Brief Summary

Nearly half of all patients with obstructive sleep apnea have insomnia symptoms, and in some, but not all cases, these insomnia symptoms are caused by the obstructive sleep apnea. The purpose of this study is to find out what type of insomnia symptoms are caused by obstructive sleep apnea and therefore most likely to respond to obstructive sleep apnea treatment with continuous positive airway pressure (also known as CPAP) and if additional treatment with cognitive-behavioral therapy for insomnia is beneficial.

Outcome Measures

Primary Outcomes (1)

  • Insomnia Severity Index Score

    Insomnia Severity Index. Minimum: 0. Maximum: 28. Higher scores mean worse outcome. The outcome measure is reported as a change score in which the score at baseline is subtracted from the score at follow-up, thus the more negative the score, the larger the improvement. The total score represents an addition of the questions totals; there is no specific subscale modification required to calculate the total score.

    Between Baseline and Day 42.
