Abstract
The Barratt Impulsiveness Scale is one of the most commonly used scales to measure impulsivity. It has demonstrated validity in several neuropsychiatric populations and correlates with objective neuropsychological measures and impulsivity-related behaviors in healthy individuals. Neuroimaging studies show that BIS scores relate to prefrontal structure and function, as well as central serotonergic function. This study reports normative data and demographic influences in a community sample (n = 700). A 15-item short form of the BIS (BIS 15) is presented that retains the 3-factor structure (nonplanning, motor impulsivity, and attention impulsivity), and maintained good reliability and validity.
