BACKGROUND
The self-assessment psoriasis area severity index (SAPASI) is a patient-administered psoriasis assessment tool for which we present a validated translation from English to Swedish.
METHODS
Validity was evaluated in this single-centre study using the psoriasis area severity index (PASI) as the standard. Test-retest reliability was assessed using repeated SAPASI measurements.
RESULTS
Significant correlations (p < 0.0001) using Spearman's correlation coefficient (r) were found between PASI and SAPASI scores (r = 0.60) for 51 participants (median baseline PASI 4.4, interquartile range [IQR]: 1.8-5.6) and repeated SAPASI measurements (r = 0.70) among 38 participants (median baseline SAPASI 4.0, IQR: 2.5-6.1). Bland-Altman plots showed generally higher SAPASI scores than PASI scores.
CONCLUSION
The translated version of SAPASI is valid and reliable, although patients generally tend to overrate their disease severity compared to PASI. Keeping this limitation in mind, SAPASI has the potential of being implemented as a time- and cost-efficient assessment tool in a Scandinavian context.
背景
自我评估银屑病面积严重指数（SAPASI）是一种患者自评的银屑病评估工具，我们对其进行了从英语到瑞典语的验证性翻译。
方法
本单中心研究采用银屑病面积严重指数（PASI）作为标准来评估其有效性。使用重复的 SAPASI 测量来评估测试-重测信度。
结果
51 名参与者（中位基线 PASI 为 4.4，四分位距 [IQR]：1.8-5.6）的 PASI 和 SAPASI 评分之间存在显著相关性（p < 0.0001），Spearman 相关系数（r）为 0.60，而 38 名参与者（中位基线 SAPASI 为 4.0，IQR：2.5-6.1）的重复 SAPASI 测量之间也存在显著相关性（r = 0.70）。Bland-Altman 图显示 SAPASI 评分普遍高于 PASI 评分。
结论
虽然患者在自我评估疾病严重程度时往往会过高估计，但 SAPASI 的翻译版本具有有效性和可靠性。考虑到这一局限性，SAPASI 有可能在斯堪的纳维亚地区作为一种省时、省钱的评估工具得到实施。
