The purpose of the current study was to test empirically the convergent and discriminant validity of 3 recently developed, alternative measures of maladaptive personality traits: the Personality Inventory for Diagnostic and Statistical Manual for Mental Disorders-Fifth Edition (DSM-5, PID-5; Krueger, Derringer, Markon, Watson, & Skodol, 2012), the Computerized Adaptive Test-Personality Disorder Static Form (CAT-PD-SF; Simms et al., 2011), and Five Factor Model Personality Disorder scales (FFMPD; Widiger, Lynam, Miller, & Oltmanns, 2012). These measures were constructed with different rationales and methods, yet the result was highly congruent. The PID-5 and CAT-PD-SF were administered to 286 community adults with current or a history of mental health treatment; the CAT-PD-SF and FFMPD scales to 262 such adults; and the PID-5 and FFMPD scales to 266. The results indicated good to excellent internal consistency, as well as good to excellent convergent and discriminant validity for most scales with a few notable exceptions. Suggestions for future research are provided, including the potential benefits of scales that are unique to a respective instrument, replication of a dependency factor, and exploration as to the basis for instances of questionable convergent or discriminant validity.
