Over recent decades, attachment theory has come to be seen as fundamental to understanding not only childhood development and how people survive and grow, but also the capacity of partners, parents and carers to offer safe and consistent care, particularly under difficult conditions. Attachment-based Practice with Children, Adolescents and Families integrates attachment theory with other key concepts to explore the ways in which we understand and respond to troubled young people. Drawing on psychiatry, psychotherapy, social work, clinical psychology, systemic therapy and multi-modal assessment and intervention, and combining theory, practical guidance and illustrated case studies, the authors present an attachment-based, integrative, biopsychosocial approach to working with individuals and families that is designed to promote improved outcomes for all involved.
