Recorded and Reported Sleep in Chronic Primary Insomnia

The relation between polysomnography and subjective sleep and its dependence on age – poor sleep may become good sleep

“…The results suggest that perceived good sleep in this representative group of women involves long sleep, high sleep efficiency, low WTSP and few awakenings. Similar diary‐type cross‐sectional studies have failed to show clear results in clinical groups (Carskadon et al ., ; Coleman et al ., ; Frankel et al ., ; Krystal et al ., ), possibly because of a restriction of range in subjective sleep variables. The present results are in line with the results from non‐clinical groups in which sleep continuity variables were associated with morning ratings of sleep quality (Baekeland and Hoy, ; Hoch et al ., ; Kryger et al ., ; Mendelson et al ., ; Saletu, ).…”

Sleep spindles in chronic psychophysiological insomnia

“…It is now well documented that individuals suffering from insomnia and good sleepers differ on subjective measures of SOL, WASO, and TST [10,30,31]. Our results corroborate previous studies as individuals suffering from psychophysiological insomnia reported taking longer to fall asleep, spending more time awake during the night, and sleeping less compared with good sleepers.…”

A Multifactorial Approach to Sleep and Its Association with Health-Related Quality of Life in a Multiethnic Asian Working Population: A Cross-Sectional Analysis

“…This demonstrates the added benefit of a multifactorial approach to measuring sleep, as the use of a subjective measurement alone did not show a relationship with physical health-related quality of life. While subjective and objective sleep measurements share commonalities and are conceptually equivalent, previous research has demonstrated inconsistencies between the measurements [15,28,52,53,54,55]. In line with previous research, our study found that subjective and objective sleep measurements were either weakly or not significantly correlated [15,28,52,53,54,55].…”
