OBJECTIVES: There is a lack of a psychometrically robust bariatric-specific health related quality of life (HRQOL) tool. A mono-centric prospective study was conducted to develop and validate a new bariatric specific 81-item self report HRQOL instrument called the Bariatric and Obesity Surgery Survey (BOSS). METHODS: Data were collected from 236 participants: 83 patients who were under consideration for bariatric surgery, 68 patients who already have had a bariatric procedure and 85 volunteers. Participants were also required to complete the Short Form Health survey (SF-36), Hospital Anxiety and Depression (HADS) scale, Moorehead- Ardelt Quality of life Questionnaire (M-A QoLQ II), and a demographic data sheet. Two weeks following the completion of these 5 questionnaires, participants were asked to complete BOSS once more along with a feedback sheet. RESULTS: Exploratory factor analysis revealed a multidimensional instrument consisting of 42 items distributed over 6 domains that address various HRQOL aspects and dimensions pertinent to bariatric surgery, and relevant to morbidly obese patients. Further psychometric analysis showed that BOSS has adequate internal consistency reliability (Cronbach alpha = 0.970), test re-test reliability (ICC = 0.926), construct validity, criterion validity, face validity and acceptability. CONCLUSIONS: BOSS is a valid and reliable multidimensional instrument that provides a clinically useful and relevant measure to assess HRQoL in patients undergoing bariatric surgery.
