OBJECTIVE: The purpose of this study was to establish and evaluate the validity and reliability of the Vietnamese version of the inhaler use scale for chronic obstructive pulmonary disease patients.

MATERIAL AND METHODS: This study was conducted with 150 participants who were admitted to the Outpatient Department of Pulmonary Diseases in Vietnam, using a face-to-face interview technique. The Kaiser-Meyer-Olkin test, Bartlett’s test, and exploratory factor analysis were used to assess construct validity. Cronbach’s alpha coefficient and intraclass correlation coefficient were used to evaluate the reliability of the scale.

RESULTS: In the results of exploratory factor analysis with eigenvalues > 1.00, 3 factors of scale appeared. The total variance of the questionnaire was 78.78%, where variances of each component were 34.16%, 26.88%, and 17.73%, respectively. Cronbach’s alpha coefficients of scale in the first test and re-test after 4 weeks were 0.913 and 0.901, respectively. The intraclass correlation coefficient was 0.826.

CONCLUSION: The validity and reliability of the Vietnamese version of the inhaler use scale study were found to be equivalent to the original author-developed scale and it can be applied to measure the factors affecting behavioral intention in Vietnamese chronic obstructive pulmonary disease patients.
