Purpose: The objective of this study was to assess the utility of a fourth-generation multi-theory model (MTM) in explaining the intention for initiation and sustenance of PAP adherence among newly diagnosed sleep apnea patients.
Patients and Methods: For this cross-sectional study, data were collected at a private sleep center located in the Southeastern United States. A total of 138 newly diagnosed patients with sleep apnea who had been prescribed PAP therapy completed a valid and reliable 41-item MTM instrument. Stepwise multiple regression modeling was conducted to assess MTM based explanatory variables of PAP adherence in this study sample.
Results: MTM constructs namely participatory dialogue (β = 0.17, p = 0.014), behavioral confidence (β = 0.48, p < 0.001), and changes in the physical environment (β = 0.26, p = 0.001) were statistically significant predictors of the intention for initiation of PAP therapy and accounted for 53.5% of the variance. Emotional transformation (β = 0.57, p < 0.001), changes in the social environment (β = 0.16, p = 0.016), and practice for change (β = 0.16, p = 0.047) were statistically significant predictors of the intention for sustenance of PAP therapy and accounted for 60.6% of the variance.
Conclusion: The MTM was found to be a promising theoretical model in explaining the intention for initiation and sustenance of PAP therapy.
