Tablet-based adaptation and administration of the Castles and Coltheart Reading Test 2 for a large longitudinal study

Tablet-adapted measures provide an efficient, accurate method of data collection for large-scale studies. The Castles and Coltheart Reading Test 2 (CC2) is a standardized paper-and-pencil measure of children’s reading ability. In the current study, the CC2 was administered to 603 children aged 7–8 years via iPad using electronic data capture software. Results indicate the tablet-adapted measure could be reliably administered by non-clinical staff and showed quantitative equivalence, i.e., comparable score distributions, to CC2 normative data. Internal consistency was good for regular and non-word lists. Findings suggest that the tablet-adapted CC2 is a viable tool for large research studies.
