The effects of socioenvironmental conditions that impede or undermine development (risk factors) and the conditions that promote or enhance development (opportunity factors) were examined in a study of 192 mothers and their one-year-old children. The outcomes constituting the focus of investigation were maternal psychological well-being (positive and negative affect) and child cognitive development. Results showed that the presence of multiple risk factors in the absence of opportunity factors had negative consequences on both the maternal and child outcomes, and that the presence of multiple opportunity factors in the absence of risk factors had positive consequences on both outcomes Implications for improving early childhood intervention practices are described.
