Social communication impairments and restricted, repetitive patterns ("Kodawari") considered from the "Comprehension" section of the WISC-IV in autism spectrum disorder

The objective of the present study was to apply the WISC-IV to clinical assessment of ASD and clarify how the characteristics of the disorder were reflected in specific items. Methods The study participants were 20 patients aged 5-16 years diagnosed with ASD according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). We recruited 20 patients with attention-deficit/hyperactivity disorder (ADHD) and 20 patients with other disorders (neurotic disorders) as controls. We then compared the scores of the ninth item of the WISC-IV ("Comprehension") among the three groups. Results The differences observed between the ASD vs. the other disorders group were not significant by the standard scoring method. Thus, a two-level scoring method of 0 and ≥ 1 point was adopted. As a result, significantly more participants in the ASD group scored 0 points compared with the ADHD and other disorders groups. Discussion The results of the present study revealed that a characteristic of ASD appeared in the ninth item of "Comprehension" on the WISC-IV.
