Abstract
Today, various questionnaires are available to assess Adverse Childhood Experiences (ACEs) in children; however, it is uncertain if these questionnaires comprehensively address the adversities of vulnerable subgroups, specifically refugee children. This review's objectives are to (1) identify current ACE questionnaires and determine if they are suitable for assessing refugee children’s adversities, and (2) identify those previously used within a refugee population. A systematic literature search was conducted across five databases for articles published since 2010, including studies using an ACE questionnaire that recognized multiple adversities in healthy children and were published in English. A total of 103 ACE questionnaires were identified in 506 studies. Only 14 of the 103 questionnaires addressed a refugee-specific adversity. Their ability to capture refugee children’s experiences was limited: available questionnaires used a maximum of three items to assess refugee-specific adversities, covering only a fraction of forms of adversities relevant to refugee children. Psychometric characteristics were rarely reported. In addition, only two ACE questionnaires were used within a refugee population. With the tools currently available, it is not possible to comprehensively assess the exposure to and severity of the adversities faced by refugee children. The perpetuation of ongoing crises necessitates assessing refugee children's adversities to understand how their well-being is affected and to identify children at risk.

Introduction

Adverse Childhood Experiences (ACEs) are highly stressful, and potentially traumatic, events or situations that occur during childhood and/or adolescence [1]. The Centers for Disease Control and Prevention (CDC) and the Kaiser Permanente popularised this term in their pioneering study exploring the effects of adversity on people's health and behaviour [2]. Their research revealed that children who experience an increasing number of adverse events are more likely to face serious life-long consequences in adulthood such as alcohol abuse and have increased odds for non-communicable diseases such as diabetes or chronic obstructive pulmonary disease [2]. The last two decades of research revealed that ACEs are common and rarely occur individually, thus they have become of global importance [3].
Given global estimates that over half of all children between ages 2 and 17 (i.e., over 1 billion children) experienced some form of adverse event [4], a variety of tools for screening and assessing ACEs in children and adolescents have been developed. These tools aim to identify children most at risk, encourage prevention of further exposure to ACEs, help determine an appropriate treatment for children who had been exposed as well as drive policy and action to better tailor health care measures based on an understanding of how many children might suffer [5].
Some questionnaires primarily focused on a specific type of event (e.g., child sexual abuse), others examined several ACEs yet are limited to the perpetrator (e.g., family member or caregiver) or location (e.g., within the home or at school) [6]. The conventional ACEs (originating from the CDC-Kaiser Permanente study) concentrated on adversities within the home: physical, emotional, and sexual abuse, physical and emotional neglect, and household dysfunction [7,8]. However, given that a child’s wellbeing can be affected by the community and society in which they live, it is also important to acknowledge experiences in these settings that contribute to a child’s quality of life [9]. More recent work, therefore, includes experiences referred to as expanded ACEs that assess exposures such as crime, discrimination, poverty, parents’ unemployment, food insecurity and bullying [10,11]. Despite the expansion of types of adversities, it is unclear whether existing questionnaires are extensive enough to encompass ACEs that may occur in subgroups of vulnerable children.
Refugee children represent one such subgroup given their frequent exposure to adverse experiences [12], including escaping from war zones, violence, conflict or persecution to find safety in another country – often without warning [13]. The estimated number of forcibly displaced children in 2021 was 36.5 million [14] with more than four million children resettling abroad or being internally displaced in 2022 as a result of the war in Ukraine [15]. As nearly 600 million young people live in conflict-prone regions, it is likely these numbers will be sustained or even increase in the future [16].
The adverse events encountered during flight appear to have profound effects, especially in children. Developmental and epidemiological studies suggest, for example that displacement, detention, separation from family, and resettlement [17], may have long-lasting physical and psychological consequences [18], including a higher prevalence of post-traumatic stress disorder (PTSD), anxiety, depression and conduct disorders [19].
The utility of available instruments in assessing these refugee-specific ACEs is currently unclear. The purpose of this review is to identify available questionnaires that assess ACEs in children, and (1) to examine whether and to what extent these questionnaires may be useful in assessing the diverse and often unique adverse experiences encountered by refugee children and (2) to examine which ACE questionnaires have already been used within a refugee population. Identifying gaps in current ACE questionnaires may help guide the development of tools for children subjected to the refugee experience.

