No scoring systems to evaluate overall hair loss activity in alopecia areata (AA) have been established.
We sought to develop a measurement tool (Alopecia Areata Progression Index, AAPI) for the evaluation of overall hair loss activity in AA patients with pigmented hair.
The scalp surface area was divided into 4 quadrants. In each quadrant, hair loss activity was scored on the basis of the percentage of alopecic area, clinical findings associated with hair loss. The AAPI was measured in 17 patients with different severities of AA.
Interobserver and intraobserver reliabilities were assessed by 4 investigators. A significant correlation of the total AAPI was found among the 4 investigators. In addition, intraobserver reliability was excellent, and interobserver reliability was statistically reliable.
The AAPI seems to represent a system capable of truly quantifying overall hair loss activity in AA patients with different severity, demonstrating trustworthy interobserver and intraobserver reliability.
目前尚未建立评估斑秃（AA）患者整体脱发活动度的评分系统。
我们试图开发一种测量工具（斑秃进展指数，AAPI），用于评估有色素毛发的AA患者的整体脱发活动度。
将头皮表面积分为4个象限。在每个象限中，根据脱发区域的百分比、与脱发相关的临床发现对脱发活动度进行评分。对17例不同严重程度的AA患者测量了AAPI。
4名研究者评估了观察者间和观察者内的可靠性。4名研究者之间发现总AAPI存在显著相关性。此外，观察者内可靠性极佳，观察者间可靠性具有统计学意义。
AAPI似乎是一个能够真正量化不同严重程度AA患者整体脱发活动度的系统，具有可靠的观察者间和观察者内可靠性。
