Editorial: Conduct Disorder and Its 70-Year History: Lessons From Hervey Cleckley and Lee Robins.

If Cleckley1,2 and Robins3 were alive today, it is conceivable that they may argue about whether conduct disorder (CD) should be measured primarily with personality traits or behavioral characteristics. However, these strict demarcations may not be needed, or most helpful, for understanding youth with conduct problems. Recently, I proposed that CD might be best specified with 3 personality dimensions including grandiose-manipulative (GM), callous-unemotional (CU), and daring-impulsive (DI) traits.4 These traits are observable from an early age, appear to have a genetic basis, and have distinct correlates suggesting potentially differing etiologies relevant to understanding CD. Importantly, each domain is also related to conduct problems and delinquency.5.
