Predictors of women's aggressive driving behavior

Predictors of women's aggressive driving behavior were explored in a study involving 256 female motorists. Sex role orientation, dispositional aggressiveness, age, and annual mileage were measured as independent variables, and aggressive driving behavior was included as the dependent variable. Stepwise hierarchical regression analysis showed that age was negatively related to driving aggression, whereas annual mileage had a positive relationship with driving aggression. Dispositional aggressiveness was a significant predictor of driving aggression. Of the two components of sex role orientation, only femininity was associated with driving aggression, with higher femininity scores predicting lower aggressive driving scores. Masculinity failed to predict aggressive driving, as did the interaction of masculinity and femininity. In combination, the predictors explained 29% of the variance in women's aggressive driving. The results are discussed with respect to the role of dispositional variables as predictors of driving aggression in women. Aggress. Behav. 00:1–10, 2005. © 2005 Wiley‐Liss, Inc.     

Relation between resilience and personality traits: The role of hopelessness and age

Resilience refers to the process by which individuals use the ability to cope with challenges to successfully adapt to adverse situations, inclining towards the future and hope. The main aim of this study was to analyze the relation between resilience, personality traits, and hopelessness. Furthermore, we conducted comparisons between two age groups: young and older adults. The sample comprised 439 Spanish participants (66.7% women; M = 43.73, SD = 26.41; age range = 18–98 years). The Connor–Davidson Resilience Scale, NEO-Five Factor Inventory, and Beck Hopelessness Scale were used to measure the main study variables. The results revealed a negative relation between resilience and neuroticism, and a positive association with the other personality traits. Additionally, levels of resilience were found to be negatively related to hopelessness. The group of older adults showed significantly lower resilience levels than the young adults, although age was not a significant predictor of resilience. Neuroticism, extraversion, openness, and hopelessness were the only predictors of resilience for the current study. This work contributes to the study of resilience and related factors, by attempting to understand the role of resilience and resistance to risk and how individuals tackle challenges over time, with important implications for mental health.     

The influence of just-world beliefs on driving anger and aggressive driving intentions

Decades of research demonstrate that the extent to which one believes the world is just can have important interpersonal consequences. Unfortunately, most of the commonly studied consequences are negative in nature. Guided by previous research demonstrating the buffering effect of just‐world beliefs and anger, the present research explores how belief in a just world (BJW) may mitigate anger in the domain of driving anger and examines the limiting conditions of this effect. Study 1 demonstrated the expected negative relation between common measures of BJW and anger expression in a driving context. Study 2 found that the buffering effects of just‐world beliefs and driver aggression were greater when BJW was violated (vs. not). Study 3 replicated the effects on aggression and anger and established a mediational role of anger on the buffering effects of just‐world beliefs on thoughts and driver aggression. Aggr.

Externalizing behavior trajectories: The role of parenting, sibling relationships and child personality

Based on longitudinal multilevel modeling and using a multi-informant strategy, this study examines trajectories of externalizing problem behavior (EPB) in childhood as predicted by parental behavior (absolute level of parenting [ALP] and parental differential treatment [PDT]), parental self-efficacy (PSE), child personality and sibling relationships. Besides main effects, several interactions were tested. The effects of changes in parenting on changes in EPB were also examined. A total of 119 families from the French-speaking area of Belgium rearing a child (3- to 5-year-olds at the onset of the study) referred for EPB were studied. The effects of both level-of and changes-in mothers' ALP were partially confirmed, but for fathers, only ALP was predictive. There were some significant interactions between ALP and PDT for both parents. Mothers' PSE explained some variance in EPB, additional to that explained by the parenting measures. Some parenting by personality and by sibling relationship interactions were found.     

