Brief summary

The AQUA© questionnaire developed in 2008 is a validated tools for the screening of allergic diseases in adult athletes. The objective of the present study is to develop and validate a modified version of the AQUA© questionnaire to be used in childhood. In this phase, the validation is intended to assess the reliability of the information collected through the AQUA© modified version: question difficulty and response patterns with respect to children characteristics (in particular age, sex and physical activity). In particular, the focus will be on the core questions, i.e. the indicators of allergic disorders. This is a cross-sectional study on 1264 healthy schoolchildren aged 8 to 14 years.

Design outcomes

Primary

Measure	Time frame	Description
Question difficulty	Study end (4 months)	Comprehensibility (or difficulty) of the questions, especially the core questions, will be assessed by the percentages of non-response possibly stratified by children characteristics (in particular age, sex and physical activity).

Secondary

Measure	Time frame	Description
Patterns of missing response	Study end (4 months)	Possible tendency to skip consecutive questions will be assessed by studying the association between the presence of missing (0 = answer missing, 1 = answer given) in sequence (tetrachoric correlation).
Patterns of non-missing responses	Study end (4 months)	Analysis of the distribution of non-missing responses, possibly stratified by children characteristics (in particular age, sex and physical activity).
