Introduction: The RhinAsthma Patient Perspective (RAPP) was developed in Italian to assess the Health Related Quality of Life (HROoL) impairment in patients with asthma and allergic rhinitis (AR) in daily practice. Aim: To cross-culturally validate the Polish version. Material and methods: The Polish version was administered to patients suffering from asthma and rhinitis in a prospective observational study. Polish RAPP, along with SF-12, ACT, and a Symptomatologic VAS was filled in twice, with a 4-week interval between visits. At visit 2, a Global Rating Scale (GRS) was completed to assess any change in health status. Internal consistency, validity, reliability, discriminant ability and responsiveness to change as well as Minimal Important Difference were determined. Results: The factor and confirmatory analysis revealed a unidimensional structure of RAPP. Internal consistency was satisfactory with Cronbach's alpha (visit 1 = 0.85, visit 2 = 0.89). High reliability (ICC = 0.89 and a CCC = 0.94) was found. Validity analyses showed good correlations of the Polish RAPP with Physical and Mental Component Scores of SF-12. In addition, RAPP adequately discriminated patients on the basis of the asthma control level and rhinitis severity (p < 0.03 for all the analyses), and demonstrated to be sensitive to change. MID value was 1 point. Conclusions: The study confirmed the reliability and validity of the Polish version of RAPP demonstrating that it is a useful tool in the assessment of HROoL in patients with asthma and comorbid allergic rhinitis, in clinical practice.

Abstract

Introduction: The RhinAsthma Patient Perspective (RAPP) was developed in Italian to assess the Health Related Quality of Life (HROoL) impairment in patients with asthma and allergic rhinitis (AR) in daily practice. Aim: To cross-culturally validate the Polish version. Material and methods: The Polish version was administered to patients suffering from asthma and rhinitis in a prospective observational study. Polish RAPP, along with SF-12, ACT, and a Symptomatologic VAS was filled in twice, with a 4-week interval between visits. At visit 2, a Global Rating Scale (GRS) was completed to assess any change in health status. Internal consistency, validity, reliability, discriminant ability and responsiveness to change as well as Minimal Important Difference were determined. Results: The factor and confirmatory analysis revealed a unidimensional structure of RAPP. Internal consistency was satisfactory with Cronbach's alpha (visit 1 = 0.85, visit 2 = 0.89). High reliability (ICC = 0.89 and a CCC = 0.94) was found. Validity analyses showed good correlations of the Polish RAPP with Physical and Mental Component Scores of SF-12. In addition, RAPP adequately discriminated patients on the basis of the asthma control level and rhinitis severity (p < 0.03 for all the analyses), and demonstrated to be sensitive to change. MID value was 1 point. Conclusions: The study confirmed the reliability and validity of the Polish version of RAPP demonstrating that it is a useful tool in the assessment of HROoL in patients with asthma and comorbid allergic rhinitis, in clinical practice.
