Social work is defined as a profession that, based on human rights and social justice, supports individuals in problematic situations while also aiming to influence societal developments. Professional action requires a combination of knowledge, skills, and attitudes that reflect personal, institutional, and societal levels. This book addresses reflection theories and methods, as well as the necessity for professionals to engage with their personal contributions in interactions as a fundamental aspect of their psychosocial practice. The models developed by the authors and tested in the field of social work for case and situation reflection, as well as problem analysis, provide a practical framework for planning, evaluating, and shaping changes in the conditions of work with clients.
