Objectives To evaluate the reliability and validity of Quality of Life Scale in Patients with Viral Myocarditis (QOL-VMC Scale) after item selection.
Methods 100 patients who were diagnosed viral myocarditis and 100 healthy volunteers filled in the QOL-VMC Scale. Methods such as t-test, correlation analysis and multivariant stepwise regression analysis were applied to evaluate the reliability and validity.
Results The evaluation showed that the scale had good test-retest reliability, split-half reliability, consistency reliability, content validity and discriminant validity. The overall construct validity basically matched the initial scale idea of designers.
Conclusions The QOL-VMC Scale is proved with good reliability and validity, so it can be used as the supplement of clinical indexes to evaluate the therapeutic effect of viral myocarditis.
