To ensure that the sample was representative, we contacted a group of patients with EoE and their parents through the Asociación Española de Pacientes con Esofagitis Eosinofílica (Spanish Association of Patients with Eosinophilic Oesophagitis, AEDESEO) by electronic mail or telephone. We selected patients that accepted to participate by consecutive sampling until we achieved the required sample size established by the Mapi Research Trust.

In the same age group, in the feelings scale, for the question “¿Te preocupa comer algún alimento al que eres alérgico/a o que no deberías comer?” we thought that the expression “te preocupa” may be too abstract and that it would be more understandable for these children if the item read “te da miedo”. In the “how I talk to others” scale, the initial translation was “te cuesta decírselo a…”, but we switched it to “es difícil para ti decírselo a…” to improve comprehension.</p></span><span id="sec0065" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0135">Questionnaire comprehension</span><p id="par0135" class="elsevierStylePara elsevierViewall">We were able to administer the questionnaire to the necessary number of children and parents in each age group. We interviewed a total of 15 patients (13 boys [86.6%] and 2 girls [14.4%]) and 20 parents, of who 14 were mothers. We recruited most parents through the AEDESEO, but we needed to recruit another 2 patients from a primary care caseload and 2 patients from the caseload of the paediatric gastroenterology department of a tertiary care hospital to obtain the necessary number of patients in the younger age group.</p><p id="par0140" class="elsevierStylePara elsevierViewall">The preliminary final version of the questionnaire was completed by every participant during the cognitive interview. All parents and 86% of the children reporting understanding the entire questionnaire well. Forty-six percent of patients and 65% of parents gave suggestions as to the items that needed revising, and 33% of children and 60% of parents suggested specific modifications (<a class="elsevierStyleCrossRefs" href="#tbl0010">Tables 2 and 3</a>).</p><elsevierMultimedia ident="tbl0010"></elsevierMultimedia><elsevierMultimedia ident="tbl0015"></elsevierMultimedia></span><span id="sec0070" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0140">Identified difficulties and modifications made based on patient comprehension testing results</span><p id="par0145" class="elsevierStylePara elsevierViewall">When it came to the item “Me preocupa ponerme enfermo delante de otras personas” (“I worry about getting sick in front of other people”), older children and parents suggested adding some symptoms related to the disease to improve comprehension, and the final item read “Me preocupa ponerme enfermo/a (vomitar, atascarme) delante de otras personas”. Some children in the 5-to-7 years age group expressed difficulties with negative sentences, which translated literally to Spanish involved the use of double negatives, for things that in Spanish, contrary to English, would more frequently be expressed with a positive sentence. We proposed changing the phrasing of the item to switch it to a positive sentence, but after consulting with the authors of the original questionnaire, and given that this issue did not affect all children, we decided to maintain the construction that was used originally.</p><p id="par0150" class="elsevierStylePara elsevierViewall">Some parents had difficulty identifying the symptoms or feelings of their children, especially those in the youngest age group.</p><p id="par0155" class="elsevierStylePara elsevierViewall">Although the instructions provided before administering the questionnaire specified that the items referred to the symptoms, worries and feelings of the children, some parents wondered whether they had to report their own concerns or those of their children.

None of the parents found it long, boring or useless. When it came to the children, 13.4% found it long, 6.7% found it boring and 66.6% found it useful; children aged 5–7 years were unable to tell why the questionnaire could be useful (<a class="elsevierStyleCrossRefs" href="#tbl0010">Tables 2 and 3</a>). Children in this age group asked for their parents’ assistance, even to have the items read to them, despite the express request to not have parents interfere with the responses of the patients. This was the group that took longest to complete the questionnaire and that required the greatest number of clarifications.</p></span></span><span id="sec0080" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0150">Discussion</span><p id="par0165" class="elsevierStylePara elsevierViewall">We carried out the transcultural adaptation to Spanish of the specific PedsQL Eosinophylic Esophagitis Module to allow assessment of the health-related quality of life of Spanish children with EoE. The translation was made following the internationally accepted process of forward and backward translation. After, we assessed the preliminary final version by interviewing patients and their parents with the aim of detecting potential comprehension problems and making the necessary corrections in the definitive version.