377! improve the questionnaire’s reliability and validity. The 13-item questionnaire showed to have good discriminative properties.
Of the 13 items, five are to be answered by parents and eight by children (Fig. S1). Although this method of a twofold answer was found to be the most adequate solution, the usability of the questionnaire is somehow reduced by the parent and child response method. However, previous studies on asthma also observed divergence between children and parent-reported variables, with some sets of questions being better answered by each of them (11, 13, 14). In fact, cACT also has a twofold answer method (11). The questions on sneezing and other nasal symptoms had better results when answered by the children, while parents may be less aware of the frequency of these symptoms. In the cognitive interviews performed in the initial stages of CARATKids development, this lack of concordance was already observed (7).
The internal consistency was satisfactory (15), being similar or better than other questionnaires evaluating asthma control in children, such as cACT (11), Asthma Control Questionnaire (ACQ) in Children (CAN) (16), Test for Respiratory and Asthma Control in Kids (TRACK) (17), ACQ in children (18), or Asthma Quiz (19) (Table 3); however, it was slightly lower than the one in adult’s questionnaires, as CARAT (20) and Asthma Control Test (ACT) (21) (Table 3). The areas under the curve were high (0.761–0.826), namely when compared with physician assessment of control and cACT (Fig. 2) assumed as
comparators. These are in the same range of those previously observed in studies on adults and are higher than the ones reported for cACT (Table 3).
A gold standard for ARA control has not been established yet. Therefore, concurrent validity was assessed using different external measures of control, based on physicians, children, and caregivers’ assessments. A priori predictions were met, and all coefficients are in the same range as those observed with other tools to assess control, both in children and adults (Table 3).
In test–retest reliability analysis, CARATKids scores showed an ICC similar or better than those of ACQ in children, TRACK, CAN, ACT, and CARAT (Table 3).
Large responsiveness, greater than 0.8 was observed (22). Moreover, the magnitude of GRI of CARATKids (1.51) was similar to the one of CARAT (1.54).
Regarding longitudinal validity, correlation coefficients were higher than a priori predictions for physician and children VAS of both asthma and rhinitis control (Table 2), but not for cACT. As we could not find longitudinal validity assessment of cACT, it is difficult to interpret the low correlation coefficient we observed between DCARATKids scores and DcACT. This low correlation may be related to differences in sensitivities or responsiveness of the question-naires. In any case, in both visits, significant differences were observed in CARATKids scores between cACT control groups (Fig. 1). The only control questionnaires for children with published longitudinal validity results are ACQ in Table 2 Correlation coefficients between CARATKids with external measures of control and of between-visits changes (variation) of CARATKids scores (DCARATKids) and between-visits changes of external measures of control