Convergent,discriminant, and predictive validity of aggressive driving inventories: they drive as they live

The authors hypothesized that aggressive driving is indicative of a more general trait that leads individuals to behave aggressively in different situations. This hypothesis was tested by having 85 male and 237 female undergraduates complete the Aggression Questionnaire, three measures of aggressive driving (the Driver Anger Scale, Driver Vengeance Questionnaire, and Driving Behavior Inventory), and questions about violating traffic laws. High correlations among the aggressive driving inventories provided evidence for the convergent validity, but a confirmatory factor analyses raised questions about the discriminant validity of aggressive driving inventories. The inventories did not attain significance in hierarchical analyses of traffic violations that controlled for gender, driving experience, and measures of trait aggression. It is concluded that there is little unique about aggressive driving and that individuals drive as they live. Aggr. Behav. 32:89–98, 2006. © 2006 Wiley‐Liss, Inc.     

The different effects of personality on prosocial and aggressive driving behaviour in a Chinese sample

Dangerous driving behaviours, as a direct cause of accidents and death, are the focus of considerable research attention. However, unlike unsafe driving behaviours, few studies have explored safe driving behaviours and their effects on road traffic. This study aims to verify the Chinese version of the Prosocial and Aggressive Driving Inventory (PADI) and then investigate the relationship between personality and aggressive/prosocial driving behaviours. A total of 303 licensed drivers were recruited, and they voluntarily and anonymously completed the PADI, the Driving Behaviours Questionnaire (DBQ), and personality scales (anger, sensation-seeking and altruism). The results of this research confirmed the reliability and validity of the Chinese PADI. Most importantly, it was found that different relationships between different personalities and aggressive/prosocial driving behaviours. Specifically, individuals with high altruism exhibited more prosocial driving behaviours, while individuals with high sensation seeking presented more aggressive driving behaviours. The importance of these findings lies in two main potential implications: developing an effective measurement of prosocial driving behaviours in China and providing favourable evidence to guide drivers toward more prosocial driving behaviours.     

Effects of reactivity to dorsal stimulation and social role on aggressive behavior in laboratory rats

Rats were selected on the basis of reactivity to dorsal tactile stimulation and then tested in a resident-intruder paradigm. While reactivity of residents did not influence the occurrence of agonistic behaviors or wounding of residents and intruders, reactivity of intruders did affect offensive and defensive patterns of interactions and the wounds sustained by residents and intruders. Subsequent to resident-intruder testing, rats were tested for shock-induced aggression. The pattern of the results and the results of additional experiments demonstrated that resident-intruder experience could affect subsequent shock-induced aggressive behavior.     

Salivary testosterone and self-report aggressive and pro-social personality characteristics in men and women

Measures of salivary testosterone and the personality dimensions of aggression and pro-social behavior were obtained in 306 (155 male and 151 female) university students. Each participant provided two samples of saliva and completed ten self-report personality scales from multiple inventories. A factor analysis of the personality scales produced two factors, an aggression factor and a pro-social behavior factor. Men averaged five times the amount of salivary testosterone as women (99 pg/ml vs. 18.5 pg/ml) and rated themselves as more aggressive and less nurturant. Within each sex, testosterone was positively correlated with aggression and negatively correlated with pro-social personality. Structural equation modelling analyses suggested that a direct effect model best described the relationship between salivary testosterone and the latent personality dimensions of aggression and pro-social behavior. © 1996 Wiley-Liss, Inc.     

Role stressors and counterproductive work behavior: The role of negative affect and proactive personality

Based on the stressor‐emotion model, we propose that negative affect mediates the relationship between three role stressors (i.e., role ambiguity, role conflict, and role overload) and counterproductive work behavior (CWB), while proactive personality moderates the relationships between negative affect, role stressors, and CWB. We tested our hypotheses using data from 332 employees in Mainland China. We found that negative affect mediated the relationships between the three dimensions of role stressors and CWB. Role ambiguity was most strongly associated with CWB, followed by role conflict and then role overload. Proactive personality moderated the role ambiguity‐negative affect, role conflict‐negative affect, and negative affect‐CWB relationships, but not the relationship between role overload and negative affect.     

