The aim of this study was to develop and validate a Japanese version of the Athens Insomnia Scale (AIS-J).
The AIS-J was created using a back-translation design. A total of 477 outpatients with chronic insomnia and 163 individuals from the general community were recruited. Participants were asked to complete the AIS-J along with two other insomnia scales - Japanese versions of the Pittsburgh Sleep Quality Index and the Insomnia Severity Index.
The AIS-J consisted of a two-factor structure: 'nocturnal sleep problem' (items 1-5) and 'daytime dysfunction' (items 6-8). Internal consistencycoefficients ranged from 0.78 to 0.88. Correlations between the AIS-J and the aforementioned authorized scales were 0.81 and 0.85, respectively. Scores on the AIS-J were significantly higher for the insomnia group than for the control group. The AIS-J cut-off value for identifying pathological insomnia was estimated at 6 points or more, and the AIS-J-nocturnal cut-off value was estimated at 4 points or more.
The AIS-J has sufficient validity and diagnostic utility.
本研究旨在开发和验证雅典失眠量表（AIS-J）的日文版。
使用回译设计创建 AIS-J。共招募了 477 名慢性失眠门诊患者和 163 名普通社区居民。要求参与者完成 AIS-J 以及另外两个失眠量表 - 匹兹堡睡眠质量指数和失眠严重程度指数的日文版。
AIS-J 由两个因素结构组成：“夜间睡眠问题”（项目 1-5）和“日间功能障碍”（项目 6-8）。内部一致性系数范围为 0.78 至 0.88。AIS-J 与上述授权量表之间的相关性分别为 0.81 和 0.85。AIS-J 得分在失眠组中明显高于对照组。用于识别病理性失眠的 AIS-J 截断值估计为 6 分或更高，AIS-J-夜间截断值估计为 4 分或更高。
AIS-J 具有足够的有效性和诊断实用性。
