Abstract
The present study examined the convergent validity of the Shedler-Westen Assessment Procedure Q-Sort (SWAP-200; Shedler and Westen, 1998; 1999a; 1999b; 2004a) dependency scales (Dependent Personality Disorder [DPD] Clinical Prototype and DPD composite description) by examining links between these variables with Inventory of Interpersonal Problems Circumplex Scales (IIP-C; Alden et al., 1990; Horowitz et al., 2000; Horowitz et al., 1988), and DSM-IV diagnoses of DPD in a clinical sample (N = 85). Results showed that SWAP-200 DPD Clinical Prototype was significantly related to a DSM-IV diagnosis of DPD, higher scores on the IIP-C Affiliative/Submissive Quadrant summary scale, and elevations on Nonassertive and Overly-accommodating Octant Scales. Additional analyses revealed significant positive relationships between the DPD composite description with DSM-IV diagnosis of DPD, the Affiliative/Submissive Quadrant summary scale, and the Overly Accommodating and Self-Sacrificing Octant Scales. We discuss the implications of these findings with regard to theoretical, empirical, and clinical aspects of interpersonal dependency.
