Parenting style impacts cognitive and behavioural outcomes of former preterm infants: A systematic review.

We sought to evaluate published evidence in aggregate regarding the impact of parenting style on the cognitive and behavioural outcomes of former preterm infants. We searched 5 databases using germane MeSH terms. Parenting style was defined as any descriptor of parenting using ≥2 dimensions on published parenting axes. We evaluated studies for quality of evidence and strength of recommendations using standardized tools and categorized summative recommendations by parenting axis and child outcome. Twenty-seven articles met our inclusion criteria. Parental responsivity is the only parenting axis strongly associated with both improved child cognition and behaviour. Parental demandingness is associated only with improved child cognition, and parental warmth and rejection are associated only with child behaviour. Parental coercion is not associated with subsequent child outcomes. Parental responsivity may be essential in optimizing neurodevelopment in former preterm infants. More targeted studies are needed to inform this relationship and identify opportunities for intervention.
