Help interpreting WISC IV results


ange78 May 26, 2012

My daughter who is turning 7 has the following WISC IV results:

VCI 95
PRI 131
WMI 113
PSI 100

FSIQ 113

Similarities 11
Vocabulary 11
Comprehension 5
Block Design 13
Picture Concepts 17
Matrix Reasoning 15
Digit Span 14
Letter-Number Sequencing 11
Coding 8
Symbol Search 12

So far we have a diagnosis of ADHD but am wondering if anyone can tell me if these scores stand out for any particular LD.

Achievement tests show her reading accuracy age at 12.5 years, but reading comprehension at 8 years. Spelling she is 9 years old and maths is average for her age.

Thank you

Hi Angela
Your daughter scores look alot like my sons.As I understand it, It is usually a discrepency between IQ and achievement that shows a specific learning disability. So you might want to post your daughters achievement scores. I do want to point one thing out, in case the tester did not tell you. The significant scatter(36 points) between PRI & VCI makes the Full scale indeteminable. So I hope they are not using the 113 as her true ability and then comparing it to the achievement. I am unfamiliar with how ADHD presents in scores but my sons lower verbal scores(VCI 95 PRI 129) was because of a difficulty with language processing and expressive language. He had a history of language delay and now recieves speech. Do you have any concerns with her speech?It also confirmed that my son is a visual spatial learner (loves puzzles,legos, taking things apart) which unfortunately is a learning style that schools do not often teach to. Your daughters scores indicate she is very bright and her ability is probably much higher than her full scale shows. I guess what I would ask myself if I were you is how does her IQ/Achievement scores line up with her classroom performance? Also do you think her ADHD influenced the VCI? Maybe ask the school to do more indepth language testing. I also recieved invaluable information at the millermom proboard site. A lot of the parents there have children with ADHD/other learning differences and could probably help you tease out those scores and give you direction. I wish I could give you more info but I am new to this as well and my son is very much a little puzzle :) I wish you and your daughter the best!

Hi Angela,

There are many things that need to be taken into account when looking for a LD besides just the cognitive assessment. When looking at learning disabilities, one looks at the areas of academic achievement, as well as, the basic psychological processing domains. The biggest thing that jumps out from your daughter's scores is the low Comprehension score which falls significantly below that of her other scores. This could be a fluke but I would suggest having that area looked at further. If you have not already had an evaluation by a speech-language pathologist done I would look into having one done to evaluate her language processing and comprehension skills. How is your daughter's ability to solve a problem in more than one way and social skills? If children have difficulty in either of these areas they can score lower on this subtest. Questions are posed to them asking them things like "if you found a wallet in a store what would you do?" If the child can come up with two different ways to solve the problem then they receive two points, if they only come up with one then they only receive one point. Difficulties in either flexible thinking or social skills can also negatively impact the comprehension subtest score. The rest of her scores look like she has good short-term, working memory memory, and visual processing skills. She is obviously a very smart young lady. Good luck!

Hi Angela,

I can't help you interpret the testing result, but maybe my story can help you...

I wasn't diagnosed with "ADHD" until I was 28. I thought the ADHD medications would help and explain my difficulties at work. Then few months after my 29th birthday, I paid for a full assessment to see if I had any learning disabilities. Since I was an adult, the psychologist used the WAIS-IV test. The assessment confirmed that I had a Reading Disorder. Due to low performance in certain testing, the psychologist suspected I might have Central Auditory Processing Disorder (CAPD). It took me another year before I went to an audiologist that specialized in CAPD testing. I was surprised by the results. In addition to CAPD, I also had hyperacusis (sensitivity to sound). Now, I wear a specialized hearing aid to help treat my hyperacusis and also help me hear more clearly.

Looking back... some of my "ADHD" symptoms were likely caused by my learning and hearing disabilities. The ADHD medications helped, but didn't address the real problem. My psychiatrist told me about the Arrowsmith Program that deals with various learning disabilities.

If the standardized psycho-educational testing or ADHD medications didn't help much, maybe you can look into the Arrowsmith program...

here are some links...

The split between your daughter's PRI and VCI is interesting and also unusual. That your daughter got such a high score on the PRI shows that she's very bright. Only very bright children can get that kind of a score on the Perceptual Reasoning Index. I would think her Full Score IQ is actually higher than 113 but her ADHD is pulling her Verbal Comprehension Index score down.

That her reading comprehension is 4 grade levels below her reading accuracy is something I'd focus on. Read aloud to her every night if you can - talk with her about the reading. Give her simpler books to read on her own to see if we can help her comprehension catch up to her reading accuracy. She might have some learning difference. I'd want to ask questions like - how old was she when she began to talk? How are her verbal skills?

The truth is - your daughter is only 7 and her reading accuracy is at a 12.5 years level - that's impressive. I would give her time - her skills may all come together. In the meantime, read aloud to her every day if you possibly can. A wealth of studies show that reading aloud to a child improves their own reading comprehension.

Hello Angela. the first thing it is to forgive my english. not native and live far from the USA.
but as a psycologist I can , maybe, help you in this case.
Your daughter has an excellent IQ,
the difference between subtests verbal y performance tests are amazing.
I saw she has a low performance in comprehension and coding.
the first one could indicate an overprotected child, without independence in their opinions. and the second one indicate a low present hability to retain and memorize visuals signals. this one we can find in TDHA but it is not concluent.
If she performs low in verbal tests, it is time to stimulate her at home reading yourself to her and asking what you have read.
and I suggest, a visit to a doctor oftalmologist to check out her visual capacity.
In a year you will be ready to made another testing session and comments the results.
