Individual-context interaction as a guide in the treatment of personality disorders.

The diagnosis and treatment of personality disorders is strongly influenced by personality theories based on trait models, and the influence of the context is relatively neglected. Developments within psychology and neurobiology have led to the awareness that the manner in which personality characteristics are expressed is strongly determined by interaction with the context. The clinical implications of these developments are set out and Acceptance and Commitment Therapy (Hayes, Strosahl, & Wilson, 1999) is highlighted as a development within psychotherapy that is linked to a contextual diagnosis. Employment reintegration of patients with personality disorders is presented as an example of a context-oriented approach. Neurobiological insights support the idea that active focusing on the outer world reduces negative affects.
