In a randomised controlled trial comprising 60 patients with chronic respiratory failure, the app was compared with the classic paper SRI. Thereby, it was shown that the SRI app is a practical tool that is well accepted. Missing values can be completely avoided by using the SRI app. Finally, reliability, convergent and discriminant validities were established. Accordingly, for the individual SRI subscales, Cronbach’s alpha ranged between 0.56 and 0.81 (app) and between 0.54 and 0.83 (paper), respectively. The multilingual SRI app is accessible free of charge for non-profit research purposes. ER -
