About this trial
Dissociative Identity Disorder (DID) is a psychological condition in which a person may feel as though they have multiple distinct personalities or identities. Today, this disorder is being discussed more and more, particularly among young people, partly due to its visibility on social media. However, researchers have observed that some individuals may mimic or exaggerate the symptoms, which makes it more difficult to understand the disorder.
The goal of this study is therefore to better understand:
* in which situations these identity shifts occur * what people feel at that moment * and what happens next To do this, researchers will interview approximately 60 people, some with a diagnosed DID and others exhibiting simulated symptoms.
Participants will complete questionnaires and take part in an interview. The researchers will analyze:
* the situations that trigger the changes * the associated thoughts and emotions * the behaviors * the consequences of these episodes
The ultimate goal is to better understand this disorder in order to:
* improve care * and better distinguish between genuine cases and feigned ones
