What approach does Griffin Hill use to assess reliability in integrity testing?

• A. To rely solely on consistency checks across items.
• B. To rely solely on behavioral indicators.
• C. To combine consistency checks across items and behavioral indicators to differentiate stable integrity patterns from randomness.
• D. To compare scores to industry benchmarks.

Answer: (C)

Reliability in integrity testing comes from showing that scores reflect a stable pattern, not random noise. Griffin Hill combines two sources of evidence: internal consistency across items, which shows that the items meant to measure the same trait move together, and behavioral indicators, which capture how responses manifest in real behavior and over time. This twin approach helps separate genuine, stable integrity signals from random variation or faked responses, giving a more dependable picture of a person’s true tendency. Relying only on consistency checks could miss how behavior shifts across contexts, while relying only on behavioral indicators might pick up situational factors rather than a consistent trait. Comparing scores to benchmarks is useful for interpretation, but it doesn’t by itself establish reliability the way combining consistency with behavioral signals does.
