Abstract

Objective: the aim of our study was to adapt and validate the Raynaud’s Condition Score (RCS) in patients with Systemic Sclerosis (SSc) who attend a public hospital in Argentina. Materials and Methods: for adaptation, rheumatologists translated to Spanish the original version in English. To assess the construct validity we used: Health Assesment Questionnaire (HAQ), Duruöz´s Hand Index (DHI), spanish validation for Argentina, Raynaud Visual Analogue Scale (VAS) by an expert and Modified Rodnan skin score (mRSS).To assess reproducibility, a subgroup of patients was randomly evaluated with no changes in treatment or clinical condition ten days after the baseline evaluation. Results: A total of 35 patients with SSc were included. The correlation between RCS and Raynaud VAS by an expert was 0.89; RCS and HAQ 0.58; RCS and mRSS 0.61; RCS and DHI 0.57 indicating a very good correlation mainly between the studied Score and the Raynaud VAS and being all statistically significant. The reproducibility was 0.998. Conclusion: The results show that the RCS is a reliable and valid tool for this argentinian population with SSc.

雷诺条件评分在阿根廷的验证

目的:本研究的目的是适应和验证阿根廷公立医院系统性硬化症(SSc)患者的雷诺病情评分(RCS)。材料和方法:为了适应，风湿病学家将英文原文翻译成西班牙语。我们采用健康评估问卷(HAQ)、Duruöz手部指数(DHI)、阿根廷的西班牙语验证、专家的雷诺视觉模拟量表(VAS)和改良罗南皮肤评分(mRSS)来评估结构效度。为了评估可重复性，在基线评估后10天，在治疗或临床状况没有变化的情况下随机评估一组患者。结果:共纳入35例SSc患者。专家评价RCS与雷诺VAS的相关系数为0.89;RCS和HAQ为0.58;RCS和mRSS 0.61;RCS和DHI为0.57，表明主要研究评分与雷诺VAS之间的相关性非常好，且均具有统计学意义。重现性为0.998。结论:RCS是阿根廷SSc人群的一种可靠、有效的检测工具。
