The questionnaire only proceeded on from this point in the event that at least one trigger food had been selected. Domain 3 focused on the characterisation of the first reaction to suspect food(s), and included questions 3–9. These questions were answered separately for each identified trigger food, and included evaluation of reported symptoms and their severity, definition of the reaction as immediate or delayed, identification of eventual triggers, how the food induced the reaction, and identification of new foods that might have been neglected. Domain 4 included questions 10 and 11 and focused on procedures followed in response to the reaction. Domain 5 involved questions about the stability of reactions upon a new contact. Questions included how long ago the last reaction had taken place (item 12), subsequent ingestion of the suspect food and eventual reactions (item 13), changes in severity or tolerance to the food on subsequent contact (item 14), and the number of new episodes (item 15). Finally, Domain 6 included questions 16 and 17, on personal and family history of allergy, as risk factors.</p><elsevierMultimedia ident="tbl0005"></elsevierMultimedia></span><span id="sec0030" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0060">Initial study</span><p id="par0060" class="elsevierStylePara elsevierViewall">A shortened form of the final questionnaire consisting only of questions on demographics and two questions (questions 1 and 2) regarding the previous occurrence of food reactions and identification of the suspect foods was sent to all children from public Pre-Schools and Primary Schools of the region of Beira Interior (Belmonte, Covilhã and Fundão), Portugal.

This means that we intended to follow a two-step approach for epidemiological studies, also used in EuroPrevall<a class="elsevierStyleCrossRef" href="#bib0310"><span class="elsevierStyleSup">21</span></a> and other studies.<a class="elsevierStyleCrossRefs" href="#bib0305"><span class="elsevierStyleSup">20,31</span></a> Nevertheless, our Q2 screening questionnaire was designed to be applied without the need for the initial Q1 questionnaire. Our full questionnaire involves a semi-structured interview, which makes it more powerful than a simple checklist, and its construction followed a theoretical model, based upon a robust theoretical review of the literature. In addition, it also continued the work of a previously published questionnaire in Brazil,<a class="elsevierStyleCrossRef" href="#bib0320"><span class="elsevierStyleSup">23</span></a> with the addition of questions deemed to be clinically relevant.</p><p id="par0135" class="elsevierStylePara elsevierViewall">With its two initial questions, this questionnaire allows the identification of children with adverse food reactions who may be at risk of developing further reactions. Question 1 aimed at detecting the presence of self-reported adverse reactions to foods and question 2 aimed at identifying the trigger foods. Although these questions are not specific enough to exclude non-allergy related situations, they are potentially highly sensitive, thereby allowing the inclusion of all cases of adverse food reactions which will be more specifically studied by the subsequent items in the questionnaire. In fact, most previously used questionnaires,<a class="elsevierStyleCrossRefs" href="#bib0295"><span class="elsevierStyleSup">18,20,22</span></a> namely those used in EuroPrevall<a class="elsevierStyleCrossRef" href="#bib0310"><span class="elsevierStyleSup">21</span></a> and the Brazilian studies<a class="elsevierStyleCrossRef" href="#bib0320"><span class="elsevierStyleSup">23</span></a> included two similar initial questions.</p><p id="par0140" class="elsevierStylePara elsevierViewall">As far as reliability is concerned, our questionnaire was assessed for intra-observer stability.

