Abstract:
Objective For the development of the electronic patient-reported outcome measures(ePRO)for stroke,the scale′s equivalence,i.e,differential item functioning(DIF)was assessed,aiming to compare whether paper-and mobile-based collection methods affect the participants′responses.Methods The patient information was collected using the developed App,and the DIF was detected using the mean and covariance structure(MACS)model to analyse whether the scale maintained a good measurement equivalence after changing to mobile-based from paper-based.Results Items PHD7,PHD8,PHD14,PSD3,PSD9,SOD1,and SOD6 exhibited uniform DIF(P1＜α1),PHD9,PHD10,PHD11,PHD12,SOD5,and THD1 exhibited non-uniform DIF(P2＜α2),and SOD7 and THD2 exhibited both uniform and non-uniform DIF.The DIF between the different measurement modalities existed for the above 15 items;however,it was within the acceptable limit.Conclusion The mPRO patient follow-up system developed in this study by assessing the DIF between the scale′s different data collection methods confirmed that mobile-based data collection did not affect the participants′response,and the measurement method shift did not affect the scale measurement equivalence.The system yielded accurate and reliable measurements that can be used in clinical practice and optimized in its application course.
