Cross-cultural Adaptation of the Adverse Childhood Experiences International Questionnaire

ABSTRACT

OBJECTIVE:

To translate, adapt and validate the contents of the Adverse Childhood Experiences International Questionnaire to a Portuguese version, to be used in Brazil, named Questionário Internacional de Experiências Adversas na Infância.

METHODS:

This is a methodological study of cross-cultural adaptation of evaluation instruments presenting the results of semantic equivalence between the original instrument and the adapted version. The semantic equivalence of the instrument involved the following steps: 1) two translations and a synthesis of the translations; 2) two retranslations; 3) validation of contents by eight health workers; 4) synthesis of the retranslations; 5) pre-tests to assess acceptability, understanding and emotional impact of the questions; and, finally, 6) writing of the final version of the instrument.

RESULTS:

the adapted version proved to be easy to apply and to understand and achieved good semantic equivalence when compared to the original version. The psychometric properties of the instrument still need to be evaluated. Limitations and recommendations for improving the instrument and its use are presented.

CONCLUSION:

The process of cross-cultural adaptation of the Adverse Childhood Experiences International Questionnaire resulted in an adapted version to Brazilian Portuguese.

INTRODUCTION

Although the history and documentation of the occurrence of child abuse is not recent11 Martins CBG, Mello-Jorge MHP. Maus-tratos infantis: um resgate da história e das políticas de proteção. Acta Paul Enferm. 2010;23(3):423-8. https://doi.org/10.1590/S0103-21002010000300018

https://doi.org/10.5964/pch.v3i1.63...
, the systematic study of adverse childhood experiences (ACE) has grown in interest in the scientific community since the 1990s, after the publication of the results of the Adverse Childhood Experiences (ACE) Study33 Felitti VJ, Anda RF, Nordenberg D, Williamson DF, Spitz AM, Edwards V, et al.

.

The ACE Study, conducted in San Diego by the Department of Preventive Medicine for Kaiser Permanente® in collaboration with the United States Centers for Disease Control and Prevention (CDC), is considered a milestone in investigation of exposure to child abuse and neglect as a risk factor associated with negative health and wellness outcomes throughout life33 Felitti VJ, Anda RF, Nordenberg D, Williamson DF, Spitz AM, Edwards V, et al. Relationship of abuse and household dysfunction to many of the leading causes of death in adults: the Adverse Childhood Experiences (ACE) Study.

https://doi.org/10.5964/pch.v3i1.63...
. Since its publication, several epidemiological studies have been conducted, emphasizing a growing worldwide concern about the consequences of child abuse, not only immediately, but also in the long term55 Almuneef M, Qayad M, Aleissa M, Albuhairan F. Adverse childhood experiences, chronic diseases, and risky health behaviors in Saudi Arabian adults: a pilot study. Child Abuse Negl. 2014;38(11):1787-93. https://doi.org/10.1016/j.chiabu.2014.06.003

https://doi.org/10.5964/pch.v3i1.63...
.

Adverse childhood experiences can result in morbidity and mortality directly due to violence, though the consequences more often involve emotional, cognitive and behavioral damage that increases the risk of both the development of chronic diseases in adulthood and exposure to risk behaviors in adolescence88 Clemmons JC, DiLillo D, Martinez IG, DeGue S, Jeffcott M. Co-ocurring forms of child maltreatment and adjustment reported by Latina college students. Child Abuse Negl. 2003;27(7):751-67. https://doi.org/10.1016/s0145-2134(03)00112-1
https://doi.org/10.1016/s0145-2134(03)00...
. In this sense, several studies have shown positive and dose-dependent associations between exposure to ACE and coronary heart disease, diabetes, cancer, chronic obstructive pulmonary disease33 Felitti VJ, Anda RF, Nordenberg D, Williamson DF, Spitz AM, Edwards V, et al.

.

A better understanding of the harmful role of ACE can support the direction and implementation of adequate prevention, intervention and treatment strategies, both in the creation of public health, justice and civic policies and in raising awareness, better training and integration of workers involved in fighting ill-treatment in children and adolescents and its consequences2121 Schwanck RH, Silva MRS. Processos que sustentam o enfrentamento da experiência de abuso sexual na infância: um estudo de caso. Cienc Cuid Saude. 2006;5(3):380-8. https://doi.org/10.4025/cienccuidsaude.v5i3.5038
https://doi.org/10.4025/cienccuidsaude.v...
. In this sense, the creation of standardized ACE evaluation instruments is crucial for reliable and valid measures to improve the quality of information.

