Key Components of Parenting Education Interventions for Preterm Infant–Parent Dyads Admitted to the NICU: A Systematic Review

NICU educational interventions positively influence parental knowledge, confidence, and parent-infant interaction; however, substantial variation and limited conceptual grounding hinder their comparability and scalability. The evidence base remains dominated by high-income settings, which limits its global applicability. Future research must prioritise theory-informed design, transparent reporting, and context-sensitive adaptation, particularly in under-resourced health systems, to support equitable and effective parental education for families of preterm infants worldwide.
