AB The paper version of CARAT (pCARAT) is valid to assess asthma control over a 4-week period. For follow-up purposes, assessment through mobile apps (aCARAT) or telephone (tCARAT) may be useful alternatives. We explored the psychometric properties of the aCARAT and tCARAT.Patients with asthma were recruited at secondary care outpatient clinics. During medical visits, patients filled in the pCARAT and were invited to complete the aCARAT in the following days using the app of project Inspirers (InspirerMundi). After 1 week, tCARAT was collected. Patients completing the 3 CARAT versions within 28 days were analysed. CARAT scores (0-worst, 30-best) were calculated. The internal consistency (Cronbach’s α), convergent validity (Spearman correlation-rs) and reliability (intraclass correlation coefficient-ICC, Bland-Altman analysis) were determined.55 patients (21 male; median 19 [interquartile range 17-37]y) were included. The aCARAT was completed by 82% of patients within 1 week of pCARAT; and by 78% within 1 week of tCARAT. The median pCARAT score was 21[17-24], the aCARAT 21[18-26], and the tCARAT 23[21-26]. Internal consistency was good for all versions (α=.73-.77). pCARAT was more strongly correlated with aCARAT than with tCARAT. Reliability was better for aCARAT than for tCARAT (table 1).View this table:Table 1. Psychometric properties of CARAT versions.App and telephonic CARAT versions are valid and reliable, exhibiting comparable psychometric properties to the paper version. These new CARAT versions are promising alternatives for assessing control in patients with asthma.FootnotesCite this article as: European Respiratory Journal 2019; 54: Suppl. 63, PA741.This is an ERS International Congress abstract.
