The relationship between impulsiveness subtraits,trait anxiety,and visual N100 augmenting/reducing: A topographic analysis

The relationship between impulsiveness subtraits assessed by the Barratt Impulsiveness Scale (BIS-10), the trait anxiety subscale of the State-Trait Personality Inventory (STPI), and the topographic distribution of visual N100 augmenting/reducing (AR) was examined. Topographic event-related potential (ERP) data were collected from an array of 14 electrodes covering the left side of the head while subjects counted the total number of light flashes presented at two different but equiprobable intensities. Principal components analysis of the ERP data yielded a factor accounting for 13.9% of the total variance around the grand mean waveform that corresponded to the N100 wave clearly visible in the raw waveforms. For each subject by scalp locus combination, an AR score was computed by subtracting the factor score associated with the bright flashes from the factor score associated with the dim flashes. The correlations between AR scores and scores on the BIS-10 cognitive impulsiveness subscale were significant (P < 0.01) at all scalp loci with the exception of the extreme frontal and occipital poles. Correlations with the BIS-10 motor impulsiveness subscale had a similar scalp distribution. Correlations with the BIS-10 non-planning impulsiveness subscale were significant over the frontal third of the scalp, including the frontal pole. Trait anxiety was not significantly related at the 0.01 level to AR scores. Theoretical implications of these findings are discussed.     

Quick to Act,Quick to Forget: The Link Between Impulsiveness and Prospective Memory

Several traits of impulsiveness (e.g. lack of planning and perseverance, difficulty focusing attention) seem intimately connected to the skills required for successful prospective memory performance. This is the first study to examine whether the various inter‐correlated dimensions of impulsiveness are related to problems with prospective memory. Undergraduate students (N = 184) completed the Barratt Impulsiveness Scale 11, the Prospective Memory Questionnaire, the Prospective and Retrospective Memory Questionnaire, and two objective prospective memory tests. Results revealed consistent correlations between the various dimensions of impulsiveness (attentional, motor, non‐planning) and self‐reported problems with prospective memory. Subsequent regression analyses indicated that attentional impulsiveness is a unique predictor of self‐reported problems with internally cued prospective memory, and non‐planning impulsiveness is a unique predictor of self‐reported problems with episodic and overall prospective memory. Similarly, findings from the objective prospective tests showed that non‐planning impulsiveness was related to worse performance on the two prospective memory tests. Whereas non‐planning impulsiveness was also related to using fewer prospective memory‐aiding strategies, mediation analyses showed that use of these strategies does not account for any of the detected relationships. Because the findings suggest that a failure to plan does not underlie the detected effects, other potential explanations for the relationships are discussed.

Psychometric properties of the German version of the Barratt Impulsiveness Scale, Version 11 (BIS-11) for adolescents

Impulsiveness is increasingly gaining attention as a potential risk factor for various mental disorders. Until now, there have been German instruments that allowed for assessing adolescents' self-reported impulsiveness multi-dimensionally. The present study examined the German version of the Barratt Impulsiveness Scale-11 (BIS-11) for adolescents. The instrument was completed by 659 adolescents ages 10 to 20 years; 98 were retested after 6 months. Items showed adequate psychometric properties. An exploratory factor analysis identified three factors that showed slightdifferences from the initial questionnaire proposed by Barratt. The factors showed low to moderate intercorrelations, satisfactory internal consistency (dependent on factor), and were stable over time. Convergent validity was ascertained, and the item pool showed sufficient power to discriminate adolescents with symptoms of attention deficit hyperactivity disorder and those with loss of eating control from healthy adolescents. Findings suggest that the German BIS-11 is appropriate for reliable investigation of impulsiveness in adolescents. Future research should examine sensitivity as a screening tool, as well as sensitivity to change.     

