This welcome resource provides concrete examples of how to apply multiple family systems theories and treatment planning to common stepfamily issues. A single stepfamily case study is examined through the lenses of the Adlerian, transgenerational, prescriptive play therapy, structural, cognitive behavior, solution-focused, and narrative models to provide an understanding of the benefits of each approach and how to determine the best fit for a stepfamily's presenting issues. In addition, each chapter examines ethical concerns specific to counseling stepfamilies, issues of diversity, and current research on stepfamily assessment and therapeutic outcomes.
