Abstract:Obstructive sleep apnea (OSA) is characterized by repetitive interruptions in respiration during sleep, which causes excessive daytime sleepiness (Bassiri & Guilleminault, 2000). Nasal continuous positive airway pressure (CPAP) is a highly effective treatment for OSA (American Thoracic Society, 1995). The most common reason for lack of patient benefit from CPAP is low adherence (Kryger, 2000). OSA severity and patient demographics have been inconsistent predictors of CPAP adherence. Research examining the association between psychological variables and CPAP adherence has produced equivocal findings. It is possible that depression may account for some of the low adherence to CPAP. There is an increased prevalence rate of depression in patients with OSA (e.g., Kaplan, 1992) and several symptoms of depression could interfere with adherence to CPAP, including fatigue, poor concentration, hopelessness, cognitive distortions, and increased sensitivity to side effects. Although the effect of depression on adherence to CPAP therapy has been examined (Edinger, Carwile, Mikller, Hope & Mayti, 1994; Sandberg, Franklin, Bucht, Eriksson, & Gustafson, 2001; Stepnowsky, Bardwell, Moore, Ancoli-Israel, & Dimsdale, 2002) each of these studies has serious methodological limitations. In the present study, it was predicted that increased depressive symptoms would be associated with reduced adherence to CPAP and greater functional impairment, after controlling for the severity of OSA. The results show that depressive symptoms were not associated with CPAP adherence. This finding is inconsistent with previous research in several medical populations showing that depression predicts reduced adherence. Further research is needed to determine predictors of reduced adherence to CPAP therapy. Depressive symptoms were associated with self-reported sleep-related problems.
