Assessment of Trauma-Related Dissociation – Introducing the Trauma and Dissociation Symptoms Interview. To be published by Norton publishers New York.

Trauma-related dissociative disorders are increasingly being considered in therapeutic practice and the clinical literature. On the one hand, dissociative disorders are still too often overlooked, on the other hand, they are also diagnosed more frequently when not actually present. This book elaborates on the assessment of these disorders, using the diagnostic instrument, the Trauma and Dissociation Symptoms Interview (TADS-I )  developed by me over the past decades.

I first address the dilemmas regarding the diagnostic criteria of dissociative disorders in the DSM-5 and ICD-11. I describe what dissociative symptoms actually are and  how a clinician can recognize these symptoms and differentiate form other alterations of consciousness.

Several thematic chapters discuss key differential diagnostic considerations and illustrate them with case reports. Also discussed are the occurrence of false-negative and false-positive diagnoses of trauma-related dissociative disorders, the assessment of traumatic experiences and the development of a treatment plan.

This book is first and foremost intended for clinicians (psychiatrists, clinical psychologists, psychotherapists and nursing specialists) who want to (learn to) diagnose dissociative disorders. For colleagues who do not perform the assessment of dissociative disorders, it provides a lot of information aimed to assist clinicians to better recognize patients with dissociative symptoms and to refer them for specialized diagnostic testing.

The complete TADS-I diagnostic tool is included in the book and available for download.

img_book-trauma-enA patient-oriented manual for complex trauma survivors.

This training manual for patients who have a trauma-related dissociative disorder includes short educational pieces, homework sheets, and exercises that address ways in which dissociation interferes with essential emotional and life skills, and support inner communication and collaboration with dissociative parts of the personality. Topics include understanding dissociation and PTSD, using inner reflection, emotion regulation, coping with dissociative problems related to triggers and traumatic memories, resolving sleep problems related to dissociation, coping with relational difficulties, and help with many other difficulties with daily life. The manual can be used in individual therapy or structured groups.

There is also a Polish (Jagiellonian University Press), Turkish (Psikonet Yayincilik ve Egitim A.S.) and Chinese (Babel Books) translation available.

Treating trauma-related dissociation

The book offers an overview of the neuropsychology of dissociation as a disorder of non-realization, as well as chapters on assessment, prognosis, case formulation, treatment planning, and treatment phases and goals, based on best practices. The authors describe what to focus on first in a complex therapy, and how to do it; how to help patients establish both internal and external safety without rescuing; how to work systematically with dissociative parts of a patient in ways that facilitate integration rather than further dissociation; how to set and maintain helpful boundaries; specific ways to stay focused on process instead of content; how to deal compassionately and effectively with disorganized attachment and dependency on the therapist; how to help patients integrate traumatic memories; what to do when the patient is enraged, chronically ashamed, avoidant, or unable to trust the therapist; and how to compassionately understand and work with resistances as a co-creation of both patient and therapist. Click here to buy

Warmly recommended:

Daring to Care model is a group intervention developed to target specifically trauma-symptoms of parents surviving from childhood abuse. Its goal is to prevent intergenerational harmful effects of traumatization by helping parents understand their trauma-related difficulties and find better ways to regulate and cope with them. Daring to Care is designed as an add-on to individual psychotherapeutic treatment. The model consists of 24 topics presented over the course of 30 sessions, each with its own set of exercises and assignments to encourage individual experiential reflection.  The Daring to Care intervention can be used for parents with different traumatic experiences in their early care-taking relationships, varying trauma symptoms, and children of different ages from birth to 18 years. The Daring to Care model has been developed to address some of the specific difficulties that traumatized parents struggle with, in order to help them break the intergenerational chain of maltreatment and neglect. More info
