Results: The questionnaire covered 3 dimensions and 56 entries totally with the Cronbach's α coefficient being 0.954, the split-half reliability being 0.950, the test-retest reliability being 0.947, the content validity index (S-CVI) being 0.982, and the content validity index of each entry (I-CVI) being 0.875-1.000. Conclusion: This questionnaire can be used as the tool to evaluate the malignant wound management KAP for oncology nurses due to its good reliability and validity.
