Participants completed the Chinese-validated Moral Distress Assessment in Professional Practice Scale, the Connor-Davidson Resilience Scale, and the Pittsburgh Sleep Quality Index. High moral distress was present in 28.6% of participants. Data were split into training (\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      = 223) and test (\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      = 95) sets.
