Efficacy of ABRACADABRA literacy instruction in a school setting for children with autism spectrum disorders.

BACKGROUND

There is evidence indicating that instruction using ABRACADABRA (ABRA) - a free web application designed to promote literacy development - may benefit children with autism spectrum disorders (ASD) when administered on an individualized basis in children's homes.

AIMS

Here, we investigated the efficacy of ABRA instruction administered in small groups of children with ASD within a school setting.

METHODS AND PROCEDURES

Children were aged 5.83-8.42 years (n = 23). Some children were assigned to an instruction group and received a minimum of 20 h of ABRA instruction over 9 weeks (n = 11). The other children comprised an age- and ability-matched control group (n = 12) and received business as usual literacy instruction. Outcome measures included word-level accuracy, passage-level accuracy, and passage-level comprehension, all assessed using standardized tests that were independent of ABRA.

OUTCOMES AND RESULTS

ANOVAs comparing pre- versus post-instruction raw scores showed statistically significant improvements in word- and passage-level reading accuracy for the instruction group relative to the control group, with large effect sizes. Gains in reading comprehension for the instruction group were not statistically significant and, in a posthoc correlational analysis, appeared to be related to children's socialisation skills (r = .62).

CONCLUSIONS AND IMPLICATIONS

Literacy instruction using ABRA is associated with improvement in reading accuracy for children with ASD when administered in small groups within a school setting. Children with ASD may require additional supports to make gains in reading comprehension when literacy instruction using ABRA is delivered in groups.
