Objective：To establish a systematic and scientific evaluation index of continuing nursing for CHD after percutaneous coro－nary intervention（PCI），and to test the reliability and validity. Methods：Based on literature analysis and qualitative research，the effectiveness evaluation index of patients with CHD after PCI and was developed to determine the content index by Delphi method. Nine experts were invited to perform CVI. The reliability and validity of the index were tested among 231 patients with CHD after PCI in hospital another. Results：The final evaluation index consisted of 4 first indicators，15 second indicators and 35 third indicators. The Cronbach’s alpha was 0.926 for the total index. The Cronbach’s alpha of 4 first indicators were 0.600，0.768，0.918，0.798. The split half reliability was 0.952. The index content validity index was 0.890. Factor analysis was used to extract 6 factors and the cumulative variance contribution rate was 69.26%. Conclusion：The evaluation index is scientific，reliable，practical and feasible. It can evaluated the quality of continuous nursing scientifically and effectively.
