The influence of the frequency of cannabis use and of the five impulsivity traits on risky driving behaviors among young drivers

Concerns about road safety are at the forefront of discussions given the recent legalization of cannabis in many areas. Some studies have demonstrated that the frequency of cannabis use is a significant predictor of risky driving among young drivers. However, it is difficult to isolate the specific contribution of substance use from the influence of certain individual personality traits such impulsivity. Indeed, impulsivity traits (i.e., positive urgency, negative urgency, lack of premeditation, lack of perseverance, sensation seeking) are also correlated with risky driving. The present study examined the effect of the frequency of cannabis use on risky driving while taking into account the effect of five impulsivity traits. A community sample of 209 young drivers (aged 17–25 years) completed self-report questionnaires about their road behaviors, their cannabis use, and their impulsivity traits. The results showed that the frequency of cannabis use was significantly associated with risky driving beyond the five impulsivity traits measured. Positive urgency was the only impulsivity trait that remained significantly associated with risky driving once all covariates were entered into the model. Moreover, the frequency of cannabis use acted as a mediator in the relationship between sensation seeking and risky driving.     

Impulsivity partially mediates the relationship between BIS/BAS and risky health behaviors

Several theorists have suggested that impulsivity can be understood as a joint function of the behavioral approach (BAS) and behavioral inhibition systems (BIS). After resolving questions concerning the measurement of impulsivity and BAS, this study examined the relationships among risky health behaviors, impulsivity, BIS, and BAS. Utilizing a sample of undergraduates (N = 904), a structural model was tested in which BAS and BIS predicted impulsivity, which, in turn, predicted risky behavior. Fit indices were acceptable, but not good. A modified version of the model showed a statistically significant negative relationship between BAS and risky behaviors. However, the fit indices were not unequivocally supportive of the need to include that path. Overall, the data suggest that impulsivity is the joint result of countervailing motivational forces and that it partially or fully mediates the influence of BIS and BAS on risky health behavior.     

Aspects of impulsivity are differentially associated with risky sexual behaviors

Risky sexual behavior (RSB) greatly increases the risk of contracting sexually transmitted infections, including HIV, as well as a host of other negative outcomes. Recent advances in personality research have defined multiple and separate dispositions to engagement in impulsive behaviors, including RSB. Little is known concerning the ways in which aspects of impulsivity place individuals at risk for various types of RSB. The purpose of the current study, therefore, was to further clarify the unique ways in which aspects of impulsivity were differentially associated with various forms of RSB within a large, diverse sample of university students ages 18-to-24 years (N = 917). Results suggest low self-control confers a general risk while a tendency toward impulsive behavior in the context of intense emotion confers a more specific risk as for various types of RSB. The current study confirms the importance of focusing on both various pathways to impulsive behaviors as well as specific types of RSB.     

Impulsivity facets and cognitive distortions associated with problem gambling: Differences between ADHD and non-ADHD gamblers

ObjectiveTo compare the association between (1) impulsivity facets or cognitive distortions, and (2) problem gambling between male gamblers with versus without self-reported Attention-Deficit/Hyperactivity Disorder (ADHD).MethodIn 287 male gamblers recruited online, we assessed problem gambling (South Oaks Gambling Screen; cut-off ≥ 3), Adult ADHD Self-report Scale-V1.1 (ADHD), impulsivity facets (UPPS Impulsive Behavior Scale-short version) and gambling-related cognitions (Gambling-Related Cognitions Scale).ResultsThe prevalence of self-reported ADHD was 21.6%. In both ADHD and non-ADHD groups, problem gambling was associated with negative urgency, positive urgency and the same cognitive distortions. Sensation seeking and lack of premeditation were associated with problem gambling, but only in non-ADHD gamblers (significant interaction effect).ConclusionDifferent impulsivity facets, but not different cognitive distortions, are associated with problem gambling in male gamblers with or without ADHD. Emotion dysregulation (positive and negative urgency) and cognitive distortions are involved in both groups, but sensation seeking and lack of premeditation may be specific to non-ADHD problem gamblers.     

