[Quality of life as a planning and evaluation criterion in psychiatric management].

In sociology and psychology, quality of life and subjective well-being have been being relevant constructs and subject of empirical research for several decades. Results of this research are reviewed, and findings of the more pragmatic specific studies on quality of life in the mentally ill are summarised. Although subjective quality of life may be influenced by various factors, it stands as an own important criterion. Finally, some open questions for empirical research, for theoretical studies and for public discussion are mentioned. These questions should be addressed before a decision can be made as to which extent quality of life is a useful criterion for the planning and evaluation of mental health care.
