Attention deficit and hyperactivity disorder (ADHD) is associated with increased engagement in risk-taking behaviors. The present study aimed to further our knowledge regarding the extent and the reasons for the association between ADHD symptoms and risk-taking, using a theory-driven behavioral economy theory. The Domain Specific Risk-Taking scale was used, on which 244 adults rated the likelihood of engagement in a range of risky behaviors, across five real life domains, as well as the magnitude of perceived benefit and risk they ascribed to these behaviors. Level of ADHD symptoms was positively correlated with engagement in risky behaviors and benefit perception, but not with risk perception. Mediation analysis confirmed that benefit perception, but not risk perception, mediated the association between ADHD symptoms and engagement in risk-taking behaviors (Fig. 1). These findings emphasize the role of benefit perception in facilitating risk-taking by people with ADHD symptoms.
