Although various instruments have been developed to evaluate insomniac symptoms in individuals, none of them are based on the International Classification of Sleep Disorder, 2nd (ICSD-II). The purpose of this study is to develop a new scaling system, the Insomnia Screening Scale (ISS) to fit the new diagnostic criteria.
Study 1 was conducted to formulate the new items of the insomnia screening scale (ISS), which were divided into four major subscales, and establish the reliability and validity of the ISS in clinical insomniac subjects. Study 2 tested the external validity of the ISS, which was used in a community survey, and investigated the relationship between ISS and daytime function, especially working memory.
The final version of the ISS has good internal consistency (α = 0.87-0.98), and explains 64% of the variance. The insomnia group had poor working memory performance on the cognitive tasks.
The ICSD-II based ISS is a reliable and valid instrument for evaluating an individual's insomniac symptoms. The major difference between the ISS and the previous instruments is that the ISS not only assess the subjective insomniac and daytime symptoms but also examines the sleep environment and sleep opportunities of the participants.
尽管已经开发出各种仪器来评估个体的失眠症状，但没有一种是基于国际睡眠障碍分类，第 2 版（ICSD-II）的。本研究的目的是开发一种新的评分系统，即失眠筛查量表（ISS），以适应新的诊断标准。
研究 1 用于制定新的失眠筛查量表（ISS）项目，该量表分为四个主要分量表，并在临床失眠患者中建立 ISS 的可靠性和有效性。研究 2 测试了 ISS 的外部有效性，该量表用于社区调查，并研究了 ISS 与日间功能的关系，特别是工作记忆。
ISS 的最终版本具有良好的内部一致性（α=0.87-0.98），并解释了 64%的方差。失眠组在认知任务上的工作记忆表现较差。
基于 ICSD-II 的 ISS 是一种可靠有效的评估个体失眠症状的工具。ISS 与以前的仪器的主要区别在于，ISS 不仅评估主观的失眠和日间症状，还检查参与者的睡眠环境和睡眠机会。