In the last three decades, several instruments for investigation of ACE have been proposed, encompassing the evaluation of different categories and environmental contexts, with insufficient subsequent verification of their psychometric properties2222 Bernstein D, Fink L. Childhood Trauma Questionnaire: a retrospective self-report. San Antonio, TX: The Psicological Corporation, 1998.242 Oliveira RV, Pais LG. A origem dos maus-tratos: revisão sobre a evolução histórica das percepções de criança e maus-tratos. Psychol Community Health. 2014;3(1):36-49. https://doi.org/10.5964/pch.v3i1.63
https://doi.org/10.5964/pch.v3i1.63...
. We should note that until this article was written, no instruments developed in Brazil had been found, although some have been adapted for use in Brazilian populations2525 Grassi-Oliveira R, Stein LM, Pezzi JC. Tradução e validação de conteúdo da versão em português do Childhood Trauma Questionnaire. Rev Saude Publica. 2006;40(2):249-55. https://doi.org/10.1590/S0034-89102006000200010

https://doi.org/10.5964/pch.v3i1.63...
The wide variety of instruments used has made it difficult to compare the results produced, not only between diverse social contexts, but also between different periods in the same population. In this perspective, the World Health Organization (WHO), in collaboration with the CDC, developed the Adverse Childhood Experiences International Questionnaire (ACE-IQ) to provide a standardized instrument for worldwide evaluation and surveillance of ACE and to enable the creation of worldwide child abuse prevention programs and policies2727 World Health Organization.

https://doi.org/10.5964/pch.v3i1.63...
.

The ACE-IQ was produced to be applied to adults (≥ 18 years) with the goal of identifying and evaluating prior exposure to 13 different categories of ACE, including sexual, emotional and physical abuse, emotional and physical neglect, family violence, alcohol and drug use, mental illness or suicide in the home, family involvement with criminal activity, parental separation or divorce, community violence, collective violence and bullying2727 World Health Organization. Addressing adverse childhood experiences to improve public health: expert consultation; 4-5 May 2009. Meeting Report. Geneva (CH): WHO; 2009 [cited 2018 Aug 15].

https://doi.org/10.5964/pch.v3i1.63...
. It is important to highlight that all ACE research instruments collect retrospective information, subject to memory biases; in addition, survival bias should be considered since serious violence of different sorts can cause the death of victims.

Exposure of children to violence has great relevance in public health because it poses a risk to their full development, with a wide impact on adult life, hence it is necessary to study and compare the epidemiological profiles of affected populations. In Brazil, epidemiological studies of ACE are still scarce, and different evaluation instruments or non-standard questionnaires have been used, which hinders comparability between results and the contrast with international studies. Thus, considering that there is an instrument proposed by the WHO to establish world parameters, it is pertinent to undertake a cross-cultural adaptation of ACE-IQ to be used with the Brazilian population, since the creation and development of new evaluation instruments is a complex process involving several steps to demonstrate satisfactory psychometric properties2929 Moraes CL, Hasselmann MH, Reichenheim ME. Adaptação transcultural para o português do instrumento “Revised Conflict Tactics Scales (CTS2)” utilizado para identificar violência entre casais. Cad Saude Publica. 2002;18(1):163-76. https://doi.org/10.1590/S0102-311X2002000100017
https://doi.org/10.1590/S0102-311X200200...
.

Cross-cultural adaptation is a thorough procedure that analyzes the use of language considering the cultural context and lifestyle of the population to which the instrument is intended. It is necessary to ensure that the original instrument and the one adapted to the new language are equivalent conceptually, semantically, in operation, measurement and items3030 Guillemin F, Bombardier C, Beaton D. Cross-cultural adaptation of health-related quality of measures: literature review and proposed guidelines. J Clin Epidemiol. 1993;46(12):1417-32. https://doi.org/10.1016/0895-4356(93)90142-n

https://doi.org/10.5964/pch.v3i1.63...
.

To provide a standardized ACE evaluation instrument to be used in Brazil, thereby increasing comparability with other studies and contributing to the validation of the new WHO-proposed instrument, a cross-cultural adaptation of the ACE-IQ was undertaken. This paper presents the semantic equivalence of the Portuguese version of the ACE-IQ, named Questionário Internacional de Experiências Adversas na Infância (EAI-QI).

