Reward magnitude-specific delay discounting differentiates mania versus depression risk.

ABSTRACT: Mania/hypomania, the pathognomonic feature of bipolar disorder (BD), is characterized by elevated impulsivity, often assessed via delay discounting-the preference for smaller, immediate versus larger, delayed rewards. It remains unclear whether delay discounting differentiates BD from non-BD individuals or serves as an objective behavioral marker of mania/hypomania versus depression risk. Bipolar disorder (n = 40) and non-BD (n = 187) individuals were recruited, with the latter encompassing a range of mania/hypomania and depression risk and stratified into mania/hypomania and depression risk tertiles. Kruskal-Wallis and Dunn's tests evaluated delay discounting rates (k values), assessed via the 27-Item Monetary Choice Questionnaire, across both risk groups compared to the BD group. Signifi
