Second, we did not find evidence for significant cross-lagged effects between the MTI Detachment and Antisocial psychopathy factors over time, only strong concurrent factor correlations. In other words, males who reported being emotionally detached from others also endorsed more overt antisocial behaviors, whether assessed at age 17 or age 23. However, there was no evidence that one of these psychopathic domains (e.g., emotional detachment) temporally predicted the other domain (overt antisociality). This pattern of findings may not be surprising given that past research has shown that models depicting causal relations between ostensibly distinct features of psychopathy can be accounted for by models demonstrating that such features are correlated manifestations of a common personality disturbance (Neumann, Vitacco, Hare, & Wupperman, 2005). On the other hand, prospective work by Frick et al. (2003) found that antisocial tendencies predicted the emergence of other psychopathic features (e.g., narcissism) over a 4-year period in non-referred youth from third to seventh grade. The apparent discrepancy of these findings with the present data is potentially explainable by the age differences across the samples such that temporal associations
