Obstructive sleep apnea (OSA) is a condition with serious medical and psychosocial consequences. However, poor adherence with nasal continuous positive airway pressure (CPAP) treatment limits the effectiveness of treatment. Behavior change factors offer one avenue of research to better understand the correlates of CPAP adherence. ⋯ The results suggest that social-cognitive factors may be associated with CPAP adherence in experienced CPAP users. The principal advantage to these theory-driven and empirically validated factors is that they are modifiable and can provide the basis for effective interventions to increase CPAP adherence.
