概要	The IRLS is a 10-item clinician-administered rating scale designed to assess the severity of symptoms in patients with restless legs syndrome (RLS). Developed and validated by Walters and colleagues in 2003 for the International Restless Legs Syndrome Study Group, it is the most widely used disease-specific severity measure for RLS in clinical practice and research. The scale captures the cardinal features of RLS—nocturnal leg discomfort, urge to move, sleep disruption, and functional impairment—across multiple dimensions.	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.
