Currently, my primary research interests include: (a) psychopathy; (b) other “dark” personality traits such as sadism and spitefulness; and (c) the relative importance of common versus specific factors in psychotherapy. Much of my research on psychopathy is focused on the measurement of psychopathic personality traits, including studies that have used Meehl’s taxometric method to examine whether psychopathy and related disorders (e.g., antisocial personality disorder, intermittent explosive 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. I am also interested in the behavioral correlates of psychopathic personality traits, such as the association between psychopathy and risky sexual behavior. My other area of research uses meta-analytic methods to examine whether various psychological treatments yield similar outcomes (“Dodo bird effect”), whether adding specific components to treatments improves outcomes, and the role of therapist allegiance in psychological assessment and treatment.
