PSYC 406 Lecture Notes - Lecture 16: Histrionic Personality Disorder, Narcissistic Personality Disorder, Paranoid Personality Disorder
Document Summary
Around 9-15% of the general population (rates much higher in psychiatric hospitals, outpatient clinics) Prevalence of individual pds (personality disorder) is around 1-5% Comorbidity among pds very high people with a pd have an average of 6 comorbid pds. This is probably because there are similar traits underpinning multiple disorders. If you are very impulsive, this feeds into multiple disorders. Comorbidity with other disorders is also very high. If you are neurotic, the same thing applies. Although there may be a big gender bias. Could be due to gender bias in the diagnosis of pds (e. g. , histrionic and sex) Some psychologists only remember a few traits for each disorder. E. g. , histrionic personality disorder: you tend to be promiscuous. Psychologists tend to assign this trait much more often to women. Women and men roughly equal in older age. Personality disorders are not common above the age of 50-55. Even though personality disorders are believed to be stable across life.
