Are individual differences in loss aversion related to ADHD symptomatology?

Abstract

Abstract Loss aversion, or the greater sensitivity to losses than equivalent gains, has been shown to vary across individuals, but has yet to be thoroughly examined in relation to Attention-Deficit/Hyperactivity Disorder (ADHD) symptomatology. Examining factors related to decision-making in ADHD has important implications for interventions as well as understanding engagement in risky behavior. Undergraduates (N = 98; 73% women) completed questionnaires measuring ADHD symptomatology, loss aversion, and gambling preference as well as the Balloon Analog Risk Task. Individuals with high ADHD symptomatology (n = 50) were less loss averse than those low in symptomatology, even after controlling for individual differences in risk taking and gambling preference. Inattention symptoms were not related to loss aversion after controlling for hyperactivity/impulsivity, risk taking, and gambling preference. Greater hyperactivity/impulsivity was related to less loss aversion, even after covariates were controlled. It is unclear if group differences were the result of reduced sensitivity to losses, increased attraction to gains, or both. Future research should examine if reduced loss aversion in those with high ADHD symptomatology replicates using other decision-making paradigms and whether or not loss aversion mediates the relationship between ADHD and risk-taking behavior.
