OBJECTIVE
To determine the interrater and test-retest reliability and validity of the Arthritis Hand Function Test (AHFT) in persons with systemic sclerosis.
METHODS
Interrater reliability of the AHFT was established by two raters independently scoring the performances of 20 women with systemic sclerosis. The same group of subjects was tested again 7-10 days later to determine test-retest reliability. Concurrent validity was established by the subjects' self-reports of their abilities to perform activities of daily living as measured by the Health Assessment Questionnaire and the Arthritis Impact Measurement Scales 2 (AIMS2).
RESULTS
All of the items had excellent interrater intraclass correlation coefficients (ICC = 0.99-1.00). The ICCs for test-retest reliability were in the excellent (ICC = 0.80-0.97) range for most of the items and moderate (ICC = 0.57-0.73) for the others. Most of the items were moderately correlated with items on the AIMS2 (r = 0.45-0.69).
CONCLUSION
The results from this study suggest that the AHFT is a reliable and valid test to measure hand function in persons with systemic sclerosis.
目的
确定关节炎手部功能测试（AHFT）在系统性硬化症患者中的评分者间信度、重测信度及效度。
方法
两名评分者对20名系统性硬化症女性患者的表现进行独立评分，以此确定AHFT的评分者间信度。7至10天后，对同一组受试者再次进行测试，以确定重测信度。通过受试者根据健康评估问卷和关节炎影响测量量表2（AIMS2）对其日常生活活动能力的自我报告来确定同时效度。
结果
所有项目的评分者间组内相关系数均极佳（ICC = 0.99 - 1.00）。大多数项目的重测信度ICC处于极佳范围（ICC = 0.80 - 0.97），其他项目则为中等（ICC = 0.57 - 0.73）。大多数项目与AIMS2上的项目中度相关（r = 0.45 - 0.69）。
结论
本研究结果表明，AHFT是一种可靠且有效的测试，可用于测量系统性硬化症患者的手部功能。
