Other and unspecified personality disorders

In all cases of non-specific diagnoses it is a requirement that the person meet the general criteria for personality disorders. Other specified & Other specific The ICD-10 defines the diagnosis Other specific personality disorder () for personality disorders that don't have a separate code. This diagnosis allows the following type specifiers: "eccentric", "haltlose", "immature", "narcissistic", "passive-aggressive", and "psychoneurotic". The DSM-5 contains the similarly named diagnosis Other Specified Personality Disorder (301.89; F60.89), which is used when recording the presence of personality disorder along with the reasons for the condition not being classified as one of the specific personality disorders. This diagnosis is not included in subsequent (DSM-5 and DSM-5-TR) editions of the DSM. The DSM-IV-TR excluded four personality disorders, but this diagnosis may be used instead. The four excluded personality disorders are: • Sadistic personality disorder • Self-defeating personality disorder • Depressive personality disorder • Passive–aggressive personality disorder Severity unspecified In the International Statistical Classification of Diseases and Related Health Problems, 11th Edition ICD-11 of the World Health Organization (WHO), all personality disorders are diagnosed under a single title called "personality disorder” (). The criteria for diagnosis are mainly concerned with assessing dysfunction, distress, and maladaptive behavior. Once a diagnosis has been made, the clinician then can draw upon five trait domains (prominent personality traits or patterns; ) to describe the particular causes of dysfunction, as these have major implications for potential treatments. The unspecified PD diagnosis in the ICD-11 is Personality disorder, severity unspecified (). ==Epidemiology==

The National Comorbidity Survey Replication estimated the prevalence of PD-NOS in the general population at around 1.6% (0.3-2.9%). Comorbidity measures indicated a strong association with antisocial personality disorder (and generally Cluster B), moderate association with obsessive-compulsive personality disorder, and strong negative association with schizoid and dependent personality disorders. A 2004 meta-analysis estimated the prevalence of PD-NOS in patient samples between 8-13%. In structured interview studies it is the third most common diagnosis given, in unstructured studies it is the single most frequent diagnosis. Half the studies did not give further definition for the diagnosis, and those that did used "mixed" most often. In another study, out of 1760 psychotherapy referrals, 21.6% was diagnosed exclusively with PD-NOS. In terms of severity, patients with PD-NOS fell between a formal personality disorder diagnosis and no personality disorder. Patients who received PD-NOS as an additional diagnosis to their formal personality disorder diagnosis had the most severe problems. == See also ==
