Identity state-dependent self-relevance and emotional intensity ratings of words in dissociative identity disorder: A controlled longitudinal study.

Introduction: Dissociative identity disorder (DID) is characterized by, among others, amnesic episodes and the recurrence of different dissociative identity states. While consistently observed in clinical settings, to our knowledge, no controlled research study has shown the degree to which different identity states report autobiographical knowledge over time. Hence, the current study investigates self-relevance and emotional intensity ratings of words longitudinally.

Dissociative identity state-dependent working memory in dissociative identity disorder: a controlled functional magnetic resonance imaging study.

Background: Memory function is at the core of the psychopathology of dissociative identity disorder (DID), but little is known about its psychobiological correlates.

Aims: This study aims to investigate whether memory function in DID differs between dissociative identity states.

Method: Behavioural data and neural activation patterns were assessed in 92 sessions during an n-back working memory task.

The course of (comorbid) trauma-related, dissociative and personality disorders: two year follow up of the Friesland study cohort.

: There is substantial comorbidity between trauma-related disorders (TRDs), dissociative disorders (DDs) and personality disorders (PDs), especially in patients who report childhood trauma and emotional neglect. However, little is known about the course of these comorbid disorders, despite the fact that this could be of great clinical importance in guiding treatment. : This study describes the two-year course of a cohort of patients with (comorbid) TRDs, DDs and PDs and aims to identify possible predictors of course.

The Association Between Childhood Trauma and Attachment Functioning in Patients With Personality Disorders.

Attachment (mal)functioning and a history of childhood trauma (CT) are both considered psychological determinants of personality disorders (PDs). Their interaction, however, remains largely uninvestigated. In this study, the authors assessed adult and childhood attachment style in a sample of patients with diverse PDs ( = 75) and determined the relation with both occurrence and severity of CT.
