The present systematic review examined post-migration variables impacting upon mental health outcomes among asylum-seeking and refugee populations in Europe. It focuses on the effects of post-settlement stressors (including length of asylum process and duration of stay, residency status and social integration) and their impact upon post-traumatic stress disorder, anxiety and depression. Twenty-two studies were reviewed in this study. Length of asylum process and duration of stay was found to be the most frequently cited factor for mental health difficulties in 9 out of 22 studies. Contrary to expectation, residency or legal status was posited as a marker for other explanatory variables, including loneliness, discrimination and communication or language problems, rather than being an explanatory variable itself. However, in line with previous findings and as hypothesised in this review, there were statistically significant correlations found between family life, family separation and mental health outcomes.

Objective: This study investigated the latent dimensional and categorical structure of ICD-11 Complex Posttraumatic Stress Disorder (CPTSD) within a refugee sample. Method: A subsample that identified as refugee (n = 308) was selected from the National Epidemiological Survey on Alcohol and Related Conditions (NESARC-II). Factor Mixture Modelling (FMM) was employed to establish the dimensional structure of CPTSD symptomology and the categorical distribution of these dimensions. It was then evaluated whether trauma history could differentiate between the distribution of trauma response profiles. Results: A correlated six-factor model with five latent classes was the best fitting model. Two classes were characterised by symptom profiles that were consistent with ICD-11 CPTSD and PTSD formulations. The remaining classes were characterised by non-specific variation across dimensions. CPTSD class membership was predicted by traumas that were predominantly interpersonal in nature (serious neglect, physical assault and sexual assault) while PTSD class membership was predicted by situational traumatic experiences (unarmed civilian in a conflict environment and a serious accident). A distinct dose response effect was evident between cumulative traumatic exposure and CPTSD class membership. Conclusion: FMM class profiles distinguished between PTSD and CPTSD symptom formulations. Moreover, class membership was determined by specific trauma exposure histories.

Dissociation involves disruptions of usually integrated functions of consciousness, perception, memory, identity, and affect (e.g., depersonalization, derealization, numbing, amnesia, and analgesia). While the precise neurobiological underpinnings of dissociation remain elusive, neuroimaging studies in disorders, characterized by high dissociation (e.g., depersonalization/derealization disorder (DDD), dissociative identity disorder (DID), dissociative subtype of posttraumatic stress disorder (D-PTSD)), have provided valuable insight into brain alterations possibly underlying dissociation. Neuroimaging studies in borderline personality disorder (BPD), investigating links between altered brain function/structure and dissociation, are still relatively rare. In this article, we provide an overview of neurobiological models of dissociation, primarily based on research in DDD, DID, and D-PTSD. Based on this background, we review recent neuroimaging studies on associations between dissociation and altered brain function and structure in BPD. These studies are discussed in the context of earlier findings regarding methodological differences and limitations and concerning possible implications for future research and the clinical setting.

Introduction; There has been debate regarding whether Complex PTSD (CPTSD) is conceptually distinct from Borderline Personality Disorder (BPD). Objective: To assess whether ICD-11 CPTSD was distinguishable from BPD in a sample of sexual assault survivors. Method: A subsample of individuals (n = 956), that selected sexual assault as an index trauma, were selected from a U.S. general population survey dataset. The distribution of PTSD, CPTSD and BPD symptomology was evaluated using latent class analysis (LCA). Multinomial logistic regression analyses were performed to evaluate whether various forms of child maltreatment and cumulative child maltreatment could discriminate between classes. Results: CPTSD emerged as a distinct symptom profile within the sample. Conversely, BPD symptomology was evident in two classes but was accompanied by PTSD/CPTSD symptomology in each. Overall, five classes were identified that differed both quantitatively and qualitatively. Cumulative childhood maltreatment and physical neglect predicted CPTSD class membership. Conclusion: The findings suggest that CPTSD is distinct from BPD among a sample of individuals who have been shown to be at significant risk for both diagnoses. Further research is required to identify factors that distinguish CPTSD from BPD.
