Maternal and family predictors of infant psychological development in at-risk families: A multilevel longitudinal study.

ABSTRACT

The impact of different parenting-related variables on child psychological development is widely acknowledged. However, studies about the specific influence of maternal and family dimensions on child early developmental outcomes in at-risk dyads are still scarce. The aim of this longitudinal study was to investigate the short- and middle-term effects of prenatal and postnatal family and maternal features, and child attachment, on child psychological development at 3 and 24 months in at-risk families. Forty-two mothers with psychological, social and/or demographic risk conditions and their first-born infants were assessed longitudinally. Measurements of maternal personality, psychological and depressive symptoms, family socioeconomic status (SES), child-mother attachment, and infant general psychological development were collected at multiple time points, through validated questionnaires and/or mother-child observation. Maternal and family dimensions showed a significant effect on child psychological development over time. The expected detrimental role of reported maternal depressive symptoms was observed both at 3 and 24 months of child's age. Data also highlighted the negative contribution of low family SES and an unexpected positive influence of maternal personality trait of psychoticism on child psychological development at 24 months. We also found a positive association between attachment security and child developmental outcome. These findings might have relevant implications for the implementation of early prevention programs by differentiating the specific predictive role of maternal child and familial factors on child psychological development in at-risk families.
