Information processing in anorexia nervosa (AN) has been characterised as having a tendency to get trapped in detail, and having difficulties with set-shifting. These characteristics can be addressed in treatment through personalised interventions targeting thinking styles and their role in the development and maintenance of an eating disorder (ED). This paper outlines a three-session assessment and feedback module designed to identify and address these information processing biases. Two case reports are presented to illustrate the structure, content and outcome of the intervention. Both patients described the intervention as helpful in providing a structure and rationale for the steps required in recovery. The short nature and promising results of this intervention make it an attractive addition to current treatment programmes. Copyright (C) 2008 John Wiley & Sons, Ltd and Eating Disorders Association.
