Bottom Line: To assess the reliability of CAT and Dyspnea-12, Cronbach's α coefficient was calculated.The SGRQ score was correlated with the score of CAT (r=0.86, p<0.0001) and Dyspnea-12 (r=0.80, p<0.0001) in tuberculous destroyed lung patients.We found that Korean version of CAT and Dyspnea-12 are valid and reliable in patients with tuberculous destroyed lung and bronchiectasis.

ABSTRACT

Background: The objective of this study was to assess the validity and reliability of the Korean version of chronic obstructive pulmonary disease assessment test (CAT) and Dyspnea-12 Questionnaire for patients with bronchiectasis or tuberculous destroyed lung.

Methods: For 62 bronchiectasis patients and 37 tuberculous destroyed lung patients, 3 questionnaires including St. George's Respiratory Questionnaires (SGRQ), CAT, and Dyspnea-12 were obtained, in addition to spirometric measurements. To assess the validity of CAT and Dyspnea-12, correlation with SGRQ was evaluated. To assess the reliability of CAT and Dyspnea-12, Cronbach's α coefficient was calculated.

Results: The mean ages of the patients were 60.7±8.3 years in bronchiectasis and 64.4±9.3 years in tuberculous destroyed lung. 46.8% and 54.1% were male, respectively. The SGRQ score was correlated with the score of the Korean version of CAT (r=0.72, p<0.0001) and Dyspnea-12 (r=0.67, p<0.0001) in bronchiectasis patients. The SGRQ score was correlated with the score of CAT (r=0.86, p<0.0001) and Dyspnea-12 (r=0.80, p<0.0001) in tuberculous destroyed lung patients. The Cronbach's α coefficient for the CAT and Dyspnea-12 were 0.84 and 0.90 in bronchiectasis, and 0.88 and 0.94 in tuberculous destroyed lung, respectively.

Conclusion: We found that Korean version of CAT and Dyspnea-12 are valid and reliable in patients with tuberculous destroyed lung and bronchiectasis.

Figure 7: Cumulative frequency distribution of chronic obstructive pulmonary disease assessment test (CAT) score in 37 tuberculous destroyed lung patients.

Mentions: According to the result of Korean version CAT questionnaire, a 73% of the subjects scored less than 20 (Figure 7). In Korean version Dyspnea-12 questionnaire, most of the subjects scored 0 (n=7, 18.9%), and 22 (45.9%) of the subjects scored from 0 to 2, implying that the scores of Korean version CAT and Korean version Dyspnea-12 questionnaire were distributed mainly in the low-score range (Figure 8). Cronbach's α coefficients representing internal consistency of Korean version CAT questionnaire and Korean version Dyspnea-12 questionnaire were 0.88 and 0.94, respectively.
