ABSTRACT

Objective To develop and evaluate the Quality of Life Instruments for Chronic Diseases -Osteoarthritis ( QLICD-OA). Methods The QLICD-OA was evaluated by testing 140 in-patients with Osteoarthritis. The statistical methods used included correlation analysis, factor analysis, paired t test and Generalizability coefficient. Results The rest-retest reliability γ of QLICD-OA was 0.91, Cronbach’s α for overall scale was 0.98 and Generalizability coefficient was 0.94. Correlation and factor analysis demonstrated good construct validity. After treatment, statistically significant scores were found in the tested group for Specific module and total instrument. Conclusions The QLICD-OA has good validity, reliability and responsiveness. The QLICD-OA may serve as the QOL measurement scale for patients with Osteoarthritis in China.
