本研究旨在检验雷诺现象（RP）患者诊断性热血管试验（TVT）的可靠性和有效性。TVT检查了手指血压对联合冷却和闭塞的反应，并作为雷诺氏治疗研究的一部分开发，雷诺氏治疗研究是一项比较生物反馈和药物治疗效果的多中心临床试验。计算机化系统允许在不同的地理位置进行有效、准确和统一的测试。报告了199例RP患者和52例健康对照的比较。TVT的敏感性为79%，特异性为88%。重测信度是可以接受的（r=. 80）。此外，心理挑战未能改善RP患者和对照组之间的歧视。TVT分离RP患者和对照组以及或优于现有的测试，并增强了操作的方便性。（PsycInfo数据库记录（c）2022阿帕，保留所有权利）
This study tested the reliability and validity of a diagnostic thermal vascular test (TVT) for patients with Raynaud's Phenomenon (RP). The TVT examined digital blood pressure responses to combined cooling and occlusion and was developed as part of the Raynaud's Treatment Study, a multicenter clinical trial comparing the efficacy of biofeedback and pharmacological treatment. A computerized system permitted efficient, accurate, and uniform testing at different geographical sites. A comparison of 199 patients with RP and 52 healthy controls is reported. The TVT showed a sensitivity of 79% and a specificity of 88%. Test–retest reliability was acceptable (r=. 80). Addition of a psychological challenge failed to improve the discrimination between patients with RP and controls. The TVT separated patients with RP and controls as well as or better than existing tests and did so with enhanced ease of operation.(PsycInfo Database Record (c) 2022 APA, all rights reserved)