</p><p id="par0170" class="elsevierStylePara elsevierViewall">The earliest studies that assessed HRQoL in children with EoE<a class="elsevierStyleCrossRef" href="#bib0150"><span class="elsevierStyleSup">13</span></a> used the generic PedsQL questionnaire. They found that children with EoE had a poorer quality of life, especially in the social and psychological areas. The interest in improving HRQoL has stimulated the development of specific questionnaires adapted to different chronic diseases that assess particularities of the disease of interest. Franciosi et al. conducted a study to identify the concerns of children with EoE and their parents,<a class="elsevierStyleCrossRef" href="#bib0130"><span class="elsevierStyleSup">9</span></a> which was the foundation for the development of a specific EoE questionnaire for the paediatric population.<a class="elsevierStyleCrossRef" href="#bib0125"><span class="elsevierStyleSup">8</span></a> There are several versions of this questionnaire for different age groups, which allows adapting the items to the cognitive development of the children. There is also a patient version and a parent proxy version, allowing comparison of the reports of children and the perceptions of the parents, which do not always match.</p><p id="par0175" class="elsevierStylePara elsevierViewall">Most available questionnaires are in English and can only be applied to the population for which they were designed, so their use in a different context requires the translation and transcultural adaptation to the country where it will be applied. Our research group has previous experience in this area, as we performed the transcultural adaptation and validation of a specific questionnaire for assessment of HRQoL in children with coeliac disease developed in the Netherlands (the Coeliac Disease Dutch Questionnaire [CDDUX]).<a class="elsevierStyleCrossRef" href="#bib0155"><span class="elsevierStyleSup">14</span></a></p><p id="par0180" class="elsevierStylePara elsevierViewall">The transcultural adaptation process is complex and must rigorously follow a series of strict stages. In our case, the challenges we met during the process involved the need to adapt the terminology of the questionnaire to the cognitive skills of the age group that it was meant for. The group that had the most difficulty completing the questionnaire was the group of patients aged 5–7 years, for whom it was necessary to adapt the terminology, avoiding abstract concepts that were harder to understand.</p><p id="par0185" class="elsevierStylePara elsevierViewall">We succeeded in recruiting the sample size recommended by the Mapi Research Trust, which was particularly challenging when it came to the 2–4 years and 5–7 years age groups, given the lower frequency of disease in younger children, but allowed us to make an adequate analysis of the questionnaire by age group. Older children can understand and express their difficulties more easily than younger children, and therefore it is important to ensure adequate representation of all age groups.</p><p id="par0190" class="elsevierStylePara elsevierViewall">The cognitive interviewing phase was the hardest from a methodological standpoint, but it allowed us to identify difficulties and limitations in the translated version, especially in the group of patients aged 5–7 years.</p><p id="par0195" class="elsevierStylePara elsevierViewall">Some parents of very young children had difficulty answering some of the questions, due to either children not verbalising certain feelings at a young age or to the difficulty of identifying symptoms and moods in this age group.</p><p id="par0200" class="elsevierStylePara elsevierViewall">The difficulties and suggestions for language changes conveyed by older children and parents were particularly useful in improving the comprehension of the questionnaire, especially as pertained the manifestations of disease, and most of this feedback was incorporated in the final version. This achieves comprehension of the different items by the largest possible number of children and parents. We ought to highlight that despite the instructions specifying that the items referred to either the past month or the past week, both children and parents expressed concerns about what point in the course of illness and treatment the items referred to, which may suggest that they have an interest in expressing how they felt when the disease was at its worst.</p><p id="par0205" class="elsevierStylePara elsevierViewall">The problems we encountered in the transcultural adaptation process were similar to those described by Santos et al., who recently published the adaptation to Portuguese of the Pediatric Eosinophilic Esophagitis Symptom Score (PEES).<a class="elsevierStyleCrossRef" href="#bib0160"><span class="elsevierStyleSup">15</span></a> As occurred in our study, they mainly found difficulties in comprehension in the youngest children. The syntactic and semantic differences were similar in both studies.</p><p id="par0210" class="elsevierStylePara elsevierViewall">We sent the final version to the company that owns the rights to the questionnaire, which, after reviewing the submitted documentation, proceeded to approve it.