We examined the reliability of, and relationships among, the Balloon Analogue Risk Task (BART), the Delay Discounting Task (DDT), and the Iowa Gambling Task (IGT), with a group of healthy Chinese young adults. The BART and the DDT showed moderate to high test-retest reliability across
3 test sessions conducted at 2-weekly intervals. However, the IGT showed low reliability for session 1 but high reliability for sessions 2 and 3. Between tasks, there were significant correlations only for the BART and the IGT and only for session 2 and session 3. These findings support the
view that impulsivity is a complex construct with no single personality trait underlying the disposition for impulsive behaviors.
