Validity varied extensively and there was a widespread lack of information regarding measurement of change over time and patient burden .
According to the evaluation criteria , there was adequate support for two tools .
The present study aims to identify the range of  eating behavior self- assessment tools reported in the adult bariatric surgery literature and evaluate the measurement properties of these tools using pre-established criteria .
Psychometric properties and factor structure of the Three-Factor Eating Questionnaire (TFEQ) in obese men and women. Results from the Swedish Obese Subjects (SOS) study
OBJECTIVE : To evaluate the construct validity of the Three-Factor Eating Question naire ( TFEQ ) in obese men and women . SUBJECTS : A total of 4377 middle-aged , obese subjects in the Swedish Obese Subjects ( SOS ) study . METHODS : The total sample was r and omly split into two data subsets and psychometric testing was performed separately in each sample . Multitrait/multi-item analysis was conducted to test scaling assumptions and factor analysis was used to test the factor structure . Measures of mental well-being ( MACL , HAD ) were used for testing criterion-based validity . RESULTS : The Cognitive Restraint factor was consistently reproduced and scaling analysis demonstrated strong item-scale discriminant validity , while the item-scale convergent validity was unsatisfactory . The internal structure of the Disinhibition scale was weak . Most Disinhibition and Hunger items grouped in one global factor labeled Uncontrolled Eating . A third cluster containing items on Emotional Eating was also identified . The obtained three-factor structure was cross-vali date d and replicated across subgroups by gender , age and BMI . CONCLUSION : The original TFEQ factor structure was not replicated . A short , revised 18-item instrument was constructed , representing the derived factors of Cognitive Restraint , Uncontrolled Eating and Emotional Eating . The most efficient items were used to boost both the convergent and discriminant validity of the scales
