Risky attitudes towards road use in pre-drivers

Motor vehicle accidents are one of the principal causes of adolescent disability or mortality and male drivers are more likely to be involved in road accidents than female drivers. In part such associations between driver age and sex have been linked to differences in risky behaviour (e.g. speed, violations) and individual characteristics (e.g. sensation seeking, deviant behaviour). The aim of this research is to determine whether associations between risky road user behaviour and individual characteristics are a function of driver behaviour or whether they are intrinsic and measurable in individuals too young to drive. Five hundred and sixty-seven pre-driver students aged 11-16 from three secondary schools completed questionnaires measuring enthusiasm for speed, sensation seeking, deviant behaviour and attitudes towards driver violations. Boys reported more risky attitudes than girls for all measures. Associations between sensation seeking, deviant behaviour and attitudes towards risky road use were present from early adolescence and were strongest around age 14, before individuals learn to drive. Risky attitudes towards road use are associated with individual characteristics and are observed in adolescents long before they learn to drive. Safe attitudes towards road use and driver behaviour should be promoted from childhood in order to be effective. (C) 2007 Elsevier Ltd. All rights reserved.

A behavioral comparison between motorcyclists and a matched group of non-motorcycling car drivers: factors influencing accident risk

Motorcyclists and a matched group of non-motorcycling car drivers were assessed on behavioral measures known to relate to accident involvement. Using a range of laboratory measures, we found that motorcyclists chose faster speeds than the car drivers, overtook more, and pulled into smaller gaps in traffic, though they did not travel any closer to the vehicle in front. The speed and following distance findings were replicated by two further studies involving unobtrusive roadside observation. We suggest that the increased risk-taking behavior of motorcyclists was only likely to account for a small proportion of the difference in accident risk between motorcyclists and car drivers. A second group of motorcyclists was asked to complete the simulator tests as if driving a car. They did not differ from the non-motorcycling car drivers on the risk-taking measures but were better at hazard perception. There were also no differences for sensation seeking, mild social deviance, and attitudes to riding/driving, indicating that the risk-taking tendencies of motorcyclists did not transfer beyond motorcycling, while their hazard perception skill did.

Samband mellan personlighet och yrkesval

Är poliser mer spänningssökande än andra? Det är frågan som ligger till grund för studien där syftet är att jämföra poliser med lärare i vilken utsträckning de söker spänning. Studien genomfördes med hjälp av ett frågeformulär bestående av 28 påståenden som kommer ifrån redan vedertagna skalor. Dessa är Eysenck Personality Inventory och Zuckerman’s Sensation Seeking Scale. 62 personer deltog i studienvarav hälften var lärare och hälften poliser. Poliserna fick signifikant högre poäng än lärarna på de påståenden som handlade om att ta risker och fatta snabba beslut. Lärarna fick i sin tur signifikant högre poäng på de påståenden som handlar om impulsivitet gällande resor. Den slutsats man kan dra av denna studie är att poliser söker sig till arbeten som i sig innebär mer spänning medan lärare i större utsträckning söker spänning utanför arbetet.

Personality and responses to appetitive and aversive stimuli: the joint influence of behavioural approach and behavioural inhibition systems

Gray’s reinforcement sensitivity theory (RST) posits two separable neurological systems involved in the regulation of personality and behaviour. The behavioural approach and inhibition systems facilitate the expression of appetitive (impulsive-sensation seeking traits) and aversive motivation (anxiety traits), respectively. Inconsistent findings regarding associations between measures of personality and behavioural responses to appetitive and aversive stimuli has led to a modification of RST including the notion that, rather than separable as first hypothesised, the two systems jointly influence behaviour. The current study was designed to investigate this proposal with an additional focus on the role of reinforcement expectancies. Seventy-eight participants completed two questionnaire measures of BIS/BAS activity (EPQ-R, SPSRQ) and two behavioural measures (Q-TASK, Card Arranging Reward Responsivity Objective Task). Findings were in general consistent with the original separable systems approach, however they also showed that aversive responses were highest in high BAS/high BIS individuals, thus suggesting an interactive account of BIS/BAS processes. Further, stronger positive correlations between self-report BAS traits and behavioural reward responsiveness were found for participants who perceived the task as more rewarding than initially expected. Discussion focuses on the role of reward expectancies and on the issue regarding separable vs. joint BIS/BAS systems.

