Does PIQ significantly > PIQ always NLD?

Post Reply New Topic

My last IQ test showed a difference of more than 40 pts.

No, not always. A large VIQ-PIQ gap doesn't always indicate impairment/disorder. In fact, the more extreme your IQ (either high or low), the more likely that there will be a significant VIQ-PIQ gap (there are actually tables of percentages to work out the likelihood of different size gaps at different IQs). That said, if you have a large VIQ/PIQ gap, and your history suggests NLD, it is worth investigating (as I know you are- good luck! ) . But a large gap on its own is not enough for diagnosis.

oops that should read VIQ>PIQ. typed it fast. thanks for the response. yeah me and the psch have been playing phone tag. finally got back to me this week and called once after that I wasn't there. hopefully I'll speak to him next week.
