To develop a scale that measures barriers to perioperative hypothermia prevention (BPHP) as perceived by anesthesiologists and nurses.
A methodological and prospective psychometric study.
Based on the theoretical domains framework, the item pool was created through a literature review, qualitative interviews, and expert consultation. The scale was pretested with a sample of 154 key stakeholders in perioperative temperature management and then field tested with 416 anesthesiologists and nurses working at three hospitals in Southeast China. Item analysis, and reliability and validity analysis were performed.
The average content validity index was 0.94. According to exploratory factor analysis, seven factors were obtained that could explain 70.283% of the total variance. Confirmatory factor analysis showed excellent or acceptable goodness-of-fit indices. The reliability analysis demonstrated that the scale had high internal consistency and temporal stability, with Cronbach's α, split-half coefficient and test-retest values of 0.926, 0.878 and 0.835, respectively.
The BPHP scale meets the psychometric criteria for reliability and validity and promises to be a useful quality measure for IPH management during the perioperative period. Further investigations on educational or resource needs and the development of an optimal perioperative hypothermia prevention protocol to narrow the gap between research evidence and clinical practice should be performed.
开发一种衡量麻醉师和护士感知的围手术期低体温预防障碍（BPHP）的量表。
方法学和前瞻性心理测量研究。
基于理论领域框架，通过文献回顾、定性访谈和专家咨询创建了项目池。该量表在围手术期体温管理的 154 名关键利益相关者样本中进行了预测试，然后在中国东南部的 3 家医院对 416 名麻醉师和护士进行了现场测试。进行了项目分析、信度和效度分析。
平均内容效度指数为 0.94。根据探索性因素分析，得到了七个因素，可以解释总方差的 70.283%。验证性因素分析显示，该量表具有良好或可接受的拟合优度指数。信度分析表明，该量表具有较高的内部一致性和时间稳定性，Cronbach's α、分半系数和重测值分别为 0.926、0.878 和 0.835。
BPHP 量表符合可靠性和有效性的心理测量标准，有望成为围手术期 IPH 管理的有用质量衡量标准。应进一步研究教育或资源需求，制定最佳围手术期低体温预防方案，缩小研究证据与临床实践之间的差距。
