Tests of Integrity, HEXACO Personality, and General Mental Ability, as Predictors of Integrity Ratings in the Royal Dutch Military Police

In a Dutch military trainee sample, we investigated the validity of overt and personality-based integrity tests, HEXACO personality dimensions, and general mental ability (GMA), for predicting self (N = 336) and supervisor (N = 175) ratings of behavioral integrity. Both self and supervisor ratings were predicted by integrity and personality tests, but not by GMA. Incremental validity was partially observed for specific tests of integrity and personality. Findings contribute to various underresearched areas in the domain of integrity testing, as they show evidence of validity (1) for predicting a rarely observed criterion (ratings of behavioral integrity) (2) beyond two alternative types of predictors in personnel selection (3) in a military setting (4) outside North America