</p><p id="par0215" class="elsevierStylePara elsevierViewall">One of the main limitations of the study was that many of the patients that participated in the cognitive interview resided in the Madrid metropolitan area, with a predominance of households of middle-to-high socioeconomic status. Also, while we asked parents of the youngest patients not to interfere with their children's responses, they may have somewhat influenced their answers in their attempt to help them understand the most challenging questions, but it is rare for patients aged 5–7 years not to need any form of assistance. In fact, most paediatric HRQoL questionnaires have been developed for children aged 8–18 years.<a class="elsevierStyleCrossRefs" href="#bib0110"><span class="elsevierStyleSup">5,16,17</span></a></p><p id="par0220" class="elsevierStylePara elsevierViewall">The next phase in our project is to validate the Spanish version of this questionnaire, assessing its validity and reliability, to allow its use in Spanish children.</p><p id="par0225" class="elsevierStylePara elsevierViewall">In conclusion, we performed the transcultural adaptation to Spanish of the PedsQL EoE Module, which parents and patients considered a useful instrument in relation to this disease. This questionnaire will be useful for assessing the quality of life if paediatric patients with EoO in the different stages of disease and based on the treatment received, and also for making comparisons with children in other countries where the same questionnaire is used.</p></span><span id="sec0085" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0155">Conflicts of interest</span><p id="par0230" class="elsevierStylePara elsevierViewall">The authors have no conflicts of interest to declare.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:10 [ 0 => array:3 [ "identificador" => "xres1354636" "titulo" => "Abstract" "secciones" => array:5 [ 0 => array:2 [ "identificador" => "abst0005" "titulo" => "Introduction" ] 1 => array:2 [ "identificador" => "abst0010" "titulo" => "Objective" ] 2 => array:2 [ "identificador" => "abst0015" "titulo" => "Methods" ] 3 => array:2 [ "identificador" => "abst0020" "titulo" => "Results" ] 4 => array:2 [ "identificador" => "abst0025" "titulo" => "Conclusions" ] ] ] 1 => array:2 [ "identificador" => "xpalclavsec1245575" "titulo" => "Keywords" ] 2 => array:3 [ "identificador" => "xres1354637" "titulo" => "Resumen" "secciones" => array:5 [ 0 => array:2 [ "identificador" => "abst0030" "titulo" => "Introducción" ] 1 => array:2 [ "identificador" => "abst0035" "titulo" => "Objetivo" ] 2 => array:2 [ "identificador" => "abst0040" "titulo" => "Métodos" ] 3 => array:2 [ "identificador" => "abst0045" "titulo" => "Resultados" ] 4 => array:2 [ "identificador" => "abst0050" "titulo" => "Conclusiones" ] ] ] 3 => array:2 [ "identificador" => "xpalclavsec1245576" "titulo" => "Palabras clave" ] 4 => array:2 [ "identificador" => "sec0005" "titulo" => "Introduction" ] 5 => array:3 [ "identificador" => "sec0010" "titulo" => "Methods" "secciones" => array:3 [ 0 => array:2 [ "identificador" => "sec0015" "titulo" => "Description of the Pediatric Quality of Life Eosinophilic Esophagitis Module" ] 1 => array:3 [ "identificador" => "sec0020" "titulo" => "Transcultural adaptation" "secciones" => array:5 [ 0 => array:2 [ "identificador" => "sec0025" "titulo" => "Forward translation" ] 1 => array:2 [ "identificador" => "sec0030" "titulo" => "Backward translation" ] 2 => array:2 [ "identificador" => "sec0035" "titulo" => "Cognitive interview" ] 3 => array:2 [ "identificador" => "sec0040" "titulo" => "Development of the final version" ] 4 => array:2 [ "identificador" => "sec0045" "titulo" => "Reading test" ] ] ] 2 => array:2 [ "identificador" => "sec0050" "titulo" => "Ethical considerations" ] ] ] 6 => array:3 [ "identificador" => "sec0055" "titulo" => "Results" "secciones" => array:4 [ 0 => array:2 [ "identificador" => "sec0060" "titulo" => "Questionnaire forward and backward translation process" ] 1 => array:2 [ "identificador" => "sec0065" "titulo" => "Questionnaire comprehension" ] 2 => array:2 [ "identificador" => "sec0070" "titulo" => "Identified difficulties and modifications made based on patient comprehension testing results" ] 3 => array:2 [ "identificador" => "sec0075" "titulo" => "Questionnaire acceptability" ] ] ] 7 => array:2 [ "identificador" => "sec0080" "titulo" => "Discussion" ] 8 => array:2 [ "identificador" => "sec0085" "titulo" => "Conflicts of interest" ] 9 => array:1 [ "titulo" => "References" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2019-09-22" "fechaAceptado" => "2020-01-13" "PalabrasClave" => array:2 [ "en" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Keywords" "identificador" => "xpalclavsec1245575" "palabras" => array:4 [ 0 => "Eosinophilic oesophagitis" 1 => "Health-related quality of life" 2 => "Transcultural adaptation" 3 => "Specific quality of life questionnaire" ] ] ] "es" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Palabras clave" "identificador" => "xpalclavsec1245576" "palabras" => array:4 [ 0 => "Esofagitis eosinofílica" 1 => "Calidad de vida relacionada con la salud" 2 => "Adaptación transcultural" 3 => "Cuestionario específico de calidad de vida" ] ] ] ] "tieneResumen" => true "resumen" => array:2 [ "en" => array:3 [ "titulo" => "Abstract" "resumen" => "<span id="abst0005" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0010">Introduction</span><p id="spar0005" class="elsevierStyleSimplePara elsevierViewall">Eosinophilic oesophagitis (EoE) affects the quality of life (QoL) of the patients and their families.
