Truth Beyond Measure: Examining the Content Validity of the Hexaco-PI-R Honesty-Humility Scale and the Truthful Communication Scale

We examined the content validity of the widely-used HEXACO-PI-R Honesty-Humility scale (HHS) and the new Truthful Communication Scale (TCS) as reflecting “truthfulness.” Participants judged HHS items as reflecting: a) other constructs *more* robustly than truthfulness, b) truthfulness *less* clearly than TCS items. The TCS appears more content-valid as reflecting truthfulness.
