Objectives: Quality of life (QOL) is increasingly used as indicator in health research. The aim of this paper was an updated psychometric validation and a new standardization of the German version of the EUROHIS-QOL using a sample of the German general population assessed in 2021. The study focused on socio-economic characteristics and on anxiety and depressiveness as major indicators of mental health. Methods: With 8 items, the EUROHIS-QOL is an economical instrument for self-assessment. Results: Statistical tests revealed good psychometric properties. Gender- and age-group-specific norm values were calculated. The EUROHIS-QOL showed good discriminant validity for anxiety and depression symptoms. Participants without clinically relevant scores for depressiveness and anxiety reported significantly higher QOL. Multiple regression analysis showed that unemployment, younger age, not living with a partner, and an immigrant background were important predictors of lower QOL, whereas higher income, living in one's own home, and a high level of education predicted higher QOL. Conclusion: The EUROHIS-QOL was confirmed as an economical and reliable instrument for assessing QOL in the German general population.
