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.

Selection of a psychometric approach depends on many factors. Researchers should justify their evaluation method and consider the intended audience. If the instrument is being developed for descriptive purposes and on a restricted budget, a cursory examination of the CTT-based psychometric properties may be all that is possible. In a high-stakes situation, such as the development of a patient-reported outcome instrument for consideration in pharmaceutical labeling, however, a thorough psychometric evaluation including IRT or RMT should be considered, with final item-level decisions made on the basis of both quantitative and qualitative results.
