Background/Description
The Barratt Impulsiveness Scale (BIS) is a psychological assessment tool developed by psychologist Dr. Ernest Barratt in 1959. The BIS is a self-report questionnaire that measures impulsivity, which is defined as a tendency to act on a whim, without considering the consequences of one’s actions.
The original version of the BIS consisted of 30 statements that assessed different aspects of impulsivity, such as attentional impulsiveness, motor impulsiveness, and non-planning impulsiveness. Respondents rated the statements on a 4-point scale, from “rarely/never” to “almost always/always.”
Since its development, the BIS has undergone several revisions to improve its validity and reliability. It has been used in a variety of settings, including clinical and research settings, to assess impulsivity in individuals with various psychological and behavioral disorders, such as attention deficit hyperactivity disorder (ADHD), substance abuse, and personality disorders.
The BIS has been shown to be a reliable and valid measure of impulsivity, although it is important to note that it is just one tool in the assessment of this complex construct. Other measures and assessments, as well as clinical judgment, should also be considered when assessing impulsivity.
Administration, Scoring and Interpretation
The Barratt Impulsiveness Scale (BIS) is a self-report questionnaire that consists of 30 statements that assess different aspects of impulsivity. Respondents rate the statements on a 4-point scale, from “rarely/never” to “almost always/always.”
The BIS can be administered in paper-and-pencil format or electronically, depending on the preferences of the researcher or clinician. It typically takes about 15 to 20 minutes to complete.
Scoring of the BIS is relatively straightforward. Each item is scored on a scale of 1 to 4, with higher scores indicating greater levels of impulsivity. The scores for all 30 items are summed to create a total impulsiveness score, with possible scores ranging from 30 to 120.
In addition to the total score, the BIS can also be scored on three subscales that assess different aspects of impulsivity: attentional impulsiveness, motor impulsiveness, and non-planning impulsiveness. These subscales can provide additional information about the individual’s specific areas of impulsivity.
It is important to note that the BIS is just one tool in the assessment of impulsivity, and should be used in conjunction with other measures and assessments, as well as clinical judgment, to develop a comprehensive understanding of the individual’s impulsivity.
Reliability and Validity
The Barratt Impulsiveness Scale (BIS) has been found to be a reliable and valid measure of impulsivity.
Reliability refers to the consistency of scores over time or across different administrations of the scale. The BIS has been found to have good internal consistency, meaning that the items on the scale are measuring the same construct. Test-retest reliability has also been found to be good, indicating that the BIS produces consistent scores over time.

Frequently Asked Questions
What is the Barratt Impulsiveness Scale?
The Barratt Impulsiveness Scale (BIS) is a widely used self-report questionnaire designed to assess impulsivity. It consists of a series of statements that respondents rate on a scale, and it measures three main dimensions of impulsivity: attentional, motor, and non-planning impulsiveness.
What are the different versions of the BIS?
There are several versions of the BIS, including the BIS-11, BIS-15, BIS/BAS scales, BIS-10, and BIS-Plus. Each version has different numbers of items and assesses impulsivity across different domains.
How is the BIS administered and scored?
The BIS is administered as a self-report questionnaire, where respondents rate each item on a scale. The scores are then tallied to give an overall score for each of the three dimensions of impulsivity, as well as a total score for overall impulsivity.
What is the reliability and validity of the BIS?
The BIS has been found to be a reliable and valid measure of impulsivity, with good internal consistency and test-retest reliability. It also has good construct validity and has been shown to correlate with other measures of impulsivity.
What populations has the BIS been used in?
The BIS has been used in a variety of populations, including individuals with ADHD, substance abuse, and personality disorders, as well as healthy controls.
What is the purpose of using the BIS in research or clinical settings?
The BIS can be used to assess impulsivity as a personality trait, as well as a potential risk factor for a range of problematic behaviors, such as substance abuse, gambling, and risky sexual behavior. It can also be used to inform clinical decision-making and treatment planning for individuals with impulsivity-related disorders.
