Children of highly anxious mothers are at risk for developmental difficulties including anxiety disorders, and "anxious maternal behavior" and disturbed mother-infant interactions have been implicated in the transmission of risk. In this article, we describe interactions between mothers who are highly anxious and their young infant, based on the few directly relevant observation studies that are available. For more detail, we draw on a broader literature including studies of depressed mothers and developmental theory. Our goal is to describe how the interactions between anxious mothers and infants look to an outside observer and how they may feel to mothers and infants. We also discuss possible bases for their disturbed interactive behavior, the impact that the disturbances can have on both mothers and infants, buffers and risk factors, and routes to short-term intervention. Finally, we suggest directions for future research on maternal anxiety and anxious maternal behavior and the significance of such research for clinicians and researchers.
