Attachment Theory for Social Work Practice [PDF ebook] 

The quality of early social relationships has a deep bearing on our psychological and social development; adversity in childhood can lead to adult relationships that may be difficult and distressing. This book addresses the needs of social workers in understanding and assessing the nature and origins of such disturbed social relationships. Taking a comprehensive and wide-ranging look at the theories emerging in and around attachment theory, it provides a sophisticated but accessible base from which social workers can make sensitive assessments and develop humane practices.
