Development of a knowledge, attitude, and practice scale for cardiac rehabilitation for parents of children with heart disease

Published:January 09, 2023DOI:


      • A Cardiac Rehabilitation Knowledge, Attitude, and Practice Scale was developed.
      • The scale has good reliability and validity.
      • Knowledge, attitude, and practice theory was used.



      We aimed to (i) develop a Cardiac Rehabilitation Knowledge, Attitude, and Practice Scale for parents of children with heart disease and (ii) test its reliability and validity.


      Based on the theory of knowledge, attitude, and practice, an item pool was constructed through literature review, and 200 parents of children with heart disease were surveyed to test the reliability and validity of the scale.


      The finalized Knowledge, Attitude, and Practice Scale contains three parts, i.e., knowledge, attitude, and practice, with a total of 34 items. The Cronbach alpha coefficient of the total scale was 0.731, the split-half reliability was 0.730, the content validity was 0.956, and the content validity of each item was 0.917–1.


      The Knowledge, Attitude, and Practice Scale of Cardiac Rehabilitation for Parents of Children with Heart Disease has good reliability and validity, and it can be used as a tool to evaluate the knowledge, attitudes, and practices of parents of children with heart disease participating in cardiac rehabilitation.

      Practice implications

      The development of the Cardiac Rehabilitation Knowledge, Attitude, and Practice Scale for parents of children with heart disease is of great significance for carrying out targeted education programs in the future to improve the compliance of children with heart disease with cardiac rehabilitation programs.
