Abstract

Background: This study aimed to validate the Korean version of the Patient-Reported Outcome Measurement Information System 29 Profile V2.1 (K-PROMIS-29 V2.1) in a sample of patients with chronic pulmonary diseases (CPDs).

Methods: Participants were recruited from the respiratory disease outpatient clinics of Samsung Medical Center in Seoul, South Korea, from September to October 2018. Participants completed a survey questionnaire, including the K-PROMIS-29 V2.1 and Short Form Health Survey version-2.0 (SF-36v2). Modified Medical Research Council (mMRC) and chronic obstructive pulmonary disease (COPD) Assessment Test (CAT) scores were obtained these scores from electronic medical records (EMRs). Exploratory and confirmatory factor analyses (CFA) and Pearson's correlations were used to evaluate the reliability and validity of the K-PROMIS-29 V2.1.

Results: The mean age [standard deviation (SD)] was 62.8 (12.0) years, and 19.2% had less than middle-school education. Disease types included bronchiectasis (n=46, 24.5%), COPD (n=45, 23.9%), nontuberculous mycobacterial lung disease (n=25, 13.3%), interstitial lung disease (n=22, 11.7%), and others (n=50, 26.6%). Cronbach's alpha coefficients of the 7 subdomains in the K-PROMIS-29 V2.1 ranged from 0.77 to 0.96, indicating satisfactory internal consistency. In CFA, the goodness-of-fit indices were high (comparative fit index =0.90, standardised root mean residual =0.06). Moderate correlations were observed between comparable subscales of the K-PROMIS-29 V2.1 and those of the SF-36v2 (r=0.55-0.70) and CAT (r=-0.80 to 0.70).

Conclusions: The findings of this study suggest that the K-PROMIS-29 V2.1 is a reliable and valid measure for assessing a broad range of health-related quality-of-life domains in patients with CPDs.
