The Routledge Handbook of Social Work Theory provides an interdisciplinary and international introduction to social work theory. It presents an analytical review of the wide array of theoretical ideas that influence social work on a global scale. It sets the agenda for future trends within social work theory.Separated into four parts, this handbook examines important themes within the discourses on social work theory, as well as offering a critical evaluation of how theoretical ideas influence social work as a profession and in practice. It includes a diverse range of interdisciplinary topics, covering the aims and nature of social work, social work values and ethics, social work practice theories and the use of theory in different fields of practice. The contributors show how and why theory is so important to social work and analyze the impact these concepts have made on social intervention.Bringing together an international team of leading academics within the social work field and newer contributors close to practice, this handbook is essential reading for all those studying social work, as well as practitioners, policymakers and those involved in the associated fields of health and social care.
