UNASSIGNED: Consecutive Algerian patients who fulfilled the American College of Rheumatology/European League Against Rheumatism criteria for systemic sclerosis were included. In addition to disease characteristics, global disability and hand disability were assessed using the Arabic Health Assessment Questionnaire and the Arab Hand Function Index, respectively. Construct validity was assessed by convergent and divergent validity (Spearman\'s rank correlation coefficient) and factor analysis. The scale reliability was assessed using the Cronbach\'s alpha.
UNASSIGNED: We evaluated 100 systemic sclerosis patients (83 females) of mean ± standard deviation age 46.7 ± 12.3 years, including 59 limited cutaneous systemic sclerosis and 41 diffuse cutaneous systemic sclerosis. Raynaud\'s phenomenon was detected in 99 patients and digital ulcers in 25. Gastrointestinal tract involvement and interstitial lung disease were detected in 86/100 (86%) and 46/72 (63.9%) patients, respectively. Anti-topoisomerase I and anti-centromere antibodies were detected in 33/76 (43.4%) and 23/76 (30.3%) patients, respectively. The Arab Hand Function Index had a good construct validity with a total score explaining 61% of the variance of the Arabic Health Assessment Questionnaire which also had a good construct validity. Factor analysis of the Arab Hand Function Index and the Arabic Health Assessment Questionnaire items extracted two factors explaining 64% of the variance for the Arab Hand Function Index and one factor explaining 55% of the variance for the Arabic Health Assessment Questionnaire. The Arab Hand Function Index and the Arabic Health Assessment Questionnaire were reliable questionnaires with a Cronbach\'s alpha >0.8.
UNASSIGNED: In Algerian patients with systemic sclerosis, Arab Hand Function Index and Arabic Health Assessment Questionnaire have a good construct validity and reliability.
■符合美国风湿病学会/欧洲抗风湿病联盟系统性硬化症标准的连续阿尔及利亚患者纳入研究。除了疾病的特点,使用阿拉伯健康评估问卷和阿拉伯手功能指数评估全球残疾和手残疾,分别。通过收敛效度和发散效度(Spearman的等级相关系数)和因子分析评估结构效度。量表的可靠性是使用Cronbach的α进行评估的。
■我们评估了100名系统性硬化症患者(83名女性),平均年龄为46.7±12.3岁,包括59例局限性皮肤系统性硬化症和41例弥漫性皮肤系统性硬化症。在99例患者中检测到雷诺现象,在25例患者中检测到数字溃疡。在86/100(86%)和46/72(63.9%)患者中检测到胃肠道受累和间质性肺病,分别。在33/76(43.4%)和23/76(30.3%)患者中检测到抗拓扑异构酶I和抗着丝粒抗体,分别。阿拉伯手功能指数具有良好的构造效度,总分可解释阿拉伯健康评估问卷的61%的方差,该量表也具有良好的构造效度。阿拉伯手功能指数和阿拉伯健康评估问卷项目的因素分析提取了两个因素,这些因素解释了阿拉伯手功能指数的方差的64%,而一个因素解释了阿拉伯健康评估问卷的方差的55%。阿拉伯手功能指数和阿拉伯健康评估问卷是可靠的问卷,Cronbach'salpha>0.8。
