Although it is common for patients with dissociative disorders to report a history of suicide attempts, there is very little data systematically comparing suicidality in patients with dissociative disorders versus patients without these disorders. The subjects in our study were 231 patients consecutively admitted to an inner-city, hospital-based outpatient psychiatric clinic. Eighty-two of these patients completed structured interviews for dissociative disorders, borderline personality disorder, and trauma history (dissociative disorders interview schedule) and for posttraumatic stress disorder and substance abuse (Structured Clinical Interview for DSM-IV). Patients receiving a dissociative disorder diagnosis were compared with nondissociative patients on measures of self-harm and suicidality. Presence of a dissociative disorder was strongly associated with all measures of self-harm and suicidality. When we focused on patients with a history of multiple suicide attempts, significant associations were found between several diagnoses (dissociative disorder; borderline personality disorder; posttraumatic stress disorder; alcohol abuse/dependence) and multiple suicide attempter status. When these diagnoses were entered in a logistic regression, a highly significant association remained for dissociative diagnosis and multiple suicide attempter status (odds ratio, 15.09; 95% confidence interval, 2.67-85.32; p = 0.002). Dissociative disorders are commonly overlooked in studies of suicidality, but in this population they were the strongest predictor of multiple suicide attempter status.

Dissociative disorders were highly prevalent in this clinical population and typically had not been previously diagnosed clinically. The high prevalence of dissociative disorders found in this study may be related to methodological factors (all patients were offered an interview rather than only those who had scored high on a screening self-report measure) and epidemiological factors (extremely high prevalence rates for childhood physical and sexual abuse were present in the overall study population).

Objective Posttraumatic Stress Disorder (PTSD) is prevalent among low-income minorities and is associated with poorer health. However, the association between PTSD and hemoglobin A1C (A1C) among patients with diabetes has not been fully described. The objective of this cross-sectional study was to evaluate associations between PTSD and A1C among low-income minorities with diabetes. Method Adults with diabetes were recruited from a network of primary care clinics. Data were obtained from surveys and electronic medical records. Lifetime PTSD symptoms were assessed using the Structured Clinical Interview—DSM-IV and depressive symptoms with the Patient Health Questionnaire-9. A1C was obtained from chart review. Results Of 103 adults analyzed, 12% had lifetime full PTSD and 12% had subthreshold PTSD. On backward stepwise logistic regression, patients with any PTSD symptoms were significantly more likely to have an A1C >7% compared to patients without symptoms (ORadj 2.98, 95% CI 1.04–8.52, P=.04). An A1C >7% also was associated with an interaction between PTSD symptoms and longer diabetes duration (P<.05). Conclusion In this cohort of low-income minorities with diabetes, lifetime PTSD symptoms were significantly associated with an A1C >7%.

Schizophrenia and dissociative identity disorder (DID) are typically thought of as unrelated syndromes--a genetically based psychotic disorder versus a trauma-based dissociative disorder--and are categorized as such by the DSM-IV. However, substantial data exist to document the elevated occurrence of psychotic symptoms in DID; awareness of these features is necessary to prevent diagnostic confusion. Recent research has also pointed out that schizophrenia and DID overlap not only in psychotic symptoms but also in terms of traumatic antecedents, leading to a number of suggestions for revision of our clinical, theoretical, and nosologic understanding of the relationship between these two disorders.

Dialectical Behavior Therapy, created by Marsha Linehan, has been shown to be an effective therapy for the treatment of borderline personality disorder (BPD) and for suicidal and self-harming behavior. Dissociative identity disorder (DID) is a complex post-traumatic disorder which is highly comorbid with BPD, shares a number of clinical features with BPD, and which like BPD features a high degree of suicidality. The DID treatment literature emphasizes the importance of a staged approach, beginning with the creation of a safe therapeutic frame prior to addressing traumatic material; DBT is also a staged treatment, where behavioral and safety issues are addressed in Stage 1 and trauma work reserved for Stage 2. The authors describe adapting DBT, and especially its techniques for Stage 1 safety work, for work with DID patients. Basic theoretical principles are described and illustrated with a case example.
