Physiotherapy adherence and perception in patients with cystic fibrosis: A descriptive study

subject

description

Background: Cystic fibrosis (CF) is a chronic and multisystem disease in which respiratory physiotherapy (RP) has revealed as one of the main pillars of treatment. Aim: This study was aimed at assessing the convergent validity and the internal consistency of a new instrument (CAP-FISIO questionnaire) to measure the adherence and the perception of RP in patients with CF. In addition, we inquired into the correlation of the CAP-FISIO questionnaire outcomes with degrees of self-efficacy and coping of the patients. Methods: This is a descriptive cross-sectional pilot study. Patients with CF were assessed in one temporal moment: 1) anthropometrics; 2) forced Spirometry; 3) adherence and perception of RP by CAP-FISIO questionnaire; 4) self-efficacy scale for stress coping (EAEAE; Godoy et al., 2008); 5) coping strategies questionnaire (COPE-28;Yusoff et al., 2010). Results: The analysed sample consisted of 44 CF patients: age (26±11 years); BMI (18±8 Kg/m2); FVC (3.2±0.8 L); FEV1 (2.1±0.7 L); FEV1/FVC (67.4±14.0 %). The overall internal consistency of the CAP-FISIO questionnaire was quite good (α=0.90), as well as for the constructs CAP-FISIOadherence (α=0.87) and CAP-FISIOperception (α=0.83). Significant correlations were found between the following parameters: Age [CAP-FISIOtotal (ρ=0.56; p Conclusions: Our results point out that the new questionnaire CAP-FISIO has a good internal consistency to measure the adherence and perception degree to RP, particularly in older patients with CF.
