Personality Disorders 593


in the attic and writing the threatening notes prob-


ably resulted from uncontrollable emotions that


ended up hurting other people (and Reiland) rather


than from a disregard for others.


The diagnostic criteria for antisocial person-

ality disorder are the most behaviorally specific


of the criteria for personality disorders and even


include overt criminal behaviors (Skodol, 2005).


Because of this specificity, antisocial personality


disorder is the most reliably diagnosed personality


disorder (Skodol, 2005). Clinicians may, however,


be biased in how they diagnosis this disorder: One


study found that clinicians in the United Kingdom


were more likely to rate a man described in a case


report as having antisocial personality disorder


when the man was identifi ed as White than when


he was identified as Black (Mikton & Grounds,


2007). And although the criteria are behaviorally


specific, it is not clear whether people with this


personality disorder who perpetrate a criminal act


have a unique constellation of personality traits


not shared by people with this disorder who do


not perpetrate a criminal act (Silverstein, 2007).


Like other personality disorders, antisocial

personality disorder manifests itself in childhood


or adolescence, but DSM-IV-TR is again very spe-


cific about antisocial personality disorder: The


symptoms must have arisen by age 15 (although


the diagnosis cannot be made until the individual is at least 18 years old). The di-


agnosis for people who exhibit a similar pattern of symptoms but are younger than


18 is conduct disorder, which is characterized by consistently violating the rights of


others (through lying, threatening, destructive and aggressive behaviors) or violating


societal norms. (In Chapter 14 we discuss conduct disorder in detail.) Table 13.12


provides additional facts about antisocial personality disorder.


CASE 13.5 • FROM THE OUTSIDE:Antisocial Personality Disorder
John and his sister were adopted by the same family when they were respectively 1.5 and 3
years of age. From the very beginning, John was severely physically abused by his adoptive
father as a result of just minor misbehaviors. Furthermore, John felt that he and his sister were
neglected (lack of warmth and attention) by his adoptive parents and that he and his sister
were thought of much less highly by them than their only biological son. From age 10 John and
his sister were sexually abused on a regular basis by his adoptive father, and John was forced
to watch when his father raped his sister. He demonstrated more and more oppositional and
angry behavior, and he became a notorious thief. John left junior secondary technical school
prematurely and had many short-term jobs, but he was dismissed every time because of lack
of motivation, disobedience, and/or theft. As a consequence of his deviant behavior, John was
placed in a juvenile correctional and observation institute when he was 16 years of age. A psy-
chiatric report from this episode described him as a socially, emotionally, morally, and sexu-
ally underdeveloped person who was very suspicious and angry. He projected his discomfort
on the outside world. After his release from the juvenile correctional institute (when he was
18 years of age), John was arrested because of violent pedophilic rape, theft, and fraud. John
was sentenced to forensic psychiatric treatment. But soon after his release, when he was 24,
John was sentenced to life imprisonment because he committed an excessively violent sexual
homicide on a 9-year-old boy.

Prevalence


  • Between 1% and 4% of Americans are diagnosed with antisocial disorder (American
    Psychiatric Association, 2000; Grant, Hasin, et al., 2004).

  • Around 60% of male prisoners in a number of countries have antisocial personality
    disorder (Moran, 1999).
    Comorbidity

  • The most common comorbid Axis I disorders are anxiety disorders, mood disorders,
    substance-related disorders, and somatization disorders (American Psychiatric Asso-
    ciation, 2000; Compton et al., 2005; Sareen et al., 2004).

  • In a clinical setting, most patients who meet the criteria for antisocial personality
    disorder also are diagnosed with at least one other personality disorder, typically
    another dramatic/erratic personality disorder (Widiger & Corbitt, 1997).
    Onset

  • As required by the DSM-IV-TR criteria, symptoms of conduct disorder emerge before
    age 15, and specifi c symptoms of antisocial behavior occur since age 15. The specifi c
    antisocial behaviors then continue into adulthood.
    Course

  • Antisocial personality disorder has a chronic course, but symptoms may improve as
    patients age, particularly in their 40s (Seivewright, Tyrer, & Johnson, 2002)
    Gender Differences

  • Antisocial personality disorder is diagnosed three times more often in men than in
    women.
