The purpose of this study was to develop a valid and reliable disease-specific quality-of-life measurement tool for patients with rotator cuff disease.
Design: Health-related quality-of-life measurement tool development.
Methodology for the development and evaluation of the tool included the following: 1) identification of a specific patient population, 2) generation of potential items, 3) item reduction, 4) pretesting the prototype instrument, 5) determination of reliability, and 6) validation.
This measurement tool can be used as the primary outcome in clinical trials evaluating treatments in this patient population, although its features are equally attractive for monitoring patients' progress in clinical practice.
