Offering fresh and provocative insights on the practice of couple and family therapy, this unique volume shows how attachment theory can inform, enhance, and guide interventions for a wide range of relationship problems and clinical issues. Chapters from leading attachment researchers and family therapists integrate the literature from both fields to provide a multifaceted perspective on the role of attachment in distressed and satisfying relationships. Illustrated with evocative clinical material, the book presents research-based therapy models for embattled couples, families struggling with parent-child conflict and adolescent problems, and adoptive and foster families. Also discussed are ways to support stronger mother-infant attachment; attachment-oriented interventions for couples facing specific clinical problems, including depression, PTSD, and chronic pain; applications for same-sex couples; and much more.
