Given the diversity of individuals who undergo psychological assessment, examining whether cultural bias exists in psychological assessment instruments (i.e., differential validity) is crucial.

Regression models were estimated in a multigroup framework. The analyses yielded negligible to small statistical evidence of differential validity in MMPI-2-RF scores predicting the number of future suicidal behaviors and violent behaviors in the samples. This evidence supports use of the MMPI-2-RF as a generally unbiased instrument for predicting key criteria across genders and ethnicities in a forensic psychiatric population. Public Significance Statement This study supports use of the MMPI-2-RF in forensic settings as a generally unbiased instrument for predicting suicidal and violent behaviors across genders (male, female) and ethnicities (Caucasian, African American, and Hispanic/Latino American).
