3.4 Reliability of Tr-PedsQLTM 3.0 EoE Module
The teens self-report and parent proxy-report scales on the EoE Module
demonstrated good internal consistency (Cronbach-α: 0.61-0.90). All of
the ICCs were within good to excellent test-retest reliability range
(0.713-0.935) for both patients and parents. ICCs between teens and
parent reports are in the moderate to good agreement (0.477-0.794) for
the Tr-PedsQL™ EoE module scales (Table 4).
