Examined parent's ability to accurately report their child's cognitive-func
tioning. Participants were 145 children and their parents referred to an ou
tpatient mental health clinic for cognitive testing. Parent reports were me
asured using Likert ratings designed for research and clinical purposes. Ch
ildren's cognitive abilities were measured using the Woodcock-Johnson Psych
o-Educational Battery-Revised (Woodcock, 1989) and the Wechsler Intelligenc
e Scale for Children-Third Edition (Wechsler, 1991). For boys, parental rep
orts of general cognitive ability, fluid reasoning, comprehension-knowledge
visual processing, auditory processing and acquisition and retrieval were
significantly related to performance-based measurements of these same trait
s, and parental report of boys' fluid reasoning and visual processing abili
ty evidenced specificity. For girls, parental report of general cognitive a
bility, fluid reasoning visual processing, and auditory processing were sig
nificantly related to performance-based measurements of these same traits,
and parental reports of girls visual processing and auditory processing evi
denced specificity. These findings suggest areas where clinicians can be mo
ve confident of parental report of children's cognitive abilities and other
areas where clinicians should be wary of parental report.
