[摘要] 目的 確定斜視兒童生存質量量表(Child-IXTQ)在斜視兒童術前生存質量評估中的適宜臨界值。 方法 對106例斜視兒童術前進行Child-IXTQ和兒童生存質量量表(PedsQL4.0)的測評,并以PedsQL4.0作為測評Child-IXTQ的效標,通過對Child-IXTQ各分值對應的靈敏度,特異度計算繪制受試者工作特征曲線(ROC曲線)得出Child-IXTQ在斜視兒童術前生存質量狀況評估中的應用,從而確定最佳臨界值。 結果 Child-IXTQ的得分與兒童生存質量量表PedsQL4.0表得分呈正相關(r = 0.609,P < 0.01);當Child-IXTQ臨界值為67分時,受試者工作特征(ROC)曲線在左上方離標準參照線最遠,此時靈敏度、特異度分別為0.929和0.893,ROC曲線下面積為0.902(P < 0.01),標準誤差為0.052。 結論 Child-IXTQ在斜視兒童術前生存質量評估中的最佳臨界值是67分,是斜視兒童術前生存質量測評的有效工具。

[Abstract] 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 evaluating 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 PedsQL4.0 (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 standard 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 strabismus children.

斜視是兒童易患的眼部疾病之一。它是指一種視軸分離狀態(tài),即兩眼注視同一目標時,一眼注視目標,另一眼偏離目標[1]。據(jù)統(tǒng)計,我國兒童斜視發(fā)病率為3%~4%[2],呈逐年上升趨勢。斜視不僅會引起患兒個人形象紊亂和立體視覺障礙,還會導致患兒心理上出現(xiàn)抑郁、孤獨、低自尊等性格缺陷。他們在學校受到無情的譏諷和嘲笑,在選擇玩伴時遭到排斥,從而造成其生存質量明顯下降[3-5]。斜視兒童生存質量量表(Child-IXTQ)是由美國研究者Hatt等人開發(fā),廣泛應用于斜視兒童生存質量的研究[6-7]。但Child-IXTQ尚未界定臨界值,這將不利于斜視兒童生存質量現(xiàn)狀的了解和干預效果的評價。鑒于同一種疾病不同階段所得問卷的最佳臨界值各不相同的特點,本研究以術前時段為觀測點,旨在探索Child-IXTQ在我國斜視兒童術前生存質量狀況評價的最佳臨界值。
