Efficacy of an early intervention based on acceptance and commitment therapy for adults with depressive symptomatology: Evaluation in a randomized controlled trial.

Objective: The current study examined the efficacy of an early intervention based on acceptance and commitment therapy (ACT) for depressive symptomatology. The ACT intervention is aimed at increasing the acceptance of negative thoughts and emotions and living a mindful and value-based life.

Method: Adults with mild to moderate depressive symptomatology were randomly assigned to the ACT intervention (n=49) or to a waiting list (n=44).

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.
