Aim To examine the factorial validity of the M aslach B urnout I nventory– S tudent S urvey, using a sample of 2061 J apanese university students majoring in the medical and natural sciences (67.9% male, 31.8% female; M age = 19.6 years, standard deviation = 1.5). The back‐translated scale used unreversed items to assess inefficacy. Methods The inventory's descriptive properties and C ronbach's alphas were calculated using SPSS software. The present authors compared fit indices of the null, one factor, and default three factor models via confirmatory factor analysis with maximum‐likelihood estimation using AMOS software, version 21.0. Results Intercorrelations between exhaustion, cynicism, and inefficacy were relatively higher than in prior studies. C ronbach's alphas were 0.76, 0.85, and 0.78, respectively. Although fit indices of the hypothesized three factor model did not meet the respective criteria, the model demonstrated better fit than did the null and one factor models. The present authors added four paths between error variables within items, but the modified model did not show satisfactory fit. Subsequent analysis revealed that a bi‐factor model fit the data better than did the hypothesized or modified three factor models. Conclusion The J apanese version of the M aslach B urnout I nventory– S tudent S urvey needs minor changes to improve the fit of its three factor model, but the scale as a whole can be used to adequately assess overall academic burnout in Japanese university students. Although the scale was back‐translated, two items measuring exhaustion whose expressions overlapped should be modified, and all items measuring inefficacy should be reversed in order to statistically clarify the factorial difference between the scale's three factors.
