1What This Insomnia Self-Assessment Measures
Insomnia is the most common sleep disorder on the planet — affecting roughly 1 in 3 adults in any given year, and meeting criteria for chronic insomnia disorder in about 10–15%. But most people who struggle to fall asleep, wake up at 3 AM, or feel unrefreshed in the morning have never been formally evaluated. This insomnia self-assessment tool fills that gap. It mirrors the Insomnia Severity Index (ISI), the most widely used research-grade insomnia screener, and aligns with the diagnostic criteria for insomnia disorder defined in DSM-5 and the International Classification of Sleep Disorders, Third Edition (ICSD-3).
The questions probe four clinical anchors: difficulty initiating sleep (sleep onset latency), difficulty maintaining sleep (nocturnal awakenings), early morning awakening, and the daytime consequences — fatigue, mood disturbance, cognitive slowing, social impairment. A composite score then tells you whether your symptoms fall into the no-clinical-insomnia, sub-threshold, moderate, or severe range.
