The role of childhood and adulthood trauma and appraisal of self-discrepancy in overgeneral memory retrieval

A Systematic Review of Autobiographical Memory and Mental Health Research on Refugees and Asylum Seekers

Research examining trauma, memory, and mental health among refugee and asylum-seeking people has increased in recent years. We systematically reviewed empirical work focusing on the link between autobiographical memory and mental health among these populations. The review protocol was registered with PROSPERO (CRD42018095888). Six major databases were searched in August-2020 with no time limit for publication. Following PRISMA Statement guidelines, 22 articles reporting ten quantitative, nine qualitative, and three mixed-method studies were selected from 254 articles identified in the initial search. A basic convergent and qualitative meta-integration technique was employed for data extraction. Four recurrent themes were extracted: (1) memory activation method, (2) memory features, (3) memory content, and (4) refugee mental health. Theme 1 illustrates that narrative interviews, important event recall, and cue word methods were used in most studies. Theme 2 highlights that memories of refugee people were often less specific, inconsistent, and negative-focused. Retrieval failure was also common among these people. Theme 3 reveals that refugee and asylum-seeking people frequently discussed their abandoned identities, lost resources, injustices, ongoing sufferings, and pointless futures. Finally, theme 4 identifies the prevalence of various mental health conditions like Post-traumatic Stress Disorder, depression, helplessness, and anger among these people. The results are discussed in the context of the current autobiographical memory and mental health theories, considering refugee-specific experiences in the asylum process and refugee status.

Meta-Analysis of the Association Between Autobiographical Memory Specificity and Exposure to Trauma

Cognitive models of emotional disorders suggest that reduced autobiographical memory specificity that results from exposure to traumatic events may play an important role in the aetiology and maintenance of these disorders. However, there has yet to be a comprehensive meta-analysis of the association between trauma exposure and memory specificity, and the role of posttraumatic stress symptoms on this association. We searched PsycINFO and MEDLINE databases and extracted data from studies regarding the mean number or proportion of specific memories that participants with and without trauma exposure recalled on the Autobiographical Memory Test. We also extracted data on differences between groups in terms of posttraumatic stress and depressive symptoms, along with data on trauma timing and participants' ages at the time of assessment. The effect size of memory specificity between participants with and without exposure to trauma was large, d = 0.77, and differed significantly from zero, p < .001. In metaregression, trauma timing was a significant predictor of the heterogeneity in trauma-exposure specificity effect sizes, but posttraumatic stress and depressive symptoms were not. Compromised memory specificity represents an important cognitive consequence of trauma exposure that might have an important influence on risk for, and maintenance of, subsequent emotional pathologies.
