The case history of a woman with severe and enduring anorexia nervosa and obsessive–compulsive disorder (OCD) with contamination fears is presented. These contamination fears centred on her fear of contamination by fat and fatty substances as she worried about gaining weight. Previous treatment with graded exposure had shown no clinically significant benefits. She was admitted to a specialist unit for the treatment of OCD as an inpatient. Due to the previous failure of the recognised psychological treatments for OCD it was decided to use the new psychoeducational approach of danger ideation reduction therapy (DIRT). This treatment resulted in an improvement in her OCD symptoms despite the fact that the emphasis of the treatment was on the risk of bacteria and dirt. It is believed that this is the first documented case of DIRT being used for a patient with anorexia nervosa and OCD.
