Insights
Early infant social-emotional development is crucial. This review identifies key perinatal factors, like caregiving responsiveness and maternal mental health, that predict attachment security and behavioral regulation by mid-infancy.
Area of Science:
- Developmental Psychology
- Perinatal Health
- Social-Emotional Development
Background:
- Infant social-emotional development significantly impacts lifelong outcomes.
- Existing screening tools often miss early infancy, creating a developmental assessment gap.
- No systematic review has synthesized evidence on perinatal factors for early social-emotional markers.
Purpose of the Study:
- To examine modifiable risk and protective factors during the perinatal window (pregnancy to 10 months postpartum).
- To identify predictors for two key early social-emotional markers: attachment security and behavioral regulation in mid-infancy (12-18 months).
Main Methods:
- Systematic review of meta-analytic and longitudinal studies.
- Searched six electronic databases (ERIC, PsycINFO, Medline Complete, Informit, Embase, Scopus).
- Analyzed developmental relationships between perinatal exposures and infant social-emotional status at 12-18 months.
Main Results:
- Identified 12 modifiable indicators across infant, caregiving, and contextual domains predicting social-emotional outcomes.
- Key predictors included caregiving responsiveness, maternal mental health, couple relationship quality, and socioeconomic status (SES).
- Perinatal factors closest to the infant showed the strongest associations; infant-specific factors (excluding medical risks) were less consistently predictive.
Conclusions:
- Caregiving, maternal, and contextual factors in the perinatal period are vital for infant social-emotional development.
- Findings support developing early screening tools for primary care and population health.
- Understanding these modifiable factors can inform interventions to promote healthy infant social-emotional trajectories.
Abstract:
The importance of infant social-emotional development for outcomes across the lifecourse has been amply demonstrated. Despite this, most screening measures of social-emotional development are designed for children 18 months of age and over, with a clear gap in earlier infancy. No systematic review has yet harvested the evidence for candidate indicators in the perinatal window. This paper examines modifiable risk and protective factors for two seminal early markers of social-emotional development: attachment security and behavioral regulation mid-infancy. We searched meta-analytic and longitudinal studies of developmental relationships between modifiable exposures in the perinatal window (pregnancy to 10 months postpartum) and attachment and behavioral regulation status measured between 12 and 18 months. Six electronic databases were used: ERIC, PsycINFO, Medline Complete, Informit, Embase, and Scopus. Twelve meta-analytic reviews and 38 original studies found replicated evidence for 12 indicators across infant, caregiving, and contextual domains predictive of infant behavioral regulation and attachment status between 12 and 18 months. Key among these were caregiving responsiveness, maternal mental health, couple relationship, and SES as a contextual factor. Perinatal factors most proximal to the infant had the strongest associations with social-emotional status. Beyond very low birthweight and medical risk, evidence for infant-specific factors was weaker. Risk and protective relationships were related but not always inverse. Findings from this review have the potential to inform the development of reliable tools for early screening of infant social-emotional development for application in primary care and population health contexts.
