Objective: This study was conducted to determine the Turkish validity and reliability of the Chronic Obstructive Pulmonary Disease (COPD) Anxiety Scale. Methods: The sample of the methodological and cross-sectional study consisted of 401 patients treated in the Atatürk University Health Research and Application Centre and the Erzurum City Hospital chest diseases clinic. The Descriptive Characteristics Form, COPD Anxiety Scale, COPD Assessment Test (CAT), Modified Medical Research Council Scale (mMRC), and Hospital Anxiety and Depression Scale (HADS) were used as data collection tools. Item-total correlation, exploratory and confirmatory factor analysis, Kaiser-Meyer-Olkin test, Bartlett's Sphericity test, test-retest reliability, parallel forms reliability, and Cronbach's alpha coefficient were calculated. Results: The Kaiser-Meyer-Olkin value was 0.854, and Bartlett's test was significant (p<.05). The scale consists of 18 items and 5 sub-dimensions. The total explained variance was 81.596%. Confirmatory factor analysis fit indices were CFI=0.950 and RMSEA=0.078. The standardized factor loadings of the items were found to range from 0.65 to 0.98. Cronbach's alpha was 0.908 for the whole scale and between 0.782 and 0.933 for the sub-dimensions. In the test-retest reliability analysis, the intraclass correlation coefficients (ICC) ranged between 0.883 and 0.965. The COPD Anxiety Scale and its sub-dimensions showed positive correlations with CAT, mMRC, and HADS (p<.05). Conclusion: The Turkish version of the COPD Anxiety Scale is a valid and reliable measurement tool. It is recommended for assessing COPD-specific anxiety in clinical practice and research.
