Abstract
Forced migrants are at an increased risk of mental disorder compared to host country populations. To effectively address this, programmatic and policy responses need to be underpinned by rigorous evidence. Drawing on our experience conducting a systematic review of post-migration risk factors for mental disorder among asylum seekers and our appraisal of related systematic reviews, this paper discusses four challenges facing the field:
The reliance on Western conceptions of mental health.
The investigation, to date, of a relatively narrow range of potential risk factors.
The lack of consistency in the measurement and reporting of risk factor variables.
The use of the legal term ‘asylum seeker’ to define study populations.
We suggest potential ways forward, including using mental health measures developed in collaboration with communities affected by forced migration, the examination of key risk factors around homelessness and workers' rights, the development of a core set of risk factors to be investigated in each study, and defining study populations using the conceptual category of ‘sanctuary seekers’ – people who have fled their country and are asking another country for safety and residence.
Key words: Mental health, minority issues and cross-cultural psychiatry, risk factors, social and political issues
Introduction
The number of forced migrants across the world has risen sharply since 2007 (UNHCR, 2019): Historically, low and middle income countries such as Uganda, Turkey, Jordan, Lebanon, Pakistan and Iran have hosted the highest number of refugees in the world (UNHCR, 2014). The US being the main exception. More recently, Western countries (i.e. high-income, majority white nations) such as Sweden and Germany are accommodating increasing numbers of people (UNHCR, 2019). Forced migrants in both Western and non-Western countries are likely to have a higher risk of mental disorder compared to the host country population (Ryan et al., 2009). This is linked to stressors experienced pre-migration, during journeys, and post-migration (Zimmerman et al., 2011).
Programmatic and policy responses addressing the mental health of forced migrants should be underpinned by rigorous evidence. Yet, academic evidence on asylum and mental health is fragmented and siloed. This paper examines the issues with the evidence base used by Western practitioners, offering suggestions on how to move forward. We identify four key challenges in Western forced migration research, arguing that:
The reliance on Western conceptions of mental health makes it difficult to learn from the example of other countries and cultures.
The investigation, to date, of a relatively narrow range of potential risk and protective factors limits the evidence base.
The lack of consistency in the measurement and reporting of risk factor variables makes it difficult to synthesise evidence.
The use of the legal term ‘asylum seeker’ to define study populations makes it harder to draw on relevant evidence from migrants in other legal categories across the world.
We address each point using statistics and reflections from our systematic review of social environmental risk factors for mental disorder in people seeking asylum (Jannesari et al., 2020). Descriptive statistics on risk factors, outcome measures and population are drawn from review results, appendices and preparatory work. Some statistics have been updated to include papers that were eligible for our review but could not be included in the synthesis due to a lack of outcome data. Our points are further informed by the appraisal of other reviews in the field (Patel, 2011; Ryan et al., 2009).
The reliance on Western conceptions of mental health
In our review's (Jannesari et al., 2020) updated statistics, most studies looked depression (39 of 49), followed by PTSD (38) and anxiety (29). Measurement tools were primarily developed by US universities, including the most common ones for depression and anxiety, the HSCL-25 (used by 21 and 18 studies, respectively), as well as for PTSD, with the HTQ used by 13 studies. The HSCL-25 was created with US participants (Parloff et al., 1954) and the HTQ with participants from South East Asia (Mollica et al., 1992). Some studies, such as Gerritsen et al. (2006) and Nakash et al. (2017), have adapted these tools for their asylum populations (Afghans, Iranians and Somalis in the Netherlands, and Eritreans and Sudanese in Israel, respectively) through a multi-step process including translation and back-translation, and the addition of culturally relevant items.
Given the different conceptions of mental health across cultures, studies could also usefully examine mental disorders other than, or in addition to, PTSD, depression and anxiety. PTSD, in particular, has been the subject of cross-cultural criticism. Summerfield (1999), for example argues that the diagnosis pathologises normal social responses to trauma and disconnects ‘[victims] from others in their community and from the wider context of their experiences and the meanings they give to them’ (p. 1456). Miller et al. (2006) provide a possible way forward in their development of the Afghan Symptom Checklist in collaboration with Afghan academics and community members. This scale was partly developed through common elements in community narratives of well-being.
