Abstract

To analyze the factor structure and psychometric properties of the TFEQ
in a morbid obese Spanish sample of bariatric surgery
candidates.Multi-trait/ multi-item analyses and alpha coefficients were
conducted to test the convergent /discriminant validity and the internal
consistency reliability. Principal components analyses (varimax) were
used to explore the factor structure. Sub-group factor analyses by
gender, age and body mass index (BMI) were conducted to identify
unstable items.The internal structure of the original TFEQ factors was
unsatisfactory, especially the Disinhibition Scale. Most Disinhibition
and Hunger items were grouped on one factor labeled
“Dysregulation Eating”. Cognitive Restraint was
split into two factors. The first one, related to the behavioral
component of Restraint, labeled “Restrained
Behaviour” and the second one related to weight and eating
concerns called “Predisposition to Restraint”.The
original factor structure of the TFEQ was not replicated. A revised
23-item instrument, representing the three new derived factors is
offered as a valid screening instrument for severely obese patients.
