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.
