Always sleeping poorly? ISI quantifies insomnia severity
The ISI is a common self-rating insomnia tool, assessing falling asleep, staying asleep, early waking, satisfaction, daytime impact, others' awareness and distress — total 0-28: 0-7 not clinically significant, 8-14 subthreshold, 15-21 moderate, 22-28 severe. For chronic insomnia, CBT-I is preferred over medication. Free; scored locally for tracking sleep change. A screen, 診断ではありません.

よくある質問
ISIは何点で不眠とみなしますか？
Generally above 8 suggests an insomnia tendency, 15+ moderate, 22+ severe. Whether treatment is needed depends on your situation and a doctor's judgement.
不眠は必ず睡眠薬が必要ですか？
No. The international first-line for chronic insomnia is CBT-I, not medication first. Whether and what to prescribe is a doctor's decision after assessment.
