With the current study, we examined parental fitness litigant response patterns on the MCMI-IV and assessed the presence of a .

Results of the current study suggest a new elevations on the Desirability (Y), Histrionic (4A), Turbulent (4B), and Compulsive (7) scales. The clinical implications for the use of the MCMI-IV by forensic psychologists with parental fitness litigants are discussed including limitations and areas for future research.
