气球模拟风险任务(BART)、延迟贴现任务(DDT)和爱荷华州赌博任务(IGT)越来越多地被用于评估冒险和冲动行为。本研究考察了这三项任务在中国健康受试者中的信度及其相互关系。BART和DDT在三次测试中显示出中等到高度的重测可靠性。然而,IGT显示前两次会议的可靠性较低,但最后两次会议的可靠性较高。在任务之间,只有BART和IGT在最近两次会议上显示出显著的相关性,而没有发现其他相关。这些发现支持这样一种观点,即冲动是一个复杂的结构,没有单一的人格特征是冲动行为倾向的基础。
The balloon analogue risk task (BART), the delay discounting task (DDT), and the Iowa gambling task (IGT) are increasingly used for the assessment of risk-taking and impulsive behaviors. This study examined the reliability of and relationships between these three tasks in healthy Chinese subjects. The BART and DDT showed moderate to high test-retest reliability across three test sessions. However, the IGT showed low reliability for the first two sessions but high reliability for the last two sessions. Between tasks, only the BART and IGT showed significant correlations at the last two sessions, while no other correlations were found. These findings support the view that impulsivity is a complex construct with no single personality trait underlying the disposition for impulsive behaviors.
