Objective: The aim of this study was to investigate the reliability and validity of a version of the Barratt Impulsiveness Scale assessed by children’s parents. Methods: The test-retest reliability, split-half reliability, and homogeneity reliability were tested. Construct validity (including internal consistency and factor structure) and criterion validity were tested. The criterion validity examined the correlation with hyperactivity and impulsive factors of the CBCL and Conners’ scales and the score differences between the control and the diagnosed groups were compared. Results: The test-retest reliability was 0.825. The split-half correlation coefficient was 0.722. The internal factors consistency α coefficient of the scale was 0.387 for attention, 0.641 for motion, 0.643 for non-plan, and the total score was 0.794. The score was related with Conners’ hyperactivity and impulsivity factors and CBCL's corresponding factors. This assessed scale included six factors. The scores of the comparison group were significantly higher than those of the control group. Conclusions: The reliability and validity of the Impulsiveness Scale assessed by parents were ideal and consistent with psychometric requirements.
Impulsiveness is defined as a predisposition toward rapid, unplanned reactions to internal or external stimuli without regard to the negative consequences of these reactions to the impulsive individuals or to others. The question of whether a person is capable of modulating their cognition and behavior to fit the demands of a given environment is integral to almost any conceivable situations. Because of this, there is widespread interest in understanding the role of impulsiveness among healthy populations in activities ranging from employment behaviors, such as error-prone to educational performance, often blurts out an answer before a question has been completed.
