Abstract

Purpose

The chronic respiratory disease questionnaire (CRQ) has been validated and proved useful in assessing therapies for pulmonary diseases. We translated the CRQ into a Taiwan (Mandarin Chinese) version and surveyed its validity and reliability.

Methods

The CRQ includes 20 items divided into four domains: dyspnea, fatigue, emotional function, and mastery. We followed a forward-back translation procedure to create the Taiwan version. A cross-sectional survey was conducted among outpatients with chronic obstructive pulmonary disease. Participants underwent tests including the CRQ, the medical outcomes study short form (SF-36), the St. George respiratory questionnaire (SGRQ), lung function tests (LFTs), and a graded exercise test (GET). We used Cronbach’s alpha to evaluate the internal consistency of the CRQ, intraclass coefficient for test–retest reliability, and Spearman’s correlation for validity.

Results

Thirty-six men and 4 women (mean age 67.9 ± 9.9 years) were recruited. Evidence of good internal consistency, test–retest reliability, convergent, discriminant, concurrent, and construct validity of the CRQ was shown. Spearman’s correlation showed moderate-to-strong correlation between the CRQ scores and scores of the SGRQ, subscales of the SF-36, and the results of LFTs and GET.

Conclusions

The Taiwan version of the CRQ shows good validity, internal consistency, and test–retest reliability.
