The health belief model and compliance with CPAP treatment for obstructive sleep apnoea

Obstructive sleep apnoea (OSA) is a disorder that severely disrupts sleep and may lead to severe long- and short-term health consequences. Continuous positive airway pressure (CPAP) is an effective treatment for OSA, but compliance with CPAP is often poor. Forty participants diagnosed with OSA completed a questionnaire based on the health belief model after a one-night first-time trial of CPAP treatment. After a subsequent 1-month period of CPAP use, electronic usage records were downloaded and analysed. Perceived benefits of CPAP use and perceived barriers to use showed multivariate associations with the mean number of hours of daily CPAP use, and perceived benefits of CPAP use was inversely associated with the percentage of days that CPAP was not used. Participants' confidence in their ability to use CPAP showed significant univariate, but not multivariate, relationships with both variables. Findings suggest that patients may benefit from greater levels of information and instruction in CPAP use.
