ObjectiveTo discuss the effects of nursing model based on story theory on cancer-related fatigue， anxiety， depression and quality of life of gastric cancer patients. MethodsA randomized controlled trial was conducted on 120 gastric cancer patients admitted to gastroenterology department of The First Affiliated Hospital Henan University of Science and Technology from January 2017 to January 2018. Patients were randomly classified into observation group （n=61） and control group （n=59）. All patients received routine nursing， based on this， patients in observation group received nursing model based on story theory. Interventions in both groups lasted for 3 weeks. Furthermore， all individuals were assessed using Revised Piper Fatigue Scale （RPFS）， Self-rating Anxiety Scale （SAS）， Self-rating Depression Scale （SDS） and the Short-form 36 Health Survey Scale （SF-36） at the baseline and 3 weeks after intervention. ResultsAfter intervention， there was a decrease in the each dimension score of RPFS in both groups （t_{control group}=10.305~15.639， t_{observation group}=18.821~32.589， P<0.01）， and the above scores of control group were significantly higher than those of observation group （t=10.863~16.992， P<0.01）. The scores of SAS and SDS were decreased in both groups after intervention （t_{control group}=13.964， 17.744， t_{observation group}=14.199， 9.361， P<0.01）， and the post-intervention scores of SAS and SDS were significantly higher in control group than those in observation group （t=6.505， 8.460， P<0.01）. After intervention， the score of SF-36 was elevated in both groups （t_{control group}=12.793， t_{observation group}=28.141， P<0.01）， and the post-intervention score of SF-36 was significantly lower in control group than those in observation group（t=13.757， P<0.01）. ConclusionCompared with routine nursing， nursing model based on story theory is of great significance in attenuating cancer-related fatigue， alleviating anxiety and depression， and improving quality of life of gastric cancer patients.
