Turkish Adaptation of Eating Expectancy Inventory: Validity and Reliability Study
Project no. 961 · Status: Kapanmış · 2017
Summary
Understanding the cognitive, social and emotional motivations that underlie eating behavior is important for effectively recognition of specific eating problems and to apply appropriate intervention approaches. In this study, it is aimed to adapt the Eating Expectations Inventory which evaluates the different expectations underlying the eating behavior to Turkish. The psychometric properties of the scale were investigated with participated 329 women (average = 21.41) university students. The participants completed the translated Eating Expectancy Inventory (EEI), Eating Disorder Examination Questionnaire (EDE-Q), Dutch Eating Behaviour (DEBQ), Three-Factor Eating Questionnaire (TFEQ-R21), Bulimic Investigatory Test, Edinburg (BITE) and Palatable Eating Motives Scale (PEMS). As a result of the confirmatory factor analysis (CFA) conducted to test the construct validity of the Eating Expectancy Inventory, it was found 5-factor structure solution which is consistent with the original factors [?2 (94, N = 329) = 198,71 p <.000, ?2/df = 2.11, GFI =.93, NFI =.94, CFI = .97 RMSEA=.058]. In order to test the criterion-related validity, the correlation coefficients of the subscales of the EEI scale with the Palatable Eating Motives Scale (PEMS) and the other scales evaluating the impaired eating behaviors were examined. Consequently, it was found that all sub-dimensions of the eating expectancy scale were positively related to emotional eating, restricted eating and uncontrolled eating behaviors (p <.001). As a result of the reliability analysis, the internal consistency coefficients for the sub-dimensions of T-EEI were between .75 and .95; Test-retest reliability was found to vary between .63 and .83. In a conclusion it can be said that the Eating Expectancy Inventory was found to be an adequate tool in terms of valid, reliable and psychometric characteristics.