Adaptation et validation d’une version brève en langue française du questionnaire d’impulsivité de Barratt (BIS-15)

IntroductionThe Barratt Impulsiveness Scale is one of the most frequently used questionnaires to assess impulsivity. Many versions of the questionnaire were developed during the 50 years that followed its creation.ObjectivesThis article reports validation data for a French-language version of Spinella's (2007) BIS-15 questionnaire, a short version of Barratt's original scale (BIS-11; Patton, Standford, & Barratt, 1995).MethodReliability, principal component analyses and confirmatory factor analyses have been conducted with two university student samples (study 1, n = 366; study 2, n = 322).ResultsThe results of this study revealed a number of redundant items, which lead us to consider a unidimensional model with correlated measurement errors. Cronbach's alpha reliability was acceptable for study 1 (0.71), and satisfactory for study 2 (0.81). Test-retest reliability was also satisfactory (0.84). Elements of external validity (correlations with anxiety, neurosis, and extraversion) are reported.ConclusionsConsiderations regarding the type of response scales and assessment methods used in questionnaires are discussed in the conclusion.     

Impulsive behaviour in interpersonal encounters: Associations with quarrelsomeness and agreeableness

Associations between impulsivity and interpersonal behaviours have rarely been examined, even though impulsivity may disrupt the flow of social interactions. For example, it is unknown to what extent the commonly used Barratt Impulsiveness Scale (BIS‐11) predicts impulsive behaviour in social situations, and how behaving impulsively during interpersonal encounters might influence levels of quarrelsomeness and agreeableness. In this study, 48 healthy working individuals completed the BIS‐11 and recorded their behaviour in social situations using event‐contingent recording. Record forms included items representing quarrelsome, agreeable, and impulsive behaviours. BIS‐11 motor impulsiveness scores predicted impulsive behaviour in social situations. Impulsive behaviour was associated, in different interactions, with both agreeableness and quarrelsomeness. Behaving impulsively in specific interactions was negatively associated with agreeableness in participants with higher BIS‐11 motor impulsiveness and positively associated with agreeableness in participants with lower BIS‐11 motor impulsiveness. Impulsive quarrelsome behaviour may cause interpersonal problems. Impulsive agreeable behaviour may have positive effects in individuals with low trait impulsivity. The idea that there are between‐person differences in the effects of state impulsivity on the flow of social interaction deserves further study.     

I need my smartphone: A hierarchical model of personality and cell-phone addiction

Using a comprehensive personality model, this study is the first to examine the relationship between a full range of personality traits and cell phone addiction. 346 college students completed an online survey that asked respondents to complete measures of the Big-Five personality traits and measures of materialism and need for arousal, Barratt’s (1959) impulsiveness scale, and a four-item measure of cell phone addiction. Data were analyzed using structural equation modeling. Couched in Mowen’s (2000) 3M Hierarchical Model of Personality, the elemental traits of emotional instability and materialism were positively associated while introversion was negatively associated with cell phone addiction. The central trait of attention impulsiveness exhibited a direct and positive association with cell phone addiction. A significant negative relationship between conscientiousness and all three dimensions of Barratt’s impulsiveness scale (central trait) was found. Several additional relationships between the elemental traits of Mowen’s personality hierarchy and the three dimensions of impulsiveness (central trait) also were uncovered. Study implications and future research directions are discussed.     

Further validation of the Penny Beliefs Scale - Weapons

The Penny Beliefs Scale - Weapons (PBS-W) comprises of 36 items that measure young people’s beliefs about carrying and using weapons. It was designed to facilitate our understanding of weapons carrying and use. The PBS-W has excellent internal reliability (Cronbach’s alpha of .92), extremely good test-retest consistency (ICC = .83) and is significantly positively correlated with self-reported delinquency. In order to further demonstrate the utility of the PBS-W it was compared with other measures that would be expected to be associated with weapons carrying and use. The PBS-W, the Eysenck Personality Questionnaire (EPQ-R-SV), the Maudsley Violence Questionnaire (MVQ), the Barratt Impulsiveness Scale (BIS-11), and the Brief Measure of Sensation Seeking (SS2) were administered to 189 school pupils in South Wales, aged between 16 and 18 years. Results demonstrated that the PBS-W is significantly positively correlated with EPQ Psychoticism (P), violent cognitions, impulsivity, and sensation seeking. Multiple regressions, controlling for gender and impression management (EPQ-Lie), showed that violent cognitions predicted beliefs about carrying and using weapons above and beyond P, sensation seeking and impulsivity. These findings suggest that violent cognitions are the single most powerful predictors of positive beliefs about carrying and using weapons.     

