The problem
Intervention: Bilingual exposure (Spanish-English) compared to monolingual exposure (English or Spanish only) in preterm toddlers
Who it was tested with: Preterm toddlers aged 24 to 30 months (37 participants: 16 English monolingual, 16 Spanish-English bilingual, 5 Spanish monolingual; 54% female).
Experience from people who deliver programmes: stories, case studies and lessons learned. Valuable for understanding how and why, and for spotting what to test next, but not a measure of effect.
"We found substantial evidence that Spanish-English bilingual children's language skills were comparable with those of English monolingual toddlers at 24, 27, and 30 months of age." This finding directly addresses the intervention question of whether bilingual exposure affects language development in preterm toddlers, with results showing no detrimental effect.
Small sample size limits generalizability; Spanish monolingual group particularly small (n=5); no long-term follow-up beyond 30 months; cross-sectional design limits ability to determine causal mechanisms
