    Assessing the well-being of residents in nursing facilities : translation and validation of the German version of the Laurens Well-being Inventory for Gerontopsychiatry (LWIG-GER)
    (2021) Schott, Nadja; Johnen, Bettina; Klotzbier, Thomas J.
    Well-adapted and validated well-being (WB) instruments for the nursing home population are scarce. 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.

    Evaluation of the instrumented Timed Up and Go test as a tool to measure exercise intervention effects in nursing home residents: results from a PROCARE substudy
    (2021) Klotzbier, Thomas J.; Korbus, Heide; Johnen, Bettina; Schott, Nadja
    Background and objectives. To achieve independence in activities of daily living, a certain level of functional ability is necessary. The instrumented Timed Up and Go (iTUG) test provides guidance for appropriate interventions, for example, when considering the subphases within the TUG. Therefore, we evaluated the iTUG as a tool to measure the effects of a multicomponent exercise intervention on the iTUG subphases in nursing home residents. Methods. Fifty long-term nursing home residents (34 women, 82.7± 6.46 [65–91] years; 16 men, 78.6± 7.0 [62–90] years) performed the iTUG test before and after a 16-week intervention period (2× 45–60 min/week). According to the attendance rates, participants were divided into three groups. Results. The total iTUG duration decreased from baseline to posttest, F(2,46)= 3.50, p= 0.038, η2 p= 0.132.We observed significant correlations between the attendance rates and the total iTUG duration (r(50)= 0.328, p= 0.010). However, we did not observe significant group× time interaction effects in the subphases. The Barthel Index moderated the effect between attendance rate and the total duration of the iTUG test, ΔR2= 8.34%, F(1,44)= 4.69, p= 0.036, 95% CI [0.001, 0.027]. Conclusions.We confirmed the effectiveness of the iTUG as a tool to measure exercise intervention effects in nursing home residents, especially when participants exhibit high attendance rates. That said, mobility needs to be considered in a more differentiated way, taking into account parameters in the subphases to detect changesmore sensitively and to derive recommendations in a more individualized way.
