Reliability, validity and responsiveness of the Chinese version of the Rotator Cuff Quality of Life Index (RC-QOL) in patients with rotator cuff disorders.

ABSTRACT:

Background

The Rotator Cuff Quality of Life Index (RC-QOL) is a scale designed to evaluate the impact of rotator cuff (RC) disorders on the general quality of life of patients. Our study aims to adapt the RC-QOL into Chinese and to assess its reliability, validity and responsiveness in Chinese patients with RC disorders.

Methods

First, we developed the Chinese version of RC-QOL (C-RC-QOL) through a five-step procedure. Next, the recruited patients gave three rounds of responses to the C-RC-QOL, Medical Outcomes Study Short Form 36 (SF-36) and Oxford Shoulder Score scales (OSS). Then, we calculated the Cronbach's alpha, standard error of measurement (SEM), minimally detectable change (MDC), intra-class correlation coefficient (ICC), Pearson's correlation coefficient (r), effe
