Few studies have validated standard measurement instruments for evaluation of chronic pruritus. The Chronic Pruritus Tools Questionnaire PRURITOOLS assembles a set of instruments for the assessment of pruritus, such as the visual analogue scale (horizontal 100-mm line), numerical rating scale (0-10), verbal rating scale, and information on pruritus quality and improvement during therapy. This study, with 40 subjects, analysed PRURITOOLS regarding convergent validity and test-retest reliability (60 min), followed by a feasibility questionnaire. Test-retest reliability for PRURITOOLS items was excellent (intraclass correlation coefficient 0.84-1). Strong to very strong correlations between the pruritus intensity scales indicated convergent validity. The feasibility questionnaire showed an overall acceptance of PRURITOOLS, and the majority of subjects (82.5%) considered it an appropriate questionnaire to measure pruritus. In conclusion, PRURITOOLS offers validated tools for rapid pruritus assessment in routine care or endpoints of clinical trials.
很少有研究验证过用于评估慢性瘙痒的标准测量工具。慢性瘙痒工具问卷 PRURITOOLS 汇集了一套用于评估瘙痒的工具，例如视觉模拟量表（水平 100 毫米线）、数字评定量表（0-10）、言语评定量表，以及关于瘙痒质量和治疗期间改善的信息。这项有 40 名受试者参与的研究分析了 PRURITOOLS 的收敛效度和测试-重测信度（60 分钟），随后是一份可行性问卷。PRURITOOLS 项目的测试-重测信度非常好（组内相关系数 0.84-1）。瘙痒强度量表之间的强到非常强的相关性表明了收敛效度。可行性问卷显示了对 PRURITOOLS 的总体接受程度，大多数受试者（82.5%）认为它是一种合适的测量瘙痒的问卷。总之，PRURITOOLS 提供了经过验证的工具，可用于在常规护理或临床试验终点快速评估瘙痒。
