Brief Summary

Obstructive sleep apnea (OSA) is a serious sleep disorder in which a person repeatedly stops breathing or experiences shallow breathing for short periods of time during sleep. The most common treatment for OSA is the use of a continuous positive airway pressure (CPAP) machine, but many people have trouble adhering to the treatment schedule. This study will evaluate the effectiveness of two behavioral therapy programs used in combination with CPAP for improving treatment adherence in people with OSA.
