The book provides an overview of the fundamental assumptions and key findings of attachment research. Case studies from everyday life in care homes illustrate the value of attachment theory knowledge. Attachment theory, which examines the impact of early relationship experiences on a child's further personality development, is currently one of the most fruitful research areas in developmental psychology. However, its findings have hardly been acknowledged by the theory of residential care. This book is an attempt to bridge that gap. It offers an overview of the basic assumptions and findings of attachment research. Additionally, it presents the results of an initial empirical study on the attachment organization of adolescents in residential care. Vivid case studies from daily life in care homes emphasize the value of this knowledge.
