Am I crazy ?

For Americans who have wondered, "Am I crazy ?" the answer, it appears, could be easily yes. A 2004 study by the National Epidemiologic Survey on Alcohol and Related Conditions indicated that nearly 15% of adults meet the diagnostic criteria for one or more personality disorders.

For some medical/disease survey in recent years, this one included, I tend to suspect those survey results were inflated by ambiguous or subjective questions. But the surveys with alarming results do inspire more research and a public understanding.

Below are more details on the percentage of Americans adults with personality disorders from that study:

Obsessive, compulsive --- 7.9%

Paranoid --- 4.4%

Antisocial --- 3.6%

Schizoid --- 3.1%

Avoidant --- 2.4%

Histrionic --- 1.8%

Dependent --- 0.5%
