title: Testosterone, cortisol, and psychopathic traits in men and women.
abstract: Cortisol and testosterone are theorized to independently and jointly influence antisocial behaviors. The current research examined the independent and interactive effects of baseline testosterone and cortisol on individual differences in psychopathic traits in a relatively large non-clinical sample (N=237). Participants completed the Self-Report Psychopathy - Short Form (SRP; Paulhus, Neumann, & Hare, in press) and provided saliva samples. Analyses indicated that testosterone and cortisol were positively correlated with psychopathic traits in men, but beyond these effects, cortisol moderated the relationship between testosterone and psychopathy in men. The relationship between testosterone and psychopathy within men was positive when cortisol levels were high, but negative when cortisol levels were low. These results have implications for work surrounding the dual hormone hypothesis and suggest that nonclinical variability in psychopathy can be predicted by baseline testosterone and cortisol.
