The main aim of the present study was to derive norms or reference values from the general Norwegian population for the Norwegian version of the Quality of Life Scale (QOLS-N). In addition, associations between socio-demographic and health variables on the level of quality of life were examined. The sample consisted of 1893 subjects from a total of 4000 randomly selected Norwegian citizens representative of the entire Norwegian population, aged 19-81. The subjects received a mailed questionnaire containing the QOLS-N. Results show that the mean quality of life score was 84.1 (SD 12.5). Women reported a higher quality of life than men. People with higher levels of education reported a higher quality of life. Those who were married or cohabitating reported the highest quality of life and those who were unemployed reported a lower quality of life than those who worked. In addition, people reporting long-term diseases or health problems scored significantly lower on quality of life. These results could serve as reference values for the level of quality of life, as measured by the QOLS-N in the Norwegian population.
