| Prevalence |
Between 2.3% and 4.5% of the general population is estimated to have paranoid personality disorder. |
| Comorbidity |
People with paranoid personality disorder may also have another personality disorder, usually another Cluster A (odd/eccentric) personality disorder (schizoid or schizotypal) or narcissistic, avoidant, or borderline personality disorder. |
| Onset |
Symptoms can first appear in childhood or adolescence, when the person appears hypersensitive, has difficulties with peers, and has odd thoughts or fantasies or uses language unconventionally. |
| Course |
The symptoms of paranoid personality disorder are relatively stable over time (Seivewright et al., 2002). |
| Gender Differences |
Based on surveys in the general population, there is no clear gender difference in the prevalence of paranoid personality disorder. However, among people with this disorder, men are more likely than women to come to the attention of mental health professionals (Morey, Alexander, & Boggs, 2005). |
