The Effectiveness of Parent-Implemented Language Interventions: A Meta-Analysis

The results indicate that parent-implemented language interventions have a significant, positive impact on receptive and expressive language skills of children with and without intellectual disabilities. Effect sizes (g) for child measures ranged from -0.15 to 0.82 depending on the outcome measure and comparison group.

The results of this review indicate that parent-implemented language interventions are an effective approach to early language intervention for young children with language impairments. Critical features of parent-implemented interventions are discussed in terms of implications for practice and future research.
