To introduce the Gastrointestinal Symptoms Index Revised (GCSI-R) scale and verify its reliability and validity in mild acute pancreatitis patients.

Following the Brislin principle of translation, 2 nursing graduate students who passed CET-6 translated English version GCSI-R scale and 2 oversea graduated nursing experts in the nursing related field who were highly proficient in both Chinese and English did the backtranslation and made the cultural adjustments to the scale through expert consultation and pre-surveys. By convenience sampling, 99 patients with mild acute pancreatitis admitted in Pancrea Center in a ClassⅢ Grade A hospital in Jiangsu Province from January to May of 2018 were selected and tested the reliability and validity of the scale. Finally, 83 valid scales were included to analyze the reliability and validity of the revised version among the patients with mild acute pancreatitis.

The Chinese version of scale consisted of 8 items with 3 dimensions (nausea/vomiting, early satiety, bloating) . The Chinese version of the GCSI-R scale had a Cronbach's α coefficient of 0.765, and the dimensions of Cronbach's α coefficients were 0.739, 0.739, and 0.725 respectively, and the test-retest reliability was 0.805. Evaluated by the committee of experts, the content validity of various items in the Chinese version of GCSI-R (S-CVI/Ave) on average was 0.90, and their content validity index (I-CVI) ranged 0.80 to 1.00. Exploratory factor analysis extracted a total of 3 common factors, which explained 72.17% of the total variance, and the factor load of each item on its common factor was >0.4.

The Chinese version of GCSI-R scale has good reliability and validity and can be used as a simple tool for self-assessment on gastrointestinal function in patients with acute pancreatitis during the early period of hospitalization.
