Abstract
Background:
According to the United Nations Commissioner for Refugees (UNHCR), children and adolescents represent 41% of all forcibly displaced individuals. They have to deal with conflicts, violence, and the many difficulties of flight and resettlement during a critical stage of their emotional, social, cognitive, and physical development. They are more likely to experience mental health problems during migration. Despite the several known risk factors, it is frequently challenging for refugees and asylum seekers to get mental health care. In this paper we review available studies on interventions aimed at promoting mental health and at preventing common mental disorders in immigrant adolescents and children.
Methods:
The relevant PubMed, Scopus, PsychINFO and Web of Science databases were searched for papers published until March 21, 2023, using (“immigrants” OR “migration” OR “asylum seekers” OR “refugees”) AND (“promotion” OR “prevention”) AND (“mental health” OR “mental disorders” OR “psych*”) AND (“children” OR “adolescents” OR “young adults”) as search string. Fourteen articles qualified for the detailed review.
Results and Conclusions:
The majority of available interventions, although highly heterogeneous in format and content, showed significant improvement in several psychopathological dimensions, including trauma-related symptoms, psychological stress, anxiety, depressive and cognitive symptoms. Available studies on interventions for the prevention of mental disorders and the promotion of mental health in refugees and asylum seekers children and adolescents indicate that provided interventions were associated with a global improvement for participants. Implementation strategies to improve their scalability are highly needed.
Introduction
According to the United Nations, at the end of 2021, 89.3 million individuals worldwide were forcibly displaced as a result of persecution, conflict, violence, violation of human rights or events seriously disturbing public order. Among these, 53.2 million were internally displaced, 27.1 were refugees and over 4.6 million were awaiting a decision on their asylum application (Lasrado et al., 2021; Silove, 2021). These numbers are expected to rise due to the ongoing conflicts and to the impact of climate change leading to more frequent natural disasters (Beine & Jeusette, 2021; Braithwaite et al., 2019; Cattaneo et al., 2019; M. Chen & Caldeira, 2020; L. Perch-Nielsen et al., 2008; Mazhin et al., 2020).
According to the United Nations High Commissioner of Refugees (UNHCR), children and adolescents represent 41% of all forcibly displaced individuals. They have to deal with conflicts, violence, and the many difficulties of flight and resettlement during a critical stage of their emotional, social, cognitive, and physical development; as a result, they are more likely to experience mental health problems during migration (Bloomfield et al., 2021; M. D. Fazel et al., 2012; Griswold et al., 2021; Pezzella & Giordano, 2022; Williams & Etkins, 2021). Young refugees who were resettled in European Countries have prevalence rates of 53% for posttraumatic stress disorder (PTSD), 33% for depression, and up to 32% for anxiety disorders (Kien et al., 2019; Nickerson et al., 2011). However, there is a significant heterogeneity in the prevalence rates of mental health problems among studies, considering that some studies have found PTSD rates up to 87% in refugees (Blackmore et al., 2020; Vossoughi et al., 2018).
The risk factors for the onset of mental disorders in young refugees can be grouped in three categories, according to the chronological occurrence during the migratory experience (i.e. during pre-, peri, and post-migratory histories) (Hollis, 2022; Kieling et al., 2022; Lustig et al., 2004; Silove & Ventevogel, 2022). In addition to detention, food deprivation, and separation from their parents or guardians during the migration process, children and adolescents frequently endure interpersonal violence, poverty and living in needful conditions in their native countries (Cannon et al., 2022; E. Y. H. Chen & Wong, 2022; Fuentes & Vannelli, 2019). They continue to face difficulties once they get to the new country, some of which depend on the nature of the resettlement regions (Gleeson et al., 2020; Jannesari et al., 2020). High income countries (HIC) may guarantee safer conditions and basic necessities, but children and adolescents who are part of the population of refugees and asylum seekers (RAS) are frequently exposed to transcultural stressors (e.g. discrimination, difficulties learning a new language, dealing with bureaucratic challenges related to their asylum application or their school) (Almohamed & Vyas, 2016; Frounfelker et al., 2020; Kiselev et al., 2020; Tarsitani et al., 2020). Children and teenagers frequently reside in sizable, congested refugee camps in low- or middle-income countries (LMIC), under poor hygienic conditions, shortage of food, and high levels of violence (Arango et al., 2021; Beza et al., 2022; Leiler et al., 2019; Scharpf et al., 2021; Walther et al., 2020). Moreover, in addition to the traumatic events that occurred prior to migration, post-migratory stressors may pose a serious threat to the mental health and welfare of refugees (Bryant, 2022; Greenberg & Rafferty, 2021; Li et al., 2016; Miller & Rasmussen, 2010). Among the pre-migration risk factors, having pre-existing mental health problems can be considered one of the most significant factors contributing to increase vulnerability in child and adolescent refugees and asylum seekers. In particular, neurodevelopmental disorders, such as autism spectrum disorders (ASD), attention-deficit/hyperactivity disorder (ADHD) and learning disability (LDs), are the most frequently reported, with prevalence rates of 1.85% for ASD, 5.29% for ADHD and 16.65% for LDs. Migration is considered to be a risk factor for such diseases, making RAS children and adolescents at increased risk (Gao et al., 2022).
