A nurse is preparing an in-service for a group of staff members about dissociative identity disorder. Which of the following should the nurse identify as a risk factor for this disorder?

A. A history of self-injurious behavior. While self-injurious behavior can be associated with various mental health conditions, it is not specifically identified as a risk factor for dissociative identity disorder (DID). B. A history of schizophrenia. Schizophrenia is a distinct mental health disorder characterized by psychotic symptoms, and while individuals with schizophrenia may experience dissociation, it is not considered a direct risk factor for DID. C. Borderline personality disorder. While there is some overlap between symptoms of borderline personality disorder and dissociative symptoms, having borderline personality disorder itself is not a primary risk factor for developing DID. D. History of trauma during the developmental years. A significant risk factor for dissociative identity disorder is a history of severe trauma or abuse during childhood, particularly chronic emotional, physical, or sexual abuse. This trauma can disrupt normal psychological development and contribute to the fragmentation of identity characteristic of DID.
