Publication of a new article regarding the CAMPHOR

Health and Quality of Life Outcomes has published the article “Applying Rasch analysis to evaluate measurement equivalence of different administration formats of the Activity Limitation scale of the Cambridge Pulmonary Hypertension Outcome Review (CAMPHOR)” (10.1186/s12955-016-0462-2).

Electronic formats of patient-reported outcome measures are generally employed in clinical research studies. It is important to establish the equivalence of different administration formats. The study investigated whether there are any differences in the data generated from paper and pen administration and an electronic format of the CAMPHOR Activity Limitation scale. The research introduces a clear methodological framework for using the Rasch model in this process, which should prove invaluable for future equivalence testing of alternative formats of PRO measures.
