With reference to the questionnaire adopted within the Italian project"Ulisse" to assess health condition of elderly people, we investigate twoimportant issues: discriminant power and actual number of dimensions measuredby the items composing the questionnaire. The adopted statistical approach isbased on the joint use of the latent class model and a multidimensional itemresponse theory model based on the 2PL parametrization. The latter allows us toaccount for the different discriminant power of these items. The analysis isbased on the data collected on a sample of 1699 elderly people hosted in 37nursing homes in Italy. This analysis shows that the selected items indeedmeasure a different number of dimensions of the health status and that theyconsiderably differ in terms of discriminant power (effectiveness in measuringthe actual health status). Implications for the assessment of the performanceof nursing homes from a policy-maker prospective are discussed.
