Impulsivity & Hyperactivity

This dimension is split into two groups of questions, "Impulsivity" and "Hyperactivity", and it is the only one of the eight that is worked out differently from the rest. Instead of averaging all the questions together, we average Descriptive range The words a report uses to sum up a score, like 'average' or 'extremely low'. Tests draw these bands in their own places, so the same word can mean different scores. Read the full definition of Descriptive range each of the two groups on its own and then use whichever of the two comes out higher.

That has two consequences worth knowing. A strong pattern in just one of the two groups can set the result for the whole dimension, which is on purpose so that a clear pattern is not watered down by the other group. And the label here is telling you about the stronger of the two patterns, not about both together. Its label therefore means something different from the labels on the other seven dimensions, which are all a single average across everything you answered.

This is also the only dimension whose top cut-off Cut-off A line drawn through a range of scores. On one side a service may offer an assessment or support, on the other side it may not. Read the full definition of Cut-off changes three times as a child grows: it is highest for children under 8, lower from 8 to 11, and lower again from 12.
