Understanding the Barratt Impulsivity Scale
The Barratt Impulsiveness Scale (BIS) stands as a cornerstone in measuring impulsivity, a trait that significantly impacts decision-making and behavior. Developed by Ernest Barratt, this self-report questionnaire has become widely used in psychology and psychiatry to assess impulsive tendencies. The BIS-11, the most current version, consists of 30 items that evaluate three main dimensions of impulsivity: attentional, motor, and non-planning.
Mental health professionals and researchers rely on the BIS to gain insights into various psychological conditions and behavioral patterns. The scale's ability to quantify impulsivity has proven valuable in understanding disorders such as attention deficit hyperactivity disorder (ADHD), substance abuse, and certain personality disorders. Its application extends beyond clinical settings, finding use in fields like criminology and neuroscience.
The BIS has undergone several revisions since its inception, with each iteration refining its ability to capture the multifaceted nature of impulsivity. This ongoing development reflects the evolving understanding of impulsive behavior in psychology and psychiatry. The scale's enduring relevance in mental health assessment underscores the importance of accurately measuring impulsivity in both research and clinical practice.
Overview of the Barratt Impulsivity Scale
The Barratt Impulsivity Scale (BIS) is a widely used psychological assessment tool for measuring impulsiveness. It evaluates different aspects of impulsive behavior through a self-report questionnaire.
Historical Background
Ernest Barratt developed the Barratt Impulsiveness Scale in the 1950s. The scale has undergone several revisions since its inception.
The current version, BIS-11, was introduced in 1995. It reflects decades of research and refinement in impulsivity measurement.
Barratt's work aimed to create a comprehensive tool for assessing impulsive personality traits and behaviors. The scale has become a standard in psychological research and clinical practice.
BIS-11 as a Self-Report Measure
The BIS-11 consists of 30 items rated on a 4-point Likert scale. Participants respond to statements about their thoughts and behaviors.
The scale measures three main domains of impulsivity:
Attentional impulsivity
Motor impulsivity
Non-planning impulsivity
These domains can be further divided into six dimensions:
Attention
Motor
Self-control
Cognitive complexity
Perseverance
Cognitive instability
Scores range from 30 to 120, with higher scores indicating greater impulsivity. The BIS-11 provides valuable insights into an individual's impulsive tendencies across various aspects of personality and behavior.
Psychometric Properties of BIS-11
The Barratt Impulsiveness Scale-11 (BIS-11) has undergone extensive psychometric evaluation. Studies have examined its validity, reliability, internal consistency, and factor structure to assess its effectiveness as a measure of impulsivity.
Validity and Reliability
The BIS-11 demonstrates good validity and reliability across diverse populations. Convergent validity has been established through correlations with other impulsivity measures. Studies show moderate to strong correlations between BIS-11 scores and behavioral tasks assessing impulsivity.
Test-retest reliability of the BIS-11 is generally acceptable, with coefficients ranging from 0.71 to 0.83 over periods of 1 month to 1 year. This indicates the scale's stability in measuring impulsivity traits over time.
Criterion validity is supported by the scale's ability to differentiate between clinical and non-clinical groups. Individuals with impulse control disorders tend to score higher on the BIS-11 compared to healthy controls.
Internal Consistency
The BIS-11 exhibits good internal consistency. Cronbach's alpha coefficients typically range from 0.79 to 0.83 for the total score, indicating that items within the scale measure the same underlying construct of impulsivity.
Subscale reliability varies:
Attentional impulsiveness: α = 0.74 - 0.77
Motor impulsiveness: α = 0.59 - 0.70
Non-planning impulsiveness: α = 0.72 - 0.76
These values suggest adequate to good internal consistency for most subscales, though the motor impulsiveness subscale shows lower reliability in some studies.
Factor Structure
The factor structure of the BIS-11 has been a subject of debate. The original three-factor model proposed by Patton et al. (1995) includes:
Attentional impulsiveness
Motor impulsiveness
Non-planning impulsiveness
Confirmatory factor analyses have yielded mixed results. Some studies support the three-factor structure, while others suggest alternative models. A two-factor solution combining attentional and motor impulsiveness has been proposed by some researchers.
Cultural differences may influence the factor structure. Studies in non-Western populations have found varying factor solutions, highlighting the need for cross-cultural validation of the BIS-11.
