Question Matrix

One of the first products of the first meeting of the Washington Group was the development of a matrix that cross-classifies the purpose that a general disability measure is supposed to address (i.e., the use that the data will be put to) with a typology of question characteristics which address concepts such as domain, severity, etiology and duration. The cells of the conceptual version of the matrix describe the information on each of the question characteristics that is needed to satisfy each of the specific purposes. In addition, an empirical version of the matrix is being developed that evaluates the characteristics of the general measures currently in use according to the dimensions of the matrix. These two matrices, which detail what we need to measure to fulfill purposes as well as what we have measured with existing general indicators, are intended to help us identify the gaps that exist in disability measurement. They will also help to direct our future work in developing internationally comparable general measures of disability. Work on both the conceptual and empirical matrix is currently underway by a team with members from Italy, the United Nations, and the United States. Anyone interested in joining in this effort should contact Jennifer Madans, National Center for Health Statistics,

Results of Testing General Disability Measures

Several countries have undertaken research in the area of general disability measures and presented plans or preliminary results at the first meeting. Some developing countries expressed interest in adopting models being proposed by other countries. The second group meeting will provide an opportunity for countries with results from recent censuses or sample based surveys to present their analyses and recommendations to the group. Countries who currently have plans to test such measures would also have an opportunity to share them with other members. Plans for further testing (for instance, in developing countries ) could be developed as a result of this exchange of information.
