A meta‐analysis on the effectiveness of intervention in children with primary speech and language delays/disorders: Focusing on China and the United States

Abstract

The purpose of this meta-analysis was to investigate the immediate and long-term effects of intervention for children with primary speech and language delays/disorders and to explore whether some characteristics of interventions, specifics of the study and research participants moderate the magnitude of the effectiveness of interventions. Using the random effect model, we pooled the effect size and conducted a publication bias evaluation, a moderating effect analysis in CMA 2.0. Results of a random effects model analysis demonstrated a moderate immediate effect (g = 0.70), whereas the long-term efficacy was small (g = 0.23). Additionally, type of measure, language of intervention, parental involvement, intervention content and study quality, as well as the duration of intervention, significantly moderated the effect size of intervention effectiveness.

Exploring The Effects of English as a Foreign Language on First Language Development of Young Children: The Case of Greece

“…Furthermore, Faraone et al (2021) provide a comprehensive consensus on the nature and treatment of ADHD, elucidating the intricacies involved in managing conditions that frequently intersect with Communication Disorders. Zhang et al (2021) emphasize the effectiveness of interventions for children with primary speech and language delays/disorders, indicating a global imperative for informed and efficacious strategies. Therefore, a dedication to sustained research will not only deepen theoretical understanding of Communication Disorders but will also improve outcomes for individuals affected by these challenges, enhancing their quality of life and communicative abilities.…”

“…This is seriously emphasized in a meta-analysis study by Zhang, Xu, and Joshi. [32] Randomized controlled studies are needed to examine the impact of psychological intervention over time. [32] Future studies should further explore underlying variables that moderate the impact of therapies.…”

“…[32] Future studies should further explore underlying variables that moderate the impact of therapies. [32] Therefore, approaches and techniques involved in child-focused interventions become imperative. It is demeaning that despite the importance of childhood development, meta-analysis studies reported the worrisome limited studies on children's speech and self-esteem.…”
