For making accurate and formal diagnoses of dissociative identity disorder, there is no better assessment instrument than the SCID. Because of the detailed, nonpathologizing discussion of dissociative symptoms it encourages, the SCID-D facilitates gathering a detailed understanding of the client's symptoms and struggles that can be invaluable in any trauma therapy. Even when there is no immediate need for formal assessment and diagnosis, the therapist who is curious and concerned about a client's dissociative symptoms can still benefit from utilizing portions of the SCID-D as the work of information-gathering in therapy naturally proceeds. Many of the SCID-D questions can simply be incorporated into the therapeutic dialogue.—Janina Fisher, Ph.D., Author, Healing the Fragmented Selves of Trauma Survivors and Transforming the Living Legacy of Trauma: A Workbook for Survivors and Therapists

The SCID-D continues to serve as the gold-standard therapeutic and research assessment for dissociation. I use it frequently in my practice to thoroughly and gently assess for the spectrum of dissociative symptoms with new referrals. I have also used it with existing clients and am regularly surprised with new information gathered and a deepened understanding of dissociative processes.—Matthew A. Robinson, Ph.D., Director, McLean Outpatient Trauma Clinic; Director of Clinical Services, McLean Hill Center; Instructor of Psychology, Harvard Medical School

The SCID-D has dramatically advanced our research and understanding of dissociative disorders. All clinicians, especially those who treat people suffering from complex traumatization, should keep one copy on their desk.—Prof. Adriano Schimmenti, Ph.D., D.Clin.Psych., Full Professor of Psychopathology and Director of the Postgraduate Degree in Clinical Psychology, UKE–Kore University of Enna; Scientific Director, IIPP–Italian Institute of Psychoanalytic Psychotherapy; Associate Editor, Clinical Neuropsychiatry; Associate Editor, European Journal of Trauma & Dissociation

The SCID-D interview has proven to be the most clinically sensitive and scientifically rigorous assessment tool in the field of dissociation and complex trauma. I have found it to be indispensable in my clinical and forensic work over the past 25 years. Not only does the SCID-D detect previously hidden dissociation, the interview questions elicit therapeutically relevant information useful in therapy well beyond the diagnostic process. The SCID-D should be used by any clinician seeking to provide a gold standard assessment and treatment to clients suffering from complex post-traumatic and dissociative symptoms and disorders.—Dr. Pamela Hall (Psy.D), Clinical Psychologist; Founder and President of the New Jersey Society for the Study of Trauma and Dissociation

Dr. Steinberg has developed a diagnostic instrument for dissociative symptoms and disorders that has proven over the last 30 years to be immensely useful in clinical practice and research. With the new edition of the SCID-D, clinicians around the world are now able to use the interview to assess dissociative symptoms under either DSM or ICD criteria. Accurate assessment is essential for appropriate treatment of dissociative disorders and other disorders related to complex traumatization, and in this application the SCID-D definitely remains the diagnostic gold standard in the field.—Olivier Piedfort-Marin, Ph.D., President-Elect, EMDR Europe Association; Honorary President, French-Speaking Association of Trauma and Dissociation; Associate Editor, European Journal of Trauma and Dissociation