Reactivity to alcohol-related cues: relationship among cue type, motivational processes, and personality

This study examined the relationship between personality traits implicated in the drinking literature (i.e., sensation seeking and anxiety) and reactivity to 2 different alcohol cues. The opportunity to consume alcohol was manipulated, and differences in urge and affective reactivity were assessed. Gray’s (1987) model of impulsive sensation seeking and anxiety was adopted to investigate relationships between personality and responses to the appetitive (consumption) and aversive (no consumption, nonrewarding) alcohol cues in 40 regular social drinkers. The consumption cue produced increases in appetitive motivation and positive correlations with sensation-seeking traits. The no-consumption cue produced increases in aversive motivation and positive correlations with anxiety-related traits. It was concluded that Gray’s model of impulsive sensation seeking and anxiety may provide a useful framework for examining the personality correlates of cue reactivity to different cues.

Should personality traits be considered when refining substance misuse treatment programs?

The interplay between stable personality characteristics and environmental factors is emphasised in most contemporary approaches to individual differences. This interaction appears to be important in understanding the development of substance use and misuse. Impulsivity related personality traits such as sensation-seeking, novelty seeking, reward-sensitivity and behavioural disinhibition, are strongly linked to adolescent and adult substance use and misuse. The role of anxiety-related traits, in the development of substance misuse is less clear. Nonetheless, anxiety disorders are very common amongst adult substance misusers and almost certainly play a critical role in the maintenance of a substance use disorder and influence treatment effectiveness. The data suggest that personality influences treatment outcomes and yet these individual differences are generally not addressed in treatment. We argue in this review that interventions which are matched to these relevant personality traits may improve treatment outcomes for substance misusers. [Staiger PK, Kambouropoulos N, Dawe S.

A cross-national comparison of risk and protective factors for adolescent substance use : the United States and Australia

Purpose
To compare risk and protective factors that influence youth substance use in Australia and the United States. The two countries have different policy orientations toward substance use: Australia has adopted harm-reduction policies, and the United States has adopted abstinence-focused polices.

Methods
Cross-sectional survey data were collected from independent samples of adolescents in the states of Maine (N = 16,861; 53% female, 7% Non-white) and Oregon (N = 15,542; 51% female, 24% Non-white) in the United States and Victoria in Australia (N = 8442; 54% Female, 11% Non-white) in 1998 (Maine and Oregon) and 1999 (Victoria). Chi-square tests, t-tests, effect size comparisons, and logistic regression analyses that accounted for age and gender were used to investigate cross-national similarities and differences in: (a) rates of cigarette, alcohol, and marijuana use; (b) levels of risk and protective factors; and (c) magnitudes of associations between risk and protective factors and substance use.

Results
More adolescents in Victoria reported using cigarettes and alcohol, whereas more of the U.S. adolescents reported using marijuana. Exposure to risk and protective factors was generally similar in the cross-national samples. However, adolescents in Maine and Oregon perceived handguns to be more readily available, reported more participation in religious activities, and were higher in sensation-seeking and social skills; and adolescents in Victoria had more favorable attitudes toward drug use and reported community norms and parental attitudes more favorable to drug use. Most of the risk and protective factors were strongly associated with substance use to a similar degree in Victoria, Maine, and Oregon. However, among adolescents in Maine and Oregon peer/individual risk and protective factors associated with social detachment were more strongly related to substance use, and among adolescents in Victoria, family protective factors were less strongly related to alcohol use.

Conclusions
Inter-country influences on youth substance use are generally similar despite different policy directions. Existing differences suggest that the abstinence policy context is associated with higher levels of illicit drug use and stronger relations between individual indicators of social detachment and substance use, whereas the harm reduction policy context is related to more cigarette and alcohol use, possibly from exposure to normative influences that are more tolerant of youth drug use.