METHODS

The cross-cultural adaptation process (Figure 1) used in this study was based on the methodology used by Reichenheim and Moraes (2007)3232 Reichenheim ME, Moraes CL. Operacionalização de adaptação transcultural de instrumentos de aferição usados em epidemiologia. Rev Saude Publica. 2007;41(4):665-73. https://doi.org/10.1590/S0034-89102006005000035
https://doi.org/10.1590/S0034-8910200600...
and the recommendations for adaptation of the ACE-IQ available on the WHO website3333 Kazi AM, Khalid W. Questionnaire designing and validation. J Pak Med Assoc. 2012;62(5):514-6.,342 Oliveira RV, Pais LG. A origem dos maus-tratos: revisão sobre a evolução histórica das percepções de criança e maus-tratos. Psychol Community Health. 2014;3(1):36-49. https://doi.org/10.5964/pch.v3i1.63
https://doi.org/10.5964/pch.v3i1.63...
. The ACE-IQ was designed to be used both in self-applied format and face-to-face interviews2727 World Health Organization. Addressing adverse childhood experiences to improve public health: expert consultation; 4-5 May 2009. Meeting Report. Geneva (CH): WHO; 2009 [cited 2018 Aug 15].

https://doi.org/10.5964/pch.v3i1.63...
. For the cross-cultural adaptation process, the questionnaire was used in the interview form.

Figure
Flowchart of the process of cross-cultural adaptation of Adverse Childhood Experiences International Questionnaire (ACE-IQ).

The cross-cultural adaptation process was divided into two phases. The first phase consisted in assessing conceptual and item equivalence. This was done by the researchers and the result was an integrative review of the most used instruments over the last 10 years2626 Pereira FG, Viana MC. Instrumentos mais utilizados na avaliação da exposição a experiências adversas na infância: uma revisão da literatura. Saude Debate. 2021;45(129):501-13.. Initially, informal thematic discussions were held at the Center for Studies and Research in Psychiatric Epidemiology at Universidade Federal do Espírito Santo (CEPEP/UFES). The discussions were coordinated by MCV and included masters and PhDs in public health. The goal was to discuss and verify the relevance of the items of the original instrument to collect information on ACE in Brazil's context. The discussions were based on the main questionnaires and inquiries conducted in international and local context, identified by a systematic review study of publications available until 20032424 Roy CA, Perry JC. Instruments for the assessment of childhood trauma in adults. J Nerv Ment Dis. 2004;192(5):343-51. https://doi.org/10.1097/01.nmd.0000126701.23121.fa
https://doi.org/10.1097/01.nmd.000012670...
.

Then, the second phase of cross-cultural adaptation started, consisting in an assessment of semantic equivalence. This phase was subdivided into five stages. Initially (Stage 1), two translations (T1 and T2) of the original instrument were made from English into Portuguese by two independent translators with Portuguese as their mother tongue. One of the translators is medically trained and has experience in the area of violence against women, while the other is trained in nutrition science with professional experience in chronic non-communicable diseases. Still in Step 1, the researchers located the discrepancies in the translations and asked the translators to reach a consensus in order to achieve a summarized version (S1) of the questionnaire in Portuguese (Step 1).

In the second stage (Stage 2), S1 underwent two reverse translations (to English) by independent translators with English as their mother tongue, one by a specialized company (R1) and the other by an English language teacher (R2).

To conduct the third stage (Stage 3), 13 professionals graduated in different areas were invited to compose the expert committee. The invitation was sent by e-mail with a letter explaining the role of the committee, besides brief background information about the ACE-IQ questionnaire and the methods used in the cross-cultural adaptation of instruments. Eight professionals agreed to participate in Stage 3, six of whom had a medical degree, one a psychology degree and one an arts degree specialized in anthropology. The other seven were PhDs in different areas (epidemiology/collective health, physiology, psychiatry, psychopharmacology). The composition of an expert committee on different areas aims to attest to the broad understanding of the questionnaire, considering its applicability for evaluating the general population3535 Rubio DM, Berg-Weger M, Tebb SS, Lee ES, Rauch S. Objectifying content validity: conducting a content validity study in social work research. Soc Work Res. 2003;27(2):94-104. https://doi.org/10.1093/swr/27.2.94
https://doi.org/10.1093/swr/27.2.94...
.

