Sleep Quality Assessment
Use when asked to administer, score, or explain a Sleep Quality Assessment — using the Pittsburgh Sleep Quality Index (PSQI) — grounded in FormExamples/form-examples.
Sleep quality evaluation using the PSQI (Pittsburgh Sleep Quality Index), covering sleep habits, latency, duration, efficiency, disturbances, and daytime dysfunction.
Scoring
Instrument: PSQI. Range 0–21.
- 0–5 — good sleep quality.
- 6–10 — poor sleep quality.
- 11–21 — very poor sleep quality.
What it covers
Demographics; sleep habits; sleep latency; sleep duration; sleep efficiency; sleep disturbances; daytime dysfunction; sleep medication use; and medical and lifestyle factors.
Common pitfalls
- Scoring PSQI from a single night's recall rather than a representative period — the PSQI is designed to capture typical sleep patterns over the past month, not an unusual single night; anchoring on one atypical night skews the result.
- Missing sleep medication use as a confounder — medication-assisted sleep can produce a misleadingly "good" score that doesn't reflect underlying sleep quality without the medication.
- Not investigating a poor score for an underlying cause — a high PSQI total is a prompt to look for contributing factors (sleep apnea, restless legs, mood disorder, pain, environmental factors), not an endpoint in itself.
