This study has examined relationships between the full set of DSM-IV PDs and the externalizing-internalizing structure of common mental disorders. The factor structure for common mental disorders was comparable to those reported in the literature (Kendler et al., 2003; Krueger et al., 1998, 2005). However, the present study supported the externalizing-internalizing structure as three distinct dimensions, as did Beesdo-Baum and colleagues (2009).
