Objective: The present
study compared results on the Wechsler Adult Intelligence Scale-Revised
(WAIS-R) among adult patients with attention-deficit/hyperactivity disorder
(AD/HD) and those with Asperger’s disorder (AD). Method: WAIS-R results were compared
between 16 adults with AD/HD (8 men and 8 women; mean age, 33.81 years; mean
full-scale IQ, 101.5) and 15 adults with AD (12 men and 3 women; mean age,
30.93 years; mean full-scale IQ, 104.6). Results: Verbal IQ was significantly
higher than performance IQ in the AD group. Among various subtests, scores
were the highest for similarities in the AD/HD group and for block design in
the AD group. Picture completion test scores were the lowest scores obtained in
both groups. A comparison of subtest scores between the AD/HD and AD groups
showed scores for information to be significantly higher in the AD group than
in the AD/HD group. Conclusions: Our results suggest that there are no
differences in verbal IQ, performance IQ, and full-scale IQ scores (except for
scores on the information subtest) among adult patients with AD/HD compared
with adult patients with AD.
