Background: Measuring patient-reported outcomes has become increasingly important in cosmetic and reconstructive breast surgery. The objective of this study was to develop a new patient-reported outcome measure to assess the unique outcomes of breast surgery patients. Methods: Patient interviews, focus groups, expert panels, and a literature review were used to develop a conceptual framework and a list of questionnaire items. Three procedure-specific questionnaires ( augmentation, reduction, and reconstruction) were developed and cognitive debriefing interviews used to pilot each questionnaire. Revised questionnaires were field tested with 1950 women at five centers in the United States and Canada ( response rate, 72 percent); 491 patients also completed a test-retest questionnaire. Rasch measurement methods were used to construct scales, and traditional psychometric analyses, following currently recommended procedures and criteria, were performed to allow for comparison with existing measures. Results: The conceptual framework included six domains: satisfaction with breasts, overall outcome, and process of care, and psychosocial, physical, and sexual well-being. Independent scales were constructed for these domains. This new patient-reported outcome measure system ( the BREAST-Q) contains three modules ( augmentation, reconstruction, and reduction), each with a preoperative and postoperative version. Each scale fulfilled Rasch and traditional psychometric criteria ( including person separation index 0.76 to 0.95; Cronbach's alpha 0.81 to 0.96; and test-retest reproducibility 0.73 to 0.96). Conclusions: The BREAST-Q can be used to study the impact and effectiveness of breast surgery from the patient's perspective. By quantifying satisfaction and important aspects of health-related quality of life, the BREAST-Q has the potential to support advocacy, quality metrics, and an evidence-based approach to surgical practice.
