【摘要】 [目的]编制脑卒中相关性肺炎护理风险评价问卷,并检验信效度。[方法]以风险管理理论为理论框架,通过文献研究、半结构访谈和德尔菲法,初步拟定脑卒中相关性肺炎护理风险评价问卷。抽取210名三级甲等医院脑卒中专科护士进行问卷调查,通过项目分析、探索性因子分析及相关性分析形成正式问卷并进行信效度检验。另抽取201名三级甲等医院脑卒中专科护士进行问卷调查,通过验证性因子分析,构建结构方程模型。[结果]最终确定包括病人因素、医源性因素、健康行为相关因素、医护人员因素、科室管理因素、辅助系统因素6个维度,共33个条目的脑卒中相关性肺炎护理风险评价问卷。问卷折半信度系数为0.842,总体Cronbach’sα系数为0.940,各维度Cronbach’sα系数为0.708～0.908。问卷全体一致量表内容效度指数(S-CVI/UA)为0.848,量表平均内容效度指数(S-CVI/Ave)为0.988,条目内容效度指数为0.875～1.000。结构效度KMO值为0.915(P<0.001),累积方差贡献率为64.456%,各维度与问卷总分相关系数为0.446～0.893(P<0.01);验证性因子分析拟合总体较理想,卡方自由度比(χ2/df)为1.865,均方根残差(RMSEA)为0.066,比较拟合优度指数(CFI)为0.902,递增拟合指数(IFI)为0.903,规则适配指数(PNFI)为0.711,简约调整适配指数(PCFI)为0.719。[结论]构建的脑卒中相关性肺炎护理风险评价问卷具有一定科学性和合理性,可以作为临床实践的参考依据。更多还原

【Abstract】 Objective:To develop nursing risk assessment questionnaire for stroke associated pneumonia and to test its reliability and validity.Methods:With framework of risk management theory,initial nursing risk assessment questionnaire for stroke associated pneumonia was formed through literature research,semi-structured interview,and Delphi method. Questionnaire survey was conducted among 210 stroke specialist nurses in tertiary A hospitals. Formal questionnaire was formed through item analysis,exploratory factor analysis and correlation analysis. And its reliability and validity were tested. Questionnaire survey was conducted with 201 stroke specialist nurses in tertiary A hospitals. Structural equation model was constructed through confirmatory factor analysis.Results:Finally,nursing risk assessment questionnaire for stroke associated pneumonia consisted of 6 dimensions,involving patient factors,iatrogenic factors,health behavior related factors,medical staff factors,department management factors,and auxiliary system factors. And it contained 33 items. Half reliability coefficient of questionnaire was 0. 842,Cronbach’s a coefficient of total questionnaire was 0. 940,Cronbach’s α coefficient of each dimension was from 0. 708 to 0. 908. Scale-content validity index/universal agreemen(tS-CVI/UA)was0. 848. Scale-content validity index/average(S-CVI/Ave)was 0. 988. And item-level content validity index was from 0. 875 to 1. 000.KMO value of construct validity was 0. 915(P<0. 001). Cumulative variance contribution rate was 64. 456%. And correlation coefficient between each dimension and total score of the questionnaire was from 0. 446 to 0. 893(P<0. 01). In general,confirmatory factor analysis fitted better in. Chi-square degree of freedom ratio(χ2/df)was 1. 865,root mean square residual(RMSEA)was 0. 066,comparative goodness of fit index(CFI)was 0. 902,incremental fit index(IFI)was 0. 903,parsimonious normed fit index(PNFI)was0. 711,and parsimonious comparative fit index(PCFI)was 0. 719.Conclusions:The constructed nursing risk assessment questionnaire for stroke associated pneumonia is scientific and reasonable. It can be used as reference for clinical practice.更多还原