The relationship between psychopathy and impulsivity: A multi-impulsivity measurement approach

Psychopathy is a serious personality disorder of which impulsivity is a key component. However, impulsivity is a multidimensional construct, with multiple approaches to measurement, and different measures may be differentially implicated in psychopathy. This study investigated the relationship between psychopathy as assessed by the Psychopathic Personality Inventory-Revised (PPI-R; Lilienfeld & Widows, 2005), a personality measure of impulsivity (Barratt Impulsiveness Scale-11), and four behavioural measures of impulsivity (GoStop Impulsivity Paradigm, Two Choice Impulsivity Paradigm, Delay Discounting Task, Iowa Gambling Task). A nonclinical sample (N = 80) was recruited from the local community to advance understanding of psychopathy in non-incarcerated samples. The results indicated that the personality measure of impulsivity was strongly correlated with the PPI-R, while the behavioural measures were either not correlated or only weakly correlated with the PPI-R. The results are discussed in terms of the multifaceted nature of impulsivity and the need for the further development of behavioural measures of impulsivity, given their importance in clinical assessment and intervention.     

The Barratt Impulsiveness Scale-11 Among a School Sample of Portuguese Male and Female Adolescents

Few personality traits are as socially relevant as impulsivity, but few self-report measures have been specifically developed for adolescents and children. The aim of the present study was to examine the psychometric properties of the Barratt Impulsiveness Scale version 11 (BIS-11) among a mixed-gender sample of 782 Portuguese youth (M = 15.87 years; SD = 1.72), in a school context. Confirmatory factor analysis revealed the expected 6-factor first-order structure, but the 3-factor second-order factorial structure did not present a good fit. Cross-gender measurement invariance was demonstrated only in terms of weak invariance. Nonetheless, the Portuguese adaptation of the BIS-11 demonstrated some generally acceptable psychometric properties of internal consistency, mean inter-item correlation, convergent validity, discriminant validity, and criterion-related validity of statistically significant associations with conduct disorder symptoms, alcohol abuse, drug use, and unprotected sex. The use of the BIS-11 among the male and female youth population is psychometrically justified, and it can be a useful measure to identify impulsive adolescents who are at considerable risk of personal injury and present a potential source of injury to others.     

Impulsivity,self-control,and hypnotic suggestibility

Hypnotic responding might be due to attenuated frontal lobe functioning after the hypnotic induction. Little is known about whether personality traits linked with frontal functioning are associated with responsiveness to hypnotic suggestions. We assessed whether hypnotic suggestibility is related to the traits of self-control and impulsivity in 154 participants who completed the Brief Self-Control Scale, the Self-Regulation Scale, the Barratt Impulsiveness Scale (BIS-11), and the Harvard Group Scale of Hypnotic Susceptibility (HGSHS:A). BIS-11 non-planning impulsivity correlated positively with HGSHS:A (Bonferroni-corrected). Furthermore, in the best model emerging from a stepwise multiple regression, both non-planning impulsivity and self-control positively predicted hypnotic suggestibility, and there was an interaction of BIS-11 motor impulsivity with gender. For men only, motor impulsivity tended to predict hypnotic suggestibility. Hypnotic suggestibility is associated with personality traits linked with frontal functioning, and hypnotic responding in men and women might differ.     

