The Diagnostic and Statistical Manual (DSM) is used by mental health professionals for diagnosing and assigning psychological disorders. Within the DSM is a section on personality disorders. Personality disorders can be thought of as extremely unhealthy examples of the personality types. Personality types may reveal characteristics similar to the personality disorders but to a much less dysfunctional degree.

The DSM personality disorders do not match the types 100%. Some types are closer matches than others. The list below is my attempt to assign the types to their closest match in the DSM IV. A brief description from the DSM IV is included below each personality disorder.

1. Obsessive-Compulsive Personality Disorder
   is a pattern of preoccupation with orderliness, perfectionism, and control.
2. Histrionic Personality Disorder
   is a pattern of excessive emotionality and attention seeking.
3. Narcissistic Personality Disorder
   is a pattern of grandiosity, need for admiration, and lack of empathy.
4. Borderline Personality Disorder
   is a pattern of instability in interpersonal relationships, self-image, and affects, and marked impulsivity.
5. Schizoid Personality Disorder
   is a pattern of detachment from social relationships and a restricted range of emotional expression.
6. Paranoid Personality Disorder
   is a pattern of distrust and suspiciousness such that others' motives are interpreted as malevolent.
7. Narcissistic Personality Disorder
   is a pattern of grandiosity, need for admiration, and lack of empathy.
8. Antisocial Personality Disorder
   is a pattern of disregard for, and violation of, the rights of others.
9. Dependent Personality Disorder
   is a pattern of submissive and clinging behavior related to an excessive need to be taken care of.

In my experience, some of the subtypes do not correspond very closely with the disorders. This is particularly true with types 3, 6 and 9.
