Negative Urgency: A Personality Predictor of Externalizing Behavior Characterized by Neuroticism, Low Conscientiousness, and Disagreeableness

Negative urgency, the tendency to act rashly when distressed, is characterized by high Neuroticism, low Conscientiousness, and low Agreeableness. Because of this set of characteristics, the authors hypothesized that (1) negative urgency (NU) is a particularly important predictor of externalizing dysfunction; (2) traits that reflect primarily high Neuroticism predict internalizing dysfunction; and (3) traits that reflect primarily low Conscientiousness predict those types of externalizing dysfunction that include intense affect less strongly than does NU. In three studies, the authors showed that negative urgency concurrently predicted alcohol dependence symptoms in disordered women, drinking problems and smoker status in preadolescents, and aggression, risky sex, illegal drug use, drinking problems, and conduct disordered behavior in college students. High Neuroticism traits predicted internalizing dysfunction but predicted none of these externalizing criteria beyond negative urgency. Low Conscientiousness did not add to prediction from negative urgency, except in a few cases. The tendency toward affect-driven rash action may underlie many externalizing behaviors.

Risk factors for elementary school drinking: pubertal status, personality, and alcohol expectancies concurrently predict fifth grade alcohol consumption.

Little is known about the correlates and potential causes of very early drinking. The authors proposed this risk theory: (a) pubertal onset is associated with increased levels of positive urgency (the tendency to act rashly when experiencing intensely positive mood), negative urgency (the tendency to act rashly when distressed), and sensation seeking; (b) those traits predict increased endorsement of high-risk alcohol expectancies; (c) the expectancies predict drinker status among fifth graders; and (d) the apparent influence of positive urgency, negative urgency, and sensation seeking on drinker status is mediated by alcohol expectancies. The authors conducted a concurrent test of whether the relationships among these variables were consistent with the theory in a sample of 1,843 fifth grade students. In a well-fitting structural model, their hypotheses were supported. Drinker status among fifth graders is not just a function of context and factors external to children: it is predictable from a combination of pubertal status, personality characteristics, and learned alcohol expectancies.

The role of negative urgency and expectancies in problem drinking and disordered eating: testing a model of comorbidity in pathological and at-risk samples.

The aim of this study was to test hypotheses derived from a model that explains both the comorbidity of problem drinking and eating disorder symptoms and the difference in risk process between the two disorders. In Study One, the authors examined four personality constructs typically associated with rash action (sensation seeking, lack of planning, lack of persistence, and negative urgency) and disorder-specific expectancies in samples of women with eating disorders, substance dependence disorders, comorbid conditions, and no symptoms (N = 104). Negative urgency, the tendency to act rashly when distressed, differentiated the disordered groups from the control group. In contrast, learned expectancies differentiated among clinical groups. Women with eating disorders endorsed high levels of eating and dieting expectancies and women with substance use disorders endorsed high levels of alcohol expectancies, while comorbid women endorsed high levels of both. In Study Two, this pattern of findings was replicated in a sample of fifth grade girls (N = 905). Girls who had engaged in binge eating, alcohol use, or both had higher levels of negative urgency than asymptomatic girls, and the pattern of outcome expectancy endorsement was disorder specific. Negative urgency may represent a general, personality influence on both eating disordered behaviors and symptoms of alcohol dependence, which, when combined with learned, behavior-specific expectancies, leads to specific addictive behavior patterns.

Applying the Attention-Allocation Model to the Explanation of Alcohol-Related Aggression: Implications for Prevention

The primary purpose of this article is to apply the attention-allocation model (AAM; ) to the explanation, as well as the prevention, of alcohol-related violence. The AAM contends that alcohol has a “myopic” effect on attentional capacity that presumably facilitates aggression by narrowing attentional focus on the most salient provocative cues that are naturally present in hostile situations, rather than on less salient inhibitory cues. Data are presented to demonstrate support for the AAM with regard to alcohol-related aggression. The model has also been expanded to suggest some intermediary mechanisms that may account for how distracting attention away from provocative cues might be involved in the reduction of aggression. Finally, a number of practical suggestions are put forth regarding how the AAM can be applied to the prevention of intoxicated aggression.

