地震后斯坦福急性应激反应问卷最佳筛查阈值ROC分析
Roc curve analysisia of optimal cutoff value of SASRQ for screening acute stress disorder after earthquake
摘要
Abstract
Objective: To assess acute stress disoder (ASD) symptoms and study the optimal cutoff value of Stanford acute stress reaction questionnaire ( SASRQ) among victims of earthquake in temporary settlements. Methods; Two hundred and twenty-three victims were randomly chosen and measured by SASRQ. Then data were analyzed according to symptom criteria of DSM-IV ASD , and the result of symptomatology analysis was taken as actual state variable of ROC curve and total score of SASRQ as the test variable. The point on ROC curve having the highest Youden Index was considered as the optimal cutoff value. Results: Sixteen cases (7. 2% ) of victims met symptom criteria of DSM-IV ASD among victims. There were 69 cases (30. 9% ) with dissociative symptoms, 98 cases (44. 0% ) with re-experiencing trauma, 70 cases (31. 4% ) with avoidance and 117cases (52. 5% ) with arousal or anxiety. Area under the curve (AUC) of ROC was 0. 907 ±0. 021 (95%CI: 0.865-0.939), P< 0. 01. The point of 40 had the highest Youden Index of 0. 771, and had a sensitivity of 0. 938 and specificity of 0. 773. Conclusion; ASD symptoms are common among victims in temporary settlements still the second week after Wenchuan Earthquake, and 40 may be the optimal cutoff value of SASRQ for screening ASD symptoms.关键词
