MMPI Validity Scales Interpretation 3

Question 1

A T-score of 75 on the K scale in a personnel selection evaluation most likely reflects:

Accepted Answer

Sophisticated defensiveness and positive self-presentation

Answer

Elevated K in a high-stakes selection context typically indicates an intelligent test-taker who is strategically minimizing faults and presenting in an unrealistically favorable light.

Question 2

The K scale was originally developed as a correction factor; K-corrected scores add a fraction of raw K to which clinical scales?

Accepted Answer

Scales 1, 4, 7, 8, and 9

Answer

K corrections are applied to Hs (1), Pd (4), Pt (7), Sc (8), and Ma (9) to compensate for defensiveness suppressing these scales.

Question 3

High L scale scores most commonly reflect which personality characteristic in non-clinical populations?

Accepted Answer

Naive or unsophisticated denial of minor faults

Answer

Elevated L indicates the respondent is denying common human flaws (e.g., never being angry), suggesting a naive or moralistic self-presentation rather than sophisticated deception.

Question 4

The S (Superlative Self-Presentation) scale on MMPI-2 was developed specifically to detect over-reporting in which context?

Accepted Answer

Personnel and pre-employment screening

Answer

S was empirically derived from airline pilot applicants who produced the most favorable self-descriptions, making it particularly sensitive to faking-good in personnel contexts.

Question 5

A protocol with L=78T, K=72T, and F=41T in a child custody evaluation is best described as:

Accepted Answer

Reflecting defensive underreporting requiring cautious interpretation

Answer

The 'V-shaped' validity pattern (high L and K, low F) in custody settings signals a defensive response set where the parent minimizes problems to appear favorable to the court.