The Effects of a Working Memory Load on Delay Discounting in Those With Externalizing Psychopathology

This study investigated the influence of executive working memory (EWM) capacity on impulsive decision making in a sample of young adults (N = 623) who varied in degree of externalizing psychopathology (EXT) by examining (a) the effects of WM load on delay discounting rates and (b) the association between EWM capacity and delay discounting rates. EXT was measured as a latent variable indicated by lifetime problems with alcohol, marijuana, nicotine, other drugs, childhood conduct, and adult antisocial behavior. Results showed that (a) the WM load increased discounting rates throughout the spectrum of EXT, (b) EXT was associated with higher discounting rates and lower EWM capacity, and (c) EWM capacity was significantly associated with higher discounting rates when controlling for IQ, but only after a WM load. The results are discussed in terms of the role of EWM capacity in impulsive decision making in EXT.

Dimensions of disinhibited personality and their relation with alcohol use and problems

Although alcohol use disorders (AUDs) have been associated with different aspects of disinhibited personality and antisociality, less is known about the specific relationships among different domains of disinhibited personality, antisociality, alcohol use, and alcohol problems. The current study was designed to address three goals, (i) to provide evidence of a three-factor model of disinhibited personality (comprised of impulsivity [IMP], risk taking/low harm avoidance [RTHA], excitement seeking [ES]), (ii) to test hypotheses regarding the association between each dimension and alcohol use and problems, and (iii) to test the hypothesis that antisociality (social deviance proneness [SDP]) accounts for the direct association between IMP and alcohol problems, while ES is directly related to alcohol use. Measures of disinhibited personality IMP, RTHA, ES and SDP and alcohol use and problems were assessed in a sample of young adults (N=474), which included a high proportion of individuals with AUDs. Confirmatory factor analyses supported a three-factor model of disinhibited personality reflecting IMP, RTHA, and ES. A structural equation model (SEM) showed that IMP was specifically associated with alcohol problems, while ES was specifically associated with alcohol use. In a second SEM, SDP accounted for the majority of the variance in alcohol problems associated with IMP. The results suggest that aspects of IMP associated with SDP represent a direct vulnerability to alcohol problems. In addition, the results suggest that ES reflects a specific vulnerability to excessive alcohol use, which is then associated with alcohol problems, while RTHA is not specifically associated with alcohol use or problems when controlling for IMP and ES.

Marijuana use is associated with alcohol use and consequences across the first 2 years of college.

College entry is associated with marijuana initiation, and co-use of alcohol and marijuana is associated with problematic outcomes, including alcohol-related consequences. The present study explored if: (a) use of marijuana on a given day would be associated with greater alcohol use within the same day; (b) use of marijuana within a given week would be associated with increased alcohol-related consequences in that same week; and (c) the association between marijuana use and alcohol consumption and consequences varies across time or by precollege level of problematic alcohol use. Participants (N = 488 college student drinkers, 59% female) completed assessments of marijuana use, alcohol use, and alcohol consequences across 2 years. Analyses revealed: (a) daily marijuana use predicted greater number of daily drinks and estimated breath alcohol concentration; (b) weekly marijuana use predicted more weekly positive and negative alcohol consequences; (c) the effect of daily marijuana use on alcohol use strengthened over time, while the effect of weekly marijuana use on positive alcohol consequences reduced over time; and (d) precollege level of problematic alcohol use moderated the association between daily marijuana and alcohol use and weekly marijuana use and negative consequences. This study provides the first longitudinal evidence of the association between marijuana use and greater alcohol use and consequences in college students. Future research examining event-level measurement of alcohol and marijuana co-use is important for the prevention of alcohol-related consequences.
