Abstract
Introduction:
Migration is often accompanied by interpersonal, material and abstract losses and can be associated with migratory grief. The correlates of migratory grief have not yet been sufficiently addressed in research. This review aims to systematically investigate the relationship between migratory grief and psychopathology, to map the current state of research on this highly relevant topic and to derive relevant implications for the target group.
Method:
A systematic literature search of electronic databases (PubMed/Medline, PsycINFO, Web of Science) was conducted up until January 2023. Primary empirical quantitative and qualitative studies with migrants were included that assessed the association between migratory grief and psychopathology, using a specific instrument for migratory grief (quantitative) or named migratory grief as relevant topic (qualitative). Studies that only captured aspects of migratory grief, were not written in English, or were descriptive/non-peer-reviewed publications, were excluded. A quality assessment of all studies included was performed using the Mixed Methods Appraisal Tool. The results were synthesized using a narrative synthesis approach.
Results:
All studies (quan. = 4; qual. = 1) were cross-sectional and used convenience samples. The studies had a mean number of 83 participants with a total of N = 487 participants included in the current review. All included studies reported a significant relationship between migratory grief and psychological distress.
Discussion:
Despite the quality of the included studies being limited, our results show that there is a link between migratory grief and depression among refugees and migrants. However, there are only few studies in this currently and certainly also in the future relevant field of research, which is why further studies on factors influencing migratory grief as well as associations with other disorders would be desirable.

1 Introduction
Grief is commonly defined as a natural reaction to loss, which becomes less intense over time and enables adaptation to a new reality (, ). However, certain circumstances and factors can lead to associated mental disorders such as persistent grief disorder, depression, anxiety or PTSD (, ). Migration takes relevance in this context, as migrants1 often experience reactions of grief due to the occurrence of traumatic events and losses. While reasons for migration can be diverse, e.g., the search for protection, saving of lives or opening the access to new opportunities, implications may be devastating (–). Migrants can suffer a number of losses that are clearly related to the migration experience. In the following, we refer to these losses as “migration-related losses”. These losses may include the loss of relatives and friends (interpersonal losses), of house and income (material losses) but also of status, social role, identity, communication possibilities due to a new language, of a planned future and dreams or simply of the familiar surroundings (abstract losses) (, ). Although losses are such a common and presumably consequential sequel of migration, they receive little attention in research. This applies particularly to abstract losses that are often not socially recognized (–). Eisenbruch () named the distress occurring after loss of homeland, identity and social connectedness due to relocation “cultural bereavement”. Achotegui () developed the concept of the “Ulysses syndrome” to depathologize the feelings of alienation and stress after migration. Nevertheless, we know that the migration experience is associated with increased prevalence of mental distress. A Meta-analysis by Lindert et al. () show prevalence rates of 20% for depression among labor migrants and 44% among refugees as well as 21% for anxiety among labor migrants and 40% among refugees. According to a systematic review by Kokou-Kpolou et al. (), the pooled prevalence of prolonged grief disorder was 33.2% in adult refugees. A number of risk factors for the mental health of migrants have already been investigated, such as gender, income, language skills, social support and social isolation, discrimination (e.g. regarding housing or employment) and legal status (–). It is also discussed that vulnerabilities often do not result from independent risk factors, but from intersectional inequalities based on gender, age, race, ethnicity, social class and legal status (, ). Although a number of risk factors for migrants’ mental health are associated with various dimensions of loss (), the processing of loss, i.e. grief, is rarely the focus of research. In addition, since both migration and grief seem to be risk factors for mental disorders, the question arises as to why there is so little research on the specific combination of these two factors and their implications for the mental health of migrants. Therefore, we have set the aim for this review to systematically investigate the relationship between MG and psychopathology (PP) in migrants to clarify its relationship, identify possible research gaps and derive clinical implications.
2 Methods
The systematic review was conducted and reported following the PRISMA Statement to the best of ability (). It was registered with PROSPERO (CRD42023403448).
2.1 Search strategy
A systematic literature search of electronic databases (PubMed/Medline, PsycINFO, Web of Science) was conducted without time or language restrictions to identify relevant studies (final search date: 30/01/23). The search term focused on the link between MG and PP: [(psychopathol* OR depression OR psychiatr* OR depressiv* OR “posttraumatic stress” OR “psychological distress” OR “mental health”) AND (displacement OR migratory OR migration OR refugee OR “asylum seeker”) AND (grief OR loss OR mourn* OR “bereavement”)] NOT (cell migration OR erythema). The „snowball-method” was used to identify additional studies, since a hybrid search strategy increases the probability of identifying all relevant studies (). Citavi 6 was used to catalogue all identified records and remove duplicates. Two authors (AR and VS) screened abstracts independently. After calculation of agreement and discussion with Supervisor AK regarding inconsistencies in inclusion, AR conducted the full text screening for inclusion or exclusion. VS assisted with full text analysis for individual studies where ambiguity was prevalent. Disagreements were resolved by discussion with AK. Using Cohen`s Kappa statistic, κ (), inter-rater reliability was assessed and equalled 0.929.
