ABSTRACT
There is general agreement that the classification of personality disorders in DSM-IV is unsatisfactory. We systematically reviewed all studies that have analyzed patterns of personality disorder symptoms and signs in psychiatric patients; twenty-two papers were included in the final synthesis. There is reasonable consistency over the number and type of personality pathology traits reported despite differing samples, varying assessment methods, and different statistical manipulations. There are three or four high order traits; an externalizing factor incorporating borderline, narcissistic, histrionic, and antisocial traits (the latter is sometimes recorded as a separate trait); an internalizing factor incorporating avoidant and dependent traits; a schizoid factor; and often a compulsive factor. Using these domains of personality pathology would simplify classification, have higher clinical utility, and allow relatively easy translation of current research.

OBJECTIVE: The aim of this study was to determine the factors associated with receipt of different levels of shared care, and the effect of shared care on patient outcomes. METHOD: A total of 349 patients with severe mental illness were selected from general practice lists. Patient functioning was assessed using standardised questionnaires, and GPs completed a questionnaire about patients' shared care arrangements at baseline (response-rate 79%). Patients were followed up at 12 months. RESULTS: Receipt of high shared care was associated with greater patient satisfaction with services and social functioning at baseline (p < 0.005). Patients receiving high shared care showed greater improvements in SF-12 mental health scores at follow-up compared to low shared care groups (p = 0.02). This effect was abolished after adjustment for age, sex and psychiatric diagnosis. CONCLUSION: Receipt of high shared care was not associated with demographic or clinical characteristics. High shared care had limited value for patients in terms of improved clinical, social or general health functioning over one year.
