Abstract

OBJECTIVE: To examine the role of objective sleep duration, a novel marker in phenotyping insomnia, and psychological profiles on sleep misperception in a large, general population sample. Sleep misperception is considered by some investigators a common characteristic of chronic insomnia, whereas others propose it as a separate diagnosis. The frequency and the determinants of sleep misperception in general population samples are unknown. METHODS: A total of 142 insomniacs and 724 controls selected from a general random sample of 1,741 individuals (aged ≥20 years) underwent a polysomnographic evaluation, completed the Minnesota Multiphasic Personality Inventory-2, and were split into two groups based on their objective sleep duration: "normal sleep duration" (≥6 hours) and "short sleep duration" (<6 hours). RESULTS: The discrepancy between subjective and objective sleep duration was determined by two independent factors. Short sleepers reported more sleep than they objectively had, and insomniacs reported less sleep than controls with similar objective sleep duration. The additive effect of these two factors resulted in underestimation only in insomniacs with normal sleep duration. Insomniacs with normal sleep duration showed a Minnesota Multiphasic Personality Inventory-2 profile of high depression and anxiety and low ego strength, whereas insomniacs with short sleep duration showed a profile of a medical disorder. CONCLUSIONS: Underestimation of sleep duration is prevalent among insomniacs with objective normal sleep duration. Anxious-ruminative traits and poor resources for coping with stress seem to mediate the underestimation of sleep duration. These data further support the validity and clinical utility of objective sleep measures in phenotyping insomnia.

  • Sleep state misperception in both good and poor sleepers can result in poor self-report estimates of sleep onset latency, although differences between self-report and polysomnography estimates tend to be small.

    “sleep state misperception in both good and poor sleepers can result in poor self-report estimates of sleep onset latency,53 although these differences in sleep onset latency estimates from self-report and polysomnography tend to be small.54”

    From Social media use and adolescent sleep patterns: cross-sectional findings from the UK millennium cohort study (2019) · cites this paper as [53]

    The Methods (Key measurements) define sleep misperception as underestimation of sleep duration, and the Discussion reports it among chronic insomniacs with normal objective sleep duration. The cited paper does not establish that misperception makes sleep-onset-latency self-reports inaccurate in both good and poor sleepers; a search for “sleep onset latency” found it only in reference titles. The sentence attaches a different citation to the claim that latency differences tend to be small. (LLM, conf=0.74)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
