| Purpose | Diagnostic method |
The Multiscale Dissociation Inventory (MDI) is a comprehensive, self-administered, multiscale instrument developed by Paul F. Dell.[1] It is designed to assess the entire domain of dissociative phenomena.[2] The MDI measures 14 major facets of pathological dissociation and uses 23 scales to diagnose dissociative disorders.[1]Cite error: A <ref> tag is missing the closing </ref> (see the help page).[2][3] Thus, an individual may show dissociative symptoms by displaying no reaction to the death of a valued loved one, by noting that life feels unreal, by disowning all or part of the body, or by claiming amnesia for an important event or an aspect of life.[2][4]
Assessment
The MDI was designed for clinical research and for diagnostic assessment of patients who present with a mixture of dissociative, posttraumatic, and borderline symptoms.[1][5] The MDI demonstrated internal reliability, temporal stability, convergent validity, discriminant validity, and construct validity.[5]Cite error: A <ref> tag is missing the closing </ref> (see the help page).
In a study examining the 30-item Multiscale Dissociation Inventory (MDI) in two groups of individuals with trauma exposure, the MDI showed excellent internal consistency and demonstrated strong evidence of both convergent and discriminant validity.[5] The findings of this study supported the existing 5-factor structure of the MDI, which includes Disengagement, Identity Dissociation, Emotional Constriction, Memory Disturbance, and Depersonalization/Derealization. Additionally, the study identified one specific factor (Memory Disturbance) and several individual items that could benefit from additional validation, refinement and improvement in subsequent studies.[5][6]
The inclusion of the Multiscale Dissociation Inventory (MDI) in clinical practice is highly recommended, particularly when working with client populations that are known to be vulnerable to complex trauma.[1] Accurately assessing dissociative symptoms in individuals who have experienced trauma is crucial for comprehending the connection between dissociation and trauma, as well as for developing effective treatments for posttraumatic dissociation.[5][7][3]
