Descriptions about planning sample sizes using a test of significance in 29 studies published in The Japanese Journal of Educational Psychology from July 2019 to June 2020 were reviewed and compared with those in The Japanese Journal of Psychology, Japanese Psychological Research ( JPR) and Journal of Personality and Social Psychology ( JPSP). The percentage of papers describing the statistical basis of sample sizes was the highest by approximately eight times in JPSP (93%) compared to the other three journals (7―15%). The author also examined if the effect sizes and confidence intervals, which are other crucial statistical reforms, were described in the results. Results indicated that all four journals described these more often than sample sizes and that all the papers in JPSP mentioned effect sizes and confidence intervals. On the other hand, 44% of The Japanese Journal of Educational Psychology papers mentioned neither effect sizes nor confidence intervals. Finally, the author discusses measures to promote statistical reforms in The Japanese Journal of Educational Psychology, especially in relation to sample size planning.
