EXPLOration of Processes Involved in Dissociative Identity Disorder (DID)

Dissociative Identity Disorder (DID)

Dissociative Identity Disorder

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

This study falls within the field of dissociative disorders, and more specifically dissociative identity disorder (DID), whose clinical validity and mechanisms remain controversial, particularly due to the reported frequency of feigned symptoms. Objective The primary objective is to identify the functional determinants of episodes of personality state change, whether genuine or feigned, within the framework of cognitive-behavioral therapies (CBT). The analysis is based on the SORC functional model: * S (Stimuli): triggering situations * O (Organism): cognitions, emotions, sensations, imagery * R (Response): operant behaviors * C (Consequences): short- and long-term effects Methodology An exploratory qualitative approach will be used, aimed at generating hypotheses for subsequent quantitative research. Participants * N ≈ 60 * 30 diagnosed with TDI * 30 simulated TDI * Multicenter recruitment * Inclusion: ≥ 18 years old, currently undergoing therapy Procedure Participants will complete: * sociodemographic questionnaires * standardized scales: * dissociation (sDIS-Q) * dissociative beliefs (DSB) * knowledge about dissociation (KADS) * post-traumatic symptoms Then, a semi-structured qualitative interview will be conducted and recorded. Analysis * Thematic analysis of interviews * Data saturation approach * Cross-coding by raters Scientific objectives * Clarify the mechanisms of TDI * Identify functional patterns of dissociative episodes * Explore differences between genuine and feigned symptoms * Improve diagnostic validity and therapeutic interventions
