Narcissistic personality disorder (NPD) is described in the Diagnostic and Statistical Manual of Mental Disorders (DSM IV-TR; American Psychiatric Association, 2000) as “a pervasive pattern of grandiosity, need for admiration, and lack of empathy,” and it is identified by nine criteria. People with NPD have a grandiose sense of self-importance and accompanying grandiose fantasies. They believe that they are special and unique, and they have a strong need for admiring attention. Considered to lack empathy, that is, being unwilling or unable to recognize the feelings and needs of others, they come across as arrogant and haughty. They have a sense of entitlement, with expectations of receiving special treatment and exceptions, and tendencies to be exploitive and take advantage of other people. Envy of others is common, or alternatively, they believe that others envy them because of their specialness or talents.
