OBJECTIVE: Healthcare workers involved in, and negatively affected by, patient safety incidents are referred to as second victims. The Second Victim Experience and Support Tool-Revised (SVEST-R) can reveal the second victim's degree of negative experiences and the desirability of the support options. However, a Japanese version of the SVEST-R (J-SVESTR) has not yet been developed. This study aimed to translate and adapt the SVEST-R into Japanese and validate its psychometric properties. METHODS: We performed forward and back translations of the SVEST-R and evaluated its clarity and content validity. Subsequently, we administered a cross-sectional questionnaire survey to evaluate the construct validity, internal consistency, and retest reliability of the J-SVESTR. RESULTS: The J-SVESTR was finalized with clarity and content validity supported by a pilot test and an expert panel. In total, 224 healthcare workers responded to the J-SVESTR survey. The 9 factors and 35 items model indicated an acceptable fit (χ 2 / df = 1.811, root mean square error of approximation = 0.060, comparative fit index = 0.871, Tucker-Lewis index = 0.854, standardized root mean squared residual = 0.077). Cronbach's α values ranged from 0.68 to 0.85. The intraclass correlation coefficients ranged from 0.63 to 0.87. CONCLUSIONS: The J-SVESTR retained 9 factors and 35 items, with no item changes from the original. The psychometric properties of the J-SVESTR are acceptable. The J-SVESTR can help investigate the actual situation and desired support options for second victims in Japan.