Methods

Search strategy

A search of articles published since January 2010 was conducted in four databases: PubMed, Web of Science Core Collection, PsychINFO, and Academic Search Complete. The systematic literature search was initially conducted on October 9, 2018, with updates on February 14, 2020, and on March 1, 2022. The latter two updates were made to identify publications capturing more recent refugee events. Search terms included abuse, sexual abuse, neglect, maltreatment, trauma, violence, stress, household dysfunction, adverse child experience, adverse childhood event, child, infant, adolescent, teenager, youth, questionnaire and survey. The full search strategy for all databases can be found in Appendix 1. In order to avoid limiting the search, the term "refugee" was not included as items might be applicable to refugee children even though they were not intended for application in refugee populations. The study protocol was registered on the international database of prospectively registered systematic reviews PROSPERO (ID: CRD42019121587).
This review aims at identifying questionnaires that recognise multiple adversities in healthy children, as previous literature has identified that many children experience multiple co-occurring ACEs that might impact their wellbeing [20,21]. Thus, included articles used questionnaires that measured more than one ACE, in children under the age of 18 (as per the United Nations definition of a child), and were written in English [22,23]. As interest was only in questionnaires, studies were excluded if adversities were assessed using interviews in the form of a structured conversation. Articles that evaluated children who had a mental disorder prior to measuring ACEs were also excluded due to the focus on examining healthy children, and due to differences in how mental disorders are measured and defined. Additionally, owing to inherent differences between adults and children such as limited vocabulary, cognition, experiences and understanding [24], studies that used the same questionnaire to measure ACE exposure in both adults and children were also excluded, as the questionnaire was not designed specifically for children.

Screening

Two reviewers independently screened all identified articles at the title, abstract, and full-text level using Rayyan (a free web application developed by Qatar Computing Research Institute) to facilitate the screening process. Figure 1 displays the process of selecting articles included in this study. Disputes over the eligibility of studies were resolved through discussion until consensus was achieved.

Data extraction and item assessment

A standardised data extraction form, developed by the first author, was used when reviewing information found in a study reporting use of a questionnaire. Extracted data included the country where each study took place, study population characteristics, mode of data collection, name of the questionnaire, questionnaire items and psychometric properties.
Questionnaire items were retrieved either from the published article, survey websites or from personal communication with the original study authors. In this review, ACEs were categorised into 11 categories defined by the research team. The first six categories as displayed in Table 1 were referred to as the conventional ACEs originating from the CDC-Kaiser Permanente study [7,8]. The following four categories were considered expanded ACEs including adversities identified in recent literature such as community violence [25,26,27,28,29]. ACEs were classified as refugee-specific based on the definition of a refugee and also guided by our recent qualitative findings [30]. A refugee is someone who has been forced to flee his or her country because of persecution, war or violence [13], accordingly refugee-specific ACEs include, but are not limited to, exposure to war/conflict, shootings, bombs and riots, displacement and family separation. Different forms of adversities for each category are listed in Table 1 (expanded on findings by Laurin et al., 2018 [31]).
Psychometric properties help assess the degree to which a questionnaire measures the desired content and whether the data it yields are reproducible [32]. Therefore, as a quality assessment, we identified whether retest reliability, internal consistency, inter-observer reliability, content validity, criterion validity, construct validity including cross-cultural validity (if applicable) had been reported as outlined in previous work by de Souza et. al, 2017 [32] .
A second research team member independently crosschecked all the extracted data of 100 randomly selected articles with the original articles. Minor differences, such as labelling of demographic information were discussed until agreement was achieved. Since there were no major differences, duplicate checking of all reports was deemed unnecessary.

Analytic Strategy

The unit of analysis in this study is the questionnaire itself. To determine whether ACE questionnaires are useful in evaluating adversities that refugee children may encounter, a descriptive record of characteristics (i.e., the adversity categories and forms measured and psychometric properties reported) was made. With attention on those questionnaires that measured refugee-specific ACEs, the analytic strategy involved two focuses: (1) to assess ACEs of each category by recording which questionnaires measured which form of adversity. (2) To examine the extent to which each adversity category had been measured by recording the number of questions addressing each category; the use of multiple rather than single questions indicated a higher extent.
To recognise the quality of the questionnaires, information regarding three aspects of reliability and four aspects of validity was extracted from all the studies identified in this review that reported this information. For the questionnaires that addressed a refugee-specific ACE, the number of studies that reported on the individual psychometric aspects were assessed. These topics are discussed further in the following sections.

