Validity Scales: Patterns Observed across Veteran Affairs Settings

A study conducted at various Veteran Affairs settings reveals high frequencies of invalidity on MMPI-2 and MMPI-2-RF scales. Over-reporting is the most common pattern, with multiple scales being invalidated in profiles. Findings vary by service location.

  1. Validity Scales: Patterns Observed across Veteran Affairs Settings a. Texas Tech University, b. Eastern Kansas Veteran Healthcare System, c. John Carrol University, d. Kent State University Paul B.Ingramab, Anthony M. Tarescavagec, Yossef S. Ben-Porathd, & Mary E. Oehlertb

  2. Project Background and Context • 7-year national Sample of MMPI-2 and MMPI-2-RF Administrations • All service locations within the VA included (Stop Codes) • Investigation focuses on outpatient services • VA is unique in its evaluative complexity

  3. Invalidity Criteria: CNS ≥ 18, VRIN-r ≥ 80, TRIN ≥ 80, F-r ≥ 120, and Fp-r ≥ 100.

  4. Overall Scale Cumulative Frequencies

  5. Frequency of Multiple Scale Elevations

  6. Invalidity By Stopcode

  7. Conclusions • High frequencies of invalidity observed • Frequency of uninterpretable profiles varies by service location • Over-reporting is most frequent invalidity pattern • Most with one over-reporting elevation have multiple scales invalidated
