The eight-item Athens Insomnia Scale (AIS-8) is an instrument that has been used frequently to assess insomnia problems. Previous research on adults has found that the AIS-8 functioned as a sole component. This study aimed to examine the prevalence rates of insomnia problems on the AIS-8, the factor structure of the AIS-8 in adolescents and its associations with demographic characteristics and depression in adolescents. A total of 8319 adolescent students (4334 girls and 3985 boys, mean age = 14.7 years, standard deviation = 1.7 years) in southern Taiwan were recruited into this study and completed the AIS-8. We performed an exploratory factor analysis to examine the factor structure of the AIS-8, and used the parallel analysis for making decisions regarding factor retention. We also used multiple regression analysis models to determine the associations between insomnia and demographic characteristics and depression. The results found that a high proportion of adolescents had insomnia problems as measured by the AIS-8. The AIS-8 was composed of two different factors when used among a large adolescent population, including insomnia symptoms (factor 1) and subjective sleep and daytime distress (factor 2). While being male, being younger, and having depression were associated positively with the severity of insomnia symptoms (factor 1), being older, living in urban areas, and having depression were associated positively with the severity of subjective sleep and daytime distress (factor 2). Clinicians and researchers should consider the different meanings of the two factors of the AIS-8 when using this tool to assess insomnia problems in adolescents.
八条目雅典失眠量表（AIS-8）是一种常用于评估失眠问题的工具。先前对成年人的研究发现，AIS-8 作为单一成分发挥作用。本研究旨在探讨 AIS-8 评估青少年失眠问题的发生率、AIS-8 在青少年中的因子结构及其与人口统计学特征和抑郁的关系。本研究共招募了台湾南部 8319 名青少年学生（4334 名女生和 3985 名男生，平均年龄=14.7 岁，标准差=1.7 岁），并完成了 AIS-8 量表。我们进行了探索性因子分析来检验 AIS-8 的因子结构，并使用平行分析来决定因子保留。我们还使用多元回归分析模型来确定失眠与人口统计学特征和抑郁之间的关系。结果发现，大量青少年存在 AIS-8 测量的失眠问题。在大规模青少年人群中，AIS-8 由两个不同的因子组成，包括失眠症状（因子 1）和主观睡眠和日间困扰（因子 2）。男性、年龄较小和抑郁与失眠症状严重程度呈正相关（因子 1），而年龄较大、居住在城市地区和抑郁与主观睡眠和日间困扰严重程度呈正相关（因子 2）。临床医生和研究人员在使用 AIS-8 评估青少年失眠问题时，应考虑该工具两个因子的不同含义。
