Insomnia Test

When sleep difficulties persist, a brief standardized measure can help quantify their perceived impact and guide next steps. Developed by Charles M. Morin, the Insomnia Test uses the Insomnia Severity Index (ISI) — one of the most widely used insomnia instruments in clinical and research settings — to assess perceived insomnia-related symptoms and associated distress. It contains 7 items and typically takes about 2 minutes to complete.

Why Take an Insomnia Test

Many people who struggle with sleep normalize it — attributing poor sleep to stress, age, a busy schedule, or simply "being a bad sleeper" without ever quantifying how significant the problem actually is. This makes it hard to know whether difficulty falling asleep or staying asleep a few nights a week represents a passing rough patch or a pattern serious enough to warrant treatment.

A structured test for insomnia removes this ambiguity. Rather than relying on a vague sense that sleep "isn't great," the ISI asks specific questions about sleep onset difficulty, sleep maintenance, satisfaction with current sleep, how noticeable the impairment is to others, and how much distress it causes — producing a concrete severity score with established clinical thresholds. This specificity matters both for individuals deciding whether to seek help and for clinicians tracking whether treatment is actually working.

This insomnia quiz is especially useful for people whose stress, pain, medications, or chronic illness may be affecting sleep, and for anyone already working with a psychologist or psychiatrist who wants a quick, repeatable way to track whether insomnia symptoms are improving over time.

What the Assessment Measures

The ISI rates insomnia severity across several core dimensions of nighttime and daytime functioning:

• Sleep onset difficulty — how hard it is to fall asleep at the start of the night
• Sleep maintenance difficulty — how often sleep is disrupted by waking during the night or too early in the morning
• Sleep satisfaction — overall satisfaction or dissatisfaction with current sleep patterns
• Interference with daytime functioning — how much sleep problems disrupt daily activities, concentration, mood, or energy
• Noticeability and distress — how apparent the sleep problem is to others and how worried or concerned the person feels about it

Total scores range from 0 to 28. Scores of 0–7 indicate no clinically significant insomnia, 8–14 subthreshold insomnia, 15–21 moderate insomnia, and 22–28 severe insomnia warranting clinical attention.

Who This Assessment Is For

This Insomnia Test is appropriate for anyone who struggles to fall asleep, stay asleep, or wake feeling unrefreshed and wants to understand how severe their sleep problems actually are. It is also used by people working with a psychologist or psychiatrist to track insomnia symptoms over time and evaluate whether treatment is helping, and by those whose stress, pain, medications, or chronic illness may be affecting sleep and want to quantify the impact on daily life.

Clinical Validity and Use in Practice

The ISI is one of the most extensively validated and widely used insomnia measures worldwide, cited in thousands of clinical and research studies. It can be used in clinical settings to support screening and severity monitoring, and in research to track change over time based on patient-reported outcomes. Results from this insomnia test should be interpreted alongside clinical history — the ISI is a screening and severity-rating tool, not a standalone diagnostic instrument. Where scores fall in the moderate-to-severe range, consultation with a physician or sleep specialist is recommended, particularly to rule out underlying medical or psychiatric contributors.
