Using survey data from 292 mothers married to members of the U.S. military, the authors examined relations among military deployment factors, quality of maternal care, and child attachment behavior with the mother. The results revealed that maternal perceptions of quality of care, mothers' depressive symptoms, and fathers' involvement when not deployed were significantly associated with children's attachment behavior. In addition, fathers' combat exposure was negatively associated with children's attachment behavior. Mothers' quality of care partially mediated the association between fathers' involvement and children's attachment behavior as well as the association between mothers' depressive symptoms and children's attachment behavior. A notable finding of this study was that deployment-related factors were both directly and indirectly related to children's attachment.
