【摘要】：目的检验骨质疏松知识评价工具(OKAT)在中国老年住院患者中应用的信效度。方法将英文版骨质疏松(OP)知识评价工具OKAT翻译成中文版,采用方便取样的方法在济宁医学院附属医院对300例老年住院患者进行问卷调查。采用SPSS17.0和AMOS17.0软件进行信效度分析,采用内部一致性Cronbachα系数、分半信度系数、组内相关系数、条目-总分相关系数等评价信度;采用探索性因子分析(EFA)和验证性因子分析(CFA)评价其效度。结果 Cronbachα系数为0.811,分半信度系数0.901,各条目组内相关系数(ICC)0.236~0.532,条目相关性分析显示各条目得分与总分均具有显著相关性。经EFA得到两个因子,各条目的共同度为0.621~0.851,累计解释方差68.532%。对模型进行CFA得到调整拟合优度指数(AGFI)0.922、拟合优度指数(GFI)0.946、近似误差平方根(RMSEA)0.003、回归系数0.16~0.88。此评价工具的最佳临界点为9分,≥9分时表示有OP的危险,其灵敏度73.6%、特异度为60.6%,其受试者工作曲线(ROC)下面积为0.755。结论中文版OKAT在老年住院患者中应用信效度良好,可为筛查老年住院患者OP提供参考依据。
[Abstract]:Objective to test the reliability and validity of osteoporosis knowledge evaluation tool (OKAT) in elderly inpatients in China. Methods the English version of osteoporosis (OP) knowledge evaluation tool OKAT was translated into Chinese version. A questionnaire survey was conducted on 300 elderly inpatients in Jining Medical College affiliated Hospital by convenient sampling method. Reliability and validity were analyzed by SPSS17.0 and AMOS17.0 software. The reliability was evaluated by internal consistency Cronbach 伪 coefficient, split-half reliability coefficient, intra-group correlation coefficient, item-total score correlation coefficient and so on. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to evaluate its validity. Results the Cronbach 伪 coefficient was 0.811, the split-half reliability coefficient was 0.901, and the (ICC) correlation coefficient was 0.2360.532.The item correlation analysis showed that each item score had significant correlation with the total score. Two factors were obtained by EFA. The common degree of each item was 0.621 / 0.851.The cumulative explanatory variance was 68.532. CFA was used to obtain the adjusted goodness of fit index (AGFI) 0.922), the fitting index (GFI) 0.946), the square root of approximate error (RMSEA) 0.003), and the regression coefficient (0.16g / 0.88). The optimal critical point of this evaluation tool is 9 points, when 鈮，
