Validation and acceptability of the mobile app version of the Control of Allergic Rhinitis and Asthma Test for Children (CARATKids)

Résumé fourni par la source

We aimed to validate the electronic version of CARATKids against the gold standard paper-based version. A cross-sectional study was conducted between April and December 2024 in a tertiary hospital in northern Portugal. Children with asthma and/or allergic rhinitis (AR) and their caregivers were recruited during pulmonology outpatient appointments. CARATKids comprises 13 yes/no questions, 8 addressed to the child and 5 to the caregiver (total score 0-13). The electronic CARATKids was implemented in a mobile app. Both paper and electronic versions were administered in a randomized order before and after the appointment. Results: Fifty-one children (median 9[Q1-Q3 8–11] years; 57% male) and respective caregivers (41[37-45] years) were included. The median CARATKids total score was similar across the paper (5[3–8]) and electronic (5[3–7]) versions. The internal consistency was 0.79 for the paper version and 0.83 for the electronic version. The reliability between the two versions was excellent (ICC 0.95, 95%CI 0.91–0.97). The Bland-Altman analysis showed strong agreement between the two versions (mean difference 0.04; 95%LoA -1.99-2.07). The Spearman’s correlation between the two versions was 0.95 (p<.001). 63% of children and 61% of caregivers were indifferent to the version used, while 33% and 35%, respectively, preferred the electronic version. The electronic version of CARATKids appears to be equivalent to the paper-based version, with good acceptance by children and caregivers. CARATKids implementation in mHealth technologies has the potential to enhance remote monitoring of children with asthma and AR.
