In this study, we examined the relationship between parental history of psychopathology and latent dimensions of offspring psychopathology (new onsets following 9/11) in a representative sample of Americans. Consistent with previous studies (Kendler et al., 1997), we found that parental problems with alcohol, drug, antisocial behavior, and depression were related to both INT and EXT. Consistent with prior expectations, parental alcohol, drug, and antisocial behavior problems were more closely related to EXT, while parental depression was more closely related to INT. In addition, we found associations between childhood maltreatment and initial onset of dimensions of psychopathology after 9/11.
