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.

A longitudinal transactional risk model for early eating disorder onset.

The presence of binge eating behavior in early middle school predicts future diagnoses and health difficulties. We showed that this early binge eating behavior can be predicted by risk factors assessed in elementary school. We tested the acquired preparedness model of risk, which involves transactions among personality, psychosocial learning, and binge eating. In a sample of 1,906 children assessed in the spring of fifth grade (the last year of elementary school), the fall of sixth grade, and the spring of sixth grade, we found that fifth grade negative urgency (the personality tendency to act rashly when distressed) predicted subsequent increases in the expectancy that eating helps alleviate negative affect, which in turn predicted subsequent increases in binge eating behavior. This transactional risk process appeared to continue to occur at later time points. Negative urgency in the fall of sixth grade was predicted by fifth grade pubertal onset, binge eating behavior, and expectancies. In turn, it predicted increases in high-risk eating expectancies by the spring of sixth grade, and thus heightened risk.

An exploration of sexual victimization and academic performance among college women

The literature has documented the widespread nature of sexual assault victimization among college women. While the aftermath of violence against university women has also received focus, that is, documenting trauma-related sequelae; risk factors; reporting patterns; and legal interventions, the impact on academic performance has not received adequate attention in the literature. The primary purpose of this study was to explore the association of rape and sexual assault with academic performance among college women. Its specific aims included the following: to compare high school and college sexual assault experiences with collegiate grade point averages (GPAs) at key points in time; to examine any differences in GPA by type of sexual assault; to urge researchers studying retention and persistence patterns or sexual assault among college students to ensure that the relationship between the two is included in research designs; and to recommend that academic institutions expand programming on retention to include rape and sexual assault among the risk factors associated with a lack of persistence.

The measurement of dispositions to rash action in children.

Among adolescents and adults, there appear to be at least four different personality traits that dispose individuals to rash or ill-advised action: sensation seeking, negative urgency, lack of planning, and lack of perseverance. The four are only moderately correlated and they appear to play different roles in dysfunction. It is important to determine whether the traits are present among preadolescents because of their possible influence on subsequent development. The authors developed assessments of the four traits for preadolescent children and found evidence supporting (a) the internal consistency of each trait measure, (b) the convergent and discriminant validity of the four measures using the multitrait, multimethod technique, and (c) the hypothesis that the different traits correlated with different dysfunctional behaviors as predicted by theory. Pending further validation efforts, it appears to be the case that researchers may be able to distinguish among different dispositions to rash action prior to adolescence.

Experimental effect of positive urgency on negative outcomes from risk taking and on increased alcohol consumption

The current pair of experimental studies sought to further validate the role of positive urgency (acting rashly when in an extreme positive emotional state) as a risk factor for impulsive and maladaptive behavior. Previous research has supported the use of emotion-based dispositions to rash action in predicting a wide range of maladaptive acts. However, that research was conducted in the field and relied on self-reported behavior, thus lacking tight experimental controls and direct observation of risky behaviors. In the 2 experimental studies described here, we found that among college students (1) positive urgency significantly predicted negative outcomes on a risk-taking task following a positive mood manipulation (n = 94), and (2) positive urgency significantly predicted increases in beer consumption following positive mood induction (n = 33). Positive urgencys role was above and beyond previously identified risk factors; these findings, combined with prior cross-sectional and longitudinal field studies, provide support for the role of positive urgency in rash action.

A risk model for preadolescent disordered eating

OBJECTIVE This study tested this risk model for disordered eating in preadolescent girls: pubertal onset is associated with increases in negative urgency (the personality tendency to act rashly when distressed); negative urgency influences eating disorder symptoms by shaping psychosocial learning (expectancy formation), thus indirectly influencing symptom levels; and many influences on purging are mediated by binge eating. METHOD Nine hundred five fifth grade girls completed questionnaire measures of eating pathology, negative urgency, and dieting/thinness and eating expectancies. RESULTS Binge eating and purging behaviors were present in fifth grade girls. As anticipated, pubertal status was associated with higher levels of negative urgency, negative urgency was associated with each expectancy measure, quadratic dieting/thinness and eating expectancies were associated with binge eating, and binge eating was associated with purging. DISCUSSION It is important and feasible to develop risk models for preadolescent eating disordered behaviors. Our model that integrates puberty, personality, and psychosocial learning appears promising.

Clarifying the Construct of Perfectionism

The construct of perfectionism is related to many important outcome variables. However, the term perfectionism has been defined in many different ways, and items comprising the different existing scales appear to be very different in content. The overarching aim of the present set of studies was to help clarify the specific unidimensional personality constructs that contribute to perfectionistic behavior. First, trained raters reliably sorted items from existing measures of perfectionism into nine dimensions. An exploratory factor analysis, followed by a confirmatory factor analysis on an independent sample, resulted in a 9-scale, 61-item measure, called the Measure of Constructs Underlying Perfectionism. The nine scales were internally consistent and stable across time, and they were differentially associated with relevant measures of personality in theoretically meaningful ways.

Preadolescent Disordered Eating Predicts Subsequent Eating Dysfunction

OBJECTIVE This article tested whether disordered eating in the spring of sixth grade can be predicted by the behaviors of fifth grade elementary school children. METHOD Measurements of disordered eating were collected from 1906 children (mean age = 10.86 years) at Time 1 (spring of fifth grade), Time 2 (fall of sixth grade), and Time 3 (spring of sixth grade). RESULTS A number of fifth grade children reported disordered eating during the previous 2 weeks: 12.1% reported objective binge episodes, 4.8% reported purging food, and 9.8% reported restricting food intake. These behaviors predicted disordered eating during the spring of sixth grade. In addition, fifth grade pubertal onset predicted higher levels of restricting for girls. CONCLUSION A substantial number of fifth grade children reported disordered eating behaviors, and these behaviors predicted disordered eating behaviors in the spring of sixth grade. Disordered eating can be studied at least as early as fifth grade.

A risk model for disordered eating in late elementary school boys.

The authors tested the following risk model for disordered eating in late elementary school-age boys: Pubertal status is associated with increases in negative urgency, that is, the tendency to act rashly when distressed; high levels of negative urgency then influence binge eating through psychosocial learning; and binge eating influences purging. A sample of 908 fifth-grade boys completed questionnaire measures of puberty, negative urgency, dieting/thinness and eating expectancies, and eating pathology. Eating disorder symptoms were present in these young boys: 10% reported binge eating and 4.2% reported purging through self-induced vomiting. Each hypothesis in the risk model was supported. Boys this young do in fact engage in the maladaptive behaviors of binge eating and purging; it is crucial to develop explanatory risk models for this group. To this end, it appears that characteristics of boys, including their pubertal status, personalities, and psychosocial learning, help identify boys at risk.

The acquired preparedness risk model applied to smoking in 5th grade children

The very early onset of smoking predicts numerous health problems. The authors conducted the first test of one risk model for elementary school age smoking, known as the acquired preparedness (AP) model of risk, in a cross-sectional sample of 309 5th grade children. The model posits that (a) impulsivity-related personality traits contribute to risk for a variety of risky, maladaptive behaviors; (b) smoking expectancies confer risk only for smoking; and (c) the personality traits contribute to the formation of high risk expectancies for reinforcement from smoking, which in turn increases the likelihood of early onset smoking. The model was supported: the high-risk personality traits distinguished children engaging in any risky, maladaptive behavior from other children, and the smoking expectancies differentiated smokers from all other children. The relationship between personality tendencies to act rashly when experiencing intense positive or negative emotions and smoker status was partially mediated by expectancies for reinforcement from smoking. This model should be investigated longitudinally.
