Deenz Dissociative Identity Inventory (DII-28)

Dissociative identity test/quiz is a digital adaptation of the Dissociative Identity Inventory (DII-28). Dissociative Identity Disorder (DID), previously known as Multiple Personality Disorder, is a complex mental health condition characterized by the presence of two or more distinct identity states. These identity states may influence behavior, memory, emotions, and awareness.

Researchers increasingly emphasize understanding dissociative experiences on a spectrum rather than viewing them as a single phenomenon. Dissociation can involve disruptions in memory, identity, perception, emotional regulation, and awareness. The Deenz Dissociative Identity Inventory was developed to measure tendencies associated with dissociative experiences across multiple dimensions.

The scale evaluates seven important facets commonly associated with dissociative experiences: Amnesia, Dissociation, Alters, Identity Confusion, Flashbacks, Depersonalization, and Mood Instability. Measuring these dimensions individually provides a more detailed understanding of dissociative tendencies and their potential impact on daily functioning.

The assessment consists of 28 statements and generally requires 5–8 minutes to complete. Participants respond to statements describing memory experiences, identity-related experiences, emotional states, dissociative symptoms, and behavioral tendencies.

This assessment is intended for educational and self-reflection purposes. Participation is anonymous and no personally identifying information is collected or stored.

The assessment contains 28 items scored on a five-point agreement scale. Responses are summed to calculate both an overall score and seven dimension scores.

The total score ranges from 0 to 112, with higher scores indicating stronger dissociative identity-related tendencies.

Results include an Overall Index Score and scores for:

• Amnesia
• Dissociation
• Alters
• Identity Confusion
• Flashbacks
• Depersonalization
• Mood Instability