The expert committee was assigned the evaluation of semantic, conceptual and idiomatic equivalence between the original instrument and the two reverse translations in order to verify the literal correspondence of each translated item and evaluate the correspondence with the original meaning, considering the meaning that some words take in the new cultural context where the instrument will be used. The purpose of this process is finding possible errors made in the previous stages and collecting suggestions to better adapt a first version of the questionnaire (Q1) into Portuguese. All committee members had access to the versions produced in each stage (S1, R1 and R2), as well as the original English language questionnaire, for comparison.

The experts were asked to evaluate, for each item and for the questionnaire as a whole, whether the following items were adequate: correspondence of S1 with the original version, relevance/importance, clarity, vocabulary, objectivity, applicability to Brazil's context and instructional sequence of the items. To evaluate these items, a 1 to 4 Likert scale was used (1 = adequate; 2 = adequate with few changes; 3 = adequate with many changes and 4 = inadequate). By analyzing the evaluation of the items made by the expert committee, the content validity index (CVI) was estimated in an adapted manner [where CVI = (number of answers 1 and 2)/(total number of experts)]. A value above 0.8 was considered to be the adequate index 0.83535 Rubio DM, Berg-Weger M, Tebb SS, Lee ES, Rauch S. Objectifying content validity: conducting a content validity study in social work research. Soc Work Res. 2003;27(2):94-104. https://doi.org/10.1093/swr/27.2.94
https://doi.org/10.1093/swr/27.2.94...
. The experts were also asked to evaluate the correspondence of the reverse translations (R1 and R2) of each item in relation to the original questionnaire (1 = unchanged; 2 = few changes; 3 = many changes and 4 = completely changed)3535 Rubio DM, Berg-Weger M, Tebb SS, Lee ES, Rauch S.

https://doi.org/10.5964/pch.v3i1.63...
.

The fourth stage (Stage 4) consisted in producing a summarized version of the reverse translations (RS1) and the Q1 version. The summarized version resulted from the comparison of the two reverse translations evaluated by the expert committee, by a third translator (R3), proficient and fluent in both languages, with medical training and extensive knowledge about the subject of adverse experiences in childhood, as well as a collective health worker (MCV). The Q1 version was then produced considering the evaluation by the expert committee of the adequacy of each item of the questionnaire and their proposals for better adequacy in items considered inadequate, provided that they were relevant to the original context of ACE-IQ by the researchers, according to WHO instructional documents3434 World Health Organization. Adverse Childhood Experiences International Questionnaire (ACE-IQ). Geneva (CH): WHO; 2020 [cited 2020 Jul 19]. Available from: https://www.who.int/publications/m/item/adverse-childhood-experiences-international-questionnaire-(ace-iq)
https://www.who.int/publications/m/item/...
.

The last stage (Step 5) of semantic equivalence was running a pre-test (Pre-Test 1) with the Q1 version in a sample of student volunteers and employees of a graduate program, consisting of nine women and two men, to evaluate acceptability and understanding of the items and the emotional reaction of the respondents to the topics addressed3232 Reichenheim ME, Moraes CL. Operacionalização de adaptação transcultural de instrumentos de aferição usados em epidemiologia. Rev Saude Publica. 2007;41(4):665-73. https://doi.org/10.1590/S0034-89102006005000035

. The age of the participants ranged from 28 to 48 years, and schooling ranged from high school to doctorate. The questionnaire (Q1) was applied in a standardized manner, in face-to-face interviews conducted by one of the researchers (FGP).

The interviewees used an adapted2525 Grassi-Oliveira R, Stein LM, Pezzi JC. Tradução e validação de conteúdo da versão em português do Childhood Trauma Questionnaire. Rev Saude Publica. 2006;40(2):249-55. https://doi.org/10.1590/S0034-89102006000200010
https://doi.org/10.1590/S0034-8910200600...
numerical verbal scale to evaluate how easy it was to understand each item of the questionnaire. The guiding question for all items was “Did you understand what was asked?”, with three possible answers, as follows: 1 = I did not understand anything; 2 = I understood, but I have questions; 3 = I understood perfectly and have no questions. Respondents were also asked to explain what they understood about each item of the questionnaire in order to assess whether each question replicated the meaning of the original item. At the end of the questionnaire, the participants answered the following questions, still in a face-to-face interview with the researcher (FGP): a) do all the items of the instrument have satisfactory answer options?; b) are you familiar with the terms used?; c) do you find any terms or passages ambiguous or difficult to understand?; and d) regarding the items you did not understand, or in a general way, would you like make any suggestions for improving the questionnaire? The questions were open-ended, and all the answers were explored and noted.

