目的 编制ICU护士对重型颅脑损伤（severe traumatic brain injury，STBI）患者目标体温管理（target tem- perature management，TTM）知信行（knowledge，attitude and practice，KAP）问卷并检验其信效度。 方法 以知信行理论为框架，通过文献分析及小组讨论初步构建问卷条目池，再通过德尔菲法和预调查确定问卷初稿。 采用便利抽样法，于2022年10月选取甘肃省4所医院240名ICU护士进行调查，进行问卷信效度检验。 结果 ICU护士对重型颅脑损伤患者目标体温管理知信行问卷共包含3个维度，32个条目。问卷整体内容效度指数为0.955，条目内容效度指数 为0.800~1.000。 探索性因子分析提取4个公因子，累积方差贡献率为58.889%，问卷整体Cronbach’s α系数为0.862，重测信度为0.890；知识、态度及行为维度的Cronbach’s α系数分别为0.713、0.925及0.924，重测信度分别为0.801、0.943 及0.950。 结论 ICU护士对重型颅脑损伤患者目标体温管理知信行问卷具有良好的信效度， 可作为ICU护士对重 型颅脑损伤患者目标体温管理知信行水平的测评工具。

Objective To develop a knowledge，attitude and practice（KAP） questionnaire about intensive care unit （ICU） nurses’ target temperature management（TTM） for patients with severe traumatic brain injury（STBI），and to test its reliability and validity. Methods Using the theory of KAP as the framework，a pool of questionnaire items was initially constructed through literature analysis and group discussion，and then the first draft of the questionnaire was determined by Delphi method and pre-survey. 240 ICU nurses from four hospitals in Gansu Province were selected for the questionnaire survey using convenience sampling method to test the reliability and validity of the questionnaire in October 2022. Results The KAP questionnaire about ICU nurses’ TTM for patients with STBI contained 3 dimensions with 32 items. The overall content validity index of the questionnaire was 0.955，and the content validity index of the items was 0.800~1.000. Exploratory factor analysis extracted 4 main factors with a cumulative variance contribution rate of 58.889% . The overall Cronbach’s α coefficient of the questionnaire was 0.862，the retest reliability coefficient was 0.890. The Cronbach’s α coefficients of the dimensions of knowledge，attitude，and practice were 0.713，0.925，and 0.924 respectively，and the retest reliability coefficients was 0.801，0.943 and 0.950 respectively. Conclusion The KAP questionnaire about ICU nurses’ TTM for patients with STBI has good reliability and validity and can be used as an assessment tool to measure ICU nurses’ KAP of TTM for patients with STBI.
