Frequently asked questions
Is this an insomnia diagnosis?+
No — it's a validated screening tool that mirrors the Insomnia Severity Index. A formal diagnosis requires a clinician.
What's a high score?+
15 or higher on the 0–28 scale indicates moderate-to-severe clinical insomnia. CBT-I is the recommended first-line treatment.
How often should I retake this?+
Every 2–4 weeks while making sleep changes; monthly otherwise. The score is most useful as a trend.
What's the difference between acute and chronic insomnia?+
Acute insomnia lasts under 3 months and usually has a clear trigger. Chronic insomnia occurs 3+ nights per week for 3+ months and typically self-perpetuates through anxiety and conditioning.
Is CBT-I better than sleeping pills?+
Yes — CBT-I produces longer-lasting improvements with no side effects, and it's the official first-line treatment per the American College of Physicians.
Can insomnia be cured permanently?+
Many people see lasting improvement: in clinical trials, 6–8 weeks of CBT-I produced sustained benefit at 1-year follow-up for a majority of participants. Results vary by individual, and insomnia can recur, especially without maintaining good sleep habits.
Does insomnia run in families?+
There's a moderate genetic component (~30–40% heritability), but environment, stress conditioning, and habits drive most cases.
