Abstract

Objectives: The Psoriasis Epidemiology Screening Tool (PEST) is a simple and useful questionnaire designed to screen arthritis in patients with psoriasis. This study aims to evaluate the validity and reliability of the PEST questionnaire in Turkish patients with psoriasis.

Patients and methods: Between August 2019 and September 2019, a total of 158 adult patients with psoriasis (61 males, 68 females; mean age: 43.1±13.3 years; range, 29.8 to 56.4 years) who were not previously diagnosed with PsA were included. The testing procedure for translation and cultural adaptation was carried out according to the following steps: preparation, forward translation, reconciliation, back-translation/back-translation review, harmonization, finalization, and proofreading. Patients' demographic parameters, comorbidities, PEST, and Toronto Psoriatic Arthritis Screen (ToPAS 2) results were recorded. The patients were, then, assessed by a rheumatologist who was blinded to their PEST scores. The diagnosis of PsA was made according to the Classification criteria for Psoriatic Arthritis (CASPAR). The receiver operating characteristic (ROC) was assessed to obtain the sensitivity and specificity of the PEST questionnaire.

Results: Of the patients, 42 had PsA, while 87 did not. Each parameter of PEST showed a low-high internal consistency ranging from 0.366 to 0.781. When the Question 3 was excluded, Cronbach alpha value increased to 0.866. The Cronbach alpha value of the whole scale was 0.829. The test-retest reliability of the Turkish version of PEST was determined as 0.86 for the total score (ICC=0.866 95% CI: 0.601-0.955; p<0.0001). There was a strong positive correlation between PEST and ToPAS 2 (r=0.763; p<0.001) and a moderate positive correlation between PEST and CASPAR (r=0.455; p<0.001). A cut-off value of ≥3 yielded a sensitivity of 93% and a specificity of 89% for the diagnosis of PsA with the highest Youden's index. The PEST scale was found to have a higher sensitivity, but lower specificity in the head-to-head comparison with ToPAS 2.

Conclusion: The Turkish version of PEST is a reliable and valid tool for screening PsA in Turkish patients with psoriasis.

土耳其版牛皮癣流行病学筛查工具检测牛皮癣患者银屑病关节炎的效度和信度

目的:银屑病流行病学筛查工具(PEST)是一种简单实用的调查问卷，旨在筛查银屑病患者的关节炎。本研究旨在评估PEST问卷在土耳其银屑病患者中的效度和信度。患者与方法:2019年8月至2019年9月，共158例成年牛皮癣患者(男性61例，女性68例;平均年龄:43.1±13.3岁;年龄范围29.8 - 56.4岁)，既往未诊断为PsA的患者也包括在内。翻译和文化适应性测试程序按照以下步骤进行:准备、正译、核对、反译/反译审查、协调、定稿和校对。记录患者的人口统计学参数、合并症、PEST和多伦多银屑病关节炎筛查(topas2)结果。然后，由一名风湿病学家对患者进行评估，该专家对他们的PEST评分不知情。根据银屑病关节炎分类标准(CASPAR)诊断PsA。评估受试者工作特征(ROC)以获得PEST问卷的敏感性和特异性。结果:42例患者有PsA, 87例患者无PsA。PEST各参数的内部一致性为低-高，范围为0.366 ~ 0.781。排除问题3后，Cronbach alpha值增加到0.866。整个量表的Cronbach alpha值为0.829。土耳其版PEST总分的重测信度为0.86 (ICC=0.866 95% CI: 0.601-0.955;结论:土耳其版PEST是筛查土耳其银屑病患者PsA的可靠有效工具。
