If you’re a clinician or researcher wanting to learn more about the diagnosis of pathological dissociation using an empirically validated and reliable instrument, then you’ve come to to the right place.

Most clinicians have received little or no training about dissociation and dissociative symptoms. This may lead them to fail to notice dissociative symptoms or to misclassify them in terms of a clinical diagnosis with which they are more familiar (e.g., depression, bipolar disorder, or psychosis). Questions about dissociative symptoms are absent from most standard clinical or psychological questionnaires and assessments. This makes the MID, a validated and reliable, 218-item self report inventory, an essential addition to clinical practice – especially when a clinician is serving client populations known to be at-risk for complex trauma. The MID is used by clinicians and researchers worldwide.

The MID, MID Analysis, and MID Interpretive Manual are free for use by trained mental health professionals and researchers seeking to better understand dissociation and dissociative processes from the experiencer’s point of view.

If you are a person concerned that they may be dealing with complex trauma or a dissociative disorder, then please consider seeking out a professional versed in the assessment and treatment of dissociation via the International Society for the Study of Trauma and Dissociation.

MID & MID Manual

This is the Multidimensional Inventory of Dissociation, or ‘MID’. Clinical use of the MID is incomplete without conducting a thorough follow-up interview to clarify symptom features.  Used in this way, the MID can most fully support clarity in diagnosis and treatment planning.

The MID is available in two versions: Adult (appropriate for those with a 7th grade or higher reading level, and available in a variety of languages) and adolescent (which uses less formal language, but available only in English).

All documents are in .pdf format unless otherwise noted. Choose your preferred format below:

MID – Adult Version (English)

The ‘Original’ version of the current iteration of the MID first appeared in Appendix 3 of the book Rebuilding Shattered Lives, Second Edition (Chu, 2011) with an introduction that would not be necessary for a test-taker to read. It is included here for archival and informational purposes.

The ‘Reformatted’ version does not contain all of the introductory text that the ‘Original’ version does, but it still requires that the test-taker circle their responses to each question.

The MS Word version resembles the Questions tab on MID Analysis and allows for handwritten number, rather than circled, responses. This version tends to allow for easier transfer to the MID Analysis Questions worksheet. PLEASE NOTE: If you are browsing via a PC or a mobile device, you must ‘Save as…’, then open this document via MS Word (or other word processing program) to enter data, rather than simply opening it via the site and entering data directly into it. Otherwise, you risk losing the data you’ve entered.

MID – Adult Version (Non-English*)

*To date, only the English and Hebrew MIDs are validated/normed. All other versions are offered here for your convenience.

MID – Adolescent Version

Adolescent MID (English)

An Interpretive Manual for the Multidimensional Inventory of Dissociation, 3rd Edition (Released May 2020)

The Interpretive Manual, 3rd Edition, which accompanies the newly-related MID Analysis v5.0, is designed both to provide basic instructions for administering and scoring the MID and to address most questions clinicians and researchers may have about what the items, scales, etc., mean. New and seasoned professionals will benefit from reading this manual and applying informed interpretation of each client’s scores to identify which items and scales to clarify in the follow-up interview.  It is an essential resource in learning how to use the MID and MID Analysis v5.0.

Please be aware that the Interpretive Manual is a large file, so it may take a few moments to download/fully load in your browser.

MID Consultation

The MID Analysis v4.0 is a complex tool, and, although the Interpretive Manual is extensively explanatory, it can take time and practice to learn the nuances and levels of interpretation possible in using the MID.

Two of the authors of the MID Interpretive Manual, 2nd Edition, offer reasonably priced consultation on the intricacies of the MID Analysis v4.0. See below for background information for each of them before deciding whom to consult.

D. Michael Coy is a Licensed Independent Clinical Social Worker in private practice in Seattle, Washington. Michael spearheaded the overhaul of the MID Analysis from v3.8 to v4.0, and collaborated with Jennifer Madere and MID developer Paul Dell, PhD (who, along with Eli Somer, PhD, developer of the Hebrew MID, generously served as editor) on expanding the original Mini-Manual into the full Manual available elsewhere on this site. Michael has offered consultation on the use of the MID since 2015.

