Book excerpt: The definitive therapist manual for Integrative Behavioral Couple Therapy (IBCT)—one of the most empirically supported approaches to couple therapy. Andrew Christensen, codeveloper (along with the late Neil Jacobson) of Integrative Behavioral Couple Therapy, and Brian Doss provide an essential manual for their evidence-based practice. The authors offer guidance on formulation, assessment, and feedback of couples’ distress from an IBCT perspective. They also detail techniques to achieve acceptance and deliberate change. In this updated edition of the work, readers learn about innovations to the IBCT approach in the 20+ years since the publication of the original edition—including refinements of core therapeutic techniques. Additionally, this edition provides new guidance on working with diverse couples, complex clinical issues, and integrating technology into a course of treatment.