Low temporal precision for high impulsive individuals

Previous studies have shown that impulsive people perceive time differently from non-impulsive people. However, these studies either recruited participants from the clinical population or used impulsive behavior (rather than impulsivity trait itself) as the index of impulsivity. We investigated the relationship between time perception and self-report impulsivity trait (measured by the Barratt Impulsiveness Scale; BIS-11) in non-patient participants. We used the oddball paradigm to measure subjective duration and discrimination precision in high- and low-impulsive groups. Results show that high impulsive participants’ discrimination precision was lower than low impulsive participants (Experiment 1). The possibility that this is due to high impulsive participants having weaker attentional maintenance of the task was excluded (Experiment 2). By removing potentially confounding factors that existed in previous studies, our results demonstrate a more convincing relationship between temporal precision and the impulsivity trait in healthy participants.     

How impulsiveness, trait anger, and extracurricular activities might affect aggression in school children

Individual differences in personality traits such as impulsivity and trait anger as well as environmental variables have an impact on aggressiveness. We tested a model incorporating the related variables of impulsiveness, trait anger, and aggression and incorporated the possible mediating influences of leisure-time activities. Regression analyses of data from 1129 pre-adolescents and 1093 adolescents (55.4% females) from a study evaluating the Spanish version of the Buss and Perry aggression questionnaire (AQ; Santisteban, Alvarado, & Recio, 2007) showed a relation between impulsiveness (Barratt Impulsiveness Scale) and aggression (AQ). Trait anger (Spielberger’s State-Trait Anger Expression Inventory), the time spent watching TV and playing video games, and the time spent doing homework (all related to impulsiveness) also are related to physical, as well as verbal aggression (with low to moderate coefficients). Multiple mediation analyses confirm that media violence exposure and homework, respectively, can have aggravating and attenuating effects on self-reported aggression. These results provide key variables for longitudinal studies which could reveal the causal nature of the results found with our cross-sectional design.     

Impulsivity in internet addiction: a comparison with pathological gambling

Internet addiction has been considered to be associated with poor impulse control. The aim of this study is to compare the trait impulsivity of those suffering from Internet addiction with that of individuals suffering from pathological gambling. Twenty-seven patients diagnosed with Internet addiction (age: 24.78±4.37 years), 27 patients diagnosed with pathological gambling (age: 25.67±3.97 years), and 27 healthy controls (age: 25.33±2.79 years) were enrolled in this study. All patients were men seeking treatment. Trait impulsivity and the severity of the Internet addiction and pathological gambling were measured by the Barratt Impulsiveness Scale-11, the Young's Internet Addiction Test, and the South Oaks Gambling Screen, respectively. The Beck Depression Inventory and the Beck Anxiety Inventory were also administered to all subjects. Our results show that those suffering from Internet addiction showed increased levels of trait impulsivity which were comparable to those of patients diagnosed with pathological gambling. Additionally, the severity of Internet addiction was positively correlated with the level of trait impulsivity in patients with Internet addiction. These results state that Internet addiction can be conceptualized as an impulse control disorder and that trait impulsivity is a marker for vulnerability to Internet addiction.     

Evaluating the Iowa Gambling Task as a direct assessment of impulsivity with low-income children

This study examined performance on the Iowa Gambling Task (IGT; Bechara, Damasio, Damasio, & Anderson, 1994) as a measure of low-income school-aged children’s affective decision-making and considered its utility as a direct indicator of impulsivity. One hundred and ninety-three 8–11 year olds performed a computerized version of the Iowa Gambling Task, a validated measure of decision-making. Multi-level modeling was used to examine children’s performance over the course of the task, with age, gender, and teachers’ ratings of child impulsivity (BIS-11; Patton, Stanford, & Barratt, 1995) used to predict children’s Iowa Gambling performance. Higher impulsivity scores predicted a decrease in slope of Iowa Gambling performance, indicating students rated higher on impulsivity chose more disadvantageously across the task blocks. Results support evidence of the validity of the Iowa Gambling Task as a measure of impulsivity in low-income minority children.     

