Abstract
One hundred psychiatric emergencies presenting to an inner London teaching hospital had formal assessments of psychopathology, personality disorder (using both ICD-10 and the Personality Assessment Schedule), social networks and social functioning before being randomly assigned to a multidisciplinary community-based team (Early Intervention Service (N = 48) or conventional hospital-based psychiatric services (N = 52) and treated for a period of 12 weeks. The ICD-10 classification yielded a higher proportion (50%) of personality disordered patients than the Personality Assessment Schedule (34%) and those from ethnic minorities (mainly Afro-Caribbean) and upper social classes had a lower incidence of personality disorder. Social networks were smaller in personality disordered patients and there were fewer attachment figures. Improvement in social function, and to a lesser extent with depressive symptomatology, was better in patients with no personality disorder referred to the community service compared with the hospital service. No differences were found between the numbers and duration of social contacts in the two services and it is concluded that the better outcome in the community-treated patients was independent of changes in social networks.
