It's important to clarify that narcissistic personality disorder (NPD) and antisocial personality disorder (ASPD) are relatively rare conditions. Not everyone has traits of these disorders, and the vast majority of people do not meet the diagnostic criteria for NPD or ASPD.
The prevalence of NPD and ASPD in the general population varies, and estimates may change over time as more research is conducted. the prevalence rates were as follows:
Narcissistic Personality Disorder (NPD): The prevalence of NPD is estimated to be around 0.5% to 1% of the general population. NPD is more commonly diagnosed in males than females.
Antisocial Personality Disorder (ASPD): The prevalence of ASPD is estimated to be around 1% to 4% of the general population. It is more commonly diagnosed in males than females as well.
It's important to remember that having some traits associated with these disorders doesn't necessarily mean a person has a clinical diagnosis. Traits can exist on a spectrum, and personality disorders are diagnosed based on a specific set of criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
Most people do not have NPD or ASPD, but many individuals might exhibit certain behaviors or traits that are associated with these disorders at varying levels without meeting the full diagnostic criteria. Personality is a complex and diverse aspect of human psychology, and everyone has their unique combination of traits and behaviors.
