It differentiates "poor" from "good" sleep by measuring seven subscales: Subjective Sleep Quality, Sleep Latency, Sleep Duration, Habitual Sleep Efficiency, Sleep Disturbances, Use of Sleeping Medication, and Daytime Dysfunction over the last month.
Overall, there was no statistically significant difference between men and women with regards to sleep duration, sleep latency, daytime dysfunction, sleep efficiency, sleep medicine use or overall sleep quality (data not shown).
The PSQI obtains a general measure of sleep quality, and the total score is derived from seven subscales: sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbance, sleep medication, and daytime dysfunction.
The PSQI is a standardized self-rating questionnaire which evaluates seven components of sleep quality, including subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction.
The PSQI differentiated "poor" from "good" sleep by measuring the following seven areas: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction.
The PSQI, which was used to screen potential participants for insomnia, includes 19 self-reported items and uses an algorithm to derive a global score from components of sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbance, use of sleeping medication and daytime functioning [23].
There were no significant differences in sleep efficiency, sleep-onset latency, or REM latency.
Total sleep time, sleep efficiency, sleep-onset latency and wake after sleep onset will be calculated with ActiLife 6 (ActiGraph Inc).
Sleep efficiency was calculated as sleep duration divided by TIB multiplied by 100 (reported as percentage).
Sleep efficiency: percentage ratio between total sleep time and time in bed (total sleep time/time in bed * 100).
Sleep efficiency (SE) and wake after sleep onset (WASO) improved significantly after the discontinuation of third-generation hypnotics (Table 3).
