Clinical validation of the trait and state versions of the Food Craving Questionnaire.

This is the first study to evaluate the psychometric properties of the Food Craving Questionnaire-Trait (FCQ-T), and Food Craving Questionnaire-State (FCQ-S) measures using a clinically heterogeneous sample of eating disorder patients (N = 177) recruited from seven different outpatient eating disorder treatment centers in Spain. Confirmatory factor analyses (CFAs) corroborated the factor structures of the FCQ-T and FCQ-S. The measures' scores and their factor-derived scale-scores yielded internal consistency reliability indexes that ranged from adequate to excellent. The measures were predictive of eating disorder symptoms. As expected, the FCQ-T was more strongly associated with eating disorder psychopathology than the FCQ-S. The results replicated the psychometric properties of the FCQ-T and FCQ-S in eating disorder populations and could become useful tools in clinical and research settings.
