title: Development and validation of a new questionnaire measuring eating disordered behaviours post bariatric surgery.
abstract: Contextualization of post-surgery circumstances in terms of key behaviours and emotions related to eating is crucial for reliable screening. Disordered eating post surgery is characterized by frequent snacking and a sense of loss of control over food intake. The purpose of this study was to evaluate the psychometric properties of a short self-report questionnaire entitled Disordered Eating after Bariatric Surgery (DEBS). Results indicate that the DEBS possesses satisfactory psychometric properties in terms of reliability, validity, internal consistency and test-retest reliability. The DEBS may facilitate both systematic clinical evaluation and future research within the area of bariatric surgery.
