You may want to screen your clients for dissociative disorder by using evaluative tools. The dissociative experiences scale (DES) developed by Bernstein and Putnam (1986) is the most popular of such instruments. The structured clinical interview for DSM-IV Dissociative Disorders-Revised (SCID-D-R) developed by Steinberg (1994) is a widely used diagnostic interview that allows the therapist to assess the severity of five dissociative symptoms and diagnose the DSM dissociative disorders and acute stress disorder.
