This study was aimed to translate and culturally adapt the MDP into Turkish and investigate the psychometric properties of this adapted version in outpatients with respiratory disease.Methods: A total of 170 outpatients with respiratory disease were included. Activity-related and resting conditions situations were evaluated. We formulated 17 hypotheses for each MDP domain to assess the construct validity and the correlations were investigated between the MDP and measures of body mass index, pulmonary function test, other dyspnea assessments, anxiety, depression, and health-related quality of life. To investigate the test-retest reliability, it was administered again after one hour and one week.Results: Internal consistency of the MDP was excellent (Cronbach’s alpha coefficients ranged from 0.89 to 0.93). Overall, 64 of the 68 predetermined hypotheses (94%) were confirmed to test construct validity. The MDP showed excellent test-retest reliability for a one-hour period (intraclass correlation coefficient values ranged from 0.98 to 0.99). However, the test-retest reliability decreased moderate-to-high after a one-week period (0.53 to 0.80).Conclusions: The MDP was successfully translated and culturally adapted into Turkish and this version showed good psychometric properties including the factorial structure, internal consistency, test-retest reliability, and construct validity to assess multidimensional aspects of dyspnea.FootnotesCite this article as: European Respiratory Journal 2020; 56: Suppl. 64, 2464.This abstract was presented at the 2020 ERS International Congress, in session “Respiratory viruses in the "pre COVID-19" era”.This is an ERS International Congress abstract.
