Understanding how theory informs social work practice is an area that students can often find challenging.  This book will help students understand how theory impacts and informs social work practice across a range of contexts and with different service user groups. It starts off by briefly setting the context, introducing students to the importance of social work theory and its development over the years, before moving on to look at different types of theory across 17 tightly structured chapters. These cover a range of psychological theories, sociological theories, ethics and moral philosophies, political theories and ideologies, and organisational theories.
