To represent the state-of-the-art in understanding the relation between personality and risk-taking, we selected a decision task with characteristics that parallel risk-taking in the real world and two personality traits commonly believed to influence risk-taking. A meta-analysis is presented based on 23 studies of the Balloon Analogue Risk Task from which correlations with sensation seeking and impulsivity could be obtained. Results showed that effect size for the relation of sensation seeking with risk-taking was in the small-moderate range, while the effect size for impulsivity was in the null-small range. Moderator analyses revealed only a significantly larger sensation seeking effect size for the older adolescents and young adults compared to other ages. The type of personality scale was also a significant moderator of both personality risk-relations, thereby showing that an unsystematic choice of a specific assessment scale may result in a larger or smaller effect-size.
