The hypothesis that the MMPI–2 Psychopathology–5 scales are better predictors of personality disorders than the Revised NEO Personality Inventory scales was tested using Personality Adjective Checklist personality disorder scales with a 9-point response format. The three inventories were completed by 258 introductory psychology students (113 men and 145 women) for partial course credit. Hierarchical multiple regression analysis was performed for predicting each Personality Adjective Checklist scale by entering the Revised NEO Personality Inventory scales as a set in the first step and the Psychopathology–5 scales as a set in the second step. Incremental validity of the Psychopathology–5 scales over the Revised NEO Personality Inventory scales for predicting each Personality Adjective Checklist scale was measured by the R2 change at the end of the second step in the hierarchical multiple regression analysis. Incremental validity values ranged from .01 to .09, with a median of .03, and were significant for only five Personality Adjective Checklist scales. Such results provided very little support for the hypothesis of relative superiority of the Psychopathology–5 scales over the Revised NEO Personality Inventory domain scales for predicting personality disorders.

Preemployment psychological evaluation utilizing personality inventories is common in law enforcement settings. The Revised NEO Personality Inventory (NEO PI-R), developed from the five-factor theory of normal personality functioning, has proven useful in personnel selection. This study examined the predictive validity of NEO PI-R facet scales for predicting academic, firearms, physical, and disciplinary elements of police academy performance, as well as academy graduation. Results indicated that recruits higher in Values and lower in Excitement-Seeking did better academically, those lower in Anxiety did better at firearms, and those lower in Deliberation and Fantasy and higher in Activity did better in physical training. In a logistic regression analysis, Excitement-Seeking, Ideas, and Values predicted disciplinary memos, whereas Self-Consciousness, Altruism, Feelings, Order, Positive Emotions, and Vulnerability predicted absenteeism. Vulnerability to stress was the sole multivariate predictor of graduation. The use of the NEO PI-R as a selection instrument for police officers appears promising.