2.2 Eligibility criteria
Primary empirical quantitative and qualitative studies were included in this review. No time limit was set regarding the publication year of the studies up until the latest search in January 2023. Inclusion criteria were: (1) Participants: Persons of all genders and ages that were exposed to any kind of migration experience (e.g. labor migration, internal displacement, refugees). (2) Exposure: In the included quantitative studies, MG had to be assessed with a specific instrument. In qualitative studies, MG had to be named as such or as a synonym (i.e. cultural bereavement, “Ulysses-syndrome”), (3) Outcomes: The association between MG and PP had to be reported. Excluded were studies that (1) only captured aspects of MG (e.g. interpersonal losses only), (2) were not written in English, (3) were case studies, reviews, descriptive studies, expert opinions, clinical guidelines, conference papers or non-peer-reviewed publications.
2.3 Data collection and analysis
When studies met inclusion criteria, the following data was double extracted independently by AR and VS from quantitative studies: (1) Source: author, publication, year, country, journal; (2) Sample: type of sample, sample size, recruitment; (3) Measurements of MG and PP; (4) methods; (5) Outcomes: Correlation coefficients between MG and Psychopathology were extracted from each included study. Bullet points 1-2 were also collected in qualitative studies, in addition to reports on the occurrence of MG in the population and mention of the association with psychological distress.
Results were synthesized narratively and additionally summarized in a table for better overview. Due to the low number of quantitative studies and the heterogeneity in measurement instruments, no meta-analysis was performed.
2.4 Quality assessment
The Mixed Methods Appraisal Tool (MMAT) () was applied to appraise the quality of quantitative and qualitative studies independently by two researchers. The MMAT was chosen for its acknowledged reliability in evaluating mixed methods research (). It is essential to highlight that the MMAT does not primarily assess the overall ‘quality’ of a research paper. Rather, it is employed to ascertain whether a study’s methodology meets predefined criteria indicative of methodological quality. Ratings depend on fulfilling criteria, with variations based on the study type. A score of 1 is assigned for each fulfilled criterion, allowing for a maximum total of 4 for each study. If criteria are unmet or information is absent in the study, a score of 0 is assigned. AR and VS independently performed a quality assessment of included studies; disagreements were resolved by discussion with AK. A detailed description of the MMAT rating criteria and the categorization of the included studies can be found in Appendix 1.1.
3 Results
The systematic search yielded a total of 2505 results. After removal of duplicates, 1585 records remained for abstract screening. Of those, 54 records were found suitable for full-text screening and five were included in the current review (4 quantitative and 1 qualitative study). The selection process is pictured in Figure 1.

4 Discussion
4.1 Summary of key findings
Migration is a global phenomenon as old as human history and its relevance continues to increase due to ongoing conflicts as well as climate change and its consequences (
4.2 Research gaps and potential for future research
Although various losses are discussed in the migration and mental health literature (
4.3 Implications
In addition to the identification of necessary research in the field of MG, practical implications can also be derived from the results of the present review. Unfavorable environmental factors can complicate grieving processes and thus make the development of mental disorders more likely (
4.4 Limitations
The results of this review were subject to some limitations that should be considered. On eligibility, the quality of the included studies is limited. All studies used a snowball- or convenience-sampling method, hence the participants are not representative of the target population. Not all studies reported inclusion- and exclusion criteria clearly. In one study, a MG measure was adapted without testing validity and reliability. Studies were not comprehensively controlled for confounders. Especially structural factors and their interaction, such as legal status and various facets of discrimination might complicate mourning processes and should therefore be analyzed as influencing factors on MG and its association with PP. Further, no cut-offs of MG were reported, therefore it was not possible to assess at which point MG values are considered high. Although it can be assumed that MG changes in the course of the stay in the country of arrival (
5 Conclusion
This review provides evidence that there is a link between MG and PP among refugees and migrants. However, there are only a few studies in this field of research, which is currently relevant and will presumably be of great relevance in the future, which is why further studies on factors influencing MG as well as correlations with other disorders would be desirable.
