Relationship between impulsivity and decision making in cocaine dependence.

ABSTRACT: Impulsivity and decision making are associated on a theoretical level in that impaired planning is a component of both. However, few studies have examined the relationship between measures of decision making and impulsivity in clinical populations. The purpose of this study was to compare cocaine-dependent subjects to controls on a measure of decision making (the Iowa Gambling Task or IGT), a questionnaire measure of impulsivity (the Barratt Impulsiveness Scale or BIS-11) and a measure of behavioural inhibition (the immediate memory task or IMT), and to examine the interrelationship among these measures. Results of the study showed that cocaine-dependent subjects made more disadvantageous choices on the IGT, had higher scores on the BIS and more commission errors on the IMT. Cognitive mode
