Two models of grammar facilitation in children with language impairments: phase 2.

Fey, Cleave, Long and Hughes (1993) demonstrated the effectiveness of two 5-month interventions for preschoolers with problems in expressive grammar. This article reports the results of an additional 5-month intervention phase for 18 of the original participants. Results indicated that although participants improved during Phase 2, improvements generally were not as strong as those noted for Phase 1. Gains were larger and more consistent for children who received the relatively costly clinician-administered approach than for those who received a less expensive parent-administered intervention. The parent intervention was successful in helping parents to use sentence recasts, and especially so for parents of children at relatively early stages of grammatical development, Finally, children who were dismissed after a highly successful treatment Phase 1 generally exhibited no gains over the no-treatment Phase 2.
