Oblivious and hypervigilant
The psychiatrist and psychoanalyst Glen Gabbard described two subtypes of NPD in 1989, later referred to as equivalent to, the grandiose and vulnerable subtypes. The first was the "oblivious" subtype of narcissist, equivalent to the grandiose subtype. It was described as being grandiose, arrogant and thick-skinned, while also exhibiting personality traits of helplessness and emotional emptiness, low self-esteem and shame. These were observed in people with NPD to be expressed as socially avoidant behavior in situations where self-presentation is difficult or impossible, leading to withdrawal from situations where social approval is not given. The second subtype Gabbard described was termed "hypervigilant", equivalent to the vulnerable subtype. People with this subtype of NPD were described as having easily hurt feelings, an oversensitive temperament, and persistent feelings of shame. High functioning or exhibitionist
A third subtype for classifying people with NPD, also initially theorised by Gabbard, is termed high functioning or exhibitionistic. It has been described as "high functioning narcissists [who] were grandiose, competitive, attention-seeking, and sexually provocative; they tended to show adaptive functioning and utilize their narcissistic traits to succeed." Millons subtypes
In the study Disorders of Personality: DSM-IV-TM and Beyond (1996), Theodore Millon suggested five subtypes of NPD, although they did not identify specific treatments per subtype. Mastersons subtypes (exhibitionist and closet)
In 1993, James F. Masterson proposed two subtypes for pathological narcissism, exhibitionist and closet. Both fail to adequately develop an age- and phase- appropriate self because of defects in the quality of psychological nurturing provided, usually by the mother.
A person with exhibitionist narcissism is similar to NPD described in the DSM-IV and differs from closet narcissism in several ways. A person with closet narcissism is more likely to be described as having a deflated, inadequate self-perception and greater awareness of emptiness within. A person with exhibitionist narcissism would be described as having an inflated, grandiose self-perception with little or no conscious awareness of feelings of emptiness. Such a person would assume that their condition was normal and that others were just like them. A person with closet narcissism is described to seek constant approval from others and appears similar to those with borderline personality disorder in the need to please others. A person with exhibitionist narcissism seeks perfect admiration all the time from others. Malignant narcissism
Malignant narcissism, a term first coined in Erich Fromms 1964 book The Heart of Man: Its Genius for Good and Evil, is a syndrome consisting of a combination of NPD, antisocial personality disorder, and paranoid traits. A person with malignant narcissism was described as deriving higher levels of psychological gratification from accomplishments over time, suspected to worsen the disorder. Because a person with malignant narcissism becomes more involved in psychological gratification, it was suspected to be a risk factor for developing antisocial, paranoid, and schizoid personality disorders. The term malignant is added to the term narcissist to indicate that individuals with this disorder have a severe form of narcissistic disorder that is characterized also by features of paranoia, psychopathy (anti-social behaviors), aggression, and sadism.
