We present a brief, patient-reported outcome measure used to assess patients’ levels of adherence with CPAP treatment. MethodsA questionnaire was developed based on academic literature. We qualitatively tested a pool of 18 items. It was tested in a sample of 174 patients from the Hospital La Princesa. Next, 1021 patients from Catalonia were evaluated. Results5 items were removed. Nominal groups referred to three areas: general knowledge about OSA and its risks; CPAP treatment information and expectations; CPAP use, monitoring, and confidence with its use. The 13 retained items maintained the same meaning as the original questionnaire (r=.986; p<.001) and the three proposed dimensions detected a significant increase in general knowledge of OSA (t[173]=8.097, p<.001); CPAP treatment information (t[173]=15.170, p<.001); and CPAP use (t[173]=14.642, p<.001). The final 12-item version was reliable (CRI=.793) and its internal structure was adequate (χ2[51]=72.073; p=.027, CFI=.967, RMSEA=.020 [.000, .030]). Women had a better general knowledge of OSA (t[1,018]=2.190, p=.029), CPAP treatment information (t[1,018]=2.920, p=.004), and higher overall OSA-CPAP scores (t[1,018]=3.093, p=.002). Scores were positively related to quality of life and motivation, adherence was positively related to CPAP use and monitoring, and the total score was negatively related to daytime sleepiness. ConclusionsThe interview could help clinicians prevent some dropouts by targeting patients with lower adherence. It's a tool for assessing patient adherence to CPAP and to promote strategies through education and external motivational stimuli. ER -
