Arrhythmias can cause a profoundly negative impact on a persons daily life, leading to impaired health-related quality of life (HRQOL). Assessment of HRQOL can provide valuable information before, during, and after healthcare interventions for arrhythmias. Objective: The aim was to develop and validate a disease-specific scale evaluating HRQOL in patients with different forms of arrhythmia. Methods: The Arrhythmia-Specific questionnaire in Tachycardia and Arrhythmia (ASTA HRQOL) was developed from a literature review, patient interviews, and expert panel evaluations. This version was then psychometrically evaluated in patients treated with radiofrequency catheter ablation because of different forms of arrhythmias and patients who sought emergency care because of atrial fibrillation. Construct validity was evaluated with item-total correlations, confirmatory factor analyses, and convergent and discriminant validity. Internal consistency was evaluated using Cronbachs alpha. Results: All items reached the expected level of item-total correlations of greater than 0.3 for the total scale. The content validity index was sufficient for all items, as was the total scale (0.86-1.0). The 2-factor confirmatory factor analysis model that included the physical and mental factors showed a better fit between model and data than the 1-factor model did (P less than .001). Convergent and discriminant validities were evaluated in the correlation analyses between the ASTA HRQOL subscales and SF-36 physical and mental dimensions. A strong correlation was found between the hypothesized physical and mental scales. Internal consistency was satisfactory with a lower bound confidence interval (95%) for Cronbachs alpha .70 or greater for all the ASTA HRQOL scales. Conclusions: The ASTA HRQOL questionnaire can be a valuable contribution to HRQOL assessments in patients with different forms of arrhythmia. Until there is more evidence regarding validity and reliability, using both the total and subscale scores is recommended.
