measurement and results: polysomnography was used to measure sleep architecture, and mood was assessed via self-report each day. compared to restricted sleep opportunity controls, forced awakenings subjects had significantly less slow wave sleep (p < 0.05) after the first night of sleep deprivation, and significantly lower positive mood (p < 0.05) after the second night of sleep deprivation. with these findings, we provide temporal evidence in support of a putative biologic mechanism (slow wave sleep deficit) that could help explain the strong comorbidity between insomnia and depression.

sleep initiation problems did not become more severe with age. problem endorsements appeared to parallel severity trends. percent problem endorsement data are as follows. more sophisticated analyses are on-going to determine the degree to which scd symptom severity predicts the likelihood of problem endorsement, and what other factors may influence the report of sleep satisfaction, and whether these vary with age.
