Aim This study developed the J apanese version of the B erkeley E xpressivity Q uestionnaire ( BEQ ), a self‐report measure of three emotional expressivity facets, and provided evidence of its reliability and validity. Methods Five hundred and four students answered an online survey. To determine test–retest reliability, 241 of the participants completed the J apanese version of the BEQ again approximately 1 month after initial surveying was completed. Results C ronbach's alpha coefficients were 0.83 for the BEQ full scale, and 0.61–0.77 for subscales. Test–retest correlations were 0.61 for the full scale, and 0.57–0.61 for subscales. Construct validity was demonstrated by correlations between BEQ scores and scores on measures of emotional expressivity, self‐monitoring, self‐esteem, depression, “Big Five” (neuroticism, extraversion, openness, agreeableness, and conscientiousness) personality traits, and emotional control. Conclusion The Japanese version of the BEQ has adequate internal consistency, reliability, and construct validity. Test–retest reliability was lower than that of the original scale. This study was the first in J apan to develop a self‐rating questionnaire assessing multiple facets of emotional expressivity.
