This study shows good agreement between GP case records and a self-complete questionnaire for the reporting of GP visits. However, differences in costs associated with those visits arose due to differences in the method used for calculating length of visit.

Personality disorders are not independently associated with increased costs. An interaction between personality disorders and common mental disorders significantly predicts increased total costs.

Personality disorder, as rated by a research interview, is a predictor of health service usage. There is a significant disparity between a research rating of personality disorder and the diagnostic ratings made by GPs. The GP ratings of personality disorder were strongly associated with adverse perceptions of the patient's consulting behaviour.
