Sleep Quality Questionnaire Test - Symptoms and Signs

sleep

This brief self-report measure assesses a respondent’s perceived sleep quality and related sleep complaints over a recent period. The Sleep Quality Questionnaire is intended to support rapid clinical screening and baseline characterization of subjective sleep.

The instrument includes 6 items and typically takes about 2 minutes to complete. Items query common domains of sleep and restorative functioning, allowing clinicians to summarize overall perceived sleep quality and track change over time.

In practice, the Sleep Quality Questionnaire may be used to monitor response to interventions for insomnia and other sleep-related concerns and to guide follow-up assessment as needed. It is commonly cited in the sleep literature (Buysse, Reynolds, Monk, Berman, & Kupfer).
