MID-60
Multidimensional Inventory of Dissociation (MID-60)
The MID-60 is a self-report questionnaire for screening dissociative symptoms in adults aged 18 and over. Developed in 2020 from the full 218-item version of the MID, it comprises 60 questions and 12 subscales covering, in particular, dissociative amnesia, derealization/depersonalization, ego-state intrusions, flashbacks, trance, certain somatic symptoms, and identity confusion. It is designed to identify presentations consistent with the DSM-5-TR dissociative disorders, as well as associated phenomena such as certain symptoms of PTSD or functional neurological symptom disorder.

Scoring & interpretation
Each item is rated from 0 to 10 according to the frequency of the reported experience. The total score is the mean of the 60 responses multiplied by 10, giving a result from 0 to 100, interpreted as the approximate percentage of time during which the person reports dissociative experiences. The 12 subscales are examined separately and are considered clinically elevated when their mean score reaches or exceeds their clinical cutoff. For the total score, the suggested benchmarks are: 0–6 no dissociative experiences, 7–14 few clinically significant experiences, 15–20 mild symptoms, 21–30 possible dissociative disorder and/or PTSD, 31–40 probable dissociative disorder, 41–63 probable DID or severe dissociative disorder, 64–79 severe symptoms, 80+ exceptionally high score. Any elevation must be interpreted using clinical judgment and, if necessary, supplemented by a structured interview.
