Diagnosis
[edit] ICD-10
The World Health Organization's International Statistical Classification of Diseases and Related Health Problems, tenth edition (ICD-10), defines a conceptually similar disorder to antisocial personality disorder called (F60.2) Dissocial personality disorder.[4]
It is characterized by at least 3 of the following:
1.Callous unconcern for the feelings of others.
2.Gross and persistent attitude of irresponsibility and disregard for social norms, rules, and obligations.
3.Incapacity to maintain enduring relationships, though having no difficulty in establishing them.
4.Very low tolerance to frustration and a low threshold for discharge of aggression, including violence.
5.Incapacity to experience guilt or to profit from experience, particularly punishment.
6.Markedly prone to blame others or to offer plausible rationalizations for the behavior that has brought the person into conflict with society.
There may be persistent irritability as an associated feature.
The diagnosis includes what may be referred to as amoral, antisocial, psychopathic, and sociopathic personality (disorder).
The criteria specifically rule out conduct disorders.[5] Dissocial personality disorder criteria differ from those for antisocial and sociopathic personality disorders.[6]
It is a requirement of ICD-10 that a diagnosis of any specific personality disorder also satisfies a set of general personality disorder criteria.
Psychopathy and sociopathy
Although there are behavioral similarities, ASPD and psychopathy are not synonymous. A diagnosis of ASPD using the DSM criteria is based on behavioral patterns, whereas psychopathy measurements also include more indirect personality characteristics. The diagnosis of antisocial personality disorder covers two to three times as many prisoners as are rated as psychopaths. Most offenders scoring high on the PCL-R also pass the ASPD criteria but most of those with ASPD do not score high on the PCL-R.[3]
Sociopathy is also distinct from ASPD as well as psychopathy. Hare writes that the difference between sociopathy and psychopathy may "reflect the user's views on the origins and determinates of the disorder." The term sociopathy may be preferred by sociologists that see the causes as due to social factors.
The term psychopathy may be preferred by psychologists who see the causes as due to a combination of psychological, genetic, and environmental factors.[7]