Results

A total of 506 full-text articles fulfilled the inclusion criteria, in which use of 103 unique questionnaires was reported. Questionnaires were administered mostly via self-report (n= 286 studies), and data collection usually was by means of a household survey (n= 237 studies). The number of participants varied from 29,696,808 to 14, as some of the questionnaires were used as part of national surveys. Most of the studies were conducted in the United States of America (USA) (n= 274 studies), and most of the questionnaires were in English (n= 315 studies).

Adversities measured

The identified questionnaires measured different adversity categories that could be relevant to refugee children, yet only 14 included one or more questions addressing a refugee-specific adversity. Exposure to war/conflict and family separation were the forms of refugee-specific ACEs being addressed most frequently with 10 questionnaires addressing war/conflict and seven addressing family separation. Being beaten up by soldiers, police, militia or gangs was addressed by only one questionnaire, displacement by two and exposure to shootings/bombs/riots by three questionnaires. An overview of which form of adversity is assessed by which of these 14 questionnaires can be found in Figures 2a-2c.

Within the identified 14 questionnaires, one to three questions addressed refugee-specific adversities, whereas other categories were addressed by up to 21 questions such as community violence in the National Surveys of Children’s Exposure to Violence (NatSCEV) [33]. In the NatSCEV, questions about community violence included "Has your child ever lived in a neighborhood where there were gangs?" as well as " At any time in your child’s life, has your child ever seen the police raid or enter a house in (his/her) neighborhood looking for a criminal or block off a place in (his/her) neighborhood because a crime happened there?" Table 2 shows the number of questions addressing each adversity category in each questionnaire.

Psychometrics and questionnaire quality

Very few articles reported any information related to the psychometric properties of the questionnaire used. From the 14 questionnaires that included a refugee-specific adversity, three questionnaires (JVQ, ICAST-C and ACEQ-R) had reported psychometric properties. In this review, these three questionnaires were used in more than one study; however, their psychometric properties were not always reported. For instance, as displayed in Table 3, the JVQ was used in 76 different studies, of which only 15 had reported internal consistency (cronbach’s alpha or Kruder and Richardson Formula 20), 8 reported inter-observer reliability (kappa adjunction) and only one reported content validity (reported via qualitative approach). The JVQ was originally developed in the USA and was used in nine countries beyond the USA within 39 studies identified in this review; yet only four identified studies reported the translation process. None of the studies reported retest reliability (interclass correlation coefficient value), criterion validity (correlation coefficient) or construct validity (convergent validity, discriminant validity or confirmatory factor analysis).

Questionnaires used within a refugee population

In this review, two questionnaires were used to measure ACEs in refugee children, the first questionnaire was the ISPCAN Child Abuse Screening Tool-Child (ICAST-C), used as a self-report measure in one study with children in refugee camps in Rwanda and Uganda [46]. The other questionnaire was the ISPCAN Child Abuse Screening Tool-Parent (ICAST-P), applied in a study asking mothers about the adversities of their Palestinian children, some of whom were displaced refugees in the West Bank [47]. While the ICAST-C addresses refugee-specific ACEs, this is not the case with the ICAST-P.

Discussion

The purpose of this review was to determine if any of the existing questionnaires assessing ACEs also capture the diverse and unique adversities faced by refugee children and if so, to what extent. Further, we analysed which of the available ACE questionnaires had been applied in a refugee setting. This study identified 103 questionnaires that measure various adversity categories yet the core content included within the questionnaires differed, as did the questionnaire quality. Due to the high number of questionnaires identified, it has become apparent that ACEs are perceived globally as a problem. However, it seems that some vulnerable populations, such as refugee children, currently might go unrecognised.

