Administration

Convert the original responses to the seven component scores using the official scoring sheet, then enter those components here.

Seven 0–3 components sum to a global score of 0–21. Raw questionnaire responses must not be added directly.

Higher global scores reflect poorer reported sleep quality. Interpret with the sleep history; no diagnostic conclusion follows from the score.
Bed-partner questions do not enter the global score. Component conversion is required before using this calculator.
