The stepfamily is one of the fastest growing family forms, and family-
centered practitioners can expect to have such families in their case
loads. Differences between stepfamilies and biologically based familie
s need to be understood by practitioners, because work with these fami
lies requires different approaches. The author notes these differences
as well as the usefulness and problematic aspects of the systemic and
behavioral approaches traditionally wed by family-centered practition
ers in work with stepfamilies. An integrated model for working with st
epfamilies, developed by the author, is presented. This model integrat
es postmodern approaches into eco-systemic and behavioral work.
