Intergenerational transmission of parenting: findings from a UK longitudinal study.

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' ß = 0.19, P = 0.04 and 'cognitive stimulation' ß = 0.26, P < 0.01). G1 mothers' 'control' was associated with negative parenting behaviour in G2 mothers (decreased 'engagement' ß = -0.19, P = 0.04), and negative parenting behaviour in G2 fathers (increased 'control' ß = 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.

Salivary cortisol response to infant distress in pregnant women with depressive symptoms.

The Hypothalamic-Pituitary-Adrenal (HPA) axis has been proposed as a potential underlying biological mechanism linking prenatal depression with adverse offspring outcomes. However, it is unknown whether the reactivity of this system to stress is altered in pregnant women experiencing depression. The objective of this study was to investigate whether salivary cortisol response to a distressed infant film is enhanced in pregnant women with symptoms of depression compared with non-depressed controls. Salivary cortisol and subjective mood responses to the film were measured in 53 primiparous women, between 11 and 18 weeks gestation. Both groups showed similar increases in state anxiety in response to the film, but there was a significantly increased cortisol response in women experiencing symptoms of depression. Depression during pregnancy is associated with increased reactivity of the HPA axis. This is consistent with altered HPA axis functioning being a key mechanism by which prenatal mood disturbance can impact upon fetal development.