Identifying and making use of evidence from non-Western countries may require Western academics to draw upon a broader range of concepts and terms for mental health, including spiritual health. For example, Baasher (2001), writing from the University of Khartoum, argues that the Quran comments on mental health when giving directives for ‘a firm belief… endurance of hardship and resolution of stress’. Many health and well-being papers from Iran focus on spiritual mental health, using the spiritual well-being scale developed by Paloutzian and Ellison (1982) (e.g. Sharif Nia et al., 2018; Niyazmand et al. 2018; Ziapour et al. 2017). Papers may also focus on culturally specific mental health terms such as Zar, an Iranian condition where a spirit takes control of a person, invading their heads and leading them to harm (Moghaddam, 2012). Analysis of studies included in our review (Jannesari et al., 2020) suggests that research conducted in non-Western settings is currently underutilised. For example, English language studies conducted with Afghan forced migrants in Iran and Pakistan (e.g. Kalafi et al., 2002; Naeem et al., 2005), which host the majority of Afghan refugees (UNHCR, 2019), were rarely cited by the studies eligible for inclusion in our review, including those whose samples comprised Afghans.
The range of risk factors investigated
Our review's (Jannesari et al., 2020) updated figures comprise 29 distinct social environmental factors (i.e. the relationships, culture, government and settings people live in) that were tested for association with mental disorder among people seeking asylum in at least three studies. We grouped these factors into seven thematic categories: healthcare, social networks, community and identity, economic class, working conditions, immigration system, and living conditions (see Fig. 1).
Fig. 1.

Identified factors were unevenly studied with some domains attracting relatively little attention. Compared to most other themes, factors relating to living conditions were seldom examined. Yet, housing is an important indicator of migrant integration, crucial : to a ‘sense of security and stability, opportunities for social connection, and access to healthcare, education and employment’ (Ager and Strang 2004, p. 15) with well-established links to mental health in the broader literature (e.g. Chambers et al., 2018). Bhui et al.'s (2012) study on ‘forced residential mobility’ and psychiatric disorders was a welcome exception, collecting ‘detailed accommodation histories’ of Somali migrants.
Homelessness was rarely assessed by the studies in our review's (Jannesari et al., 2020) updated statistics. Homelessness is a risk for those seeking asylum as Government support may be difficult to access and many might not be eligible to receive it. An Australian charity surveyed 203 asylum seekers (Mitchell and Kirsner, 2004), finding that 95% had no form of income, with 44% in debt. Resultantly, ‘at least 68% were homeless or at risk of being homeless’. In the UK, the application form for asylum seeker support is difficult to complete being 32 pages long, available only in English and accompanied by a 17-page guidance document (Home Office, 2013). There can be delays in a response and some people are left street homeless (UK Parliament, 2007).
There are other factors around housing, mental health and asylum which future work could explore in addition to those shown in Fig. 1. Freedom to enter and leave accommodation may be important. Research has shown that restrictions on movement, such as detention, are a mental health risk for people seeking asylum (see Robjant et al., 2009). Accommodation setting (e.g. urban or rural) could also be investigated. It affects access to diaspora networks, a risk factor associated with mental disorder (e.g. Byrskog et al., 2016). People in isolated areas may be more lonely or bored, commonly assessed risk factors in the literature (Jannesari et al.,2020).
Our review's (Jannesari et al., 2020) updated statistics only identified four types of risk factor relating to working and working conditions. Though unemployment was well-researched (28 studies), crucial factors were omitted. For example, few studies in our review explicitly examined workers' rights: worker exploitation is associated with poor mental health in migrant workers (e.g. Hovey and Seligman, 2006). In the UK, US and German detention centres, asylum seekers may be working for as little as €0.80 per hour (Kasinof, 2017; Bales and Mayblin, 2018). Similarly, limitations on people's ability to move between employers may increase vulnerability to abuse and exploitation (e.g. Khan, 2014; Balasubramanian, 2019).
Future studies could focus on the stability of employment; whether someone works regular hours, or is in a more precarious situation (e.g. on a zero-hour contract). Precarious work can be an issue among the general migrant population (e.g. Burgess et al., 2013; Campbell and Burgess, 2018) and relates to depressive symptoms (Kim and von dem Knesebeck 2016). The areas detailed in the World Health Organisation's (2019) factsheet on mental health in the workplace could be usefully investigated. Risk factors encompassed ‘limited participation in decision-making or low control over one's area of work’. A UK study found that lack of control was a source of mental health distress for people seeking asylum (Jannesari et al., 2019).
Variation in risk factor measures
Our original systematic review identified 21 studies with sufficient data for inclusion (see Table 1, Jannesari et al., 2020). From this wealth of data, we were able to synthesise findings for just two risk factors: discrimination and unemployment. The majority of potential risk factors we identified were measured in only a small number of studies and, often, findings relating to these factors were not disaggregated by mental health status. The Post-Migration Living Difficulties checklist (PMLD) developed by Silove et al. (1997) provides consistency in the field, being used by 17 of 49 studies in our review's updated numbers. However, studies often used different versions of the checklist comprising anything from 13 to 31 total items, making synthesis difficult. Items relating to key domains identified in Fig. 1, such as living conditions, were sometimes omitted. The COMET initiative (Williamson et al., 2017) could provide a way forward. COMET seeks to produce a set of core measures to be assessed across clinical trials in a given area of health research : improving the relevance of outcome measures and the synthesis of evidence, as well as reducing outcome reporting bias.
