Beneficial effects of grandparental involvement vary by lineage in the UK

Evolutionary theory predicts that based on sex-specific reproductive interests maternal grandparents increase child well-being more than paternal grandparents. In this article we study the association between grandparental involvement and children’s emotional and behavioural problems measured by the Strength and Difficulties Questionnaire (SDQ). We use the Involved Grandparenting and Child Well-Being 2007 survey, which is a representative data of 11–16-year-old adolescents from England and Wales. We test two hypotheses: (H1) There is an association between maternal grandparents’ involvement and fewer emotional and behavioral problems in children, but there is no association between paternal grandparents’ involvement and fewer emotional and behavioral problems in children; (H2) The involvement of maternal grandparents decreases the child’s emotional and behavioral problems more often than paternal grandparents’ involvement. The results support both hypotheses and are in line with the evolutionary prediction.

► Grandparental involvement correlates with fewer emotional and behavioral problems.
► Maternal grandparents decrease the child’s emotional and behavioral problems.
► Paternal grandparents do not decrease the child’s emotional and behavioral problems.
