The Dark Path to Antisocial Personality Disorder

An article in (ScienceDaily.com) reporting on personality disorders, stated, with no lab tests to guide the clinician, psychiatric diagnostics is challenging and controversial.  Antisocial personality disorder is defined as “a pervasive pattern of disregard for, and violation of, the rights of others that begins in childhood or early adolescence and continues into adulthood,” according to the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) of the American Psychiatric Association.

DSM-IV provides formal diagnostic criteria for every psychiatric disorder.  This process may be guided by rating scales that measure the traits and features associated with a personality disorder.  But, until now, no one has studied the dimensional structure associated with the DSM antisocial personality disorder criteria.
