N2 - Background: The BODY-Q is a widely used patient-reported outcome measure for comprehensive assessment of treatment outcomes specific to patients undergoing body contouring surgery (BCS). However, for the BODY-Q to be meaningfully interpreted and used in clinical practice, minimal important difference (MID) scores are needed. A MID is defined as the smallest change in outcome measure score that patients perceive as important. Objectives: The aim of this study was to determine BODY-Q MID estimates for patients undergoing BCS to enhance the interpretability of the BODY-Q. Methods: Data from an international, prospective cohort from Denmark, Finland, Germany, Italy, the Netherlands, and Poland were included. Two distribution-based methods were used to estimate MID: 0.2 standard deviations of mean baseline scores and the mean standardized response change of BODY-Q scores from baseline to 3 years postoperatively. Results: A total of 12,554 assessments from 3237 participants (mean age 42.5 ± 9.3 years; BMI 28.9 ± 4.9 kg/m2) were included. Baseline MID scores ranged from 1 to 5 on the health-related quality of life (HRQL) scales and 3 to 6 on the appearance scales. The estimated MID scores from baseline to 3-year follow-up ranged from 4 to 5 for HRQL and from 4 to 8 on the appearance scales. Conclusions: The BODY-Q MID estimates from before BCS to 3 years postoperatively ranged from 4 to 8 and are recommended for interpretation of patients’ BODY-Q scores, evaluation of treatment effects of different BCS procedures, and calculation of sample size for future studies.
