Abstract
Background: The quality of parenting is associated with a wide range of child and adult outcomes, and there is evidence to suggest that some aspects of parenting show patterns of intergenerational transmission. This study aimed to determine whether such intergenerational transmission occurs in mothers and fathers in a UK birth cohort. Methods: The study sample consisted of 146 mothers and 146 fathers who were recruited from maternity wards in England and followed up for 24 months ['Generation 2' (G2)]. Perceptions of their own parenting [by 'Generation1' (G1)] were assessed from G2 parents at 12 months using the Parental Bonding Instrument (PBI). G2 parents were filmed interacting with their 'Generation 3' (G3) children at 24 months. Results: We found that G1 mothers' 'affection' was associated with positive parenting behaviour in the G2 fathers ('positive responsiveness' beta = 0.19, P = 0.04 and 'cognitive stimulation' beta = 0.26, P < 0.01). G1 mothers' 'control' was associated with negative parenting behaviour in G2 mothers (decreased 'engagement' beta = -0.19, P = 0.04), and negative parenting behaviour in G2 fathers (increased 'control' beta = 0.18, P = 0.05). None of the G1 fathers' parenting variables were significantly associated with G2 parenting. Conclusions: There is evidence of intergenerational transmission of parenting behaviour in this highly educated UK cohort, with reported parenting of grandmothers associated with observed parenting in both mothers and fathers. No association was seen with reported parenting of grandfathers. This raises the possibility that parenting interventions may have benefits that are realised across generations.
