Wechsler Test Score Interpretation and Report Writing 4

Question 1

On the WISC-V, which index reflects fluid reasoning with novel visual problems?

Accepted Answer

Fluid Reasoning Index

Answer

The Fluid Reasoning Index measures the ability to solve novel problems using inductive and quantitative reasoning.

Question 2

A General Ability Index (GAI) is most useful when which factors are notably low?

Accepted Answer

Working Memory and Processing Speed

Answer

The GAI minimizes the influence of working memory and processing speed, useful when those are depressed.

Question 3

If a subtest is spoiled or invalidated during administration, what is the appropriate reporting practice?

Accepted Answer

Substitute a proration or note the omission

Answer

Spoiled subtests should be handled with proration where allowed or clearly noted as not interpretable.

Question 4

What does it mean when two index scores show a statistically significant difference?

Accepted Answer

The difference is unlikely due to measurement error alone

Answer

A statistically significant difference is unlikely to result from measurement error and reflects a real discrepancy.

Question 5

Why is base rate (frequency of occurrence) important when interpreting an index discrepancy?

Accepted Answer

It indicates how common the difference is in the population

Answer

Base rate tells you how unusual a discrepancy is, distinguishing common variation from clinically meaningful patterns.