Our review (Jannesari et al., 2020) also identified a lack of nuance in the measurement of included risk factors. Sometimes, risk factor measures relied on the extent of agreement or disagreement with a single statement. This is, for instance, the case with the PMLD (Silove et al., 1997). It meant that complex items such as discrimination, which one or two studies divided into subcategories (e.g. Laban et al., 2005), was reduced to a simple concept with limited practical value. Similarly, major potential confounders were sometimes overlooked. For instance, most studies asking about employment did not ask whether people were working legally or illegally. We suggest a move away from large single-item lists and towards a core set of indicators measured using scales, and applied consistently throughout studies.
The use of the legal term ‘asylum seeker’
Our review (Jannesari et al., 2020), as well as the appraised reviews (Patel, 2011; Ryan et al., 2009), used the legal definition of asylum seeker to define study population. This reflects standard practice in forced migration literature and the lack of viable alternatives. However, migrants are subjected to a multitude of ‘legal, bureaucratic and social labels’, each with their own associated constraints and opportunities (e.g. Janmyr and Mourad, 2018). Thus, co-nationals sharing the legal category ‘asylum seeker’ might have substantially different experiences, even if they reside in the same host country. Conversely, those in other legal categories may have very similar experiences.
Two ‘asylum seekers’ in the same country can have very different experiences based on their nationality. In 2015, the Dublin agreement, a law enabling deportation to the first EU country entered, was suspended in Germany for Syrians (Dernbach, 2015). The rate of positive first decisions for Syrians in Germany was 98% with 101 415 being granted status (Eurostat, 2020). The government prioritised Syrian cases and decisions took around 3 months (AIDA, 2016). This compared to 17 months for Iranians and 14 for Afghans (Federal Government, 2019). Many Syrians were granted status based on a questionnaire and without any interview (AIDA, 2015), unlike all other nationalities for which an interview was obligatory. Combining Syrians, Iranians and Afghans within a single category of asylum seekers provides limited conceptual value.
Defining study populations using the legal term ‘asylum seeker’ can exclude other migrants who have sought sanctuary and undergone similar processes. Syrians seeking asylum in Germany in 2015, for instance, may have had some similar post-migration experiences to North Korean defectors to South Korea. North Koreans are also all accepted after identity and security checks (ICG, 2011). Defectors are initially housed in reception centres where they are provided integration information. This is comparable to the Syrian asylum experience in Germany where people stay in initial reception centres (AIDA, 2015).
We offer the concept of ‘sanctuary seekers’ – people who have fled their country and are asking another country for safety and residence – as an alternative to the legal category ‘asylum seeker’ in defining study populations. Though it requires empirical testing, we propose grouping sanctuary seekers based on the difficulty of obtaining permanent status and how supportive post-migration conditions are for integration. Decision waiting time, acceptance rates by nationality, interview processes and access to legal aid could assess the difficulty of attaining status. Temporary status rights, suitable accommodation and path to permanent settlement could assess post-migration conditions for integration. Alongside this rich set of indicators, legal category may aid in understanding experience. The term sanctuary seekers helps avoid the fragmentary labels imposed by governments that restrict migrant rights (Zetter, 2007).
Figure 2 illustrates how categorisation based on shared experience could group populations, with the y-axis representing the difficulty in obtaining permanent status and the x-axis supportive conditions for integration. Three groups emerge. Top left are sanctuary seekers enduring relatively high stress, defined as living in poor conditions while having few or no options to resolve their situation. In the middle are those under comparatively medium stress; though there are limited options, a path does exist to a stable life either through employment and integration, or permanent status. Bottom right are people for whom the process of obtaining status is typically an identity and security check; these people will almost certainly receive status and benefit from a range of support. We recognise that no categorisation can capture the full depth of someone's experience; even using our method, many experiences are excluded. In addition, rights and conditions are only considered at a single point in time.

Conclusion
Drawing on our systematic review, we have identified four challenges to the synthesis of evidence and the development of evidence-based responses to the mental health needs of forced migrants: the reliance on Western conceptions of mental health, the under-investigation of potential risk factors, the variability and lack of nuance in risk factor measures, and the use of the legal category ‘asylum seeker’ to define study population. We have suggested that future research draws on a broader conceptualisation of mental health, have called for the development of a core set of outcomes and measures to enhance the consistency of reporting and comparability of findings, and offered the concept of sanctuary seekers as an alternative to the legal category asylum seeker when defining study populations. Ultimately, we call for a more coherent, collaborative and international literature so we can better meet the mental health needs of people forced to flee their homes.
