摘要

The purpose of this study is to develop an outcome measurement instrument for knee osteoarthritis and demonstrate its ability to evaluate different interventions in the medical care of knee osteoarthritis. Developed out of concerns over health-related quality of life, the instrument assesses dimensions of functional status in patients with knee osteoarthritis. A literature review was first performed, followed by seven questionnaires being submitted to knee osteoarthritis, and then review by an expert and lay panel. A cross-sectional and longitudinal survey design was used. A purposive sample was taken from 111 patients with knee osteoarthritis, who were recruited from outpatient services in a medical center. Principal-axis factor analysis with direct oblimin rotation generated a thirty-five item, 5-factor structure, namely pain, activities of daily living and symptoms, mobility function, emotional function and social participation function, accounting for 52.34% of the total variance. Comparison with the group who had taken glucosamine medication revealed longitudinal changes in the instrument total and five subscale scores (p＜.0l). With respect to criterion-related validity, the “pain” subscale of the instrument was significantly correlated with the pain-visual analog scale (r=.73, p＜.000). In addition, the “activities of daily living and symptoms” subscale of the instrument were significantly correlated with the Index of Severity for Osteoarthritis of the Knee (r=.80, p＜.000). The internal consistency reliability established by Cronbachs alpha ranged from 0.79 to 0.90. In conclusion, the study demonstrates that the outcome measurement instrument for the medical care of knee osteoarthritis developed in this paper is reliable and valid.
