Applying Rasch analysis to evaluate measurement equivalence of different administration formats of the activity limitation scale of the Cambridge Pulmonary Hypertension Outcome Review (CAMPHOR)
Twiss, J., McKenna, SP., Graham, J., Swetz, K., Sloan, J., & Gomberg-Maitland, M. (2016). Applying Rasch analysis to evaluate measurement equivalence of different administration formats of the activity limitation scale of the Cambridge Pulmonary Hypertension Outcome Review (CAMPHOR). Health and Quality of Life Outcomes, 14, 1-8. Article 57. https://doi.org/10.1186/s12955-016-0462-2
Differences between the performance of the electronic and pen and paper administrations of the CAMPHOR Activity Limitation scale were minor. The results were successful in showing how the Rasch model can be used to determine the equivalence of alternative formats of PRO measures.
