Discrepancy between subjective and objective sleep in patients with depression

Abstract

The literature investigating the relationship between objective and subjective sleep in depressed patients is limited and the results are inconsistent. Furthermore, many factors that influence the aforementioned relationship have not been investigated. The present study was carried out to clarify the characteristics of self-estimation of sleep in depressed patients. Sleep was estimated concurrently using a sleep log and polysomnography for 5 consecutive days to investigate the relationship between subjective sleep estimation and objective sleep estimation in 23 patients with major depression ( Diagnostic and Statistical Manual of Mental Disorders, 3rd edn, revised; DSM-III-R). Factors related to a discrepancy between both types of estimation were identified. The subjective total sleep time showed a significant, but moderate, positive correlation (correlation coefficient: 0.63) with the objective total sleep time. The degree of discrepancy was significantly correlated with various objective sleep variables and severity of depression. In the underestimation group in which the subjective total sleep time was shorter than the objective total sleep time, the objective total sleep time and slow-wave sleep time were shorter, age was greater and the extroversion score (Maudsley Personality Inventory) was lower than in the overestimation group in which the subjective total sleep time was longer than the objective total sleep time. The data suggest that subjective sleep estimation in depressed patients is influenced by their objective sleep, severity of depression, age and personality.

“…Thus, our data provide some evidence that patients’ reports of sleep quality reflect objective sleep behaviors. Nevertheless, the lack of stronger and more consistent associations between subjective and objective sleep in the current study is consistent with previous literature reporting discrepancies between subjective sleep reporting and objective sleep measures (Ancoli-Israel et al, 2003; Buysse et al, 2008; Jackowska et al, 2011; Rotenberg, Indursky, Kayumov, Sirota, & Melamed, 2000; Tsuchiyama, Nagayama, Kudo, Kojima, & Yamada, 2003; Van Den Berg et al, 2008). To date, literature examining the relationship between psychosocial resources and sleep has relied mostly on the use of subjective sleep measurements.…”

Subjective and objective evaluation of alertness and sleep quality in depressed patients

“…However, the discrepancies seem to be more pronounced in the present study. A possible explanation can be the fact, that Argyrpoulos et al [7] and Tsuchiyama [8] studied patients with major depression while the present study was based on the observations in patients with minor depression. Another confounding factor can be the wide age range as can be seen in the present study.…”

Subjective sleep, depression and anxiety: inter‐relationships in a non‐clinical sample

“…Studies of the accuracy of subjective perceptions of sleep in depression have produced inconsistent findings (Tsuchiyama et al 2003;Armitage et al 1997), and inaccuracy may increase with greater severity of depression (Argyropoulos et al 2003). An alternative explanation is that these perceptions may be subject to bias that is maintained by depression, or that subjective sleep misperceptions may influence depression.…”
