Objective. The Barratt Impulsivity Scale (BIS-11) was discussed in the paper.
Review. Overimpulsiveness occurring in many mental disorders may significantly affect both the course of the disease and therapeutic procedures. Impulsiveness is an important problem in clinical practice. In the assessment of impulsiveness constituting a crucial element of psychopathological analysis various scales are used to measure different aspects of this variable and its intensity. The BIS-11 is often used in the research on the relationship between impulsiveness and biological factors, and in studies on drug efficacy and effectiveness of psycho-therapeutic methods in the treatment of individuals with impulsiveness disturbances. The history of the scale development was briefly outlined, and the Polish adaptation of the BIS-11 is enclosed in the paper.
Conclusions. The BIS-11 is an instrument useful not only in clinical practice, but also for research purposes.