Despite the several known risk factors, it is frequently challenging for refugees and asylum seekers to get mental health care, largely due to constrained mental health care services (Asgary & Segar, 2011; Fusar-Poli et al., 2021; Nordentoft et al., 2021; Satinsky et al., 2019). Furthermore, access to psychiatric care is frequently hampered by logistical, organizational, as well as linguistic and cultural barriers (Ohtani et al., 2015; Rosen & Salvador-Carulla, 2022; Tarsitani et al., 2022).
The provision of services to address the psychological conditions in RAS people is often offered by non-government organizations (NGOs) and coordinated by international organizations, including the World Health Organisation (WHO), the UNHCR, and the International Federation of Red Cross and Red Crescent Societies. An evidence-based response from health systems is either lacking or incomplete (Acarturk et al., 2022).
The mental health of RAS people has become a focus of attention from the scientific community only recently. Although several reviews on the effectiveness of mental health promotion, and on prevention and treatment of common mental disorders for refugees, asylum seekers, and internally displaced persons are already available (Cuijpers et al., 2021; Morina et al., 2018; Murray & Cannon, 2021; Uphoff et al., 2020), there is a lack of evidence on interventions for the promoting of mental health in child and adolescent refugees and migrants (Uphoff et al., 2020).
In this paper we review available studies on interventions aimed at promoting mental health and at preventing common mental disorders in immigrant adolescents and children. For the purpose of the present study, a psychosocial intervention is defined as “any action intended to interfere with and stop or modify a process, as in treatment undertaken to halt, manage, or alter the course of the pathological process of a disease or disorder,” according with the Dictionary of Psychology of the American Psychological Association (APA) (APA, 2023). According to the WHO, promotion and prevention interventions are effective if the social, individual, and structural determinants of mental health are identified in order to reduce risk factors, build resilience and establish supportive environments for mental health (WHO, 2022). Mental health promotion interventions include those promoting global functioning and well-being rather than addressing a specific mental illness, and they might be targeted to the entire population or to high-risk populations, such as the RAS group. Interventions for the prevention of common mental disorders are usually focused on general mental health or on specific common mental disorders. Preventive interventions can be universal, selective (focused on at risk individuals or groups) or indicated (for individuals that show symptoms of mental health problems but have no diagnosis). Prevention focuses on avoiding disease and associated risk factors, while promotion aims at improving mental health (Singh et al., 2022).
Methods
The relevant PubMed, Scopus, PsychINFO and Web of Science databases were searched for papers published until March 21, 2023, using (“immigrants” OR “migration” OR “asylum seekers” OR “refugees”) AND (“promotion” OR “prevention”) AND (“mental health” OR “mental disorders” OR “psych*”) AND (“children” OR “adolescents” OR “young adults”) as search string. Studies were included in the review if they: (1) involved subjects aged 0–18 years and with a history of migration; (2) included the administration of an intervention for the promotion of mental health or the prevention of mental disorders in RAS children and adolescents; (3) were written in English.
Studies including parents or families of RAS children and adolescents were included in the review only if it was possible to extrapolate the effect of the interventions on the child/adolescent. Feasibility studies and qualitative studies were excluded. Pilot studies were included only if they could bare data on the study effectiveness other than its feasibility.
In addition, the reference lists of all included studies and of relevant existing systematic reviews were checked for possible studies. After removing duplicates, full reports of potentially relevant studies were obtained, and three authors (BDR, RB, CT) independently extracted content by the papers.
Data on study design, sample characteristics, age range of recruited subjects, type of intervention, presence of a control group, and main outcomes were extracted independently by three authors (RB, CT, BDR); discrepancies were resolved by discussion with a senior expert (ML).
