There are currently 10 diagnosable PD's on the DSMv and I would be interested to learn what personality types they may have originated from. They are now grouped under Axis II disorders but used to be grouped in clusters as follows:-

Cluster A - odd or eccentric disorders

paranoid personality disorder - characterized by irrational suspicions and mistrust of others

schizoid personality disorder - characterized by a lack of interest in social relationships, seeing no point in sharing time with others, anhedonia, introspection.

schizotypal personality disorder - characterized by odd behavior or thinking.


Cluster B - dramatic, emotional or erratic disorders

borderline personality disorder - extreme "black and white" thinking, instability in relationships,
self-image, identity and behavior.

antisocial personality disorder - a pervasive disregard for the law and the rights of others

narcissistic personality disorder - a pervasive pattern of grandiosity, need for admiration, and a lack
of empathy.

histrionic personality disorder - pervasive attention-seeking behavior including inappropriate sexual
seductiveness and shallow or exaggerated emotions.

(note: psychopaths and sociopaths seem to be grouped in with APD/NPD)


Cluster C - anxious or fearful disorders

avoidant personality disorder - social inhibition, feelings of inadequacy, extreme sensitivity to
negative evaluation and avoidance of social interaction.

dependent personality disorder - pervasive psychological dependence on other people.

obsessive-compulsive personality disorder (not the same as OC disorder) -characterized by rigid conformity to rules, moral codes and excessive orderliness.


2 Disorders for further study but not currently on the DSMv are:-

Depressive personality disorder - is a pervasive pattern of depressive cognitions and behaviors beginning by early adulthood.

Passive-aggressive personality disorder (negativististic personality disorder) - is a pattern of negative attitudes and passive resistance in interpersonal situations.


2 disorders that were previously on the DSMIII but were deleted for further study are:-

Sadistic personality disorder - is a pervasive pattern of cruel, demeaning and aggressive behavior.

Self-defeating personality disorder (masochistic personality disorder) - is characterised by behaviour consequently undermining the person's pleasure and goals.

Any insights would be very welcome. Thanks.
