Social Widerspiegelung is a central area of human life, however, it has been little researched for the theorization of social work. Otger Autrata and Bringfriede Scheu present the foundations of social Widerspiegelung and establish the essential connection between social Widerspiegelung and subjective quality of life. This makes an important contribution to the development of social work theory: The basic research on social Widerspiegelung is linked to the tasks of social work in discipline and profession.
