概要	The Sleep Condition Indicator (SCI) is an 8-item self-report scale designed to assess the severity of insomnia symptoms in adults in a manner closely aligned with DSM-5 diagnostic criteria for insomnia disorder. Developed by Espie and colleagues in 2014, it measures the core features of insomnia: difficulty initiating sleep, difficulty maintaining sleep, early morning awakening, daytime impairment, and associated distress. The SCI is increasingly used in clinical practice and research to screen for insomnia, monitor treatment response, and evaluate cognitive-behavioral therapy efficacy.	The Daytime Insomnia Symptom Scale (DISS) is a focused assessment tool measuring the daytime functional consequences and symptoms resulting from nighttime insomnia. Developed within research on sleep disturbance and daytime functioning, it captures the daytime manifestations of poor sleep: fatigue, concentration difficulty, mood disturbance, and functional impairment in work, social, and personal domains. The DISS is particularly valuable in quantifying the real-world impact of insomnia on daily activities and quality of life.