Urgency and negative emotions: Evidence for moderation on negative alcohol consequences

Prior research had shown that impulsivity may enhance the impact of negative emotions on alcohol related problems. However, these studies used broad measures of both negative emotions and impulsivity that may have obscured the effects of more specific constructs of impulsivity or negative emotions. One such construct is urgency, which is defined as the tendency to act impulsively in the face of strong positive emotions (positive urgency) or negative emotions (negative urgency). The present study tested whether urgency moderated the association between separate negative emotions (anger, depression and anxiety) and alcohol related problems. Data were obtained from a large online sample of currently drinking college students attending a large Northwestern university (n = 442). Findings indicated that alcohol related problems were directly associated with anger and both urgency facets. Additionally, positive urgency, but not negative urgency, enhanced the effects of depression, while the buffering effects of positive urgency on the anxiety-consequences association approached significance. These results suggest the importance of emotional context in understanding how dispositions towards rash action may lead to problematic alcohol use.     

The impact of depressive symptomatology on risky sexual behavior and sexual communication among African American female adolescents

Adolescents, particularly African American adolescents, are at high risk for sexually transmitted infections (STIs). The association between psychosocial factors and risky sexual behavior has been well established. However, only a small number of studies have examined the relationship between depressive symptomatology among African American female adolescents, specifically over time. The present study examined depressive symptoms as a predictor of risky sexual behavior, sexual communication, and STIs longitudinally among African American female adolescents between the ages 15 and 21. Binary generalized estimating equation models were conducted assessing the impact of depressive symptoms at baseline on risky sexual behavior and STIs over six- and 12-months follow-up. Age, intervention group, and baseline outcome measures were entered as covariates. The results indicated that high levels of depressive symptoms predicted no condom use during last sexual encounter and multiple sexual partners over six-months follow-up. Depressive symptoms also predicted having a main partner with concurrent partners, high fear of communication about condoms, and sex while high on alcohol or drugs over six- and 12-months follow-up. These findings could be used to inform HIV/STI prevention intervention programs and clinicians providing regular health care maintenance to African American female adolescents engaging in risky sexual behavior.     

Marijuana use and risky sexual behavior among high-risk adolescents: Trajectories, risk factors, and event-level relationships

Adolescents involved with the juvenile justice system have a high incidence of risky sexual behaviors resulting in unintended pregnancy and sexually transmitted infections. Substance use may be particularly important as a risk factor for unsafe sexual behavior for this group, and recent evidence suggests a possible association between marijuana use and risky sexual behavior. Adolescents (n = 728; 33% female) on probation were followed for 2 years, at intervals of 6 months, to explore the association of marijuana use and condom use longitudinally and at a specific intercourse occasion. Latent growth curve modeling indicated that greater marijuana use at baseline was associated with a steeper decline in condom use over the 2-year period of the study. In-depth analysis of the most recent intercourse occasion suggested that condom use was less likely if marijuana was being used by the participant or his/her partner and that this association was more pronounced if intercourse occurred with someone the participant had just met. Implications for the prevention of risky sexual behavior in this population are discussed. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

Illicit drug use and risky sexual behavior among African American and Puerto Rican urban adolescents: the longitudinal links

The authors assessed whether (a) early illicit drug use predicted later risky sexual activity, (b) early risky sex predicted later illicit drug use, and (c) common factors affected both risky sexual behavior and illicit drug use. African American and Puerto Rican youth completed questionnaires in their classrooms at Time 1 (T1) and face-to-face interviews with the authors in their homes 5 years later at Time 2 (T2). Logistic regression analyses showed the association between T1 illicit drug use and T2 risky sexual activity and between T1 risky sexual behavior and T2 illicit drug use. With few exceptions, T1 illicit drug use was associated with all of the T2 risky sexual behaviors. After controlling for demographic factors, the authors found that multiple sex partners at T1 was not related to illicit drug use at T2. Condom use at T1 was related to illicit drug use at T2, whereas sexually transmitted diseases and adolescent pregnancy were not related to this drug use. The findings indicated that assessments of and treatments for substance use should focus on the risky sexual behaviors that seem to accompany illicit drug use.     

A French adaptation of the internal and external encoding style questionnaire and its relationships with impulsivity

Recent research has revealed the existence of individual differences in how preexisting schemata (versus cues from the outside world) affect encoding processes, which can be reliably assessed with the internal and external encoding style questionnaire (ESQ) [Lewicki, P. Internal and External Encoding Style and Social Motivation. In: J. P. Forgas, K. D. Williams, S. M. Laham, (Eds.), Social Motivation: Conscious and Unconscious Processes. Psychology Press, New York (2005). pp. 194–209]. The present study was designed to (1) test the psychometric properties of a French version of the ESQ and (2) explore in-depth its relationship with impulsivity – a trait of central importance in the understanding of emotional psychopathology, and which has been previously related to the internal encoding style. Sixty-three participants were tested using the French versions of the ESQ and the UPPS impulsive behavior scale. The UPPS identifies four distinct facets of impulsivity: urgency, lack of premeditation, lack of perseverance, and sensation seeking. The results showed (1) that the French version of the ESQ has good psychometric properties and (2) that consistent with theoretical considerations, internal encoding style is related to two specific out of the four components of impulsivity: high urgency and low perseverance.     

