Scientists who study psychopathology have long debated whether mental disorders are best characterized as discrete categories or as extreme expressions of continuously distributed personality traits (Meehl, 1995). Although the Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association, 2000) exemplifies the categorical perspective, it is widely recognized that diagnostic syndromes affect people to varying degrees, and that some people exhibit clear signs of psychopathology without debilitating impairment. Accordingly, many who study psychopathology now prefer dimensional models over categorical models (Krueger, Watson, & Barlow, 2005).