Mapping self‐reported to behavioral impulsiveness: The role of task parameters

Despite being regarded as indicators of a common psychological capacity, behavioral and self‐reported measures of impulsiveness have been found to barely correlate with each other. Acknowledging the construct's multidimensional nature, the present study set out to map dissociable components of behavioral self‐control (delay discounting, response inhibition) onto lower‐order facets of self‐reported impulsiveness. In addition, we examined whether the relationship between response inhibition and self‐reported impulsiveness depends on the balance between facilitative and interfering priming processes involved in a laboratory task. In two consecutive studies, 185 participants completed laboratory self‐control tasks as well as self‐report questionnaires designed to measure facets of impulsiveness. Correlational analyses revealed an association between subscales of the Barratt Impulsiveness Scale (BIS) and response inhibition in a go/no‐go paradigm involving simultaneously presented task‐irrelevant distractors. This association vanished when an onset asynchrony between distractor and target stimuli was introduced. Previous findings regarding correlations between BIS subscales and delay discounting or intra‐individual response variability could not be replicated. Results indicate that the relationship between response inhibition and self‐reported impulsiveness critically varies as a function of subtle task parameters. Focusing on these procedural details and the multidimensionality of self‐reported impulsiveness might allow for a more differentiated analysis of the convergent validity of self‐control measures.     

越老越风险规避吗？——年龄对冲动性预测决策行为的调节效应

年老化伴随着风险承担倾向的改变,而决策行为受冲动性的影响是否受到年龄的调节尚不清楚。研究采用两种不同类型的决策任务以及Barratt冲动性量表,考察老年人风险承担在自我报告和决策行为上的改变。结果显示老年人在剑桥博弈任务中更加风险寻求而在模拟充气球任务中更加风险规避。同时冲动性可以显著预测模拟充气球的行为,且该预测受到年龄的调节。研究结果提示,老年人并不是单一的更加风险规避或者风险寻求,而是与任务特异性相关。同时,冲动性可以较好的预测年轻人的决策行为,而对老年人的决策行为没有预测作用。     

家庭功能与中学生自杀态度的关系

为考察抑郁、冲动性在家庭功能与中学生自杀态度关系中的链式中介效应,使用家庭功能问卷、抑郁自评量表、Barratt冲动性量表和自杀态度问卷对517名中学生进行调查。研究显示：（1）冲动性在家庭功能与中学生自杀态度之间具有中介作用;（2）抑郁在家庭功能与中学生冲动性之间具有中介作用。（3）抑郁在家庭功能与中学生自杀态度间具有中介作用。因此,抑郁和冲动性在家庭功能与中学生自杀态度之间起链式中介作用。     

Positive expectancies and perceived impaired control mediate the influence of reward drive and rash impulsiveness on alcohol use

Recent factor analytic studies indicate that the broad trait of impulsivity comprises at least two distinct dimensions with regard to substance use. Thus, a two-factor model of impulsivity, comprising reward drive (i.e., sensitivity to rewarding stimuli) and rash impulsiveness (i.e., rash behaviour devoid of forethought), has been proposed. It is argued that distinct cognitive processes may mediate the association of these impulsivity factors with alcohol use. Specifically, it was hypothesised that drinking expectancies would mediate the association between reward drive and alcohol use, and that perceived impaired control would mediate the effect of rash impulsiveness on alcohol. Utilising established scales, 132 participants aged 18 to 70 years were surveyed in order to assess the capacity of the two-factor model to differentially predict alcohol use through distinct cognitive mediators. The hypotheses were supported, providing support for a two-factor approach. Thus, reward drive and rash impulsiveness appear to influence alcohol use through distinct cognitive processes.     

中学生攻击性行为的注意偏向与冲动控制特征

通过注意偏向实验、BPAQ攻击问卷与Barratt冲动量表的施测,探讨中学生攻击性行为的注意偏向与冲动控制特征。研究结果发现,中学生攻击性行为及冲动控制性别差异不显著;低攻击性与高攻击性中学生表现出对攻击性刺激的注意偏向特征,在冲动控制上差异也极其显著;中学生攻击性行为与注意偏向、冲动控制总体上呈显著正相关;攻击词注意偏向与冲动控制对中学生攻击性行为具有显著预测作用。
