The two main areas that the Adult Psychopathology lab is focused on are

(a) psychopathy and other externalizing disorders, and (b) health anxiety/hypochondria.  Much of our research on psychopathy has used Meehl’s taxometric method to examine whether psychopathy and related disorders (e.g., antisocial personality disorder, conduct disorder) exist along a continuum or are discrete, qualitatively distinct conditions.  In other words, this research is interested in the question of whether there are “psychopaths” who are uniquely different from others or whether psychopathy is a dimensional construct.  The lab is currently examining the behavioral correlates of psychopathic personality traits, such as the association between psychopathy and risky sexual behavior.  Additionally, our research on health anxiety has focused on how dysfunctional beliefs and a ruminative cognitive style contribute to health anxiety and hypochondriasis.