Cognitive competencies and aggressive behavior: A developmental study

A number of studies have demonstrated that increased socially related cognitive skills are associated with decreases in aggressive behavior. However, the link between aggression and intelligence or academic skills is less evident. While some research indicates that poor academic performance is related to aggression, it is unclear which components of intellectual ability and performance are critical to the management of aggressive behaviors. In two independent longitudinal studies of elementary school-age children, the relationship among several aspects of cognitive competence and several aspects of aggressive behavior were examined. The results of the first study showed that aggressive behavior observed in kindergarten children was more closely related to academic performance in the first and second grades than to general cognitive ability (IQ). The results of the second study, a comprehensive three-year investigation of upper elementary school-age children, indicated that teachers' assessments of aggression and parents' ratings of cruelty were consistent over time for boys, but not for girls. The intercorrelations among aggression measures within each of the three years also revealed stable sex differences. Boys identified as aggressive in the classroom were more likely to be perceived as aggressive, cruel, and/or delinquent at home, but for girls, there was little correlation between aggression at school and in the home. The analyses relating measures of cognitive functioning to indices of aggressive behavior made clear the importance of discriminating among various facets of these psychological constructs. IQ had a negligible relationship with aggression and a weak inverse relationship to delinquency. An overall index of cognitive functioning was a somewhat more consistent negative correlate of aggression, cruelty, and delinquency, especially for boys. A similar pattern was found for the correlates of academic performance. Academic disability was strongly related to delinquency in boys, and to a lesser degree to aggression in boys. Of the several cognitively related factors that were explored, Low Need Achievement manifested the strongest and most consistent relationships with the different facets of aggression and antisocial behavior, especially in boys. The implications of these results for psychological interventions in the school are discussed.     

The effect of fatigue driving on car following behavior

Existing fatigued driving analysis methods mainly focus on lateral driving performance by using the measurements related to the steering wheel or lane position. There is a lack of research on longitudinal car following behavior. In this study, 40 professional drivers are invited to participate in field expressway driving experiment, lasting at least for 6 h. During the test, their performance is measured in terms of their self-reported fatigued driving level according to the Karolinska Sleepiness Scale (KSS), the PERcentage of eye CLOSures (PERCLOS) and the Time Headway (THW). Then the effects of the fatigued driving level on car following behavior are evaluated. The results indicate that the fatigue level (for both KSS and PERCLOS) has significantly impact on THW parameters, including the mean, standard deviation and minimum THW. An increase in KSS and PERCLOS leads to a lower mean and minimum THW. Meanwhile, the standard deviation of THW increases with the increase of KSS and PERCLOS. In conclusion, this study found that a higher fatigue level leads to the driver keeping a smaller THW when following another vehicle and choosing shorter THW to make lane change. More deviation of car following performance was also found with the increase of fatigue level. Therefore, the findings of this study can be used to explain fatigue as one of the major reasons for rear-end collisions. Also, the research findings demonstrate the impact of fatigue on driving behavior in terms of car following performance, which can be used as a measurement for monitoring fatigued drivers.     

Y haplogroups and aggressive behavior in a Pakistani ethnic group

Studies show that personality dimensions such as aggression are influenced by genetic factors and that allelic variants located on the Y chromosome influence such behavior. We investigated polymorphisms on the male-specific region of the human Y chromosome in 156 unrelated males from the same ethnic background, who were administered the Punjabi translation of the Buss and Perry Aggression Questionnaire that measures four aspects that constitute aggressive behavior, i.e. physical aggression, verbal aggression, anger, and hostility. A value of .85 for Cronbach's coefficient alpha indicates considerable internal consistency and suggests that the psychometric properties of the aggression questionnaire can be adapted for the Pakistani population. A mean score+/-SD of 69.70+/-19.95 was obtained for the questionnaire. Each individual was genotyped following a phylogenetic hierarchical approach to define evolutionary Y haplogroups. Five Y haplogroups that are commonly found in Eurasia and Pakistan comprised 87% (n=136) of the population sample, with one haplogroup, R1a1, constituting 55% of the sampled population. A comparison of the total and four subscale mean scores across the five common Y haplogroups that were present at a frequency > or =3% in this ethnic group revealed no overall significant differences. However, effect-size comparisons allowed us to detect an association of the haplogroups R2 (Cohen's d statistic=.448-.732) and R1a1 (d=.107-.448) with lower self-reported aggression mean scores in this population.     

