The objective was to present an overview of methods to examine the validity of the minimum data set of the interRAI Acute Care (interRAI AC). Because of the multidimensional character of this comprehensive geriatric assessment tool, clinimetric testing of the interRAI AC can be more complex than that of one-dimensional instruments. Thus to facilitate testing of the interRAI AC, we translated this complexity into a structured methodological framework that outlines procedures to assess various lines of evidence. Our framework combined traditional clinimetric techniques and the standards of psychological testing. For each line of evidence, examples of hypotheses and research questions were summarized. Future clinimetric testing can use these guidelines as a basis to obtain and provide a wide and diverse body of evidence.
