The Multidimensional Inventory of Dissociation (MID)

The Multidimensional Inventory of Dissociation (MID) is a widely used self-report measure that assesses dissociative experiences. The MID is a 60-item questionnaire that is designed to measure the severity of dissociative symptoms and experiences in adults. The MID is available in both a 60-item version (MID-60) and a 100-item version (MID-100). The MID-60 is a shorter version of the MID-100 and is often used in clinical settings.

Introduction

The Multidimensional Inventory of Dissociation (MID) is a comprehensive assessment tool designed to evaluate the presence and severity of dissociative experiences in individuals. Developed by Dr. Onno van der Hart and colleagues, the MID assesses dissociative symptoms and experiences that are consistent with the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). The MID is a self-report measure, meaning that individuals complete the questionnaire themselves, providing insights into their own subjective experiences. The MID is a valuable tool for mental health professionals in the diagnosis and treatment of dissociative disorders, including Dissociative Identity Disorder (DID), Depersonalization/Derealization Disorder, and Post-Traumatic Stress Disorder (PTSD).

The MID is a psychometrically sound instrument, meaning that it has been rigorously tested and validated to ensure its reliability and accuracy. The MID has demonstrated strong internal consistency and test-retest reliability, indicating that it consistently measures the same construct over time. Additionally, the MID has been found to be sensitive to change, meaning that it can detect improvements in dissociative symptoms following treatment. The MID is a widely used and respected tool in the field of mental health, and its use has contributed to a greater understanding of dissociative disorders and their treatment.

The MID-60

The MID-60 is a 60-item version of the Multidimensional Inventory of Dissociation (MID), a self-report questionnaire designed to assess dissociative experiences in adults. The MID-60 is a shorter and more efficient version of the original 100-item MID, making it a practical choice for clinical settings where time constraints may be a factor. Despite its shorter length, the MID-60 maintains the comprehensive nature of the original MID, covering a wide range of dissociative symptoms and experiences. These include amnesia, depersonalization, derealization, identity confusion, and altered states of consciousness.

The MID-60 utilizes an 11-point Likert scale format, ranging from “Never” to “Always,” allowing individuals to rate the frequency of their dissociative experiences. The MID-60 can be administered and scored using a variety of methods, including paper-and-pencil, computer-based, or online platforms. The scoring process involves calculating a total score based on the individual’s responses to each item. This total score provides a quantitative measure of the severity of dissociative experiences. The MID-60 has been shown to be a reliable and valid instrument, demonstrating good internal consistency and test-retest reliability, and is widely used in clinical practice for the assessment and diagnosis of dissociative disorders.

Scoring the MID

Scoring the MID involves a straightforward process, typically utilizing an Excel-based scoring program. Each item on the MID-60 is rated on an 11-point Likert scale, ranging from “Never” to “Always;” The responses are then converted into numerical values, with higher scores indicating greater severity of dissociative experiences. The scoring program calculates a total score by summing the numerical values assigned to each item.

The total score is then interpreted as a percentage, representing the percentage of time the individual experiences dissociative symptoms. For example, a total score of 50 would indicate that the individual experiences dissociative symptoms 50% of the time. The MID also generates scale scores for various dissociative subtypes, such as amnesia, depersonalization, and identity confusion. These scale scores provide a more detailed understanding of the specific types of dissociative experiences an individual is experiencing. The MID’s scoring system is designed to be user-friendly and accessible, allowing clinicians to quickly and efficiently obtain valuable information about an individual’s dissociative experiences.

Uses of the MID

The MID-60 is a versatile assessment tool with broad applications in various clinical settings. Its primary use is in the diagnosis and assessment of dissociative disorders, including Dissociative Identity Disorder (DID), Dissociative Disorder Not Otherwise Specified (DDNOS), and Post-Traumatic Stress Disorder (PTSD). The MID-60’s ability to measure different aspects of dissociation allows clinicians to identify the specific dissociative experiences an individual is having, which is crucial for developing tailored treatment plans.

Beyond diagnosis, the MID-60 is also employed to monitor treatment progress and assess the effectiveness of interventions. By administering the MID-60 at different points during treatment, clinicians can track changes in dissociative symptoms and tailor their therapeutic approach accordingly. Furthermore, the MID-60 can be used in research studies to investigate the prevalence and characteristics of dissociative disorders in various populations. Its ability to provide a comprehensive assessment of dissociative experiences makes it an invaluable tool for researchers seeking to understand the complexities of these disorders.

Interpretation of the MID

The interpretation of the MID-60 involves a multi-faceted approach, considering both quantitative and qualitative aspects of the assessment. The total score, which ranges from 0 to 100, reflects the overall level of dissociative experiences. A higher score indicates a greater severity of dissociative symptoms. However, it is essential to go beyond the total score and analyze the individual subscale scores. The MID-60 encompasses four subscales⁚ Amnesia, Depersonalization/Derealization, Identity Alteration, and Identity Confusion.

Analyzing the subscale scores provides insights into the specific types of dissociative experiences an individual is experiencing. For instance, a high score on the Amnesia subscale suggests significant memory problems, while a high score on the Identity Alteration subscale indicates a more pronounced sense of fragmented identity. Furthermore, the MID-60 includes specific items related to trauma history, which can aid in understanding the potential relationship between trauma and dissociative experiences.

The MID in Clinical Practice

The MID-60 plays a crucial role in clinical practice, particularly in the assessment and diagnosis of dissociative disorders. It serves as a valuable tool for mental health professionals in identifying individuals who may be experiencing significant dissociative symptoms. The MID-60 can be administered as part of a comprehensive psychological evaluation to gain a deeper understanding of the client’s dissociative experiences. The results can guide treatment planning, allowing clinicians to tailor interventions to address specific dissociative symptoms.

Furthermore, the MID-60 can assist in monitoring treatment progress. By administering the assessment at different points during therapy, clinicians can track changes in dissociative symptoms over time. This information can help determine the effectiveness of treatment and guide adjustments as needed. The MID-60’s utility extends to research, where it is frequently employed to study the prevalence and characteristics of dissociative disorders, as well as to evaluate the efficacy of various treatment approaches.

Advantages and Limitations of the MID

The MID-60 offers several advantages as a screening tool for dissociative disorders. It is a relatively brief and straightforward assessment, making it feasible to administer in clinical settings. The MID-60 has demonstrated good reliability and validity, meaning that it consistently measures what it is intended to measure. Additionally, the MID-60 is available in multiple languages, enhancing its accessibility to a wider range of individuals.

However, it is important to acknowledge the limitations of the MID-60. Like any self-report measure, it is susceptible to biases, such as social desirability, where individuals may present themselves in a more favorable light. The MID-60 also does not directly assess all aspects of dissociative disorders, and it is crucial to consider other diagnostic criteria and clinical information when making a diagnosis. Furthermore, the MID-60 should not be interpreted in isolation; it is essential to incorporate clinical judgment and other assessment tools to obtain a comprehensive understanding of the individual’s dissociative experiences.
