Relationship between the Chinese Version Weehsler intelligence scale for children and the Das-Naglieri cognitive assessment system in children with attention deficit hyperactivity disorder

Abstract

Objective To explore the relationship between the Chinese Version Wechsler intelligence scale for children(C-WISC) and the Das-Naglieri cognitive assessment system(DN: CAS) in children with attention deficit hyperactivity disorder (ADHD). Methods Thirty-two children with ADHD were evaluated with C-WISC and the digital remote assessment system——DN: CAS, and both results were administered for correlation analysis. Results The results showed that there was a strong correlation between the full intelligence quotient (FIQ) of C-WISC and the full score of DN: CAS, also the scores in Plan, Simultaneous, and Successive of DN-CAS, and the correlation coefficient was between 0.6 to 0.8. There was a strong correlation between the full score of DN: CAS and the verbal comprehension IQ(VCIQ), perceptual organization IQ(POIQ), memory/concentration IQ(M/CIQ), verbal IQ(VIQ), and performance IQ(PIQ) of C-WISC, as the correlation coefficient ranges from 0.6 to 0.8. There was also a strong correlation between the score in Planning and VCIQ, POIQ, M/CIQ, VIQ of C-WISC. As to the score in Simultaneous of DN: CAS and POIQ, VIQ, PIQ of C-WISC, the correlation was also strong with the correlation coefficient ranging from 0.6 to 0.8. For the rest of the sub-tests of C-WISC and DN: CAS, there was moderate correlation between them, the correlation coefficient was from 0.4 to 0.6. Conclusions These results show that the correlation between C-WISC and DN: CAS in children with ADHD is significant. The correlation coefficient shows diversity in the sub-tests of C-WISC and DN: CAS.
