A validated assessment of pruritus intensity is an important but still difficult clinical problem due to a subjective nature of this sensation.
The aim of this study was the creation and validation of new itch severity questionnaire assessing pruritus intensity.
A total of 148 patients with pruritic dermatoses were asked to assess pruritus intensity using 12-Item Pruritus Severity Score (12-PSS) and Visual Analogue Scale (VAS). Patients were also asked to complete the Dermatology Life Quality Index (DLQI) and Hospitality Anxiety and Depression Scale (HADS). Test-retest comparison of 12-PSS was conducted in 102 subjects who completed the itch questionnaire twice with the 3- to 5-day interval.
We have created the 12-PSS assessing pruritus intensity (two questions), pruritus extent (one question) and duration (one question), influence of pruritus on concentration and patient psyche (four questions), and scratching as a response to pruritus stimuli (four questions). A maximum scoring was 22 points. The results showed strong consistency (Cronbach coefficient 0.81). A significant correlation was observed with VAS ( = 0.58, < 0.001) and quality of life level according to DLQI ( = 0.53, < 0.001). Test-retest comparison in 102 subjects revealed a satisfactory reproducibility of achieved results (ICC = 0,72).
The newly developed pruritus severity questionnaire may be used in daily clinical practice in the future.
由于瘙痒感的主观性，对其强度进行有效的评估是一个重要但仍具有挑战性的临床问题。
本研究旨在创建和验证一种新的瘙痒严重程度问卷，以评估瘙痒强度。
共招募 148 例瘙痒性皮肤病患者，使用 12 项瘙痒严重程度评分（12-PSS）和视觉模拟评分（VAS）评估瘙痒强度。患者还需完成皮肤病生活质量指数（DLQI）和医院焦虑抑郁量表（HADS）。在 102 例患者中进行了 12-PSS 的测试-重测比较，这些患者在 3-5 天的间隔内两次完成了瘙痒问卷。
我们创建了 12-PSS，用于评估瘙痒强度（两个问题）、瘙痒范围（一个问题）和持续时间（一个问题）、瘙痒对注意力和患者心理的影响（四个问题）以及搔抓作为对瘙痒刺激的反应（四个问题）。最高得分为 22 分。结果显示具有很强的一致性（Cronbach 系数为 0.81）。与 VAS（ = 0.58，<0.001）和根据 DLQI 评估的生活质量水平（ = 0.53，<0.001）呈显著相关。在 102 例患者中进行的测试-重测比较显示，获得的结果具有良好的可重复性（ICC = 0.72）。
新开发的瘙痒严重程度问卷将来可用于日常临床实践。
