ABSTRACT
Objectives:
To evaluate the reliability and validity of the Chinese version of the test of the adherence to inhalers (TAI) in Chinese patients with chronic airway disease.Methods:
Based on the English version of TAI, the items of the Chinese version of TAI were determined after forward-backward translation and cultural adaption. Totally, 165 patients with chronic obstructive pulmonary disease (COPD) and asthma were enrolled from Respiratory Clinic of the Second Xiangya Hospital of Central South University from July to November 2021, and a questionnaire survey was conducted using the Chinese version of TAI and the Morisky medication adherence scale 8-item version (MMAS-8). The content validity of the scale was expressed by content validity index (CVI) and the construct validity was analyzed by exploratory factor analysis (EFA). The convergence validity was evaluated by Pearson correlation analysis. The reliability of the scale was expressed by Cronbach's α coefficient, the split-half reliability and test-retest reliability.Results:
The CVI was 0.966. There were 10 items in total. Two factors were extracted from the Chinese version of TAI and the cumulative variance contribution rate was 57.236%. The load value of each item was more than 0.400 and the factor attribution of the item was consistent with the original scale. The total score of the Chinese version of TAI was positively correlated with the total score of the MMAS-8(r=0.835,P<0.001). The Cronbach's α of the overall scale was 0.843, the Guttman's half-reliability coefficient was 0.796 and the test-retest reliability was 0.884 (P<0.001), respectively.Conclusions:
The Chinese version of TAI has good reliability and validity, which may be a reliable tool for evaluating the adherence to inhalers of patients with chronic airway disease in China.