The comments and questions collected in this stage were considered in the making of a second version (Q2), presented to ten new volunteers, eight women and two men. This group was composed of students and employees aged between 19 and 42 years from a public health graduate program, with education ranging from the technical high school to doctorate. The participants read the questionnaire aloud in face-to-face interviews and explained what they understood about each item (pre-test 2). The Q2 version was then adjusted and the final version of the ACE-IQ, adapted for use in Brazil, was produced. It was named “Questionário Internacional de Experiências Adversas na Infância (EAI-QI)”, available in Chart. The numbering and coding of all items was kept as in the original instrument to facilitate the comparison with other studies and the compilation of multiple databases (Chart).

Ethical Procedures

Authorization to undertake the process of cross-cultural adaptation of the ACE-IQ was requested to the WHO violence prevention coordinator, and granted via e-mail.

The ACE-IQ cross-cultural adaptation project was approved by the Research Ethics Committee of the UFES Health Sciences Center (CEPE/UFES 2,141,917). All participants signed the informed consent form.

RESULTS

The first and last versions of the questionnaire are shown in Table with the original English language version of the instrument, in the first column.

Table
Questionnaire items that presented criteria with CVI below 0.7 in the evaluation by the expert committee.

Only three of the 43 items of both reverse translations, when compared by the expert committee to the original instrument, were considered to have “many changes” or “completely changed”. The discrepancies found occurred in the categories of self-declared race/color (item C4), education (C5) and occupation (C6), and were resolved by R3, according to the terms standardized by the Brazilian Institute of Geography and Statistics (IBGE). These differences had already been identified in the two initial translations. Still regarding the reverse translations, the other items were considered by the experts as “unchanged” or with “few changes”, and R2 was considered more adequate in relation to R1 regarding correspondence to the original version. All items were reviewed and, when necessary, adjusted by R3.

In the overall evaluation of the questionnaire, the CVI corresponded to 1.0 in almost all the criteria judged by the expert committee, considering the correspondence of S1 with the original version in relation to relevance/importance, clarity, vocabulary, objectivity, applicability to Brazil's context and instructional sequence of the items. Of the 43 items, only two (C4 and A6) had CVI < 0.7 (Table), requiring adjustment by R3 in both RS1 and Q1. In item C4, the experts recommended the inclusion of the answer option “others”, considering that some people may not identify with the alternatives presented. In item A6, referring to sexual abuse, the experts showed several formats for rewriting the item to emphasize the idea that the respondent was “forced” to something they did not want; however, when the original question was submitted to the pre-test, there were no interpretation difficulties; therefore, the suggestions for modification made by the expert committee were not put into practice. Generally, 73% of the evaluated criteria received the maximum score in the CVI (1.0); in 21% the CVI was 0.87; and in 4%, 0.75. Values > 0.83333 Kazi AM, Khalid W. Questionnaire designing and validation. J Pak Med Assoc. 2012;62(5):514-6. were considered adequate. Despite this satisfactory score, all the suggestions made by the experts were considered and, when possible and relevant, incorporated into Q1.

Pre-Test 1

In the first pre-test, conducted with 11 participants, items P3 and V2 had the lowest comprehension averages (2.72), evaluated by the three-point verbal scale.

Item P3, which evaluates the non-provision of an adequate diet, was mistakenly interpreted by some respondents as being due to parents or guardians being unable to afford it, but physical neglect involves the non-provision of basic conditions for child development (food, clothing, medical care) when there is no economic adversity3737 Vilagut G, Saunders K, Alonso J. World mental health survey methods for studying mental-physical comorbidity. In: Von Korff MR, Scott KM, Gureje O, eds. Global Perspectives on Mental-Physical Comorbidity in the WHO World Mental Health Surveys. New York: Cambridge University Press, 2009. p. 29-50.. A similar interpretation occurred in item P5 (mean 2.82), in which, besides financial struggling, the impossibility of accessing, or local unavailability of, schools was suggested.

Item V2 was resolved by adding instructions for choosing only one alternative concerning the most frequent form of bullying, as the respondents tended to check more than one answer.

Item A3 was discussed among the researchers after the participants in pre-Test 1 pointed out that the expression “slapped” (among all other forms of aggression) might not mean serious physical aggression or, still, that such situations described in the item could be understood as a form of disciplinary correction instead of physical abuse. This result led to consideration and recommendations suggested by the researchers (see “Limitations of the instrument and recommendations”).

