title: Reducing the cost of dissociative identity disorder: Measuring the effectiveness of specialized treatment by frequency of contacts with mental health services.
abstract: It is important to understand and record the impact of therapy on severe mental health conditions through the use of clinical assessment measures. In this article, I propose to extend outcome evaluation by measuring service use and cost prior to and during the commencement of psychological therapy over a period of 4 years for 2 people diagnosed with dissociative identity disorder. The treatment was provided within an outpatient setting in a U.K. National Health Service hospital trust following therapeutic guidelines set out by the International Society for the Study of Trauma and Dissociation. Results show that service use in both inpatient and out-of-hours crisis services reduced as the 2 people received therapy over the 4-year time period. Based on these 2 cases, it appears to be cost effective to provide specialized therapy for dissociative identity disorder in outpatient settings.
