Abstract: Objective:To translate the Cardiac Symptom Survey and analyze its reliability and validity in the post-valvular heart replacement survey and to provide the basis for the clinical application of this scale.Methods:The symptoms of 233 patients after heart valve replacement were investigated in Suining Central Hospital by Chinese version of the Cardiac Symptom Survey. The reliability of the scale was evaluated by Cronbach'α coefficient and the split half coefficient, the validity of the scale was evaluated by exploratory factor analysis and content validity index.Results:The internal consistency coefficient of the Chinese version of the Cardiac Symptom Survey ranged from 0.875 to 0.968, both above 0.870.The split half coefficient was 0.699,which demonstrated better internal consistency.The content validity index of the Chinese version of the Cardiac Symptom Survey ranged from 0.84 to 1.00.Factor analysis got five factors, which explained 68.133% of the total variance.Conclusions:The Chinese version of the Cardiac Symptom Survey has good reliability and validity in the investigation of the symptoms of patients after heart valve replacement, and can be used for the investigation and management of the symptoms of patients after heart valve replacement.
