Lie Scales

By Renée Grinnell

A set of items included in a psychological evaluation to indicate whether or not the respondent has been truthful in other parts of the test.

Example: Some lie scales include sets of nearly identical questions to test response consistency (“I never regret the things I say” might appear in the same test as “I’ve never said anything I later wished I could take back”).
