Objective Cognitive interviews were used to explore the Chinese target population’s cognition and understanding of Attitudes Related to Trauma-Informed Care Scale（ARTICS） in the Chinese context. The purpose was to verify the consistency of the language expression of the revised ARTICS and the original scale. Methods Using the purpose sampling method,26 psychiatric nurses who met the inclusion criteria were selected as interviewees from a secondary mental health centre in a district of Shanghai. 2 rounds of cognitive interviews were conducted to explore the respondents’ understanding of the items of the Chinese version of ARTICS. The items with ambiguities were revised according to the interview results to form the Chinese version of ARTICS. Results ARTICS consists of 35 items across 5 dimensions. The results of the first round of interviews showed that some respondents had ambiguities in the semantic expression and understanding of the 6 items in the scale,and these items were modified after discussion. The results of the second round of interviews showed that the content of the revised items was semantically consistent with the original scale. Conclusion The use of cognitive interview can help the scale adapt to different cultural background,improve the target population’s understanding and acceptance of scale items,reduce measurement errors caused by misunderstanding of certain items,and improve the response rate of the scale.
