Personality Disorder Statistics


How Common Are Personality Disorders?

A number of studies have been conducted in recent years to determine the prevalence of personality disorders in the general US population.

According to a 2007 study, 9.1% of the US population (about 1 in 11 people) meet the DSM-IV criteria for a personality disorder. Two previous smaller surveys have estimated the percentage between 9.0% and 15.7%.

Comorbidity Between Personality Disorders

The following table shows statistically how likely it is that a person who is diagnosed with one personality disorder will also be diagnosed with another personality disorder, as defined by the American Psychiatric Association's Diagnostic & Statistical Manual of Mental Disorders (DSM-IV).

The numbers displayed in the table below are a statistical measures of co-occurrence known as "tetrachoric correlations". The more positive the number, the more likely it is that a person will be diagnosed with the second personality disorder listed. The more negative the number, the less likely it is that a person will be diagnosed with the second personality disorder in the table.

Note: This data was compiled from an initial survey of 5692 people in the US. None of the people in the survey sample were identified as meeting the criteria for Histrionic Personality Disorder or Narcissistic Personality Disorder. Therefore, no comorbidity information is shown for HPD or NPD.

Comorbidity Between Personality Disorders and DSM-IV Axis I Disorders

67% of people who meet the DSM-IV criteria for a Personality DIsorder have been found in a 2007 study to also meet the criteria for at least one of the DSM-IV Axis I disorder. The table below shows the probability that a person who has been diagnosed with a personality disorder will also meet the criteria for each of the following Axis I disorders, as defined by the American Psychiatric Association's Diagnostic & Statistical Manual of Mental Disorders (DSM-IV):

Axis I Disorder Comorbidity
Anxiety Disorders 52.4%
- Generalized Anxiety Disorder (GAD) 15.2%
- Specific phobia 23.4%
- Social phobia 26.3%
- Panic disorder 10.0%
- Adult separation anxiety disorder (ASAD) 8.9%
- Post Traumatic Stress Disorder (PTSD) 14.1%
Mood Disorders 24.1%
- Major Depressive Disorder (MDD) 13.4%
- Dysthymia 10.8%
- Bipolar I or II 8.1%
Impulse Control Disorders 23.2%
- Intermittent Explosive Disorder (IED) 15.9%
- Attention Deficit Disorder (ADD) 11.0%
Substance Abuse 22.6%
- Alcohol abuse or dependence 10.9%
- Drug abuse or dependence 5.6%
- Tobacco dependence 11.8%
Any DSM-IV Axis I Disorder 67.0%

Source: Lenzenweger et al, 2007 - DSM-IV personality disorders in the National Comorbidity Survey Replication

Note that although 67% of the people meeting the criteria for an Axis II - or personality disorder also meet the criteria for an Axis I disorder, the reverse is not true. Only 24.8% of people meeting the criteria for an Axis I disorder also meet the criteria for an Axis II disorder.

Child Abduction Statistics

Definition:

Child Abduction - Child Abduction is a serious, yet common occurrence when people who suffer from personality disorders become involved in a custody dispute. Approximately 82% of more than 200,000 child abductions every year are perpetrated by family members.

Description:

U.S. Department of Justice statistics show that 9% of reported missing children cases are the result of child abductions and that 82% of reported child abductions in the US are determined to have been committed by family members.

Episode Type  Reported Cases  % of Missing % of Abductions
Reported Missing Children 797,500 100%
Runaway/Thrown Away 357,600 45%
Missing, Benign Explanation 340,500 43%
Missing involuntary, lost, injured 61,900 8%
Family abduction 56,500 7% 82%
Non family abduction 12,100 2% 18%
Stereotypical abduction* 115 0% 0%

Source: US Dept. of Justice Office of Juvenile Justice & Delinquency Prevention

*Stereotypical kidnappings are the particular type of non family abduction that receives the most media attention and involves a stranger or slight acquaintance who detains the child overnight, transports the child at least 50 miles, holds the child for ransom, abducts the child with intent to keep the child permanently, or kills the child.

Family Member Child Abduction Prevalence

An estimated 203,900 children were victims of a family abduction in 1999. In 43% of these cases, the whereabouts of the abducted child was known to the child's caretaker.

1999 Child abductions by a family member 203,900 100%
Whereabouts unknown to caretaker 117,200 57%
Whereabouts known to caretaker 86,700 43%
Abduction Reported to Authorities 56,500 28%

Source: US Dept. of Justice Office of Juvenile Justice & Delinquency Prevention

Abduction Perpetrator Statistics

In 78% of cases one of the child's parents is the abductor with abduction by the father occurring 2 times as often as abduction by the mother. However, it should be noted that in disputed custody cases, the child's mother is 7 times more likely to be granted sole custody than the child's father, which heavily influences the numbers.

Abduction Duration

In most cases, family child abductions are short-lived and will not serve the abductor well. Most courts look unfavorably on anyone who abducts children or tries to deny another parent access in that way.

Abduction Duration    
Less than 1 hour              6,300 3%
1-6 hours           33,600 16%
7-24 hours              7,500 4%

US Child Custody Statistics

Many people believe that mothers are naturally better caregivers than fathers. And the US courts seem to agree. US Divorce Statistics show that a divorcing mother is 7 times more likely to retain sole custody of her children than a father:

USA 1990 Custody Statistics (19 States reporting) Percentage
Sole possession granted to mother 72.5%
Sole possession granted to father 10.3%
Joint possession 15.7%
Possession granted to other person(s) 1.4%

Source: http://www.divorcepeers.com/stats17.htm

Fathers, who want to protect their children from an abusive mother, are sometimes afraid to take legal action because they fear:

  • Facing ridicule or disbelief from police or social services.
  • Losing all contact with their children at the hands of a gender-biased legal system
  • Facing steep legal costs.
  • Facing abuse themselves at the hands of the perpetrator
  • Being judged by their communities, families and friends.

Child Support Statistics

When it comes to child support, US census data indicates that:

  • 79.6% of custodial mothers receive a child support award
  • 29.9% of custodial fathers receive a child support award

US census data also indicates that fathers are more likely to fulfil their child support obligations than mothers:

  • 43% of moms required to pay child support are "deadbeat moms" - i.e. they default on 100% of the money they owe,
  • 32% of dads required to pay child support are "deadbeat dads" - i.e. they default on 100% of the money they owe.

One of the reasons that "deadbeat dads" get most of the bad press in the popular media is that there are a lot more of them - primarily for 2 reasons:

  • There are 7 times more fathers than mothers who do not have primary custody of the children.
  • Fathers are 3 times more likely than mothers to be ordered to pay child support than their female counterparts.
