages of 19-31 years (mean 22.3, SD = 3.53) attending two large private universities in Istanbul, Turkey. The best solution from the principal factors analysis of the 23 items of the IES-2 revealed four factors corresponding to the four subscales (F1: Eating for physical rather than emotional reasons; F2: Unconditional permission to eat; F3: Reliance on hunger and satiety cues; F4: Body-food choice congruence), as reported by the authors of the questionnaire. Bartlett's test of sphericity gave X2 = 9043.49 (p < 0.001), while the Kaiser-Meyer-Olkin index was 0.87 (KMO were 0.89 for women and 0.83 for men). The test-retest reliability of the IES-2 was 0.88 for the IES-2 total score. The IES-2 had a = 0.82. These findings support the notion that intuitive eating is a viable concept for university students and the IES can be used to examine adaptive eating behaviors in this population.
