Catastrophizing, when an individual overestimates the probability of a severe negative outcome, is related to various aspects of mental ill-health. Here, we further characterize catastrophizing by investigating the extent to which self-reported catastrophizing is associated with risk-taking, using an online behavioural task and computational modelling.
We performed two online studies: a pilot study (n = 69) and a main study (n = 263). In the pilot study, participants performed the Balloon Analogue Risk Task (BART), alongside two other tasks (reported in the Supplement), and completed mental health questionnaires. Based on the findings from the pilot, we explored risk-taking in more detail in the main study using two versions of the Balloon Analogue Risk task (BART), with either a high or low cost for bursting the balloon.
In the main study, there was a significant negative relationship between self-report catastrophizing scores and risk-taking in the low (but not high) cost version of the BART. Computational modelling of the BART task revealed no relationship between any parameter and Catastrophizing scores in either version of the task.
We show that increased self-reported catastrophizing may be associated with reduced behavioural measures of risk-taking, but were unable to identify a computational correlate of this effect.
灾难化思维是指个体高估严重负面结果的可能性，它与心理健康的各个方面都有关联。在此，我们通过使用在线行为任务和计算建模来研究自我报告的灾难化思维与冒险行为之间的关联程度，从而进一步刻画灾难化思维的特征。
我们进行了两项在线研究：一项预试验（n = 69）和一项主要研究（n = 263）。在预试验中，参与者完成了气球模拟风险任务（BART）以及其他两项任务（补充材料中有报告），并填写了心理健康问卷。基于预试验的结果，我们在主要研究中使用了两个版本的气球模拟风险任务（BART），即气球破裂成本高或低的版本，更详细地探究了冒险行为。
在主要研究中，自我报告的灾难化思维得分与低成本（而非高成本）版本的BART中的冒险行为之间存在显著的负相关。对BART任务的计算建模显示，在该任务的任何一个版本中，任何参数与灾难化思维得分之间均无关联。
我们表明，自我报告的灾难化思维增加可能与冒险行为的行为测量指标降低有关，但未能确定这种效应的计算关联因素。