Family relationship quality and early alcohol use : evidence for gender-specific risk processes

Objective: Family characteristics (relationship quality, parental behaviors, and attitudes relating to alcohol use) are known to influence alcohol use in the mid-teen years, and there is evidence that family characteristics have different influences on mid-teen girls versus boys. This study examined child gender differences in the association of family relationship quality, parental disapproval of children's alcohol use, and parental alcohol use with early adolescent alcohol use.

Method: Grade 6 and 8 students (modal age 11 and 13, respectively; N = 6,837; 52.6% female) were recruited from 231 schools across three Australian states. Hypotheses were tested using two-level ordinal logistic regression (individuals nested within schools). The main dependent measure was lifetime frequency of early adolescent alcohol consumption. Independent variables included mother's/father's alcohol use, closeness, conflict, and disapproval of adolescent alcohol use. Control variables included sensation seeking, peer alcohol use, and socioeconomic disadvantage.

Results: The key findings were that for the young age group (Grade 6), emotional closeness to the parent of the opposite sex was protective. Family conflict was associated with females' drinking in both age groups but not males' drinking.

Conclusions: There was evidence of gender differences in the epidemiology of family relationship quality and early alcohol use. Social developmental models may need revision to account for these child gender differences. Gender-specific family dynamics may be an important consideration for family-oriented prevention strategy.

The influence of parents, siblings and peers on pre- and early-teen smoking : a multilevel model

Introduction and Aims. Despite considerable success in tobacco control, many teenagers in Australia and other industrialised countries still smoke tobacco. There is mixed evidence on the relative influence of proximal social networks (parents/siblings/peers) on pre- and early-teen smoking, and no research has examined how these influences compare after accounting for school- and community-level effects.The aim of this study was to compare the relative influences of parents, siblings and peers, after accounting for school- and community-level variation in smoking.

Design and Methods. A cross-sectional fixed and random effects model of smoking prevalence was used, with individuals (n = 7314) nested within schools (n = 231) nested within communities (n = 30). Grade 6 and 8 students (modal ages 11 and 13 years) completed an on-line survey. Key variables included parent/sibling/peer use. Controls included alcohol involvement, sensation seeking, pro-social beliefs, laws/norms about substance use and school commitment.

Results.There was significant variation in smoking at both the school and community levels, supporting the need for a multilevel model. Individual-level predictors accounted for much of the variance at higher levels. The strongest effects were for number of friends who smoke, sibling smoking and alcohol involvement. Smaller significant effects were found for parent smoking. At the community level, socioeconomic disadvantage was significant, but community-level variance in pro-social and drug-related laws/norms was not related to smoking.

Discussion and Conclusions. Cross-level interactions were generally non-significant. Early teenage smoking was best explained by sibling and peer smoking, and individual risks largely accounted for the substantial variation observed across schools and communities. In terms of future tobacco control, findings point to the utility of targeting families in disadvantaged communities.[Kelly AB, O'Flaherty M, Connor JP, Homel R, Toumbourou JW, Patton GC, Williams J.

Predictors and responses to the growth in physical violence during adolescence : a comparison of students in Washington State and Victoria, Australia

This study investigates patterns in violence over 3 time points in early to midadolescence in 2 statewide representative samples of youth, one in Washington State, USA, and the other in Victoria, Australia. Comparable data collection methods in both states were used to cross-nationally compare patterns of violence, risk factors, and responses to violence (school suspensions and arrests) in 2 policy contexts. Risk factors include early use of alcohol, binge drinking, involvement with antisocial peers, family conflict, poor family management, sensation seeking, and bully victimization. These are modeled as correlates of initial violence and predictors of change in violence over a 3-year period, from ages 12–15, for participating youth. Results suggest that patterns and predictors of violence are mostly similar in the 2 states. Initial levels of violence (age 13) and change over time in violence were associated in both states with more youth school suspensions and more police arrests in Grade 9. Some cross-national differences were also shown. For example, correlations of violence with gender and violence with binge drinking were stronger in Victoria, whereas correlations of violence with early use of alcohol and with antisocial peer involvement were stronger in Washington State. Antisocial peer involvement and family conflict were significant predictors of a gradual increase in violence from Grades 7–9 for youth in Victoria only. Implications are discussed with attention to prevention and intervention efforts.

