Abstract: Objective To provide the research basis for the next step of training needs investigation. Methods The item pool of advance care planning training needs assessment tool was initially constructed by literature analysis and data review. Then the English items were translated and adjusted according to the Brislin translation model, and the items were revised by Delphi expert consultation and pre-survey. Results After literature analysis and data review, 23 items were identified, involving three themes: basic knowledge, specialized knowledge and communication skills. After translation and back translation, the overall semantic evaluation of the scale was high, the semantic equivalence of the items was 78.6% to 100.0%, and the semantic equivalence of the scale was 82.6% to 100.0%. After two rounds of consultation, the enthusiasm of experts was 100%, the degree of expert authority was 0.87, the coordination coefficient of expert consultation was 0.271 and 0.353, the mean importance of each item ranged from 4.29 to 5.00, and the coefficient of variation ranged from 0.05 to 0.11. Among the 40 medical staff who evaluated the face validity of the scale, the recognition of each item of the scale was 87.5% to 100.0%. Conclusion The developed training needs assessment tool of advance care planning for medical workers is reasonable as a whole. The Chinese-translated items can provide a research basis for the next step of training needs investigation.
