Results In Chinese version all the original 18 items were kept and four factors were extracted:externalizing,attention problems,parenting challenges and internalizing,which were accumulated as 49.66% of the total variance.Factor loadings of items were 0.35~0.81.The Cronbach's α coefficient was 0.83.The test-retest reliability was 0.53(P<0.01).ROC analysis yielded a sensitivity of 71.6% at a specificity of 70.6% when the cutting score was 12 for boys and a sensitivity of 67.3% at a specificity of 65.5% when the cutting score was 10 for girls.
