The relationship between psychosocial factors and developmental outcome for very low and extremely low birthweight infants: a review

Abstract

Over the last quarter century, the improved survival rate of very low birthweight infants has sharpened questions about their residual disabilities. Longitudinal studies have devoted attention to the cognitive and neurodevelopmental outcome of these infants, but much less is known about their long-term social and emotional development. Psychiatrists consulting to neonatal intensive care units and assessing these infants in their families, will be assisted by a better understanding of the developmental and psychological outcomes of such infants. This paper reviews the state of knowledge in both of these areas. It argues the paramount importance of psychosocial factors to the infants' developmental outcome, and the importance of longitudinal research in further clarifying the predictive value of these factors. In a subsequent paper, we consider the efficacy of interventions with this group.
