Due to demographic change and its implications for workforces worldwide, research on organizational practices that foster older employees’ health, motivation, and performance has increased tremendously. However, existing measures of these organizational practices tend to use unidimensional scales, apply single-item operationalizations, or focus on specific types of practices. Thus, Wöhrmann et al. (2018) developed the Later Life Workplace Index (LLWI) to provide a multidimensional model of organizational practices for older employees. Recently, a German 80-item measure for this model was developed (Wilckens et al., 2020). Despite being based on profound qualitative and quantitative research, the applicability of the measure in countries beyond Germany is yet to be determined. Hence, the measurement is currently being translated and validated in more than ten countries across the world. This presentation illustrates the standardized validation procedure using the development of the English-language version in the U.S. as an example.