In items A5 to A8, all respondents who suffered sexual abuse expressed confusion about what was being evaluated, that is, whether the abuse was restricted to the home environment and, consequently, was committed by family member(s), or whether it included any and all sexual abuse suffered. This was because in this section, there was an abrupt and unexplained change in the way the questions were designed, compared to the previous sections. These were preceded by the phrase “[Has] any of your parents or guardians or someone who lived at your house…?”, and, in the section on sexual abuse, the introductory phrase became “[Has] anyone…”, without any specification as to the offender. According to the guidelines for using the ACE-IQ3434 World Health Organization. Adverse Childhood Experiences International Questionnaire (ACE-IQ). Geneva (CH): WHO; 2020 [cited 2020 Jul 19]. Available from: https://www.who.int/publications/m/item/adverse-childhood-experiences-international-questionnaire-(ace-iq)
https://www.who.int/publications/m/item/...
, these items evaluate child sexual abuse committed by any person – family members, acquaintances or strangers to the child. To solve this difficulty and clarify the possible questions, the researchers decided to change the introductory question so that the four questions in this section were preceded by the phrase “[Has] any of your parents or guardians, or someone who lived at your house, or anyone known or unknown…”. A sub-item was also included in each question to distinguish whether or not the abusers were residents of the house (see “Limitations of the instrument and recommendations”).

The participants in Pre-Test 1 made some suggestions: 1) changing the order of item C5 from “Qual é o seu mais alto nível de escolaridade?” to “Qual o seu nível de escolaridade mais alto?”; (2) having only one choice for work situation in the last 12 months (C6), even though they found it difficult to choose only one answer; and 3) adjusting the instructions before domestic violence section (6-8), removing the word “things”, and the excerpt “not necessarily to you”; (4) replacing the word “hit” with “attacked” in the F8 key; and 5) removing the phrase “exposure to war” to include the terms “shootings and drug trafficking” in the instructions preceding the questions about collective violence (7–10).

A final item was also included in the questionnaire – “Throughout your growth period, in the first 18 years of your life, did you experience any other traumatic events that were not mentioned in the interview?” – if so, a blank space to answer (see “Limitations of the instrument and recommendations”).

Pre-Test 2

All the adapted items and the changes suggested in the results of Pre-Test 1 aimed at using colloquial terms used in Brazil's context, which are easily understood by the general population, thus giving rise to a modified version of the questionnaire (Q2), which was evaluated in Pre-Test 2. Based on the respondents’ reading and comprehension of each item, modifications to the text were requested when the contents differed from the original version. They also suggested modifications when they thought that the question could be better formulated.

After Pre-Test 2, the researchers decided to modify part of the P3 items (“… even if they could easily offer you some food?”) and P5 (“… even if they had an obligation to do it?”) so that the question could be more easily understood (Table).

Item C6 was tested in two formats: 1) allowing the choice of all the options describing the respondent's work situation in the last 12 months; and 2) allowing only one answer describing the respondent's main work/occupation. Although the instructions in the original questionnaire require only one answer, the researchers opted to use multiple choices considering the difficulty in choosing only one answer in Pre-Test 1, perhaps reflecting the fact that having more than in job is common in Brazil. Other small changes were made after Pre-Test 2 and incorporated into the final version of the instrument, as presented in the Table.

DISCUSSION

The use of standardized evaluation instruments has become a necessary practice in health sciences as a way of improving scientific knowledge. Systematized data collection reduces divergence, increases the quality of information and, as a result, allows the results to be compared. Furthermore, it produces a better basis for planning public policies and clinical conduct3131 Beaton DE, Bombardier C, Guillemin F, Ferraz MB. Guidelines for the process of cross-cultural adaptation of self-reported measures. Spine. 2000;25(24):3186-91. https://doi.org/10.1097/00007632-200012150-00014
https://doi.org/10.1097/00007632-2000121...
.

Structured questionnaires are widely used instruments in epidemiological research in several areas of interest. Before considering the development of any new evaluation method, a rigorous literature review is needed to identify the existing instruments that allow the desired evaluation of the study object3333 Kazi AM, Khalid W. Questionnaire designing and validation. J Pak Med Assoc. 2012;62(5):514-6.. Regarding traumatic events experienced in childhood, a variety of instruments are available2424 Roy CA, Perry JC.

. When identifying a suitable instrument for the objectives of the study that is not available in the language of the population to be studied, the best alternative would be to start a cross-cultural adaptation3838 Harkness JA, Schoua-Glusberg A. Questionnaires in translation. In: Harkness J, editor. Cross cultural survey equivalence. Mannheim (DE): Zentrum für Umfragen, Methoden und Analysen -ZUMA; 1998 [cited 2018 Aug 15].

