ABCN ABCN Neuropsychological Testing and Measurement

Question 1

Which statistical concept describes the consistency of a neuropsychological test when administered multiple times to the same individual?

Accepted Answer

Test-retest reliability

Answer

Test-retest reliability measures how consistently a test produces the same results across repeated administrations.

Question 2

What does a T-score of 40 on a standard neuropsychological measure indicate relative to the normative population?

Accepted Answer

One standard deviation below the mean

Answer

T-scores have a mean of 50 and SD of 10, so a T-score of 40 is exactly one standard deviation below the normative mean.

Question 3

Which of the following best describes the 'floor effect' in neuropsychological testing?

Accepted Answer

A test lacks sufficient easy items to differentiate among low-functioning individuals

Answer

A floor effect occurs when a test is too difficult for the population, causing scores to cluster at the lowest possible range with little differentiation.

Question 4

The Reliable Change Index (RCI) is used in ABCN practice primarily to:

Accepted Answer

Determine if change between two test administrations exceeds measurement error

Answer

The RCI provides a statistical criterion for determining whether observed score changes reflect true change rather than measurement error or chance variation.

Question 5

Which validity scale on the MMPI-2 is specifically designed to detect random or inconsistent responding?

Accepted Answer

VRIN

Answer

The Variable Response Inconsistency (VRIN) scale detects random responding by identifying pairs of items with similar content answered inconsistently.
