Abstract

Background

Personality status is seldom assessed in community mental health teams except at a rudimentary level. This study challenges the assumption that this policy is either prudent or wise.

Aims

To measure the prevalence of personality disorder within community mental health teams and to investigate its relationship to mental state disorders and overall pathology.

Method

A cross-sectional survey of 2,528 of 2,567 psychiatric patients (98.5%) managed by community mental health teams in four urban settings in the UK in which diagnoses of personality and mental state pathology were assessed separately. Of these, a sample of 400 was interviewed, with a 70.5% completion rate for more in depth information.

Results

In total, 40% of all patients in secondary care suffered from at least one personality disorder. Regression modelling showed personality pathology accounted for a greater degree of global psychopathology than psychosis, alcohol or drug dependence, but was associated with anxiety disorders.

Conclusion

Comorbid personality pathology contributes greatly to overall psychopathology in secondary psychiatric care. It should be both recognised and managed.