Construction and Format
The Barratt Impulsiveness Scale-11 (BIS-11) is a widely used self-report measure of impulsivity. It consists of 30 items scored on a 4-point Likert scale, yielding a total score and several subscale scores.
Questionnaire Items
The BIS-11 contains 30 statements describing common impulsive behaviors and preferences. Respondents rate how often each statement applies to them using a 4-point scale: 1 (Rarely/Never), 2 (Occasionally), 3 (Often), and 4 (Almost Always/Always).
Sample items include:
"I plan tasks carefully"
"I do things without thinking"
"I am restless at lectures or talks"
The questionnaire covers different aspects of impulsivity, including attention, motor, and non-planning impulsiveness.
Scoring the BIS-11
Scoring the BIS-11 involves summing the ratings for all 30 items to obtain a total score. Total scores range from 30 to 120, with higher scores indicating greater impulsivity.
The scale also provides subscale scores:
Attentional Impulsiveness
Motor Impulsiveness
Non-planning Impulsiveness
Some items are reverse-scored before calculating the total. Researchers and clinicians can use the total score or subscale scores depending on their specific needs.
Factors of Impulsivity
The Barratt Impulsiveness Scale identifies three main factors of impulsivity: cognitive, motor, and non-planning. These factors provide insight into different aspects of impulsive behavior and decision-making tendencies.
Cognitive Impulsivity
Cognitive impulsivity relates to quick decision-making and difficulty maintaining focus. It involves a tendency to make rapid cognitive decisions without fully considering consequences.
People high in cognitive impulsivity often:
Have racing thoughts
Struggle to concentrate
Make decisions quickly without deliberation
Experience difficulty with complex thinking tasks
This factor encompasses attention and cognitive instability. Those with high cognitive impulsivity may act without thinking or have trouble focusing on one task for extended periods.
Motor Impulsivity
Motor impulsivity involves acting without thinking and a lack of perseverance. It manifests as a tendency to act on impulse without considering potential outcomes.
Key characteristics include:
Acting on the spur of the moment
Difficulty sitting still
Restlessness and fidgeting
Interrupting others
People high in motor impulsivity often engage in behaviors before fully processing the situation. They may struggle with tasks requiring sustained effort over time.
Non-Planning Impulsivity
Non-planning impulsivity refers to a lack of forethought and future orientation. It involves difficulty planning ahead and considering long-term consequences of actions.
Common traits include:
Living in the moment without concern for the future
Lack of careful planning for tasks or events
Difficulty saving money or budgeting
Preference for immediate gratification over long-term rewards
Individuals high in non-planning impulsivity may struggle with tasks requiring advance preparation or delayed gratification. They often focus on present circumstances rather than future outcomes.
Application and Relevance
The Barratt Impulsiveness Scale finds extensive use across various domains. Its applications span clinical settings, research studies, educational contexts, and community samples. The scale provides valuable insights into impulsivity-related behaviors and traits.

BIS Variants and Adaptations
The Barratt Impulsiveness Scale has evolved through various adaptations and translations to suit different populations and research needs. These modifications aim to enhance the scale's applicability across cultures and contexts.
International Adaptations
The BIS has been translated and validated in numerous languages and cultures. The Italian version of the BIS-11 has shown good psychometric properties, maintaining the original scale's three-factor structure. Researchers have also adapted the scale for use in Spanish, Chinese, and French-speaking populations.
These international versions undergo rigorous translation and back-translation processes to ensure cultural relevance and conceptual equivalence. Validation studies often compare the adapted versions to the original BIS to confirm reliability and validity across different cultural contexts.
BIS-Brief Versions
Shorter versions of the BIS have been developed to reduce participant burden and increase efficiency in research settings. The BIS-Brief is a condensed 8-item version that retains strong correlations with the full BIS-11.
Another abbreviated form, the BIS-15, consists of 15 items selected from the original 30. This version maintains the three-factor structure (attentional, motor, and non-planning impulsiveness) while offering a more concise assessment tool.
The BIS-10 is yet another shortened adaptation, featuring 10 items. It provides a quick measure of impulsivity while still capturing the essential aspects of the construct.
