Abstract
ObjectiveTo compare the difference between C-WISC and WISC-Ⅳ in the diagnosis of IQ in the children diagnosed with mental retardation(MR) or borderline intellectual funcition(BIF).
Methods80 children aged 6-16 years were enrolled in this study. All of them were diagnosed with MR or BIF based on the criteria of DSM-Ⅳ-R. Then, C-WISC and WISC-Ⅳ were used to measure the IQ.
ResultsThere was no significant difference in the scores of full IQ between C-WISC and WISC-Ⅳ in these children ((65.49±12.83) vs (64.86±10.10), t=-0.591, P>0.05). The score of verbal intelligence quotient in the C-WISC was significantly lower than the corresponding score in the WISC-Ⅳ ((64.96±13.14) vs (68.26±10.99), t=3.029, P<0.05). The score of performance intelligence quotient in the C-WISC was significantly higher than the corresponding score in the WISC-Ⅳ ((72.48±14.04) vs (69.35±11.75), t=-2.488, P<0.05). The scores of similarities, coding, and block design in the C-WISC were significantly higher than the corresponding score in the WISC-Ⅳ (P<0.05)). There was no significant difference in the scores of comprehension and digit span between the two methods (P>0.05). There was also no significant difference in MR hierarchical diagnosis between the two methods (χ2=0.427, P>0.05).
ConclusionThere is no significant difference between C-WISC and WISC-Ⅳ in the diagnosis of IQ in the children aged 6-16 years who were diagnosed with MR or BIF. Both C-WISC and WISC-Ⅳ can be used to diagnose the MR and marginal intelligence for the children aged 6-16 years.
