The Speech Perception Questionnaire (SPQ) is a subjective and objective measure of public speaking performance. The purpose of present study was to develop the Japanese version of the SPQ. First, the permission was obtained from the author of the original SPQ and it was translated into Japanese. Then, the content validity of a back-translated version of the Japanese SPQ was confirmed and approved by the author of the original SPQ. Three hundred and forty-three undergraduate students were screened by using the Short Fear of Negative Evaluation scale (SFNE). Of these, two groups of participants, with high (HS group; n = 10) and low social anxiety (LS group; n = 10) were selected based on the scores of SFNE. The participants engaged in 3-minute speech task. ANOVA were conducted on the Z-scores of the SPQ based on their self-ratings and observers' ratings. The results indicated that the HS group rated their own performance to be worse than the LS group (p < .05). Moreover, there was a significantly greater discrepancy between their self-ratings and observers' ratings in the SPQ (p < .05). Furthermore, Cronbach's α indicated the high internal consistency of the SPQ. These results suggest that the Japanese version of SPQ has high internal consistency and construct validity.
