Objective To translate the Second Victim Experience and Support Tool （SVEST) into simplified Chinese and to test the reliability and validity. Methods After obtaining authorization from the creator, we translated the SVEST into simplified Chinese and conducted back-translation, then selected 258 clinical nurses using convenience sampling method to complete the questionnaire. Results The Cronbach′s α coefficient for the total scale was 0.892 and for the dimensions ranged from 0.444 to 0.916. The content validity index （CVI） was 0.950. Confirmatory factor analysis (CFA) indicated that the nine-factor model provided the best fit (χ2/df=2.299, comparative fit index=0.879, Tucker-Lewis index=0.856, and root mean square error of approximation=0.071). Conclusion The simplified Chinese version of the SVEST is reliable and valid to assess the second victim experience and support of clinical nurses in China.
