Selected conceptions of defining the quality of life.

The aim of the work is to present numerous conceptions defining the quality of life. Various definitions are formulated and those presented in the work seem to characterize the concept in the most specific way. They share a lot of common features. However, there are also some differences between them mainly concerning the issue whether the quality of life is a general or rather a multi-dimensional construction and what factors determine good quality of life. It has been agreed that the quality of life is variable in time, not observable or measurable, however, as a definition, it has to be precisely established and defined.
