中文摘要:

背景当前，我国关于精神科护士使用保护性约束知信行的测量工具未充分考虑精神科专科特点，且测评条目繁冗，不利于推广应用，亟需更为科学的测量工具对精神科护士使用保护性约束的知信行水平进行评定。目的构建精神科护士使用保护性约束的知信行量表，并验证其信效度，为评估精神科护士使用保护性约束的知信行水平提供工具。方法基于知信行理论，通过查阅文献、访谈以及德尔菲法形成初版量表。采用分层抽样法，于2021年7月—12月，选取广东省内三级、二级和一级（含未评定等级和基层医院）各2家、共729名精神科护士为研究对象。通过项目分析、探索性因子分析、验证性因子分析形成正式量表，并采用内容效度、结构效度评价量表的效度，采用Cronbach’s α系数、重测信度、折半信度评价量表的信度。结果精神科护士使用保护性约束的知信行量表共12个条目，分为知识、信念、行为三个维度。量表水平的内容效度指数（S-CVI）为0.941，各条目的内容效度指数（I-CVI）为0.812~1.000。探索性因子分析共提取3个公因子，累计方差贡献率为62.948%。验证性因子分析结果显示模型拟合良好。量表的Cronbach’s α系数为0.887，其中知识、信念和行为维度的Cronbach’s α系数分别为0.819、0.842和0.831，量表的折半信度为0.712，重测信度为0.922。结论精神科护士使用保护性约束的知信行量表具有良好的信效度，可用于临床工作中对护理人员保护性约束知识、态度及行为的测评。

英文摘要:

Background The existing tools in China for assessing psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint do not sufficiently consider the specialty in psychiatric practice， and the scale items are somewhat cumbersome to use， which together restrict their further promotion and application. Accordingly， there is an urgent need for developing a more scientific assessment tool.Objective To construct a scale for assessing psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint and to verify its reliability and validity， so as to provide a generic tool for the assessment.Methods Based on the theoretical framework of the knowledge-attitude-practice model， the preliminary scale was formed through systematic literature review， qualitative interview and Delphi method. From July to December 2021， a stratified sampling was utilized to select 729 psychiatric nurses from tertiary， secondary and primary （including unclassified medical institutions and grassroots hospitals） psychiatric hospitals in Guangdong Province. The formal scale was developed through item analysis， exploratory factor analysis and confirmatory factor analysis. The validity of the scale was evaluated by content validity and structure validity， and the reliability was verified by procedures including Cronbach's α coefficient， test-retest reliability， and split-half reliability.Results A total of 12 items of three dimensions （knowledge， attitude， practice） were included in the scale for assessing psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint. The scale-level content validity index （S-CVI） was 0.941， and the item-level content validity index （I-CVI） ranged from 0.812 to 1.000. Exploratory factor analysis extracted three common factors， and the cumulative variance contribution rate was 62.948%. The confirmatory factor yielded adequate fit. Cronbach's α coefficient was found to be 0.887 for the scale， 0.819 for knowledge dimension， 0.842 for attitude dimension， and 0.831 for practice dimension. The split-half reliability and test-retest reliability for the scale were 0.712 and 0.922， respectively.Conclusion The scale shows satisfactory reliability and validity， which can be used to assess psychiatric nurses' knowledge， attitude and practice towards the use of protective restraint. ［Funded by Guangdong Clinical Teaching Base Teaching Reform Research Project （number， 2021JD119）］
