Antisocial personality disorder is characterized by a pervasive pattern of disregard for consequences and for the rights of others. Diagnosis is by clinical criteria. Treatment may include cognitive-behavioral therapy, antipsychotic drugs, and antidepressants.

People with antisocial personality disorder commit unlawful, deceitful, exploitative, reckless acts for personal profit or pleasure and without remorse; they may do the following:

  • Justify or rationalize their behavior (eg, thinking losers deserve to lose, looking out for number one)

  • Blame the victim for being foolish or helpless

  • Be indifferent to the exploitative and harmful effects of their actions on others

For antisocial personality disorder, estimated 12-month prevalence rates in the US (based on older Diagnostic and Statistical Manual of Mental Disorders [DSM] criteria) range from about 0.2 to 3.3%. Antisocial personality disorder is more common among men than among women (6:1), and there is a strong heritable component. Prevalence decreases with age, suggesting that patients can learn over time to change their maladaptive behavior.

Etiology of Antisocial Personality Disorder

Both genetic and environmental factors (eg, abuse during childhood Overview of Child Maltreatment Child maltreatment is behavior toward a child that is outside the norms of conduct and entails substantial risk of causing physical or emotional harm. Four types of maltreatment are generally... read more Overview of Child Maltreatment ) contribute to the development of antisocial personality disorder. A possible mechanism is impulsive aggression, related to abnormal serotonin transporter functioning. Disregard for the pain of others during early childhood has been linked to antisocial behavior during late adolescence.

Antisocial personality disorder is more common among 1st-degree relatives of patients with the disorder than among the general population. Risk of developing this disorder is increased in both adopted and biologic children of parents with the disorder.

Risk of conduct disorder evolving into antisocial personality disorder may be increased when parents abuse or neglect the child or are inconsistent in discipline or in parenting style (eg, switching from warm and supportive to cold and critical).

Symptoms and Signs of ASPD

Patients with antisocial personality disorder may express their disregard for others and for the law by destroying property, harassing others, or stealing. They may deceive, exploit, con, or manipulate people to get what they want (eg, money, power, sex). They may use an alias.

These patients are impulsive, not planning ahead and not considering the consequences for or the safety of self or others. As a result, they may suddenly change jobs, homes, or relationships. They may speed when driving and drive while intoxicated, sometimes leading to crashes. They may consume excessive amounts of alcohol or take illegal drugs that may have harmful effects.

Patients with antisocial personality disorder are socially and financially irresponsible. They may change jobs with no plan for getting another. They may not seek employment when opportunities are available. They may not pay their bills, default on loans, or not pay child support.

These patients are often easily provoked and physically aggressive; they may start fights or abuse their spouse or partner. In sexual relationships, they may be irresponsible and exploit their partner and be unable to remain monogamous.

Remorse for actions is lacking. Patients with antisocial personality disorder may rationalize their actions by blaming those they hurt (eg, they deserved it) or the way life is (eg, unfair). They are determined not to be pushed around and to do what they think is best for themselves at any cost.

These patients lack empathy for others and may be contemptuous of or indifferent to the feelings, rights, and suffering of others.

Patients with antisocial personality disorder tend to have a high opinion of themselves and may be very opinionated, self-assured, or arrogant. They may be charming, voluble, and verbally facile in their efforts to get what they want.

Diagnosis of ASPD

  • Clinical criteria (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition [DSM-5])

For a diagnosis of antisocial personality disorder, patients must have

  • A persistent disregard for the rights of others

This disregard is shown by the presence of 3 of the following:

  • Disregarding the law, indicated by repeatedly committing acts that are grounds for arrest

  • Being deceitful, indicated by lying repeatedly, using aliases, or conning others for personal gain or pleasure

  • Acting impulsively or not planning ahead

  • Being easily provoked or aggressive, indicated by constantly getting into physical fights or assaulting others

  • Recklessly disregarding their safety or the safety of others

  • Consistently acting irresponsibly, indicated by quitting a job with no plans for another one or not paying bills

  • Not feeling remorse, indicated by indifference to or rationalization of hurting or mistreating others

Also, patients must have evidence that a conduct disorder has been present before age 15 years. Antisocial personality disorder is diagnosed only in people 18 years.

Differential diagnosis

Antisocial personality disorder should be distinguished from the following:

Treatment of ASPD

  • In some cases, cognitive-behavioral therapy and sometimes certain drugs

There is no evidence that any particular treatment leads to long-term improvement. Thus, treatment aims to reach some other short-term goal, such as avoiding legal consequences, rather than changing the patient. Contingency management (ie, giving or withholding what patients want depending on their behavior) is indicated.