All domains showed high levels of concordance, with only two questions in Domain 3 (characterisation of the first reaction) showing a fair concordance Kappa value (question 4, for cardiovascular symptoms; and question 12, regarding how long ago had the previous reaction taken place). Thus, all the remaining 15 questions demonstrated a substantial concordance (Kappa value<span class="elsevierStyleHsp" style=""></span>><span class="elsevierStyleHsp" style=""></span>0.6), and nine questions showed an almost perfect concordance (Kappa between 0.81 and 1). It is difficult to compare these parameters since we could not find any published validation of similar screening questionnaires for food allergies in the literature, apart from the Brazilian study.<a class="elsevierStyleCrossRef" href="#bib0320"><span class="elsevierStyleSup">23</span></a> The Brazilian study showed almost perfect concordance in two questions (“Has your child had any reaction when this food only touched his/her skin?” and “Did your child feel itching, swelling, or numbness in his/her mouth after eating fruit or raw vegetable?”) and this was in agreement with our study.</p><p id="par0150" class="elsevierStylePara elsevierViewall">Our study showed that there was a good concordance in the identification of suspect foods except for fresh legumes, which may be due to the fact that in our population there is a low prevalence of adverse reactions to fresh legumes,<a class="elsevierStyleCrossRefs" href="#bib0325"><span class="elsevierStyleSup">24,25,38</span></a> as has also been reported in other countries.<a class="elsevierStyleCrossRefs" href="#bib0305"><span class="elsevierStyleSup">20,22</span></a> In fact, allergy to legumes is not regarded as a common food allergy.<a class="elsevierStyleCrossRef" href="#bib0260"><span class="elsevierStyleSup">11</span></a> Furthermore, whenever reactions to fresh legumes were reported in our study, these were mild or mostly based upon a single episode of symptoms, which may make it more difficult for the reaction to be remembered, as was demonstrated in a previous study on cow's milk allergy/intolerance.<a class="elsevierStyleCrossRef" href="#bib0400"><span class="elsevierStyleSup">39</span></a></p><p id="par0155" class="elsevierStylePara elsevierViewall">In terms of characterisation of the first reaction (Domain 3), although most parents did not know whether it coincided with the first ingestion of the suspect food (question 3), we still found a good concordance in replies to this question (0.77), with values that were higher than those reported in the Brazilian questionnaire (0.55).<a class="elsevierStyleCrossRef" href="#bib0320"><span class="elsevierStyleSup">23</span></a></p><p id="par0160" class="elsevierStylePara elsevierViewall">Still in Domain 3, answers concerning clinical characterisation of the reaction showed substantial concordance (≥0.77) except for cardiovascular symptoms (0.48), which may have been due to the fact that these symptoms were very seldomly reported in our sample. In terms of triggers such as physical exercise or medication (question 8), all answers were “I do not know” which, in spite of full concordance, did not allow us to further study this aspect. Thus, although these triggers are regarded as relevant in other studies,<a class="elsevierStyleCrossRef" href="#bib0350"><span class="elsevierStyleSup">29</span></a> we could not demonstrate that in our patients.</p><p id="par0165" class="elsevierStylePara elsevierViewall">In Domain 4 (procedure followed after reaction), questions regarding going to hospital as well as medication given, are useful for assessing the severity of the reaction, and showed an almost perfect level of concordance (0.83 and 0.87, respectively), thereby suggesting that there may be a sharper memory of issues of greater frequency or severity.<a class="elsevierStyleCrossRef" href="#bib0400"><span class="elsevierStyleSup">39</span></a> These high levels of concordance were higher than those found in Brazilian children, in similar questions,<a class="elsevierStyleCrossRef" href="#bib0320"><span class="elsevierStyleSup">23</span></a> possibly because the reactions involved were of lower magnitude.</p><p id="par0170" class="elsevierStylePara elsevierViewall">In Domain 5 (stability of reactions upon new contact), concordance was also almost perfect (Kappa value of 0.88) for answers about the number of adverse food reaction episodes. This is possibly because we narrowed parent choice by allowing them to choose from a range of numbers of episode rather than by asking them to fill in a single absolute number of episodes.</p><p id="par0175" class="elsevierStylePara elsevierViewall">Still in Domain 5, in terms of time elapsed since the previous reaction (question 12), we only found a moderate concordance value (Kappa of 0.56), which was, nevertheless, higher than that observed in the Brazilian children (Kappa of 0.28).