目的 进一步探讨自制老年住院患者安全危险因素评估量表的信度与效度.方法 采用自行设计的老年住院患者安全危险因素评估量表,该量表由5个分量表,27个条目构成,选取433例老年住院患者对量表进行测试.结果 各分量表的内部一致性Cronbach'sα信度系数为0.602~0.797,总量表的Cronbach'sα信度系数为0.809,分量表的重测信度Pearson相关系数为0.852~0.955,总量表的Pearson相关系数为0.953.因子分析法中5个公因子累积方差解释率为57.70%,每个条目的因子负荷都在0.4以上.预测效度中各分量表的得分的ROC曲线下面积为0.836~0.981,差异有统计学意义.结论 该量表具有良好的信度与效度,为量表的临床应用与推广提供依据.
