Cluster B personality disorders

Mental health

Cluster B personality disorders include Antisocial personality disorder, Narcissism, Borderline personality disorder, and Histrionic personality disorder. I am not a fan of medicalising things unnecessarily so I am not going to go around diagnosing people with full-blown cases of these disorders


Bill Eddy, Are Narcissists and Sociopaths Increasing?

Between 2001 and 2005, the National Institutes of Health (NIH) funded the largest study ever done regarding the prevalence of personality disorders in the United States. Structured interviews were done with approximately 35,000 people who were randomly selected to be representative of the U.S. adult population in a variety of ways including age, income, gender and region. This study found that 6.2% of the general population would meet the criteria for NPD (Stinson et al. 2008) and 3.7% would meet the criteria for ASPD (5.5% male and 1.9% female) (Grant et al. 2004).
