An 8-item version of the Barratt Impulsiveness Scale is available. The 30-item BIS is a commonly used measure of impulsiveness. The original scale has undergone a number of revisions. In 2013, Lynne Steinberg and her team evaluated an 11-item version. Based on the evidence, an 8-item version was developed. The 8-item version is knows as BIS-Brief
Each item is rated on a 4-point scale as follows.
1 = rarely/never
2 = occasionally
3 = often
4 = almost always/always
The items ask the participants about thinking, planning, and self-control.

Steinberg et al. (2013) reported evidence of construct validity based on three samples of participants in three age groups. They found similar correlations between the 8-item version and the full 30-item version. The article also includes correlations with other measures in clinical samples.
A more recent study supported the utility of the BIS-Brief in an adolescent sample. The authors noted two-dimensions of the scale (Charles, Floyd, & Barry, 2019). Link to Sage online publication.
