Supporting data for "Trait Behavioural Tendency Modulates Risky Decision Making Under Chronic Stress"

This is a data set collected for behavioural traits, stress and risk-taking tendency among twins adolescents.. Adolescent participants (N=70, 38 females) with 20 twin pairs included were recruited and completed the Perceived Stress Scale (PSS) to measure chronic perceived stress, the BIS/BAS scales to measure behavioural motivation tendencies particularly fun-seeking, and the Iowa Gambling Task (IGT) which assesses individuals’ risky decision making based on a history of learning about positive and negative action outcomes. The analysis indicated that BAS-fun seeking indeed significantly moderated the relationship between perceived chronic stress as indicated by PSS score, and risky decision making as measured by the IGT (β = 0.3948, t = 2.2220, p = 0.0298*). Specifically, while individuals with a high BAS fun-seeking tendency exhibited a positive relationship between chronic stress level and IGT performance score (p = 0.028*).
