Persistent maternal mental health and child's behavioural, academic, and educational outcomes: evidence from national...

Maternal mental health is an important determinant of child development, yet most evidence relies on short exposure windows or single-wave measures. Less is known about how long-run maternal mental health relates to child outcomes when child development data are observed intermittently.

Using nationally representative longitudinal household panel data, we examined associations between maternal mental health and child behavioural outcomes, academic performance, and expectations of future university participation. Child outcomes were observed in three survey waves, while maternal mental health was measured repeatedly over a longer period. Maternal mental health was operationalized as long-run averages of general mental health and psychological distress. Ordinary least squares models were estimated with adjustment for child, maternal, and household characteristics, and standard errors were clustered at the mother level.

Higher maternal psychological distress was associated with poorer academic performance and less favourable behavioural and educational outcomes. Associations involving general maternal mental health were attenuated after full adjustment.

Persistent maternal psychological distress is associated with poorer child academic outcomes. Although causal inference is not possible, the findings highlight maternal mental wellbeing as an important correlate of child development.
