Dr. Clark is a clinical psychologist recruited from the University of Iowa (1993-2010), where she had served as Director of Clinical Training and received the Iowa Regents’ Award for Faculty Excellence in 2006. Her research focuses on the assessment of personality disorder, for which she developed the Schedule for Nonadaptive and Adaptive Personality (SNAP), a psychological test that measures personality traits across the normal-abnormal spectrum. She is widely published and is one of the Institute for Scientific Information (ISI)’s “most highly cited” psychologists. She is one of 9 members of the Work Group to revise the Personality and Personality Disorders section of the DSM-5, the widely used diagnostic and classification system of mental disorders of the American Psychiatric Association, and also served on several cross-cutting Study Groups for the DSM revision.

Professor Clark’s primary research focus is the assessment of personality traits across the adaptive-maladaptive spectrum and the diagnosis of personality disorder. Her current research, funded by the National Institute of Mental Health, aims to identify the core elements of personality pathology and psychosocial disability that are needed to diagnose personality disorder. In particular, her research involves increasing our understanding of (1) the specific traits that comprise each of the major domains of personality (e.g., social withdrawal and reduced capacity for pleasure are components of the broad domain of Detachment vs. Extraversion); (2) determining the core deficits in identity and interpersonal relationships that underlie personality disorder and exploring how to assess these elements independently of personality traits; and (3) deepening our understanding of—and ability to assess—psychosocial dysfunction in relation to personality dysfunction.
