Maternal perinatal depression and child executive function: A systematic review and meta-analysis

Area of Science:

• Developmental Psychology
• Neuroscience
• Public Health

Background:

• Maternal depression during the perinatal period is a known risk factor for adverse child developmental outcomes.
• The precise mechanisms linking maternal depression to child outcomes remain unclear.
• Child executive function, crucial for social, emotional, and educational success, is a potential mediating pathway.

Purpose of the Study:

• To systematically review and meta-analyze the evidence on the association between maternal perinatal depression and child executive function.
• To evaluate the quality of existing research in this area.
• To provide a quantitative estimate of the relationship.

Main Methods:

• Comprehensive literature search across major databases (Medline, Embase, PubMed, PsycInfo, SCOPUS) up to August 2020.
• Inclusion of 27 studies measuring maternal depressive symptoms and child executive function.
• Meta-analysis of 16 studies with available raw data.

Main Results:

• Systematic review revealed limitations in the assessment of maternal depression and child executive function, and inconsistent control for confounders.
• Meta-analysis found a small, statistically significant association between maternal perinatal depression and child executive function (effect size r = 0.07, Cohen's d = 0.14).

Conclusions:

• The findings support the hypothesis that maternal perinatal depression impacts offspring executive function.
• Results should be interpreted cautiously due to the variable quality of included studies.
• Future research requires rigorous measurement of depression and executive function, considering chronicity and developmental context.
