Abstract: | Performance-based neuropsychological tests are often used to assess planning and impulse control, but the extent to which these measures reflect trait impulsiveness or specific dimensions of trait impulsiveness is not clear. This study used the Barratt Impulsiveness Scale-11 (BIS-11; Patton, J. H., Stanford, M. S., & Barratt, E. S. (1995). Factor structure of the Barratt Impulsiveness Scale. Journal of Clinical Psychology, 51, 768–774.]) to examine the relationship between various dimensions of trait impulsiveness and performance on several executive function tests in healthy young adults. Total BIS-11 scores correlated with performance on measures of planning and impulse control. Higher non-planning impulsiveness scores, which indicate poorer self-control and lower cognitive complexity, correlated most strongly with performance on a maze test that measures planning and impulse control (r = .58). These results provide support for the convergent validity of pencil-and-paper maze-based measures of planning and impulse control. |
