Claustrophobic tendencies and continuous positive airway pressure therapy non-adherence in adults with obstructive sleep apnea.

Objectives: (1) Determine claustrophobia frequency in adults with obstructive sleep apnea (OSA) after first CPAP night; (2) determine if claustrophobia influences CPAP non-adherence.

Background: Claustrophobia is common among CPAP-treated OSA adults yet few studies have examined the problem.

Methods: Secondary analysis of prospective, longitudinal study of OSA adults (n = 97).
