摘要
目的评价中文版护理谵妄筛查量表(Nursing Delirium Screening Scale Simplified Chinese Version,Nu-DESC-SCV)在慢性酒精中毒患者中的信度和效度。方法选取200例符合中国精神障碍分类与诊断标准第3版的酒精所致精神障碍患者为研究对象,进行Nu-DESC-SCV评定,计算组内相关系数(ICC)评价评定者间一致性;计算克朗巴赫α系数(Cronbach’sα系数)和分半信度评价量表内部一致性;通过与DSM-Ⅳ对照来评价量表的效标效度。结果 Nu-DESC-SCV评定者一致性ICC为0.88,克朗巴赫α系数为0.96,分半信度为0.89。与金标准DSM-Ⅳ对照,应用3分作为分界值时,灵敏度为85.71%,特异度为94.94%,ROC曲线下面积(area under curve,AUC)为0.96,假阴性率为14.29%,假阳性率为5.06%,正确诊断指数为0.8065,阳性预测值为0.8182,阴性预测值为0.9615,阳性似然比为16.9286,阴性似然比为0.1505,诊断符合率为93%,两者的临床诊断一致性Kappa值为0.7927(P<0.01)。结论 Nu-DESC-SCV在慢性酒精中毒患者中具有较好的信度和效度,可作为慢性酒精中毒患者戒酒性谵妄的筛查工具。
Objective To evaluate the reliability and validity of the Chinese version of Nursing Delirium Screening Scale（Nu-DESC-SCV） in chronic alcoholism patients. Methods Totally 200 patients diagnosed as mental disorders due to use of alcohol according to the criteria of CCMD-3 were evaluated with Nu-DESC- SCV. Intraclass correlation coefficient（ICC）analysis was applied to examine interrater consistency. Crobach＇s α coefficient and split-half reliability was applied to examine internal consistency. Criterion validity was evaluated by comparing with DSM-IV . Results ICC value was 0.88,Crobach＇s a coefficient was 0.96, the splithalf reliability was 0.89. When the cut-off point of Nu-DESC-SCV was determined as ≥ 3, the sensitivity of Nu-DESC-SCV was 85.71%,the specificity was 94.94%, the area under curve（AUC）was 0.96, the false positive rate was 14.29%, the false negative rate was 5.06 %, the Youden＇s index was 0. 8065, the positive predictive value was 0. 8182, the negative predictive value was 0. 9615, the positive likelihood ratio was 16. 9286, the negative likelihood ratio was 0. 1505. The diagnose accordance rate was 93% and the overall cross-validated Kappa was 0. 7927（P〈0.01）. Conclusion Nu-DESC-SCV has good reliability and validity, therefore it may be used as a clinical instrument to evaluate the withdrawal state with delirium in chronic alcoholism patients.
