Webinar Summary

Dissociation is a defense mechanism that enables a person to cope with overwhelming or traumatic experiences. It is one of the most common mental health diagnoses with one in ten people meeting the criteria for a dissociative disorder during their lifetime.  It is also one of the most misunderstood and overlooked mental health presentations. Many individuals with a dissociative disorder have experienced complex trauma during childhood and the majority have comorbidities. These include depression, anxiety, PTSD, OCD, bipolar, eating disorders, borderline personality disorder, psychosis, and somatic, sleep, and substance use disorders. The comorbid disorders are most often the focus of treatment, yet the individual is unlikely to make significant progress unless the underlying dissociation is identified and addressed.

In this webinar, Dr Mary-Anne Kate will explore dissociation and the dissociative disorders in adults and adolescents, including the prevalence, causes, and diagnostic features. She will introduce participants to the Multidimensional Inventory of Dissociation – 60 item version (MID-60) for adults and the adolescent version (MID-60-A).  Mary-Anne will then guide participants through a series of case studies, including dissociative identity disorder, other specified dissociative disorder, dissociative amnesia, depersonalization disorder, and PTSD – dissociative subtype, to demonstrate the scoring and interpretation of the MID-60.