Adversities measured

The range of adversities covered in questionnaires available today has expanded immensely since the conventional ACEs were first revealed in 1998 [2]. Not only do current adversities vary in source (the child’s family or environment) but also in severity and exposure (either witnessed or experienced). However, only 14 of the 103 identified questionnaires included a refugee-specific ACE. Examples of refugee-specific ACEs in the identified questionnaires included experiencing war, bombings, destruction, displacement, and separation from family due to immigration. However, it is important to consider that refugee children may also face adversities similar to the general public that are relevant to their circumstances, such as economic hardship, kidnapping, bereavement and discrimination [48,49].
Table 4 depicts an overview of potential ACEs that might be relevant to the refugee population based on previous research [50,51,52,53,54,55,56,57,58,59], including several adversity forms applicable to both the refugee and general population. For a better overview the figure below also shows which adversity forms have been covered by the 14 identified questionnaires that included at least one refugee-specific item. It becomes apparent that none of the identified questionnaires addressed all forms of adversities – furthermore, several forms of adversity relevant to refugee populations (such as military groups, immigration detention, immigration stress, and acculturation stress) were not addressed within any of the questionnaires identified in this study.
One questionnaire covered all the ACE categories employed in this review: the BARC Pediatric Adversity and Trauma Questionnaire [60] (see Table 2). However, when looking at the breakdown of adversities as depicted in Table 4 it is noticeable that certain issues are missing: kidnapping (a form of community violence), a reality many refugee children might face [49], is not addressed in the BARC questionnaire. Neither is financial difficulties [61], displacement [51], or immigration process [57], all common refugee adversities acknowledged in earlier research.
Furthermore, taking a closer look at the extent to which refugee-specific ACEs are measured in the 14 identified questionnaires, it is noticeable that their measure is limited with a maximum of three refugee-specific questions. For example, the NatSCEV, only addressed refugee-specific ACEs with three questions (war/conflict, shootings/bombs/riots and family separation) while community violence and family disfunction were addressed with 21 and 18 questions respectively, as shown in Table 2. Six of the 14 questionnaires used two questions to ask about refugee-specific ACEs [62], another six tools used only one question [63]. Additionally, the majority of questionnaires addressed refugee-specific ACEs by asking about exposure to war/conflict and/or separation from family. Despite the damaging influence of such exposures, they are not the sole sources of adversity among refugee children. It is therefore unjust to simplify refugee specific adversities into three questions or less. Simply addressing only a few forms of adversities understates the gravity of the refugee experiences, as well as their mental and physical consequences.
It was also noticeable that the questionnaires addressing refugee-specific adversities focused on pre-flight and flight stressors. The tragedies refugee children experience are not only occurring in their home countries, but also on the dangerous route to safety, and in their host countries [64]. In some circumstances, the adversities faced post-flight have caused more of a negative impact on refugee’s wellbeing than that of war and conflict [65,66].
In addition, it is important to acknowledge that factors on multiple levels could be a source of adversity. These factors could arise from the individuals themselves, their families, community or society, such as psychological vulnerabilities, impaired parenting, community tensions or national policies that adversely affect refugee children. However, looking at potential factors arising from all sources with one questionnaire appears to be uncommon in ACE research.
This demonstrates that even in the 14 identified questionnaires, the refugee-specific ACEs are not capturing the full range of adversities these children may encounter. However, it has to be acknowledged that the identified questionnaires were not developed for refugee children and their importance should not be diminished in any way. It becomes apparent, nevertheless, that a gap exists concerning measuring refugee children’s adversities.

Questionnaire Quality

Most articles in this review provided little information about the psychometric properties of questionnaires used. Taking a deeper look at studies identified in this review that used a questionnaire evaluating refugee-specific ACEs, only three out of 14 questionnaires had psychometric properties reported, with several psychometric aspects lacking [67]. In some cases articles stated that the psychometric properties were reliable due to the extensive use of the questionnaire in previous studies [68]. In other cases, vague statements such as the questionnaire has shown “acceptable psychometric properties” [69], were not sufficient to estimate the quality of the tool. The articles that did provide some details about psychometric properties mainly reported on internal consistency, as shown in Table 3. This assesses whether the items of a questionnaire measure the same characteristic, usually by providing a Cronbach’s alpha value. However a Cronbach’s alpha value is greatly affected by the number of items in the questionnaire, by simply increasing the number of items the alpha values are also increased, this alone is not enough to assess the questionnaire quality [32].
Additionally, there was an underreporting of cross-cultural validity of the questionnaires. In those few studies reporting on cross-cultural validity, only the translation method, e.g. forward translation [70] or back translation [71], was described, yet the tool’s adaptability in a new cultural setting was described in none of the identified studies that used the questionnaires in a setting different from its original intent. To minimise bias when the questionnaire is administered in a different language and context, cross-cultural adaptation is essential, and this entails both linguistic and cultural considerations [72].
While psychometric properties for the respective questionnaires might be published elsewhere not included in this review, the missing report of properties within the studies identified in this review still is problematic because reliability and validity are subject to change according to the context, study type, population and purpose of the study [32].
Generally, questionnaires should meet valid and reliable criteria by measuring its psychometric properties to ensure that the questionnaire measures what it proposes and reproduces the same results over time [32]. Research has also indicated that the evidence regarding psychometric properties of adversity questionnaires is limited and usually of lower quality [73,74]. To collect accurate data, researchers should also take into account factors that influence the quality of information such as the respondent characteristics, for instance age or cultural appropriateness [24]. Consequences of ACEs might be obscured due to the variable validity and reliability of existing questionnaires. Thus, it is imperative that the psychometric properties of questionnaires, including, if applicable, cross-cultural validity, are evaluated, to ensure that the information obtained in a study is valid and reliable and can thus be used to assist in decision-making.

