Purpose: Despite the importance of using inhalers concerning chronic obstructive pulmonary disease (COPD), patients generally have problems regarding adherence to medication regimen. The first step in understanding medication adherence is its assessment which requires a reliable tool. The aim of this study was to translate and perform the psychometric assessment of Test of Adherence to Inhalers (TAI).

Patients And Methods: In this cross-sectional study, the 10-item TAI was utilized. Patients with COPD referring to Amir-al-Momenin and Vali-Asr hospitals in Arak, Iran, were the study population. The tool was translated using forward-backward translation, and its validity was evaluated via face validity, content validity, and concurrent validity. The reliability of the tool was assessed using test-retest and Cronbach's alpha.

Results: A total of 100 patients with COPD participated in the study, where the results showed that the tool has a good face validity. The CVR was 0.83, the CVI was 0.95, and the concurrent validity with General Medication Adherence Scale (GMAS) was moderate which was not significant (r = 0.613, p = 0.06). The results of the reliability test further showed that in the test-retest, Pearson correlation coefficient was 0.986, ICC was 0.972, and Cronbach's alpha was 0.986.

Conclusion: The tool was translated to Farsi language, with the results indicating that Farsi TAI is a valid and reliable tool for measuring inhaler adherence in patients with chronic pulmonary disease.
