Objective To evaluate the reliability and validity of the previously developed Measurement Tool for Atrial Fibrillation Patient Experience of Catheter Ablation.Methods A survey was conducted using the previously developed Measurement Tool for At-rial Fibrillation Patient Experience of Catheter Ablation among 469 atrial fibrillation patients admitted to two tertiary hospitals in Shanghai.Results Exploratory factor analysis extracted five common factors （comfort management experience, information and communication experience, operational and technical quality experience, emotional support experience, and service process and responsiveness experience）, explaining 67.533% of the total variance. Confirmatory factor analysis established a first-order five-factor model with satisfactory fit indices after modification （χ2/df=1.544, RMSEA=0.046, GFI=0.824, RMR=0.050, CFI=0.940, NFI=0.849, IFI=0.941, TLI=0.934）.The overall Cronbach′s α coefficient of the tool was 0.918, the Guttman split-half reliability coefficient was 0.944, and the test-retest reliability coefficient was 0.996; the Cronbach′s α coefficients of each dimension ranged from 0.896 to 0.944, and Guttman split-half reliability coefficients ranged from 0.869 to 0.957.Conclusion The measurement tool has good reliability and validity. It can be used as a specialized tool for evaluating patient experience, providing a basis for the assessment of the effectiveness of specialized intervention measures.