Questionnaires used within a refugee setting

Despite the magnitude of the humanitarian crisis that affects every continent [75], research to evaluate ACEs with standardised tools in refugee children is negligible. Only two questionnaires were used to measure ACEs in refugee children. The questionnaires used were the ICAST-P and ICAST-C, tools developed through a global collaborative effort guided by the International Society for the Prevention of Child Abuse & Neglect (ISPCAN). The ICAST questionnaires are ISPCAN's effort to provide a common tool for systematically comparing recorded incidences of all types of violence against children across cultures and time, in order to provide a more accurate and representative picture of the global problem [39]. Since the ICAST is a global endeavour it has been translated and tested in at least 20 languages [39]. In this review, the ICAST-P was used in Arabic in Palestine and the ICAST-C was used in Kinyarwanda for Rwanda and Dinka and Nuer for Uganda.
The study which used the ICAST-P, a tool with 39 questions in total, aimed to assess the prevalence of child abuse in the West Bank, of which 30.4% of the participants were refugees, and to determine some of its social and political associated factors [47]. The ICAST-P only measures three (emotional and physical abuse and neglect, economic hardship and sexual abuse) of the adversity forms depicted in Table 4 and does not address a single refugee-specific adversity [39], however that was not the goal of the identified study.
On the other hand, the study using the ICAST-C (a questionnaire with 61 items) aimed to understand patterns of violence against children in refugee camps, and associations with adverse mental health outcomes [46]. While the ICAST-C does address a refugee-specific adversity form (using only one question regarding the exposure to war/conflict), and six further adversity forms relevant to refugee children, as illustrated in Table 4, it still overlooks important struggles refugees may experience pre-flight, during flight, and post-flight specifically discrimination and economic hardship.
With a continuously growing refugee population, and previous research suggesting mental and physical health disorders related to traumatic experiences refugee children encounter [76], incorporating the adversities affecting their wellbeing into ACE questionnaires becomes highly important.

Limitations and strengths

This is the first systematic review evaluating whether and to what extent existing ACE questionnaires can be used to identify the adversities of refugee children. However, a few limitations affect this review: Some existing questionnaires might not have been identified because our search was limited to articles published in English, thus limiting the international scope of the review. Additionally, articles were excluded if some respondents were outside the desired age range because they did not fit the definition of a child, thus inferring that the questionnaire is not explicitly designed for children. This review may also be subjected to publication bias, as searches outside the mentioned databases were not made. A final limitation is that information about the modifications made by certain studies to the original version of questionnaires were not collected.
Despite these limitations, we were able to use explicit methodology to identify 14 questionnaires on a global level that assess at least one refugee-specific ACE in children. The results provide a detailed overview of assessed forms of adversities categorized into domains to assist future researchers in identifying useful questionnaires. Additionally, this review draws attention to the existing gaps and the need for a questionnaire that addresses the unique adversities of refugee children.

Conclusion

This review shows that regardless of the availability of numerous questionnaires there is no one-size-fits-all measure for every situation. It also illustrates that there is a need for further psychometric development for most measures. However, the most important finding is that that there is a need to incorporate adversity measures for the most vulnerable populations, specifically refugee children. Existing questionnaires are limited in terms of the extent they address refugee adversities. Given the importance and seriousness of ongoing crises that result in the displacement of children, inclusion of adversities relevant to refugees will allow for further understanding of how ACEs affect these children’s wellbeing and enable the identification of those at risk.