The influence of families on early adolescent school connectedness : evidence that this association varies with adolescent involvement in peer drinking networks

School connectedness is central to the long term well-being of adolescents, and high quality parent–child relationships facilitate school connectedness. This study examined the extent to which family relationship quality is associated with the school connectedness of pre- and early teenagers, and how this association varies with adolescent involvement in peer drinking networks. The sample consisted of 7,372 10–14 year olds recruited from 231 schools in 30 Australian communities. Participants completed the Communities that Care youth survey. A multi-level model of school connectedness was used, with a random term for school-level variation. Key independent variables included family relationship quality, peer drinking networks, and school grade. Control variables included child gender, sensation seeking, depression, child alcohol use, parent education, and language spoken at home. For grade 6 students, the association of family relationship quality and school connectedness was lower when peer drinking networks were present, and this effect was nonsignificant for older (grade 8) students. Post hoc analyses indicated that the effect for family relationship quality on school connectedness was nonsignificant when adolescents in grade 6 reported that the majority of friends consumed alcohol. The results point to the importance of family-school partnerships in early intervention and prevention.

Modifying the risk associated with an impulsive temperament: a prospective study of drug dependence treatment

The evidence linking the personality trait of impulsivity and substance misuse is well established. Importantly, impulsivity not only predicts substance misuse problems but has an association with duration in treatment, likelihood of completing treatment and time to relapse. Treatment that focuses on increasing awareness and acceptance of thoughts and emotions may potentially address impulsive behaviour and in this respect improve treatment outcomes for substance misuse. The current paper investigated the relationship between the facet of impulsivity that taps into poor inhibitory control and treatment outcome. In addition, there was a specific focus on ascertaining the impact of an increase in awareness and attentional control measured in 144 adult substance users receiving treatment in a residential therapeutic community. Impulsivity predicted poorer treatment outcome (measured as drug use severity). Increases in awareness and acceptance of emotions and thoughts during treatment were related to better outcome although this was not associated with baseline levels of impulsivity. Clinical and theoretical implications are discussed.

The influence of protective and risk factors in individual, peer and school domains on Thai adolescents' alcohol and illicit drug use: a survey

This study investigates risk and protective factors for substance abuse in a sample of 1778 students attending technical colleges in Bangkok and Nakhon Ratchasima provinces of Thailand using a self-report questionnaire modified from the Communities That Care youth survey. Low school commitment was strongly associated with illicit drug use, with adjusted odds ratios ranging from 2.84 (glue sniffing) to 10.06 (ecstasy). Having friends using drugs, and friends with delinquent behaviors increased the risk of using alcohol and illegal drugs, with adjusted odds ratios of 6.84 and 6.72 respectively for marijuana use. For protective factors, approximately 40-60% of students with high levels of moral belief, participation in religious activities, and social skills were less likely to use alcohol. It is concluded that peer influence is a significant contributor to Thai adolescents' participation in substance abuse and that engaging in religiosity may assist adolescents to internalize negative aspects of harmful drugs into positive perceptions and encourage them to avoid alcohol and illegal drugs.

Risky driving in young adults : A review of the literature

Young drivers aged between 16 and 25 are consistently over-represented in fatal crash statistics and are more likely than older drivers to be involved in a range of intentional risky driving behaviours, such as drink driving, speeding, drag racing, and tailgating. This paper reports the fndings of a systematic search of published peer-reviewed literature, identifying the association between age and the characteristics of risky drivers, as well as interventions that have been developed to improve their safety. The results suggest that it is young males who are predominantly involved in unsafe driving and that these drivers are generally high in reward sensitivity, have antisocial peers, and believe that they are not dangerous drivers. Further to this, deterrence-based interventions have shown limited efectiveness for the specifc category of 'hoon' drivers, suggesting the need for targeted interventions across a multitude of domains. Efective intervention requires an understanding of the antecedents of dangerous driving behaviour, and it is concluded that interventions might be most efective when targeted towards these identifed criminogenic needs.
