目的：分析中文版PRE‐DELIRIC谵妄预测模型在ICU患者中的信度和效度。方法选取306例ICU患者作为样本，使用PRE‐DELIRIC谵妄预测模型对其施测以行评价者间信度分析和预测效度分析。结果使用PRE‐DELIRIC谵妄预测模型时，评价者间的信度为0．94（P＜0．01）；预测效度结果表明，当PRE‐DELIRIC谵妄预测模型的阈值取42％时，灵敏度为0．848，特异度为0．946，ROC曲线下面积为0．936（95％ CI：0．910～0．963）（P＜0．001）说明工具具有较好的预测效度。结论 PRE‐DELIRIC的评价者间信度和预测效度较好，适合对ICU患者进行谵妄发生的预测。%Objective To analyze the reliability and validity of Chinese version of PRE‐DELIRIC delirium predic‐tion model for ICU patients .Method 306 patients in ICU was selected for the study .The reliability and predictive validity analysis and evaluation was conducted by using PRE‐DELIRIC delirium predictive models .Result Using the PRE‐DELIRIC delirium prediction model ,the inter‐rater reliability was 0 .94 (P<0 .01) .The predictive validity re‐sults show that when the threshold values of PRE‐DELIRIC delirium prediction model was 42% ,the sensitivity was 0 .848 ,the specificity was 0 .946 ,the area under the ROC curve was 0 .936(95% CI:0 .910~0 .963)(P<0 .001) .It's showed that the tool has good predictive validity .Conclusion The PRE‐DELIRIC between evaluators has good relia‐bility and predictive validity .It's suitable for predicted delirium occurred for ICU patients .
