摘要
目的确定斜视儿童生存质量量表(Child-IXTQ)在斜视儿童术前生存质量评估中的适宜临界值。方法对106例斜视儿童术前进行Child-IXTQ和儿童生存质量量表(PedsQL4.0)的测评,并以PedsQL4.0作为测评ChildIXTQ的效标,通过对Child-IXTQ各分值对应的灵敏度,特异度计算绘制受试者工作特征曲线(ROC曲线)得出Child-IXTQ在斜视儿童术前生存质量状况评估中的应用,从而确定最佳临界值。结果 Child-IXTQ的得分与儿童生存质量量表PedsQL4.0表得分呈正相关(r=0.609,P<0.01);当Child-IXTQ临界值为67分时,受试者工作特征(ROC)曲线在左上方离标准参照线最远,此时灵敏度、特异度分别为0.929和0.893,ROC曲线下面积为0.902(P<0.01),标准误差为0.052。结论 Child-IXTQ在斜视儿童术前生存质量评估中的最佳临界值是67分,是斜视儿童术前生存质量测评的有效工具。
Objective To identify the optimal critical value of the child intermittent exotropia questionnaire (Child-IXTQ) in preoperative quality of life assessment for strabismus children. Methods A prospective cohort of 106 strabismus children were recruited to complete the Child-IXTQ and PedsQL4.0 questionnaire, and the PedsQL4.0 was used as the criterion for evaluating Child-IXTQ. Through the sensitivity and specificity calculation of each score corresponding to Child-IXTQ, we draw the receiver working characteristic curve (ROC curve) to get the application of Child-IXTQ in e- valuating the quality of life of strabismus children before operation so as to determine the best critical value. Results The score of Child - IXTQ was positively correlated with the score of PedsQL7.0 (r = 0.609, P 〈 0.01). The optimal critical value for Child-IXTQ was 67 scores, the subject's operating characteristic (ROC) curves is the farthest from the stan- dard reference line in the upper left. The sensitivity and specificity were 0.929 and 0.893 respectively, the areas under the curve was 0.902 (P 〈 0.01), and the standard error was 0.052. Conclusion The optimal critical value of Child-IXTQ for the strabismus children is 67 scores, and it is an effective tool for preoperative assessment for quality of life of stra- bismus children.