<a class="elsevierStyleCrossRef" href="#bib0320"><span class="elsevierStyleSup">23</span></a> Questions that deal with elapsed time and age of occurrence may show a low degree of concordance, due to memory bias. In fact, memory of the previous episode may depend upon the severity of the event and time elapsed ever since.<a class="elsevierStyleCrossRefs" href="#bib0335"><span class="elsevierStyleSup">26,39</span></a> Another reason may be that these reactions may include both food-induced allergies as well as non-allergic adverse food reactions with different degrees of severity. In addition, after the initial interview, parents may have attempted to remember the episodes in order to give a more precise reply on retest. Finally, children may have developed tolerance to foods between test and retest as was demonstrated in similar studies in children.<a class="elsevierStyleCrossRefs" href="#bib0400"><span class="elsevierStyleSup">39,40</span></a></p><p id="par0180" class="elsevierStylePara elsevierViewall">In Domain 6 (assessment of risk factors), questions 16 and 17, which aimed at assessing risk factors, only showed good Kappa values (0.64 for other allergic symptoms, and 0.79 for history of allergies in the family). This may be partially explained by the fact the parents of some children may have become more aware that their children had an allergic disease or had a confirmed diagnosis of allergic disease between test and retest, as happened in some cases. In addition, low temporal stability may also have been due to a memory bias, as has been previously reported.<a class="elsevierStyleCrossRefs" href="#bib0395"><span class="elsevierStyleSup">38,40</span></a></p><p id="par0185" class="elsevierStylePara elsevierViewall">Our study has some limitations. Firstly, content validity was only assessed in twenty-four children with food allergies, which is a relatively low number of individuals. Nevertheless, a similar analysis was also performed in 50 children with suspected food allergies. Thus, we believe that the sample size used for this study may have been adequate according to item analysis recommendations<a class="elsevierStyleCrossRef" href="#bib0410"><span class="elsevierStyleSup">41</span></a> Secondly, although most questions had very good consistency and reproducibility, some of the questions had low consistency and will need to be reformulated or removed by multiplex reduction analysis. Thirdly, reliability analysis of the questionnaire using alfa Cronbach's test was not carried out because the intrinsic nature of the items of the instrument did not allow it.<a class="elsevierStyleCrossRef" href="#bib0390"><span class="elsevierStyleSup">37</span></a> Fourthly, the time lag between test–retest was moderately outside the ideal time range (two weeks), although the median in our study was only three weeks, and the mean was five weeks, which is similar to other reports. Nevertheless, this time lag may have been associated with memory bias. In addition, our questionnaire will subsequently have to be validated regarding its sensitivity and specificity by comparing it to the gold standard technique of DBPCFC. Although our 24 children with DBPCFC-confirmed food allergy filled in the questionnaire, we did not perform such an analysis at this stage. Finally, although our questionnaire is simple and was used for screening children for adverse food reactions and food allergies, it may still be further improved by introducing Likert-type questions to increase its robustness for detecting specific food allergy profiles. Further studies are warranted, namely in collaboration with the Brazilian questionnaire.<a class="elsevierStyleCrossRef" href="#bib0320"><span class="elsevierStyleSup">23</span></a></p><p id="par0190" class="elsevierStylePara elsevierViewall">Nevertheless, our questionnaire has the advantage of being simple to use, easily available, and follows criteria for diagnosis of food allergy.<a class="elsevierStyleCrossRefs" href="#bib0225"><span class="elsevierStyleSup">4,10,21</span></a> This is particularly relevant in terms of its application for a rapid and simple diagnosis of possible food allergy in children, a population in which such a problem is highly relevant.<a class="elsevierStyleCrossRefs" href="#bib0240"><span class="elsevierStyleSup">7,11</span></a></p><p id="par0195" class="elsevierStylePara elsevierViewall">Thus, we believe our questionnaire may subsequently be applied in all Portuguese-speaking countries (250 million people) and has features that allow its application worldwide, given its availability, ease of application, global consistency and temporal stability.</p></span><span id="sec0075" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0105">Conclusions</span><p id="par0200" class="elsevierStylePara elsevierViewall">We have developed the first questionnaire in Portugal for screening food allergies in children, which has very good internal consistency and reproducibility and can be easily applied.
