Personality disorder not otherwise specified (PD-NOS) is a subclinical diagnostic classification for some DSM-IV Axis II personality disorders not listed in DSM-IV.[1]

The DSM-5 does not have a direct equivalent to PD-NOS. However, the DSM-5 other specified personality disorder and unspecified personality disorder are substantially comparable to PD-NOS. Additionally, Personality disorder-trait specified (PD-TS) remains under consideration for future revisions and is presented as an alternative, more generic approach to personality disorders in the form of "general criteria for personality disorder" which primarily assesses "impairments in personality functioning".[2]

Diagnostic criteria

DSM-IV-TR

This diagnosis may be given when no other personality disorder defined in the DSM fits the patient's symptoms.[3]

Four personality disorders were excluded from the main body of the DSM-IV-TR but this diagnosis may be used instead. The four excluded personality disorders are:

It is a requirement of DSM-IV that a diagnosis of any personality disorder also satisfies a set of Diagnostic criteria.

ICD-10

The World Health Organization's ICD-10 defines a conceptually similar disorder to "personality disorder not otherwise specified" called (F60.9) Personality disorder, unspecified.

It is a requirement of ICD-10 that a diagnosis of any personality disorder also satisfies a set of Diagnostic criteria.

Epidemiology

In one study, PDNOS was found to be the third most frequent personality disorder diagnosis.[4]
