Were Wolfgangʹs chronic offenders psychopaths? On the convergent validity between psychopathy and career criminality

Both the criminal career and psychopathy literatures have empirically shown that approximately 5 percent of the criminal population accounts for the preponderance of the incidence of crime; however, these areas of inquiry are largely independent. The current study sought to integrate these literatures using a state population of incarcerated delinquents (n = 723). Descriptive, regression, and ROC-AUC analyses produced significant evidence of the effects of personality and affective psychopathic traits on career criminality net the effects of demographic and mental health controls. Psychopathic traits nearly doubled the total explanatory power of the regression model for career criminality and correctly predicted career criminal membership with accuracies ranging from 70 to 88 percent. Implications of these findings and suggestions for increased integration of criminal career and psychopathy research are proffered.
