Validation and Reliability Assessment of the Test of Adherence to Inhalers (TAI) in Turkish Patients with Chronic Obstructive Pulmonary Disease (COPD)
OBJECTIVE: Accurate assessment of inhaler adherence is essential for optimizing treatment outcomes in patients with chronic obstructive pulmonary disease (COPD). This study aimed to evaluate the validity and reliability of the Turkish version of the Test of Adherence to Inhalers (TAI) in a multicentre COPD cohort. MATERIAL AND METHODS: (İUBÖ)] were recorded. Construct validity was evaluated using confirmatory factor analysis (CFA), criterion validity was evaluated by agreement with İUBÖ using kappa statistics, and known-groups validity was evaluated by comparing the number of inhaler devices used. Reliability was assessed using Cronbach's alpha coefficients and item-total correlations. RESULTS: = 0.02). Internal consistency was high for both the 10- and 12-item versions (Cronbach's alpha >0.90), with item-total correlations indicating adequate reliability. CONCLUSION: The Turkish version of the TAI is a valid and reliable tool for assessing inhaler adherence in patients with COPD and is suitable for both clinical practice and research settings in Türkiye.