.

Launching the ACE-IQ for use in Brazil, through the cross-cultural adaptation process described here, will allow the use of a WHO instrument that enables the investigation of a greater number of ACE than other instruments in Portuguese. It is aimed at setting up structured evaluations and producing comparable measures between several countries with a view to building epidemiological profiles of exposure to adversity and traumatic events in childhood.

This article presents the semantic equivalence of the ACE-IQ of the Portuguese language version currently in use in Brazil. Cross-cultural adaptation is a painstaking process, and semantic equivalence is considered only one of its stages3232 Reichenheim ME, Moraes CL. Operacionalização de adaptação transcultural de instrumentos de aferição usados em epidemiologia. Rev Saude Publica. 2007;41(4):665-73. https://doi.org/10.1590/S0034-89102006005000035
https://doi.org/10.1590/S0034-8910200600...
, although there is no consensus on the most appropriate way of undertaking cross-cultural adaptation, and several methodological approaches have been proposed3030 Guillemin F, Bombardier C, Beaton D. Cross-cultural adaptation of health-related quality of measures: literature review and proposed guidelines. J Clin Epidemiol. 1993;46(12):1417-32. https://doi.org/10.1016/0895-4356(93)90142-n

Content validity was presented as part of semantic equivalence, consisting in a judgment of the representativeness and clarity of each item of the instrument according to pre-established criteria. Concordance between the judges was evaluated regarding adequacy of the content to what the instrument is designed to measure3535 Rubio DM, Berg-Weger M, Tebb SS, Lee ES, Rauch S.

https://doi.org/10.5964/pch.v3i1.63...
, not exempting, however, the evaluation of other psychometric measures4545 Pasquali L. Psicometria. Rev Esc Enferm USP. 2009;43 N° esp:992-9. https://doi.org/10.1590/S0080-62342009000500002
https://doi.org/10.1590/S0080-6234200900...
. Good semantic equivalence was found between the Portuguese language version and the original by content validity, considering the evaluation by the expert committee and the estimation of the CVI and average intelligibility during the pre-tests.

This study should be considered in light of some limitations. The pre-tests were performed on volunteer samples not representative of the general Brazilian adult population, therefore the understanding of items or expressions may vary in samples with a distinct distribution of age, education or socioeconomic class, which can be assessed in later studies, when the questionnaire produced will be applied to other samples. The original instrument features some idiomatic expressions with no direct equivalents in Brazilian Portuguese, which required an extensive search for close alternatives between the respondents and the expert committee. Evaluating community and collective violence involves multiple aspects, usually dependent on the socio-cultural context of the investigated population and the socioeconomic/political context of the region/country, as there are items which are not relevant to the Brazilian population, such as exposure to war situations, terrorism, genocide, political and ethnic conflicts, among others. On the other hand, the investigation of community violence, extremely relevant in Brazilian studies, associated with the presence of drug trafficking and cartel and/or police actions, particularly in socially vulnerable regions directly exposed to gang fights and stray bullets, was included in the ACE-QI as collective violence. Therefore, these contexts converge in the evaluation of some sections of Brazil's population.

Limitations of the Instrument and Recommendations

The instrument adapted in this study, like most instruments for evaluating ACE, was designed to investigate exposure to ACE in adults (aged ≥ 18 years), so memory biases may occur in data information. In addition, individuals exposed to more severe violence have increased risk of death and, therefore, the most severe spectrum of exposure cannot be captured by this form of assessment.

The ACE-IQ incorporated the investigation of other kinds of exposure, such as bullying and collective or community violence, to the study of ACE. Although more comprehensive in identifying ACE, and very useful in epidemiological research, the instrument has limitations in the way it evaluates some ACE. Therefore, it is pertinent to present some considerations and recommendations regarded as relevant both for improving the instrument and for guiding its use, analysis and interpretation of results in studies using the ACE-IQ. They are the following:

  1. Age: all questions are preceded by an introductory sentence determining that only experiences which occurred” during the growth period, up to 18 years of age” are to be considered. Exposure to ACE may have a harmful differential impact depending on the age in which it happened. Young children are more physically fragile, more powerless to confront violence, more vulnerable to neglect and less capable of understanding of what is happening around them. On the other hand, adolescents tend to suffer mistreatment more intensely and severely than younger children, but they may also be able to cope with it, and/or avoid it, to some extent. Therefore, we suggest that ACE be investigated in at least two distinct age periods, childhood (up to 10 years) and adolescence (from 11 to 18 years). In addition, duration of exposure to ACE also has a direct implication on the negative consequences and should be included in the questionnaire.

