{Abstract}: BACKGROUND: Preterm children have a higher risk for linguistic delays than full-term infants but are rarely provided with language intervention at an early age. Knowledge on early language interventions targeted to preterm children is scarce, and efficacy of the interventions is rarely reported.
OBJECTIVE: This systematic review aims to identify interventions for preterm children aged 0-3 years with at least one language outcome. Efficacy of the interventions and quality of the study reports were evaluated.
METHODS: The article search was carried out in six databases: EBSCOhost, Scopus, ERIC, LLBA, Ovid, and Web of Science. Effect sizes (Hedges' g) were calculated for language outcomes. Quality of the study reports was assessed using the levels of evidence system by the American Speech-Language-Hearing Association.
RESULTS: The 28 studies identified were divided into three groups: interventions at Neonatal Intensive Care Unit, interventions during the first year, and interventions during the second and/or third years. Most of the interventions focused on supporting child-care and general development. Of the interventions, 61 % were efficacious in supporting language development of preterm children. The most promising results regarding efficacy were interventions conducted during the second and/or third years (80 %). Quality of the reports varied from high/good (89 %) to low (11 %).
CONCLUSIONS: The 28 existing studies provide limited evidence of the efficacy of very early interventions promoting language development of preterm children. However, especially the results for interventions conducted during the second and/or third years show promise. More studies, particularly language-focused interventions with longer follow-ups, are needed.
