Summary: This study analyzed 343 female patients with substance use disorder (SUD) and posttraumatic stress disorder (PTSD), and found that childhood trauma is associated with suicidal behaviors, with dissociation mediating the relationship between childhood sexual abuse and suicidal behavior. These findings highlight the importance of addressing dissociative symptoms and the complex consequences of childhood trauma in the treatment of SUD patients.

Summary: This study found that traumatic experiences are associated with an increased risk of psychotic experiences, and PTSD symptoms may mediate this relationship. Targeting PTSD symptoms might help prevent the onset of psychotic outcomes.

Summary: This study aimed to explore the relationship between baseline self-stigma and dissociative, PTSD, and depressive symptoms. The findings showed that self-stigma was associated with post-intervention PTSD and depressive symptoms, but not with dissociative symptoms. These preliminary findings call for more efforts in understanding, preventing, and addressing self-stigma in people with trauma-related mental health issues such as dissociative symptoms.

Summary: This study explored the experiences of patients and therapists with trauma-focused treatments for childhood trauma-related posttraumatic stress disorder. Findings suggest the importance of patient engagement and commitment, the challenges of trauma work, and the impact of therapy on insight, self-perception, and empowerment. Therapists also provided suggestions for optimizing their role in trauma-focused treatment, emphasizing the importance of confidence, addressing avoidance behaviors, and adhering to treatment protocols.

Summary: This study used data from a longitudinal cohort to examine the effects of early childhood adversity on transitions into alcohol and cannabis co-use trajectories among young adults. The study found that individuals who experienced high levels of childhood adversity were more likely to transition into chronic and rapidly increasing co-use trajectories. Male individuals who experienced high levels of childhood adversity were also more likely to meet clinical cutoff for depression.

Summary: There is robust evidence linking dissociation to psychotic positive symptoms, but the specific contribution of different dissociative phenomena is still unknown. This study found that derealization/depersonalization combined with amnesia accounted for a significant portion of the variance in the psychoticism subscale, and absorption combined with emotional abuse accounted for a significant portion of the variance in the paranoid ideation subscale.

Summary: An increasing number of studies suggest that dissociative and psychotic symptoms are common in Post Traumatic Stress Disorder (PTSD) and may be directly caused by trauma. This presentation aims to present the characteristics of dissociation and hallucinations in the context of PTSD, using a clinical vignette to illustrate the intertwining of PTSD symptomatology and psychotic symptoms.

Summary: The study found that self-reported peritraumatic dissociation is not temporally stable, and there is a significant association between current PTSD symptom levels and peritraumatic dissociation scores.

Summary: This study found that identification with the aggressor, PTSD symptoms, and dissociation are associated with suicidal ideation and behavior among childhood abuse survivors, with individuals characterized by high levels of identification with the aggressor, PTSD symptoms, and dissociation being at higher risk for suicide and suicide attempts.

Summary: This study investigated the importance of peritraumatic reactions in the etiology of PTSD, finding that mental defeat and somatoform dissociation significantly predicted all PTSD symptom clusters. Other factors such as cognitive overload, immobility, and distress had varying effects on different symptom clusters. This research is likely to benefit the study of etiological mechanisms, risk prediction, and design of prevention interventions related to PTSD.

Summary: Complex post-traumatic stress disorder (CPTSD) has been recognized as a psychiatric diagnosis with dissociative symptoms as a major feature. This scoping review aims to summarize existing knowledge on the relationship between dissociation and CPTSD, and identify research gaps. Studies show that people with CPTSD have higher dissociation scores and a positive correlation between CPTSD symptoms and dissociation scores. Further research is needed to investigate the prevalence, correlates, and clinical needs of dissociative symptoms in this vulnerable group.

Summary: Nearly a quarter of Canadian public safety personnel in the sample reported experiencing elevated levels of PTSD-related dissociation (depersonalization and derealization). These high levels of depersonalization and derealization were consistently positively associated with greater illness severity across clinical measures. It is crucial to better recognize dissociative symptoms in patient populations exposed to chronic traumatic events like PSP to design treatment interventions targeting a more severe illness presentation.

Summary: This study examined the presence of adverse events in individuals with Bipolar Disorder (BD) during childhood and adulthood, as well as the prevalence of PTSD. The results showed that individuals with BD had significantly higher scores of childhood and lifetime adversities compared to controls, and a significantly higher prevalence of probable PTSD as well. Limitations of the study include possible recall bias and missing data.

Summary: This study compared visual phenomena and dissociation in participants with a primary psychotic illness and those with a trauma diagnosis. The results showed remarkable similarities in visual experiences among the three diagnostic groups, including complex visual hallucinations, with no significant differences in severity or distress components surrounding the visual experiences. Dissociation predicted visual hallucination severity in the comorbid schizophrenia and PTSD group.

Summary: This study reveals the characteristics of psychological trauma in patients with bipolar disorder, as well as the differences in trauma symptoms between BD-I and BD-II. PTSD diagnosis is associated with psychotic symptoms, while sexual abuse is associated with rapid cycling. There is no significant difference in BD severity between PTSD and subsyndromal trauma symptoms. These findings highlight the importance of screening for trauma in patients with bipolar disorder.
