Health belief model predicts adherence to CPAP before experience with CPAP
Olsen, Sara L., Smith, Simon S., Oei, Tian, & Douglas, James A. (2008) Health belief model predicts adherence to CPAP before experience with CPAP. European Respiratory Journal, 32(3), pp. 710-717.
Adherence to Continuous Positive Airway Pressure (CPAP) therapy for Obstructive Sleep Apnoea (OSA) is often poor. Biomedical indices explain little of the variance in CPAP use. This study tested a Health Beliefs model of adherence to determine the contribution of psychological constructs as compared to biomedical indices in the prediction of CPAP adherence.
77 consecutive patients newly diagnosed with OSA and were naive to CPAP treatment (had never tried CPAP before) completed questionnaires at baseline (prior to CPAP treatment). Questionnaires assessed; outcome expectancy with treatment, self-efficacy, functional outcomes of sleepiness, and perceived risk of negative health outcomes. Physiological data from standard clinical diagnostic sleep study was obtained. CPAP adherence was assessed at 4 month follow-up.
Health Beliefs Model constructs alone explained 21.8% of the variance in CPAP adherence (p<.01), whilst Health Beliefs Model constructs and biomedical indices together explained 31.8% of the variance in CPAP adherence (p=.01). The greatest proportion of CPAP adherence was explained by higher outcome expectancies with treatment, greater functional limitations as a result of sleepiness and lower risk perception.
Results suggest that patients have developed beliefs and expectations about OSA and CPAP even before they have tried CPAP treatment. These beliefs and expectations predict patients’ adherence to effective therapy.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
