--- - |2 ABSTRACT Jude Cassidy and Phillip R. Shaver's third edition of the Handbook of Attachment has emerged and set a new bar for formative texts on pivotal issues related to the field of attachment. This state‐of‐the‐science reference on attachment eloquently intertwines attachment theory, research, and clinical applications, giving us innovative conceptualizations and perspectives on both implications for clinical advancement and directions for future research. This handbook moves basic research findings quickly into the realm of clinical and community applications, providing the field with new information about intervention procedures and outcomes while setting the stage for theoretical advancement. New chapters reflect the way we think about the interweaving of attachment, development, and infant mental health research and application. From the authors’ opening “Overview of Attachment” to the summary overview and evaluation of the field, “The Place of Attachment in Development” by attachment‐research pioneer L. Alan Sroufe, this third edition broadly delivers the most significant and important information that the field has on attachment. Researchers, clinicians, and professionals will benefit from this handbook as it presents with the most up‐to‐date, innovative, and thorough presentation of attachment theory. - Infant Mental Health Journal, Volume 39, Issue 5, Page 618-620, September/October 2018.
