Résumé
Several studies have observed a relationship between (subclinical levels of) attention-deficit hyperactivity disorder (ADHD) and entrepreneurship. Recently, Yu et al. (Entrep Theory Pract

) observed a positive association between hyperactivity and entrepreneurial orientation (EO). The present study seeks to replicate these findings in an entirely different culture, that of Japan. Moreover, because of the low internal consistency of the hyperactivity measure across studies, we study the individual contributions of the hyperactivity items. Using a sample of 255 Japanese business owners, we conducted OLS regressions and PLS-structural equation modelling. The results of our study on the ADHD-EO relationship in Japan are partly in line with previous findings: the positive link between hyperactivity and EO is again confirmed. In contrast with the results of previous studies, we find a positive link between overall ADHD symptoms and EO using both methods and a positive link between attention-deficit and EO using one of the methods (PLS-SEM). Cultural differences may explain these different findings. When the two hyperactivity items are separated, they appear to have different associations with EO. One item, measuring mental hyperactivity, is strongly positively associated with EO, whereas the other item, measuring physical hyperactivity, is not associated with EO. This result is a new and interesting finding that is replicated in the current study using the French dataset of Wismans et al. (Appl Psychol 69:1093–1112
