What is the definition of a personality disorder?
Inflexible and maladaptive traits that are pervasive and stable. Their ways of perceiving, thinking, and
behaving compromise their ability to function effectively and relate to other people and the
environment. They experience chronic interpersonal difficulties, problems with identity or sense of
self, and are unable to function in an adaptive manner.
What are the general DSM criteria for diagnosing personality disorders?
The person's enduring pattern of behavior must be pervasive and inflexible, as well as stable and of
long duration. It must also cause either clinically significant distress or impairment in functioning and
be manifested in at least two of the following areas: cognition, affectivity, interpersonal functioning,
or impulse control.
What is the approximate prevalence of personality disorders in the general population?
Somewhere between 10 and 12 percent of people in the general population likely meet criteria for at
least one personality disorder.
What are three reasons for the high frequency of misdiagnoses of personality disorders?
1. Even with structured interviews, the reliability of diagnosing personality disorders typically is less
than ideal because many of the symptoms of specific personality disorders are not very precisely
defined. A great deal of judgment is needed to know if a person's behavior meets the standard in
each case. 2. Many different interviews and self report measures can be used to assess personality
and personality disorders but there is not always high agreement between the diagnoses made with
one instrument versus another. 3. Classifying personality disorders in a categorical manner may not
be the best approach. Most researchers today agree that a dimensional approach for assessing
personality disorders has many advantages and would be preferable.
What are two reasons why it is difficult to conduct research on personality disorders?
It is difficult to determine the causes of personality disorders because most studies to date are
retrospective. 2. Most people with one personality disorder have at least one more personality
disorder as well. This complicates research.

- Little interest in developing social relationships and not emotionally expressive - Viewed by others as
cold and aloof - Prevalence 1% - More common in men than women - Little known on the cause; in
part because such people have little interest in taking part in research