  2. Severity of physical abuse: in question A3, there are expressions that involve varying degrees of physical aggression (from “slapped” to “kicked” “punched” and “hit”), which generates confusion when answering since some forms of mild physical aggression can be culturally justified as disciplinary methods. An attempt to solve this difficulty was removing the expression “slapped”. Physical abuse of a child is defined as “the intentional use of physical force that results, or is highly likely to result, in damage to the child's health, survival, development, or dignity”33 Felitti VJ, Anda RF, Nordenberg D, Williamson DF, Spitz AM, Edwards V, et al. Relationship of abuse and household dysfunction to many of the leading causes of death in adults: the Adverse Childhood Experiences (ACE) Study. Am J Prev Med. 1998;14(4):245-58. https://doi.org/10.1016/s0749-3797(98)00017-8
    https://doi.org/10.1016/s0749-3797(98)00...
    ,462 Oliveira RV, Pais LG. A origem dos maus-tratos: revisão sobre a evolução histórica das percepções de criança e maus-tratos. Psychol Community Health. 2014;3(1):36-49. https://doi.org/10.5964/pch.v3i1.63
    https://doi.org/10.5964/pch.v3i1.63...
    . Thus, we suggest adding sub-items to classify the degree of aggression (mild, moderate, intense or very intense) and to produce more robust estimates about child physical abuse.

  3. Perpetration of sexual abuse: items A5-A8 present an abrupt change in the format of questions investigating the occurrence of sexual abuse, since all previous items were strictly related to the family environment. We suggest adding an introductory sentence to the session to clarify that the objective of this module is to investigate sexual abuse occurring before the age of 18 and perpetrated by any person, known or not to the victim. We also suggest adding a sub-item to all questions to identify whether or not the perpetrator is a resident of the household, as this information is relevant for understanding the impact of the various types of sexual abuse perpetrated against children and adolescents. Sexual abuse in the domestic environment tends to be repetitive, and the child is initially unaware and unable to discern the abuse. Thus, the perpetrator, who should protect and care for the child or adolescent, tends to benefit from the relationship of trust and power, taking advantage of their vulnerability, immaturity and insecurity to impose sexual assault and silence under threats and/or physical force4747 Abreu CCNB. A infância vitimizada: retratos da violência doméstica contra a criança. Curitiba, PR: Appris; 2016.. Outside the domestic environment, sexual abuse tends to occur occasionally, with the victim being held hostage by the perpetrator only during the assault per se. In any case, sexual abuse is a traumatic phenomenon with serious consequences, and identifying the aggressors can be crucial for the implementation of preventive strategies, besides being clinically relevant for the therapeutic management of victims of sexual abuse.

  4. Bullying: only the most frequent form of bullying is investigated, disregarding the multiplicity and severity of aggressions. In addition, the possibility that the victim is also an aggressor is not investigated, considering that children and adolescents who are victims of ACE can become aggressors, thus perpetuating a cycle of abuse and naturalizing violence in problem-solving. Thus, we suggest allowing multiple choice answers and investigating the perpetration of bullying.

  5. Other types of ACE: understanding about ACE has changed throughout history and, as a result, new categories were defined and explored in the making of new questionnaires. Although the ACE-IQ features a wider range of AEC than the previous instruments, some adversities described in other questionnaires were not included, such as, for example, exposure to economic adversity and occurrence of physical diseases and/or serious accidents. Therefore, we suggest that a final item be included to identify the occurrence of other unevaluated traumatic events.

CONCLUSION

As the instrument adapted in this study showed good semantic equivalence, it was launched in Brazil as a tool for epidemiological research allowing comparability between national and international studies. In addition, it can contribute to scientific knowledge about the harmful impact of ACE on the adult life of the Brazilian population, with great relevance to public health. The systematic investigation of the ACE also has clinical importance as it provides information on the patient's traumatic historical context, enabling a more comprehensive evaluation, more accurate diagnoses and more adequate treatments, thereby reducing health system costs, loss of productivity and personal suffering and disability.

Finally, it can provide relevant information to support the planning and elaboration of public policies for prevention and intervention, aiming to minimize exposure to adverse and traumatic experiences in childhood and adolescence.
