RT Journal Article T1 ADHD Symptoms, Entrepreneurial Orientation (EO), and Firm Performance A1 Yu, Wei A1 Wiklund, Johan A1 Pérez-Luño, Ana K1 ADHD K1 Entrepreneurial orientation K1 Venture performance K1 Personality K1 Mental health AB Recently, scholars have started to investigate the relationship between ADHD (Attention Deficit Hyperactivity Disorder) symptoms and entrepreneurship, finding that ADHD symp-toms positively impact entrepreneurial intention and action. However, the performance impli-cations of ADHD symptoms are still unknown. Using two samples of entrepreneurs from the United States and Spain, we find evidence that impulsive and hyperactive symptoms of ADHD are largely conducive to firm performance through entrepreneurial orientation (EO) while in-attention symptoms are not. This suggests that the performance advantages of entrepreneurs ADHD symptoms can be derived from greater focus on innovation, proactiveness, and risk- taking. We discuss the implications of our findings for the entrepreneurship literature.
