摘　　要：目的设计国内患者适用的压疮危险因素评估表(下称评估表),并检验其信效度。方法分析国外压疮评估表的弊端,结合国内研究和临床实践,设计出包括神志、意识状况,营养状况,活动情况,体位变换能力,排泄控制,皮肤感觉,皮肤状况7个方面的评估表,选取5名专家,15例及7 329例住院患者分别进行内容效度(CVI)、信度(Cronbach′sα系数)及临床效度(灵敏度,特异度)检验。结果评估表CVI=0.686,Cronbach′sα=0.891,灵敏度=0.843,特异度=0.729。结论本评估表具有较稳定的信度和较好的效度,可作为医院压疮危险因素的评估工具使用。Objective To develop a pressure ulcer risk assessment scale for Chinese patients, and to examine its reliability and validi- ty. Methods We analyzed shortages of foreign pressure ulcer assessment tools and designed a pressure ulcer risk assessment scale, which included such 7 aspects as consciousness, nutritional status, activity, ability of change of body positions, urination and defe- cation control, skin sensory, and skin status, based on clinical practice and researches in our country. Five experts, 15 and 7 329 inpatients were surveyed to test content validity （CVI）, reliability （coefficient of Cronbach alpha） and clinical validity （sensitivity and specificity）. Results The CVI of the scale was 0. 686 and the coefficient of Cronbach alpha was 0. 891; the sensitivity was 0. 843 and the specificity was 0. 729. Conclusion The new pressure ulcer risk assessment scale has satisfactory reliability and validity, which can be used to predict pressure ulcer risk for hospitalized patients.
