Development and psychometric testing of ICU Nurses'Cognition of Acute Skin Failure Questionnaire

目的编制ICU护士对急性皮肤衰竭认知现状问卷并检验其信效度。方法以知信行理论为框架,采用文献回顾法、专家函询法,初步形成ICU护士对急性皮肤衰竭认知现状问卷,通过预调查对问卷进行调整和修改。于2022年7月—8月便利选取浙江省4所三级甲等医院的254名ICU护士作为调查对象,评价问卷的信效度。结果ICU护士对急性皮肤衰竭认知现状问卷包括3个维度,共33个条目。总问卷的内容效度指数为0.848,各条目的内容效度指数为0.889~1.000。探索性因子分析提取3个公因子,累计方差贡献率为73.290%。总问卷的Cronbach'sα系数为0.941,重测信度为0.956。结论ICU护士对急性皮肤衰竭认知现状问卷具有良好的信效度,可作为评估ICU护士对急性皮肤衰竭认知水平的调查工具。