A narrative synthesis was then undertaken. All studies included in the review were analyzed in order to group them in categories, and main results were summarized.
Results
Entering the key words in the relevant databases, 3,935 papers were identified; 1942 were excluded as duplicates. After reading the abstracts, 1979 additional papers were eliminated because they did not meet the inclusion criteria, leaving out 14 papers to be included in our review (Figure 1).

PRISMA flow-chart.
Most of the interventions (10 out of 14) were carried out in high income countries. Five out of 14 were directed at children (0–12 years of age), four at adolescents (13–18 years of age) and five at both age ranges. A brief description of every intervention is provided in Table 1.
Description of interventions included in the review.
Most studies (10 out of 14) were randomized controlled trials, with one of them comparing three different arms. Half of the interventions were targeting children or adolescents directly, while the other half were involving families or mother-child dyads. The number of participants in each study ranged from 30 participants to broader trials with samples of 479 families. A brief description of the mentioned interventions and detailed results can be found in Table 2.
Overview of studies included in the review.
Family-oriented interventions
Betancourt et al. (2020) investigated the effectiveness of the Family Strengthening Intervention (FSI-R), consisting of approximately ten 90-min weekly home-visit sessions by well-trained professionals from the refugee community, who were weekly supervised by licensed clinical social workers and every 2 months by a larger team including clinical supervisors and research staff (Betancourt et al., 2020). This RCT shows that children whose families received the intervention reported significant gains in mental health, as shown by a reduction in levels of traumatic stress reactions compared to children in the group receiving Treatment as Usual (TAU). Moreover, a reduced levels of depressive symptoms in the experimental treatment was also reported.
Promising results were also found with the Teaching Recovery Techniques (TRT) intervention, an evidence-based manualized intervention aiming at mitigating the psychological consequences of war and violence on mental health (El-Khani et al., 2021; Sarkadi et al., 2018). Both studies reported a positive effect of TRT in reducing both PTSD and depressive symptoms in adolescents (Sarkadi et al., 2018) and an improvement in behavioral and emotional difficulties in children (El-Khani et al., 2021). Moreover, a significant reduction in depressive, anxiety, and stress symptoms in caregivers were reported when TRT is associated to parenting skills training.
Lebiger-Vogel et al. (2022) assessed the impact of FIRST STEPS intervention, a psychoanalytically-oriented prevention program for immigrant families, aiming at improving child development and parenting skills in migrants. Despite not addressing directly children with mental health problems, the study of Lebiger-Vogel was retained in this review since it found that children with developmental delays are more likely to experience clinically significant behavioral and emotional problems compared to children with regular development (Caplan et al., 2015). Authors reported that the intervention was effective in preventing early developmental delays in immigrant children and improving school performance of participants (Lebiger-Vogel et al., 2020).
Bacallao and Smokowski (2009) assessed the efficacy of “Entre Dos Mundos (EDM)” intervention, an 8-week prevention program adopting a multifamily group format to discuss acculturation stressors and challenges (Bacallao & Smokowski, 2009). The provision of EDM was associated to lower rates of oppositional defiant behavior, anxious and depressive symptoms, and reduced parent-adolescent conflicts.
Annan et al. (2016) tested the efficacy of the “Happy Families Program” (HFP), a family skills training program originally developed in the USA for substance abusing parents and their children. Effectiveness was measured in terms of children’s behavioral and emotional problems and psychosocial protective factors. Treated children showed a significant reduction in externalizing problems and attention problems compared with controls. Moreover, a significant increase in psychosocial protective factors, such as sources of support, positive social skills, positive emotional outlook and self-esteem, was also found in treated children compared with controls (Annan et al., 2016). These findings show that an evidence-based parenting skills’ intervention adapted for displaced and migrant people facing high levels of adversities can have positive effects on children’s externalizing symptoms and protective psychosocial factor.
Child and/or adolescent-oriented interventions
Barrett et al. (2003) investigated the effects of the FRIENDS intervention, an internationally recognized early intervention program for children and adolescents delivered by trained bilingual mental health professionals to small groups (Barrett et al., 2003). Elementary school children who completed the intervention reported significant improvements in self-esteem, expectations for the future and a significant decrease in anxiety symptoms. High school students who participated in the program reported significantly reduced levels of anger, anxiety, depression, post-traumatic stress, and dissociative symptoms. Adolescents in the waiting list group reported an increase in anxiety symptoms from pre- to post assessment. Moreover, improvements in resilience were sustained in the long term. Thus, the FRIENDS program is effective in reducing anxiety and stress that accompany cross-cultural migration, promoting long-term self-esteem and a less pessimistic view of the future.