Scale Performance and Enhancements
The Barratt Impulsiveness Scale has undergone extensive evaluation and refinement over the years. Researchers have employed factor analysis techniques to examine its structure and improve its psychometric properties.

Factor analysis studies have played a crucial role in assessing the BIS-11's construct validity. Exploratory factor analysis and principal components analysis have been used to identify underlying dimensions of impulsivity. These studies have revealed a complex structure, with some researchers finding support for a three-factor model and others identifying up to six factors.
Second-order factors have also been examined, providing insights into broader impulsivity domains. The most commonly reported factors include attentional impulsiveness, motor impulsiveness, and non-planning impulsiveness.
Some studies have challenged the original factor structure proposed by Patton et al. (1995), suggesting the need for further investigation and potential revisions.
Adjustments and Refinements
Based on factor analysis results and other psychometric evaluations, researchers have proposed adjustments to the BIS-11. These refinements aim to enhance the scale's reliability and validity.
One notable refinement is the development of the 21-item Barratt Impulsiveness Scale Revised (BIS-R-21). This shortened version maintains strong psychometric properties while reducing respondent burden.
Other modifications include:
Rewording of certain items to improve clarity
Removal of reverse-scored items to reduce confusion
Addition of new items to better capture specific impulsivity facets
Researchers continue to evaluate and refine the BIS to ensure its utility in diverse populations and research contexts.
Impulsivity in Clinical Populations
Impulsivity plays a significant role in various mental health conditions and addictive behaviors. It manifests differently across disorders, influencing symptom severity and treatment outcomes.
Mental Disorders and Impulsivity
Borderline Personality Disorder (BPD) is characterized by high levels of impulsivity. Individuals with BPD often engage in risky behaviors and have difficulty controlling their emotions. This impulsivity can lead to self-harm, substance abuse, and unstable relationships.
Bipolar Disorder also features impulsive behaviors, particularly during manic episodes. Patients may make rash decisions, overspend, or engage in risky sexual activities. In depression, impulsivity can manifest as suicidal thoughts or attempts.
Attention-Deficit/Hyperactivity Disorder (ADHD) is strongly associated with impulsivity. Children and adults with ADHD struggle with waiting their turn, interrupting others, and making hasty decisions without considering consequences.
Addiction and Risk-Taking Behaviors
Substance abuse disorders are closely linked to impulsivity. Individuals with high impulsivity scores on the Barratt Impulsiveness Scale are more likely to develop addictions. This trait can lead to difficulty resisting cravings and maintaining sobriety.
Gambling disorder is another condition where impulsivity plays a central role. Problem gamblers often exhibit poor impulse control, leading to continued betting despite negative consequences.
Risk-taking behaviors, such as dangerous driving or unsafe sexual practices, are more common in individuals with high impulsivity. These behaviors can have serious health and legal implications.
Antisocial Personality Disorder is characterized by a pattern of disregard for others' rights and impulsive, often criminal, behavior. This impulsivity can manifest as aggression, recklessness, and a failure to plan ahead.
Implications for Future Research
The Barratt Impulsivity Scale continues to be a valuable tool in impulsivity research. Future studies can enhance its utility and expand our understanding of impulsive behaviors.
Improving Assessment Methods
Researchers should focus on refining the psychometric properties of the Barratt Impulsivity Scale. This includes conducting more extensive validation studies across diverse populations and cultural contexts.
Factor analysis techniques could be employed to further clarify the scale's underlying structure. This may lead to improved subscales that better capture different facets of impulsivity.
Incorporating advanced statistical methods, such as item response theory, could enhance the scale's precision in measuring impulsivity across various levels of severity.
Understanding Impulsivity Dynamics
Future research should explore the relationships between impulsivity and other psychological constructs. This includes examining links between impulsivity and cognitive complexity, urgency, and self-control.
Longitudinal studies could shed light on how impulsivity changes over time and in response to life events or interventions. Such research may reveal patterns in impulsivity trajectories across different age groups.
Neuroimaging studies combined with Barratt Impulsivity Scale assessments could provide insights into the neural correlates of impulsive behaviors. This interdisciplinary approach may uncover new targets for interventions.
Investigating the role of impulsivity in psychological distress and negative urgency could lead to improved treatment strategies for various mental health conditions.
