Personality Disorders Appear To Be Increasing

Recent research suggests that more and more people are growing up with personality disorders. This may explain why there appears to be an increase in the number of high-conflict people. A recent study done by the National Institutes of Health between 2001 and 2005 suggests an increasing trend in the percentage of people who meet the criteria for a personality disorder. The researchers interviewed over 35,000 people, who were considered representative of the United States population. They analyzed the results by four age groups. The following are the study results for the five personality disorders which I believe are most often associated with high-conflict behavior:
Narcissistic =  6.2% of US population (62% male; 38% female)
Common conflict traits: arrogance, superiority, lack of empathy, insulting, self-centered