Ellis et al. (2013) tested the efficacy of the SHIFA (Supporting the Health of Immigrant Families and Adolescents) program on the reduction of trauma-related and depressive symptoms (Ellis et al., 2013). The program is divided into four different tiers; the first is the broadest level of service, which includes community engagement and parent outreach. Tier 2 consists of school-based groups open to all English language learner students in the participating school. Tiers 3 and 4 include direct mental health intervention for students with significant mental health needs. Results showed that students across all tiers of the program demonstrated improvements in both mental health and resources. Contrary to the authors’ expectations, improvements in mental health and resources were not different between those receiving the lower intensity Tier 2 level of services and those receiving Tiers 3 and 4.
Clauss et al. (2023) evaluated the effects of a resilience-focused group program. This intervention was piloted in three cohorts of adolescents (n = 11, 10, and 7, respectively) with subclinical psychiatric symptoms (i.e. emotional problems, conduct problems, hyperactivity, peer problems, and social behaviors) living in low-income, Latin immigrant communities. Results showed that the intervention is associated with reductions of transdiagnostic psychiatric symptoms (i.e. depressive and anxiety symptoms) and promoted social participation and emotional recognition (Clauss et al., 2023).
Art and expressive workshops taking place in school settings were proposed as preventive interventions in different studies (Rousseau et al., 2005, 2007, 2009). In the 2005 study, the authors assessed the efficacy of expressive workshops in terms of reduction of (internalizing and externalizing) symptoms and of popularity and integration. Children from the experimental group reported a significantly lower level of mental health symptoms than those in the control group, and higher levels of feelings of popularity and satisfaction (Rousseau et al., 2005). The results of this study show that a simple, school-based, low-cost intervention is effective in promoting mental health in young refugees. The second workshop (2007) was part of the regular school day. Although authors did not report improvement in self-esteem or emotional and behavioral symptoms, adolescents in the experimental group showed an increase in performance in mathematics and lower levels of impairment by symptoms than those in the control group (Rousseau et al., 2007). The third workshop, which was designed for preschoolers (2009), consisted of creative expressive workshops using sandplay. Children in the experimental group benefited moderately from the program, with a reduction of emotional symptoms. The intervention was also useful to prevent the increase in emotional and behavioral symptoms (Rousseau et al., 2009).
Thabet et al. (2005) tested the efficacy of a group-crisis intervention in a sample of children and adolescents with mild to severe symptoms of PTSD, living in the Gaza Strip. Authors did not report a significant impact of the intervention on children’s posttraumatic and depressive symptoms. These findings might be due to the continuing exposure to trauma and the non-active nature of the intervention (Thabet et al., 2005).
Child- and youth-friendly spaces are an important feature of emergency humanitarian provision. To provide educational services in Ethiopia’s Buramino camp, World Vision Ethiopia opened its first child and youth learning center (CYLC) in January 2012. This offered a location in which a range of activities were available for children aged from 6 to 17 years. The effects of these camps in terms of educational and psychosocial outcomes were investigated by Metzler et al. (2021). No structured intervention was available; the centers were considered to be short-term interventions while the camp was set up, in advance of the provision of formal education. Results from this study showed a general improvement in prosocial behavior and emotional and social adjustment, as well as in internal and external coping resources available in both camp-attending and non-attending children (Metzler et al., 2021). This was explained as a general adaptation to the harsh camp conditions. However, a particular reduction in psychosocial difficulties was found in children attending the CYLC.
Discussion
Interventions aiming to prevent and promote the mental health in high-risk populations, such as RAS children and adolescents, is crucial for reducing the risk of developing common mental disorders, promoting social inclusion and improving mental health and well-being (M. Fazel & Betancourt, 2018; Onoja et al., 2020; Pejušković & Vukčević-Marković, 2020; Peterson et al., 2020; Turrini et al., 2019). The majority of the interventions provided, although highly heterogeneous in format and content, have shown significant improvement in various psychopathological dimensions (trauma-related symptoms, psychological stress, anxiety, depression, cognitive symptoms and PTSD), also in the long term. However, several important outcomes, to which this population is considered to be at risk for, were not taken into account by any of the included studies (Hickie, 2022; Malla et al., 2022). In fact, none of the studies investigated if the interventions decreased the risk of developing antisocial behaviors, psychotic symptoms, or a full-blown psychiatric disorder in the long-term. One possible reason is that long-term follow-ups are often difficult in RAS people due to their frequent resettlements and displacements. Such outcomes should be the subject for future research (Patel et al., 2021; Robertshaw et al., 2017).
