Maternal perinatal depression and infant self-regulation: A meta-analytic review.

Infant self-regulation is shaped by early physiological systems and caregiver-infant co-regulatory interactions. Maternal perinatal (pre- and/or postnatal) depression may affect these processes and infants' development of this critical construct. However, literature addressing the association between maternal perinatal depression and infant self-regulation has been mixed. We conducted a pre-registered meta-analysis of the association between maternal perinatal depression and several self-regulation constructs (e.g., effortful control, executive function) measured during the first 2 years of life. We included 68 reports comprising 193 effect sizes and 16,722 mother-infant dyads. On average, studies included an equal number of male and female infants, and, for most (68%) studies, most participants were White. Average infant age ranged from 0 - 16 months. Three-level random effects meta-analytic models indicated a small, significant overall association, with higher levels of depression associated with lower self-regulation (r = -.10, 95% CI = -.14, -.06, p < .001). There was substantial heterogeneity in this pooled effect. Subsequent analyses indicated moderation by methodological and conceptual variables. Evidence that maternal perinatal depression is associated with lower infant self-regulation underscores the importance of supporting dyads experiencing perinatal depression. Clarifying this association highlights a critical next step of examining potential causal processes linking maternal and infant well-being.
