Sleep (ISI)
  • What this measures
    A brief screen for sleep difficulties — problems with falling asleep, staying asleep, and overall sleep satisfaction over the past two weeks.
  • How we calculated your result
    We sum your seven answers (0–4 each) for a total of 0–28, then convert that to a Health % so higher means healthier sleep quality.
  • What your score means
    0–7: No clinically significant insomnia.
    8–14: Mild insomnia symptoms.
    15–21: Moderate insomnia symptoms — may affect daytime functioning.
    22–28: Severe insomnia — likely to impact health and quality of life.
  • Why we use this method
    The Insomnia Severity Index (ISI) is a validated, widely used measure that correlates strongly with clinical diagnosis and treatment outcomes.
  • What’s next
    If your score was 15 or higher, you’ll find the full ISI below (under Suggested Assessments) and resources for cognitive-behavioral or lifestyle approaches to improve sleep.