Furthermore, many interventions were directed not only to the child and or adolescent but involved relatives and caregivers too. Most interventions were also effective in improving parenting skills and promoting a healthy family environment, which are important protective factors for young and adult displaced people (Danese, 2022; Lång et al., 2022; McGorry et al., 2022; Stein et al., 2021).
Improvement of mental health is more effectively evaluated in studies with longer follow-ups, thus requiring longer periods for assessing the efficacy of mental health-oriented interventions. One additional limit might be due to the complex identification of RAS groups which aren’t experiencing severe stress or symptoms, making promotion strategies hard to implement (Mitschke et al., 2017; Priebe et al., 2016; Robertshaw et al., 2017; Sharan, 2022; Thompson et al., 2018).
The promotion of mental health in socially, economically, and culturally disadvantaged groups is one of the many challenges in the field of social psychiatry (Blackmore et al., 2020; Gnanapragasam et al., 2022), despite they represent the optimal target for such strategies, due to the numerous risk factors they are exposed to (Scharpf et al., 2021; Wilson et al., 2021). A full understanding of the importance of such interventions, together with increased appeal and availability are crucial to foster interest and participation from mental health professionals working with migrants and from RAS population. Besides, one consideration to be made when taking the RAS population into account relies on the transcultural nature of refugees and asylum seekers. Interventions need to be readapted not only from a linguistic viewpoint, but also from a cultural one for each specific RAS population, and then be administered to culturally homogeneous groups. As a matter of fact, many of the evaluated interventions were cultural readaptations of already existing evidence-based interventions.
Another relevant finding was that, despite the great feasibility of evidence-based, manualized and low-cost interventions, they are underutilized and poorly investigated, as reflected in the very small sample sizes of studies included in this systematic review. One possible explanation of this phenomenon might be due to the low availability of training and support for mental health professionals (Peñuela-O’Brien et al., 2023). In fact, several authors reported that lack of training greatly affects quality of health care provided to RAS population, which is often provided in settings different from generalistic mental health care settings (Peñuela-O’Brien et al., 2023). There is now enough evidence that psychological interventions for migrants can be adequately provided by trained and supervised persons who are not specialists in mental health (Kohrt et al., 2020; Nosè et al., 2017; Slobodin & de Jong, 2015; Turrini et al., 2021). Establishing competency-based training methodologies and competency assessment standards is one strategy to overcome this problem. With this purpose, the WHO has recently developed the Ensuring Quality in psychiatric Support (EQUIP) platform, to promote competency-based training in psychosocial support, psychiatric treatments, and basic helping skills (Watts et al., 2021). EQUIP is an online resource to evaluate training and to support trainees’ development which contains instructions on how to offer competency-based training programs as well as on how to use and modify psychological therapies. Common components of psychological care and general psychosocial support, such as communication skills, empathy, teamwork, and a helper-client link, are necessary for any intervention to be successful (Hettich et al., 2020). Training and support of non-specialized mental health care providers in the RAS population might be the topic of further investigation.
This review has several limitations. The decision to only include high-quality studies (randomized controlled trials and clinical trials) gave us the possibility to provide an overview on the efficacy of the different interventions, but it considerably reduced the sample of studies to be included. Moreover, the comparison of the different interventions was made more complicated due to the great heterogeneity of considered outcomes in the studies. Also, cultural background might influence how different populations react to different interventions, contributing to the difficulties in the comparison among the different studies (Bryant et al., 2021; Patton et al., 2021; Verkuyten, 2021) . The choice to extend the field of research to interventions that were conducted both in HIC and in LMIC gave a more global perspective, but it represented also a confounding factor when considering the different levels of available resources.
In conclusion, available studies on interventions for the prevention of mental disorders and the promotion of mental health in RAS children and adolescents indicate that, despite their heterogeneity, available interventions yield a global improvement for participants. These results are of particular relevance since child and adolescent refugees and asylum seekers face limited or no access to healthcare services, are frequently marginalized in epidemiological investigations, and are frequently subjected to forced migrations (Carrasco-Sanz et al., 2018; ISSOP Migration Working Group (2018)).
However, these interventions remain underutilized, and a strategy for the implementation and promotion of psychological intervention in this at-risk population is needed. This will not only greatly improve mental and global health in the RAS population, decreasing the incidence of
