Localization and validation of Abdominal Surgery Impact Scale-Revised

Abstract

Objective To introduce Abdominal Surgery Impact Scale-Revised (ASIS-R) and to verify its reliability and validity in acute pancreatitis patients. Methods ASIS-R were translated into Chinese by 2 nursing postgraduates who passed College English Test-6 (CET-6) in accordance with Brislin's translation principle. The Chinese version of ASIS-R were then translated back into English by two nursing specialists who graduated abroad and were proficient both in English and Chinese. The scale was culturally adjusted through pre-survey. Totally 182 acute pancreatitis patients attending the Pancreas Center of a Class Ⅲ Grade A hospital in Jiangsu Province from October 2017 to April 2018 were selected by convenient sampling, and a total of 173 valid questionnaires were included to analyze the scale's reliability and validity in acute pancreatitis patients. Results The Chinese version of ASIS-R had 14 items in total, including limitation of motion, function impairment, visceral function, sleep and psychological function. Its Cronbach's α coefficient was 0.719, and that of different dimensions was 0.966, 0.964, 0.972, 0.976 and 0.968, respectively. The retest reliability was 0.660. Evaluated by the committee of experts, the content validity of various items in the Chinese version of ASIS-R (S-CVI/Ave) averaged 0.95, and their content validity index (I-CVI) ranged 0.80-1.00. Totally 5 common factors were extracted by exploratory factor analysis, which could account for 94.93% of the total variance. The factor loading of various items on their common factors were>0.4. Conclusions The Chinese version of ASIS-R has sound reliability and validity, which may serve as a tool for acute pancreatitis patients to evaluate the short-term quality of life in hospital by themselves.
