The Prevalence of Personality Disorders in the Greater-Reykjavik Area
The prevalence of personality disorders vas estimated in
a sample of 805 individuals randomly selected from the
greater Reykjavik area. The sample consisted of 3 equally
large cohorts of persons born in 1931,1951 and 1971.
The individuals were asked to participate in a survey
of mental health. Of those contacted, 52% of the total
group participated. The instrument used for estimating
personality disorders was the DIP-Q. The results show
that the overall percentage with any disorder was 11 %
according to DSM-IV and 12 % according to ICD-10. The
most frequent disorder of the whole group, according to
DSM-IV criteria, was obsessive-compulsive personality
disorder (7.3 %) and schizotypal personality disorder
according to ICD-10 criteria, which was to be found in 9%
of the group. Other disorders were less frequently found.
Comorbidity was high among those with a personality
disorder. Of those with disorders according to DSM-IV,
67% had more than one disorder. Similarly, according to
the ICD criteria, comorbidity was to be found in 80% of the
sample.
Among women, anxious/avoidant personality disorder
was the most common, with the highest sub-group
prevalence found among those born in 1971. Similarly,
among the men, schizotypal personality disorder was the
most common, and most commonly found in the 1971 age
group.
