Validity and Reliability of the Thai Version of the Cardiac Anxiety Questionnaire-Revised Among Thai Cardiac Patients
Abstract
Objective: To translate and validate the Thai version of the Cardiac Anxiety Questionnaire – Revised.
Material and Methods: This was a descriptive statistic and exploratory factor analysis. The data collection was from March 2020 untill December 2020. From this, 213 acute myocardial infarction patients, aged from 30–59 years, who answered the questionnaire – Revised were included . The internal reliability of identified domains was evaluated using Cronbach’s alpha coefficient >0.7. An item-total correlation coefficient between 0.3 and 0.7. Factor loading ≥0.4 were acceptable as enough to establish a factor. A p-value of less than 0.050 was considered significant.
Results: The Cronbach’s alpha of the Cardiac Anxiety Questionnaire – Revised Thai version was 0.83. Item-total and inter-item correlation coefficients were also tested (r=0.21 to 0.81, r=0.00 to 0.72, respectively). Five factors that explained 65.1% of the total variance were identified. Communalities in each factor; ranging from 0.38 to 0.83. Factor 1 had four items reflecting avoidance (Items 2, 7, 9 and 12). Factor 2 had five items that captured worry and fear (Items 10, 13, 14, 15 and 16). Factor 3 had three items that captured attention (Items 1, 6 and 8). Factor 4 had two items, these two items had high factor loading (>0.80) that explained abnormal symptoms (Items 3 and 4) and factor 5 had four items that reflected safety and seeking (items 5, 11, 17 and 18)
Conclusion: The reliability and validity of the Thai version of the Cardiac Anxiety Questionnaire – Revised was suitable to measure anxiety in Thai acute myocardial infraction patients.