Michael has served clients in a variety of settings over the past thirteen years, working with homeless persons; severely abused and neglected youth and HIV+ adults in different residential treatment facilities; children, adolescents, adults, and older adults in an inpatient psychiatric facility; adults with mental health disabilities in a psychiatric nursing home; and LGBTQ adults in recovery in a community health center substance use treatment program, prior to moving into full-time private practice in 2013.

Michael’s foundational learning was in psychodynamic theory. In 2011, he trained in EMDR therapy through the EMDR Institute; he has been an EMDRIA Approved Consultant in EMDR therapy since 2015. Michael also has training in clinical hypnosis, Ego State Therapy, and Sensorimotor Psychotherapy (Level I).

Michael’s clinical practice focuses on working with people across the dissociative spectrum dealing with interwoven issues such as addictions, compulsions, and self-harming behaviors. Additionally, Michael employs an integrative treatment model to address pre-verbal and early attachment trauma in a brief intensive format.

Michael has co-presented with Jennifer Madere on the MID and its applications to clinical practice  at EMDRIA AC 2017, ISSTD AC 2018 and 2019, EMDR Canada 2018, and ISSTD’s 2019 Regional Conference in New Zealand, and has presented on his own for various groups throughout the US. Michael presented at ISSTD’s 2016 Annual Conference, along with Ulrich Lanius, PhD, and Sandra Paulsen, PhD, on the assessment and treatment of dissociative disorders. He has served as guest lecturer on EMDR therapy in 2014 and 2015 in University of Illinois at Chicago’s social work program, and presented on EMDR therapy for the Washington State Society for Clinical Social Work in 2017.

Michael has been a member of the Board of Directors for the International Society for the Study of Trauma and Dissociation (ISSTD) since January 2017, serving on the Communications & Marketing and Finance Committees, as well as chairing the Website Committee.  In 2018, Michael was appointed as interim Treasurer, and was recently elected into the position for an initial, three-year term. Michael was named a Fellow of ISSTD in 2019. Additionally, Michael created and is co-chairing a task group to develop a dissociation-sensitive EMDR therapy ‘basic’ training under the ISSTD umbrella. Michael previously served as a member of EMDRIA’s Standards & Training Committee from 2014 to 2017.

Jennifer Madere is a Licensed Professional Counselor Supervisor in private practice, and founding partner of Intuitus Group Counseling Clinic, PLLC & Independent Professionals in Cedar Park, Texas.

Having worked with child and adult survivors of trauma on their journey of healing since 2003, she worked in residential treatment, shelter, hotline, and community mental health settings before beginning private practice in 2008. As she better understood the needs of her clients, Jennifer completed EMDR therapy training in 2010, and attended the ISSTD Annual Conference for the first time in 2012.

Within her therapy and consultation practice, Jennifer began to see a need for more consistent and thorough assessment of trauma-related symptoms and client history to inform safe and effective treatment.  This led to her gathering data to compare ACES (Adverse Childhood Experiences Scale) and DES (Dissociative Experience Scale) scores, and presenting these findings at the EMDRIA Annual Conference in 2014.

Concurrently, Jennifer began using the MID in her therapy and consultation practice and teaching other clinicians to recognize and assess symptoms of pathological dissociation. From 2014-2019, Jennifer presented a workshop entitled Assessing Complex Trauma and Dissociative Disorders for EMDR Clinicians: What to do after the DES within Weekend 2 of EMDR therapy trainings offered by EMDRIA approved trainer, Rick Levinson, LCSW.

Increasingly aware of the need and appreciation for the MID by clinicians utilizing EMDR therapy, Jennifer sought and obtained permission from Paul Dell to present on the MID during the EMDRIA Annual Conference in 2015. Upon meeting D. Michael Coy immediately following that presentation, Jennifer and Michael began collaborating with Paul Dell on the writing of the 2nd Edition of the Interpretive Manual and updating the MID Analysis, initially presented in 2017 at the EMDRIA Annual Conference in Bellevue, WA. Jennifer and Michael have continued to update the MID materials and have presented internationally on the MID and related therapeutic interventions.
