Conclusions
NASH
NASH-CHECK is a novel PRO measure developed specifically for use with patients with NASH. The scale structure identified in this study is consistent with the conceptual model originally developed from the literature and qualitative research conducted with patients with NASH. Scale scores derived from the measure are reliable, valid, and able to detect change. The results of this psychometric evaluation suggest NASH-CHECK is a valuable tool to capture patients’ experiences with the symptoms of NASH and its impact on HRQOL in clinical trials and in routine practice. NASH-CHECK is free for use and can be accessed via the authorized distributor at
