Revisiting False-Positive and Imitated Dissociative Identity Disorder

Area of Science:

• Psychiatry
• Clinical Psychology
• Psychopathology

Background:

• Current diagnostic guidelines in ICD-10 and DSM-5 lack clarity for diagnosing Dissociative Identity Disorder (DID).
• This ambiguity complicates the differentiation between genuine DID and imitated or false-positive presentations.
• Understanding patient perspectives is crucial for refining diagnostic accuracy.

Purpose of the Study:

• To explore the meanings attributed to a Dissociative Identity Disorder (DID) diagnosis by patients whose diagnosis was ultimately disconfirmed.
• To investigate the patient experience of receiving and subsequently having a DID diagnosis invalidated.
• To identify themes related to the endorsement, justification, and impact of a DID diagnosis.

Main Methods:

• A qualitative study involving interpretative phenomenological analysis (IPA) of transcribed interviews.
• Participants included six women whose prior DID diagnosis was disconfirmed after clinical assessment.
• Initial screening involved 85 individuals with elevated dissociative symptoms (SDQ-20), followed by clinical assessment (Trauma and Dissociation Symptoms Interview) and psychiatric interviews.

Main Results:

• Five key themes emerged: diagnosis endorsement/identification, justification of identity confusion by dissociative parts, influence of DID knowledge on presentation, fragmented personality as a discussion topic, and disappointment/anger upon ruling out DID.
• Patients may actively engage with and derive meaning from a DID diagnosis, even if later invalidated.
• The process of diagnosis and its subsequent removal significantly impacts patient experience and self-perception.

Conclusions:

• Clinicians require enhanced, systematic training in assessing dissociative disorders to discern subtle symptom differences.
• Improved diagnostic training can lead to a better understanding of how patients with and without DID report core dissociative symptoms.
• Guidelines for differential diagnosis are proposed to mitigate misdiagnoses and improve patient care.
