Validity and Treatment Options of Dissociative Identity Disorder

Started Mar. 20, 2026

Abstract or project description

Dissociative identity disorder (DID) is defined in the DSM-5 as a dissociative disorder where an individual presents two or more distinct personalities (also known as alters) and recurrent gaps in memory regarding everyday events, personal information, and traumatic events. DID may affect up to 1 in 100 people, and has no definite treatment. It is a heavily complex disorder that has been called a “fad” and confused with borderline personality disorder. Myths around the disorder impede the research needed for treatment. The process of diagnosing DID isn’t a steady path either. The presentation may be highly varied patient to patient, which hinders rapid diagnosis. DID has been found across many cultural backgrounds, but socio-cultural influences impact how individuals present their symptoms and what treatment is sought. Confronting patients with trauma is not always productive. Due to the inability to confront patients, combined with the discomfort to those studying DID, many researchers avoid studying this elaborate disorder. This presentation will cover the challenges that come with diagnosing DID, the socio-cultural impact on the disorder, and why DID is a valid construct. By shedding light on dissociative identity disorder, we are allowing for more treatment options, less stigma, and fewer myths surrounding the disorder.
