Abstract
Context: Continous positive airway pressure (CPAP) is the standard treatment for obstructive sleep apnea (OSA) and obesity hypoventilation syndrome (OHS). It's effectiveness is limited due to suboptimal adherence and probably explained by differnte psycho-social features.
Objective: Identify the relationship between psychological variables like locus of control, autoefficacy, negative affectivity (NA) and social inhibition (SI) with one-month CPAP use in patients with OSA & OHS.
Methods: Through a prospective cohort, 40 patients with OSA or OHS virgin to CAP use were included. Previous to followup, patients completed 8 autoapplicable scales: DS-14 for type D personality, SEMSA for autoefficacy, MHLC for locus of control, BIS/BAS por activation/inhibition, mini-IPIP for personality traits, HADS, BDI-II and BAI for anxiety/depression. Patients were evaluated one month later for adherence to CPAP defined as percentage of use >4 hours ≥70% or with mean daily use in minutes (MDUM).
Results: Every point in the NA subscale of DS-14 decreased in 11% the probabilities of adherence while every point in the SI subscale of DS-14 did so in 17%. MDUM decreased in 8.85min (CI95% -17.33/-0.36) for every point in NA and 11.92min (CI95% -22.1/-1.74) for every point increase in SI. Other scales and clinical variables did not predict treatment adherence.
Conclusions: Designers of new interventions to enchance patients with AOS & SOH CPAP adherence should consider NA and SI as personality traits that influence patient outcomes.
