^aAge of children, sex and SRS total score were taken as predictive variables, and CSHQ total score was taken as independent variable.

^bAge of children, sex and SRS total score were taken as predictive variables, all CSHQ subscales were included in the regression equation.

Internalizing problems, externalizing problems, and total problems are three important overall subscales of the CBCL.