Secondary psychopathy,but not primary psychopathy,is associated with risky decision-making in noninstitutionalized young adults

Although risky decision-making has been posited to contribute to the maladaptive behavior of individuals with psychopathic tendencies, the performance of psychopathic groups on a common task of risky decision-making, the Iowa Gambling Task (IGT; Bechara, Damasio, Damasio, & Anderson, 1994), has been equivocal. Different aspects of psychopathy (personality traits, antisocial deviance) and/or moderating variables may help to explain these inconsistent findings. In a sample of college students (N = 129, age 18–27), we examined the relationship between primary and secondary psychopathic features and IGT performance. A measure of impulsivity was included to investigate its potential as a moderator. In a joint model including main effects and interactions between primary psychopathy, secondary psychopathy and impulsivity, only secondary psychopathy was significantly related to risky IGT performance, and this effect was not moderated by the other variables. This finding supports the growing literature suggesting that secondary psychopathy is a better predictor of decision-making problems than the primary psychopathic personality traits of lack of empathy and remorselessness.     

Cue-elicited negative affect in impulsive smokers.

Impulsivity is associated with cigarette smoking, but the nature of this relationship and the mechanisms that maintain it are relatively unknown. The relationship has often been thought to reflect appetitive processes, but research suggests that an affective pathway exists as well. The present study tested the effect of impulsivity on affective responses to an environmental smoking cue. Adult smokers (N=62) were exposed to a neutral cue and a smoking cue in separate experimental sessions in a repeated-measures design. Mixed-effects regression analyses showed that larger postexposure increases in negative affect were associated with high scores on 2 facets of impulsivity: urgency, t(179)=6.16, p<.001, and sensation seeking, t(179)=4.75, p<.001. Heightened impulsivity was associated with lower levels of positive affect generally but not with positive affective responses to cue exposure. Findings provide support for the existence of a negative affective pathway linking impulsivity and cigarette smoking, and they suggest that this pathway may be specific to the urgency and sensation-seeking components of impulsivity.     

Body image and risky sexual behaviors: an investigation in a tri-ethnic sample

The impact of negative body image on risky sexual behaviors has not been extensively investigated. The present study examined the relationship between two aspects of body image, appearance shame and appearance investment, and potentially risky behaviors. The study employed a tri-ethnic sample of 1547 women seeking services at two family planning clinics. Logistic regression was utilized to examine the relationship between potential risk behaviors and shame and investment. Results supported that these aspects of body image were significant predictors of inconsistent condom use, having multiple sex partners in the past year, and having sex after drinking alcohol or using drugs, and that demographic variables (e.g., age, marital status, ethnicity) could not fully account for these relationships. The importance of future research investigating the relationships among body image, perceived relationship security, affect-management strategies, and risky sexual behaviors is emphasized.     

Common genetic influences on impulsivity facets are related to goal management,psychopathology, and personality

In this study, we characterized the genetic/environmental commonality and heterogeneity of impulsivity facets and tested the hypothesis that goal-management is central to their common variance. 764 young-adult twins completed the UPPS-P Impulsive Behavior Scale and measures of goal management, personality, and psychopathology. We found common genetic influences across all impulsivity facets except sensation seeking. These impulsivity genetic influences explained 40.0% of variance in goal-management ability. Other results supported three hypotheses concerning heterogeneity: that sensation seeking is independent of other facets, that urgency is more related to psychopathology than lack of premeditation, and that lack of perseverance is more similar to urgency than lack of premeditation. Thus, impulsivity facets show considerable heterogeneity in addition to common variation related to goal-management abilities.     

