  • Abstract 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 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 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 3,237 participants (mean age; 42.5±9.3 years; body mass index; 28.9±4.9 kg/m2) were included. Baseline MID scores ranged from 1 to 5 in the health-related quality of life (HRQL) scales and 3 to 6 in the appearance scales. The estimated MID scores from baseline to 3 years follow-up ranged from 4 to 5 in HRQL and from 4 to 8 in 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 use to interpret patients’ BODY-Q scores, evaluate treatment effects of different BCS procedures, and for calculating sample size for future studies.
