[Measuring the quality of life of mentally-ill patients: is it possible to compare with quality of life of healthy population?].

Investigations of the quality of life of mentally-ill patients can be conducted with illness-specific assessment tools, e.g. Lehmans Quality of Life Interview guide. The present article reviews WHOQOL, which is the questionnaire method of the WHO, developed on the basis of a multidimensional quality of life concept. WHOQOL has been translated into Danish and validated by both patient groups and the Danish population. Data from the population investigations can be used as a reference when interpreting data from groups of patients. The WHOQOL-BREF questionnaire has been used in an investigation of schizophrenic patients.
