精神科保护性约束评估量表的编制及信效度检验

Development of psychiatric assessment scale of protective constraint and its reliability and validity test

目的:编制精神科保护性约束评估量表,并评估其信度与效度,为精神科病房保护性约束的使用提供参考依据。方法:通过访谈法,结合文献资料建立保护性约束评估量表的基本框架及发展条目池;经专家咨询及预试验,形成量表。对234名精神疾病患者进行样本测试,评价量表的信度、效度。结果:最终形成了"攻击、自杀、自残、外走、跌倒、坠床"等9个评估指标和27个评估条目。量表总Cronbach’α系数为0.856,各维度的Cronbach’α系数为0.726~0.938;问卷各条目I-CVI的范围为0.80~1.00,S-CVI为0.98;评定者间信度为0.987。结论:精神科保护性约束评估量表具有较好的信度与效度,作为精神科护士实施保护性约束的测评工具,具有重要的临床应用价值。
