Abstract
AS stepfamilies have become more common, due primarily to high divorce and remarriage rates, interest has focused on the role of the stepparent. This article explores the subsystems that comprise the stepfamily. These are the new couple system, the ex-spouse subsystem(s), and the parent-child subsystem(s)—either custodial or visiting parent. Each subsystem is analyzed in terms of its history and the threats and benefits it receives from its inclusion in the stepfamily. As subsystems continue to exist within the stepfamily structure and compete for limited resources, conflicts arise between subsystems and within subsystems between persons with membership in different subunits. Stepfamilies can become more unified through recognition of prior loyalties, negotiations to resolve conflicts, and techniques to redefine the boundaries between the subsystems.
