Abstract
Previous research has demonstrated a relationship between perinatal factors, genetic factors, and some kinds of antisocial behavior. The current project investigates the possibility of a similar relationship between perinatal difficulties and/or genetic factors and Antisocial Personality Disorder (ASP). The Danish birth cohort examined here consists of 94 Danish men, half of whom (N = 47) had evidenced serious criminal behavior by age 36. Of these criminal men, 12 met the DSM-III diagnostic criteria for Antisocial Personality Disorder. The results showed no relationship between ASP, genetic variables, and perinatal complications and are interpreted as implying etiological differences between antisocial behavior and Antisocial Personality Disorder.
