To our knowledge, the Laurens Well-Being Inventory for Gerontopsychiatry (LWIG) is a practical and reliable well-being assessment tool that has never been validated for German nursing home populations. Therefore, the purpose of our study was to (1) translate and crossculturally adapt the LWIG to a German context and (2) test the reliability and validity of the German LWIG in a group of older nursing home residents using the Raschmodel. Methods. This study has a cross-sectional, descriptive study design. Cross-cultural adaption of the LWIG-GER from English to German was performed according to a standardized method. The data obtained from 104 long-term nursing home residents (57 women, 47 men) aged 60–99 years (mean 79.5, standard deviation ±9.11) were analyzed for psychometric testing (exploratory and confirmatory factor analysis, item fit, McDonald’s ω, convergent validity, and known-group validity, Rasch). Results. The final LWIG-GER consists of 19 items with three subscales, including “psychologicalWB”, “socialWB”, and “physical WB”. The LWIG-GER showed good overall reliability with McDonald’s ω of 0.83; the LWIG-GER dimensions’ scores were significantly correlated with depression, functional performance, activities, fear of falling, and education. Conclusions. Our findings suggest that the German language version of the LWIG is a reliable and valid tool for measuring WB in nursing home residents. Furthermore, we propose that the LWIG-GER questionnaire can broaden and deepen our understanding of residents’ perception of quality of care and their environment.eninfo:eu-repo/semantics/openAccess150article
