EPPP Assessment and Diagnosis Principles 3

Question 1

A researcher uses a test at one point in time to predict a criterion measured six months later. This is an example of which type of validity?

Accepted Answer

Predictive validity

Answer

Predictive validity assesses how well test scores forecast a future criterion, measured after a time delay.

Question 2

Which approach to clinical assessment relies most heavily on actuarial data and statistical formulas rather than clinical intuition to combine test findings?

Accepted Answer

Mechanical (actuarial) prediction

Answer

Mechanical or actuarial prediction uses empirically derived formulas and base rates to combine data, consistently outperforming clinical prediction in research.

Question 3

On the MMPI-3, which validity scale detects an overly positive self-presentation and denial of common human flaws?

Accepted Answer

L scale

Answer

The L (Lie) scale measures an unsophisticated attempt to present oneself in an unrealistically positive light by denying minor faults.

Question 4
