Abstract
The 11th version of the Barratt Impulsiveness Scale (BIS-11) is a short self-report questionnaire developed for impulsivity assessment. The aim of the present study was to evaluate the psychometric properties of the Lithuanian version of BIS-11. The research comprised a sample of 298 Lithuanian adults. The analyses included the test of construct validity, as well as confirmatory and exploratory factor analysis, internal consistency, test-retest reliability, and predictive validity. The exploratory factor analysis showed a three-factor structure and confirmatory factor analyses suggested that its structure was suitable. Additionally, the analyses showed: a good construct validity, good internal consistency (α = .803) and good test-retest reliability. It was also found that the results of BIS-11 were predictive of behaviors related to breaking the law, smoking, and alcohol consumption. To sum up, the present study suggests that the Lithuanian version of the BIS-11 has good psychometric properties and is a valid measure of impulsiveness in Lithuanian adults.
