This and previous studies of disruption identify a variety of characteristics associated with adoption stability or disruption. These characteristics can be categorized as occurring in the three areas we previously specified as key to the adjustment to adoption: the child, the parents and household, and family interaction. Agency services and support that respond to these characteristics are a fourth part of this model. This chapter begins by reviewing the important variables in each of these areas to determine their relative importance within each area in contributing to adoption disruption or stability. The second part of this chapter considers the way these factors combine to influence adoption outcomes.
