The Effectiveness of Two Grammar Treatment Procedures for Children With SLI: A Randomized Clinical Trial

Purpose This study compared the effectiveness of two grammar treatment procedures for children with specific language impairment. Method A double-blind superiority trial with cluster randomization was used to compare a cueing procedure, designed to elicit a correct production following an initial error, to a recasting procedure, which required no further production. Thirty-one 5-year-old children with specific language impairment participated in 8 small group, classroom-based treatment sessions. Fourteen children received the cueing approach and 17 received the recasting approach. Results The cueing group made significantly more progress over the 8-week treatment period than the recasting group. There was a medium–large treatment effect in the cueing group and a negligible effect size in the recasting group. The groups did not differ in maintenance of treatment effects 8 weeks after treatment. In single-subject analyses, 50% of children in the cueing group and 12% in the recasting group showed a significa...