Rethinking impulsivity in suicide

Elevated impulsivity is thought to facilitate the transition from suicidal thoughts to suicidal behavior. Therefore, impulsivity should distinguish those who have attempted suicide (attempters) from those who have only considered suicide (ideators-only). This hypothesis was examined in three large nonclinical samples: (1) 2,011 military recruits, (2) 1,296 college students, and (3) 399 high school students. In sample 1, contrary to traditional models of suicide risk, a unidimensional measure of impulsivity failed to distinguish attempters from ideators-only. In samples 2 and 3, which were administered a multidimensional measure of impulsivity (i.e., the UPPS impulsive behavior scale; Whiteside & Lynam, 2001), different impulsivity-related traits characterized attempters and ideators-only. Whereas both attempters and ideators-only exhibited high urgency (the tendency to act impulsive in the face of negative emotions), only attempters exhibited poor premeditation (a diminished ability to think through the consequences of one's actions). Neither attempters nor ideators-only exhibited high sensation seeking or lack of perseverance. Future research should continue to distinguish impulsivity-related traits that predict suicide ideation from those that predict suicide attempts, and models of suicide risk should be revised accordingly.     

A state model of negative urgency: Do momentary reports of emotional impulsivity reflect global self-report?

Negative urgency is a trait that is a risk factor for a range of psychopathology. Yet, little research has tested whether global self-report measures of negative urgency truly reflect a heightened association between real-world negative emotions and impulsive behaviors. In a sample of young adults (N = 222) assessed 3 times per day for 10 days, we tested whether negative emotions were associated with multiple facets of impulsivity at the state-level, and whether those associations were moderated by global self-report of negative urgency. Our findings suggest a robust within-person association between negative affect and acting on impulse. However, global self-report of negative urgency did not moderate any emotion-impulsivity association we tested.     

Impulsivity and Nonsuicidal Self-Injury: Examining the Role of Affect Manipulation

The assessment of impulsivity is complicated by the construct’s multi-faceted nature and poor correspondence between self-report and behavioral measures. These complications extend to populations anecdotally described as impulsive, including individuals who engage in nonsuicidal self-injury (NSSI). Research suggests that self-injurers report impulsivity, primarily negative urgency. Thus, negative affect may be an important prerequisite for increased impulsive behaviors. The present laboratory study examined self-report impulsivity differences between individuals with and without a history of NSSI and if self-injurers demonstrated behavioral impulsivity when experiencing negative affect. Undergraduates with (N?=?54) and without (N?=?61) a history of NSSI participated in a two-part laboratory-based study that investigated the role of affect manipulation in impulsivity and NSSI. Participants were randomly assigned to either a negative or a neutral-relaxing mood induction. Participants completed self-report measures of impulsivity, NSSI, and negative affect. A behavioral measure of impulsivity was administered during Session 1 (prior to a mood induction task) and again during Session 2 (following a mood induction task) to determine whether affect had an effect on behavioral impulsivity task performance. Self-injurers reported higher negative urgency and lack of perseverance but did not display impulsivity on the behavioral task, even under conditions of negative affect.     

Driving self-regulation and risky driving outcomes

Self-regulation has been associated with risky driving outcomes in the past but there are no available measures to assess driving-specific self-regulatory capacity. The present study assessed the association of a newly developed driving self-regulation measure with driving violations, errors, and lapses. Overall, 330 UK drivers completed measures of risky driving outcomes, driving anger, trait impulsivity, sensation seeking, normlessness, domain-general trait self-regulation plus a new unidimensional measure of Driving Self-Regulation Questionnaire (DSRQ-16). Bivariate correlation analysis indicated that the DSRQ-16 showed expected associations with both driving-related outcomes and factors, as well as with impulsivity traits and general self-regulation. Bootstrapped hierarchical linear regression models showed that the DSRQ-16 was significantly associated with driving violations, errors, and lapses after controlling for the effects of other relevant predictors. This is the first study to demonstrate the association of driving-specific self-regulation with risky driving behaviour, driving anger, impulsivity and related personality traits. Driving-specific self-regulation may present a novel target for road safety interventions, as well as a theoretically relevant component of models of risky driving behaviour.     

Integration of impulsivity and positive mood to predict risky behavior: development and validation of a measure of positive urgency

In 3 studies, the authors developed and began to validate a measure of the propensity to act rashly in response to positive affective states (positive urgency). In Study 1, they developed a content-valid 14-item scale, showed that the measure was unidimensional, and showed that positive urgency was distinct from impulsivity-like constructs identified in 2 models of impulsive behavior. In Study 2, they showed that positive urgency explained variance in risky behavior not explained by measures of other impulsivity-like constructs, differentially explained positive mood-based risky behavior, differentiated individuals at risk for problem gambling from those not at risk, and interacted with drinking motives and expectancies as predicted to explain problem drinking behavior. In Study 3, they confirmed the hypothesis that positive urgency differentiated alcoholics from both eating-disordered and control individuals.
