PD-NOS Personality Disorder
Personality Disorder Not Otherwise Specified
Mixed Personality Disorder
A Personality Disorder Not Otherwise Specified or PD-NOS diagnosis is usually given when a person satisfies the general personality disorder criteria under the DSM-IV-TR but does not fit completely with any other personality disorder criteria.
The ICD-10 also has a PD-NOS disorder called Personality Disorder, unspecified. As with the DSM-IV, a general personality disorder criteria has to be met first before any diagnosis can be given.
A PD-NOS diagnosis can also be given in place of these other personality disorders:
- Sadistic Personality Disorder.
- Self defeating Personality Disorder.
- Depressive Peronality Disorder.
- Passive-aggressive personality Disorder.
The above four personality disorders have been excluded from the DSM-IV-TR, so people who would have been diagnosed with any of the above personality disorders might be given the PD-NOS diagnosis instead.
