MISIG Task Force:

Rasch Reporting Guidelines in Rehabilitation Research (RULER)


*** Concluded mission and projects, no longer meeting ***


The purpose of the RULER Task Force is to develop guidelines for good research practices in reporting the results of clinical assessment studies that use Rasch measurement as an analytic approach.



With the exponential growth of studies applying Rasch analysis to evaluate rehabilitation outcome assessments for use in the clinic and in research, there is a need to provide guidance for consistent and transparent reporting.

The Rasch Reporting Guidelines in Rehabilitation Research (RULER) statement provides a peer-reviewed, evidence-based, and consistent guidance for reporting studies that apply Rasch Measurement (RM) Theory in a rehabilitation context so that authors, reviewers, and editors have uniform expectations on how to write and evaluate research on rehabilitation outcome assessments. The RULER statement is a framework of 6 domains reflecting primary areas of considerations in studies that report the application of RM Theory in developing and refining Rehabilitation Assessments; a checklist of items considered central to ensuring maximum transparency and reproducibility RM analysis. The RULER statement is supported by the RULER explanation and elaboration documents (2 manuscripts in development), an iteration table, and other supplemental materials available below.
