Standards Task Force


This task force was formed to review existing resources and recommend terms to standardize measurement terminology as it applies to rehabilitation research and practice.

Other groups have defined measurement standards, such as the COSMIN (COnsensus-based Standards for the selection of health Measurement Instruments), and the American Educational Research Association, American Psychological Association, and the National Council on Measurement in Education, which jointly publish the Standard for Educational and Psychological Testing. However, these two resources define terms like validity in different ways, and neither has been reviewed for suitability for rehabilitation research and practice.

For instance, in defining validity, COSMIN uses a traditional definition of “the degree to which an HR-PRO instrument measures the construct(s) it purports to measure,” whereas the Standard for Educational and Psychological Testing uses the definition of “the degree to which accumulated evidence and theory support a specific interpretation of test scores for a given use of a test.

The Standards Task Force will compile and review a set of measurement terminology resources from a rehabilitation perspective, and make recommendations for a standard set of terms and definitions. Specific task force activities will be determined by the task force and could include a review of measurement term usage in rehabilitation journals.
