Book excerpt: "Nine central issues relevant to attachment theory and research constitute this volume: Defining attachment and attachment security, Measuring the security of attachment, The nature and functioning of internal working models, Stability and change in attachment security, Influence of early attachment, Culture and attachment, Separation and loss, Attachment-based interventions, and Attachment, systems, and services. This is a time of widening interest in attachment theory, and this book exists alongside others that provide perspective on the field as a whole. The authors of these chapters have synthesized their views into fresh perspectives that, juxtaposed with others addressing the same questions, offer novel and useful insights into the current status of attachment theory and research, and perspective on its future"--
