Alopecia areata (AA) is a non-scarring autoimmune disease characterized by patchy hair loss. The aim of this study was to validate a novel trichoscopic scoring tool, the Severity TRichoscopy Index for Alopecia Areata (STRIAA), for rapid assessment of AA severity.
Anonymized images from 340 patients were scored by two independent raters who analyzed four scalp areas (vertex, occipital, and left and right parietal) for trichoscopic signs: black dots, yellow dots, exclamation mark hairs, broken hairs, and short vellus hairs. Scores (0-3) were assigned according to the number of trichoscopic signs per area, resulting in a total STRIAA score out of 60.
STRIAA showed high interrater reliability (Cronbach's alpha 0.99) and significant correlation with the Severity of Alopecia Tool (SALT) score (p < 0.001). Yellow and black dots were significantly associated with the SALT score.
The STRIAA provides a rapid and comprehensive assessment of AA severity, complementing current assessment tools in clinical practice.
斑秃（AA）是一种非瘢痕性自身免疫性疾病，其特征为斑片状脱发。本研究的目的是验证一种新型的毛发镜评分工具，即斑秃严重程度毛发镜指数（STRIAA），用于快速评估斑秃的严重程度。
由两名独立评估者对340例患者的匿名图像进行评分，他们分析了四个头皮区域（头顶、枕部以及左右顶叶）的毛发镜特征：黑点、黄点、惊叹号样毛发、断发和短小毳毛。根据每个区域毛发镜特征的数量给予评分（0-3分），得出STRIAA总分，最高为60分。
STRIAA显示出较高的评估者间信度（Cronbach's α系数为0.99），并且与斑秃严重程度工具（SALT）评分显著相关（p < 0.001）。黄点和黑点与SALT评分显著相关。
STRIAA为斑秃严重程度提供了快速且全面的评估，在临床实践中对现有评估工具起到了补充作用。
