Postpartum depression can negatively impact children
Area of Science:
- Child Psychology
- Maternal Mental Health
- Developmental Psychology
Background:
- Postpartum depression's short-term effects on maternal-infant interaction are known.
- Long-term developmental impacts on children require further investigation.
Purpose of the Study:
- To quantify the long-term effects of maternal postpartum depression on child development.
- To analyze cognitive and emotional development in children over one year old.
Main Methods:
- A meta-analysis was conducted.
- Nine studies meeting specific sample criteria were included in the analysis.
Main Results:
- Postpartum depression showed a small but statistically significant effect on children's development.
- Effect sizes (r) ranged from .18 to .22; (d) ranged from .36 to .45.
Conclusions:
- Maternal postpartum depression has measurable long-term consequences for child cognitive and emotional development.
- Further research is needed to explore these implications.
Abstract:
The adverse, short-term effects of postpartum depression on maternal-infant interaction have been repeatedly documented. Are there long-term sequelae for children whose mothers had experienced postpartum depression? The purpose of this meta-analysis was to determine the magnitude of the effect of postpartum depression on the cognitive and emotional development of children older than the age of 1 year. Nine studies which met the sample criteria were included in this meta-analysis. Results indicated that postpartum depression had a small but significant effect on children's cognitive and emotional development. The r indicator for effect size ranged from .18 to .22 whereas the d indicator ranged from .36 to .45. Implications for future research are addressed.
