Coping Processes, Self-Efficacy, and CPAP Use in Adults With Obstructive Sleep Apnea.

: Coping strategies are predictive of 1 week CPAP use. Coping strategies may predict longer-term CPAP use among adults with obstructive sleep apnea (OSA). : To investigate the influence of two coping styles (active and passive) and individual coping processes on CPAP use at 1 week and 1 month; and explore the association between self-efficacy and coping on CPAP use. : CPAP-naïve adults (52.3% male, 90.9% White) newly diagnosed with OSA (AHI ≥ 5 events/hr) from two U.S. clinical sleep centers ( = 66). : A post-hoc analysis from a prospective, longitudinal study that examined influential factors on CPAP use among CPAP-naïve patients with newly diagnosed OSA. The Ways of Coping Questionnaire and the Self-Efficacy Measure for Sleep Apnea were completed immediately after CPAP titration polysomnography. Objective 1 week and 1 month CPAP use (mean hr/night) were the primary outcomes. Descriptive analyses and stepwise multiple linear regression analyses modeling for CPAP use (mean hr/night). : Active coping was significantly associated with greater CPAP use (mean hr/night) at 1 week, but not at 1 month ( = 0.0397; = 0.0556, respectively). Higher Planful Problem Solving was significantly associated with greater average CPAP use at 1 week and 1 month ( = 0.0117, = 0.0378, respectively). Self-efficacy was significantly associated with greater average CPAP use at 1 week ( = 0.0056) and 1 month ( = 0.0056). : Self-efficacy and Planful Problem Solving coping are promising behavioral intervention targets to promote CPAP use in newly diagnosed OSA.
