Abstract：Objective:To translate the Surgery Task Load Index(SURG-TLX)into Chinese and validate its reliability and validity,while employing network analysis to examine the structural relationships between SURG-TLX and the NASA Task Load Index(NASA-TLX).Methods:The Brislin translation model was adopted for forward and back translation of SURG-TLX,followed by cross-cultural adaptation through expert panel discussions and a preliminary survey.From October 2022 to May 2023,639 surgical healthcare professionals from five tertiary grade A hospitals in Changzhou city were surveyed to assess the scale's reliability and validity.Results:The Chinese version of SURG-TLX consisted of six items.The scale-level content validity index(S-CVI)was 0.920,while item-level content validity indices(I-CVI)ranged from 0.800 to 1.000.The Cronbach's α coefficient was 0.886.The test-retest reliability was 0.801.Scores from the Chinese SURG-TLX showed a positive correlation with NASA-TLX scores(P<0.001).Network analysis revealed strong associations between"mental demand"and"task complexity"in SURG-TLX,whereas"mental demand"and"physical demand"were closely linked in NASA-TLX.Conclusions:The Chinese version of SURG-TLX demonstrates good reliability and validity,making it an effective tool for assessing surgical task load,particularly in measuring task complexity,intraoperative distractions/interruptions,and situational stress among surgical healthcare professionals.
