Sleep duration and sleep efficiency are both identified as core measurable dimensions of sleep health {fact:2, fact:3, fact:4} and are both assessed as distinct components within the Pittsburgh Sleep Quality Index (PSQI) [1], while both are also utilized as variables in sleep-related regression analyses [2].

claimSleep health comprises several measurable dimensions: sleep duration (total amount of sleep per 24-hour day), sleep continuity or efficiency (ease of falling asleep and returning to sleep), timing (placement of sleep within the 24-hour day), alertness/sleepiness (ability to maintain attentive wakefulness), and satisfaction/quality (subjective assessment of “good” or “poor” sleep).

claimRegression analyses indicate that Pittsburgh Sleep Quality Index (PSQI) scores significantly predict performance on cognitive measures (RAVLT, Stroop Test, RPM, and WCST) even after controlling for demographic variables (age, gender, socioeconomic status) and actigraphy-measured sleep duration and efficiency.
referenceThe Pittsburgh Sleep Quality Index (PSQI) is a validated instrument used to assess multiple aspects of sleep quality over the previous month, consisting of 19 items that generate seven component scores: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, usage of sleeping medications, and daytime dysfunction.
