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.