Assaultive behavior personality and personal space

Eysenck's Psychoticism, Extraversion and Neuroticism (PEN) Inventory was used to explore the role of personality variables in augmented personal space required by assaultive offenders. For both violent (n = 20) and nonviolent (n = 20) subjects personal space was greatest from a rear approach. Neither personality scores nor nature of offense alone predicted personal space needs; however personal space was significantly elevated in all directions for assaultive offenders with high scores on the psychoticism scale of the PEN Inventory.     

Adaptive and maladaptive personality traits as predictors of violent and nonviolent offending behavior in men and women

The aim of this study was to assess both violent and nonviolent offending behavior in a single, mixed‐sex population. The rationale for this is that the two types of offending are usually researched separately, despite evidence that they overlap. A comprehensive measure of general violence, intimate partner violence (IPV), and nonviolent offending behavior was administered to 116 men and 181 women, together with measures of personality and personality disorder (PD) traits, to investigate whether predictors of violent and nonviolent offending were similar or different for men and women. Men were found to perpetrate higher levels of general violence and nonviolent offenses than women, but women perpetrated significantly more IPV than men. Cluster B PD traits predicted all three offense types for women and also men's general violence and nonviolent offending. Women's general violence and men's non‐violence also had one unique risk factor each, low agreeableness, and low conscientiousness, respectively. The main difference was for IPV, where men's IPV was predicted by cluster A PD traits, indicating that men's and women's risk factors for IPV may be different, although their risk factors for the other offense types were fairly consistent.

Predicting counterproductive work behavior from the interaction of personality traits

Much attention has been given to enhancing the prediction of counterproductive work behavior (CWB), with a particular focus on the relationship between the five factor model of personality and CWB. Several scholars have advocated for a more complex view of this relationship, and rather than focusing simply on main effects, to examine the interaction of personality traits in predicting employee behavior. In consideration of the traits most strongly related to CWB, we examined the interaction between: (1) conscientiousness and emotional stability, (2) agreeableness and emotional stability, and (3) conscientiousness and agreeableness on CWB directed at individuals (CWB-I) and the organization (CWB-O). Results from a multi-national sample illustrate the interaction of traits increases the prediction of CWB over and above a single trait approach. The interactions suggest employees perform the least CWB when they are high on both traits (in the respective trait pairings), but low levels on either trait relate to increased CWB, and at levels comparable to individuals low on both traits. We conclude research on personality and CWB would benefit from an interactive approach as it allows for greater prediction of CWB-O and CWB-I, which is important in light of the organizational and interpersonal consequences of employee misbehavior.     

Experimentally manipulated change in children's proactive and reactive aggressive behavior

The current study assessed the effectiveness of two behavior manipulations created to differentially lower aggressive responses in a laboratory task. It was hypothesized that the reactive anger manipulation would have the greatest effect for reactive aggressive behavior and the instrumental manipulation would significantly affect proactive aggressive behavior and slightly affect the reactive behavior. Fifty participants played pinball in competition for points against an unknown peer, whose responses were actually controlled by the experimenter. Participants could push a noise button, sending the peer an annoying noise; a tilt button, interfering with the opponent's game; or a no answer button, offering a pro‐social alternative to aggression. After playing four rounds, participants were randomly assigned to either a reactive anger or a positive instrumental manipulation group; they then played pinball again for four rounds. Results indicate that the instrumental manipulation significantly lowered aggressive responses for both reactive and proactive behavior. The reactive manipulation effected aggressive responses only for use of the noise button and produced significantly lower levels of anger. Aggr. Behav. 29:215–227, 2003. © 2003 Wiley‐Liss, Inc.
