Empirical studies of the structure of personality and psychopathology have demonstrated the importance of hierarchical modeling for extending our understanding of relations among mental disorders, as well as between and among abnormal personality traits and dimensions of psychopathology. The current study aims to contribute to this work by examining the joint structure of well-known measures of 'Axis I' psychopathology, the MMPI-2 (Butcher et al., 2001) Restructured-Clinical (RC) Scales (Tellegen et al., 2003), and 'Axis II' personality pathology, the Schedule for Nonadaptive and Adaptive Personality (SNAP; Clark, 1993; Clark, Simms, Wu, & Casillas, in press) using a series of 'top-down' factor analyses, termed the 'bass-ackwards approach' (Goldberg, 2006). The proposed study is a partial replication of Simms, Casillas, Clark, Watson, & Doebbeling (2005), but expands upon this work through the use of structural analysis and an expanded clinical sample (N = 419).
