Predictors of demand for risk mitigation in transport

The core aim of the present study is to examine the associations between risk awareness, risk perception, worry and risk tolerance on the one hand and priority of safety and demand for risk mitigation in transport on the other hand. The results are based on a self-completion questionnaire survey carried out in a randomly selected representative sample of the Norwegian public obtained from the Norwegian population registry during the autumn and winter 2004 (n = 510). The response rate was 51% and comparisons with general population statistics showed that the sample was adequately representative of the Norwegian population in regard of gender, age, education and previous injury experience. Three variables (risk awareness, worry and priority of safety) were significant predictors of demand for risk mitigation. There was also a negative association between worry and risk tolerance. Contrary to previous research on risk perception, the present study did not find support for the hypothesis that general risk perception was a significant predictor, neither of priority of safety, nor of demand for risk mitigation. However, as expected perceived risk was strongly associated with the respondents’ worry. Worry was a significant predictor of priority of safety as well as for demands for risk mitigation. Personal worry did not have the same effect on demand for risk mitigation as general worry.     

A meta-analysis of the association between forgiveness of others and physical health

Objective: This meta-analysis tested the relation between forgiveness of others and physical health (PH) with age, gender, race, education level, employment status, sample type, research design, type of PH variables, and publication status as the potential moderators.

Design: Eligible studies had participants with or without physical or mental health problems and had quantitative data on forgiveness of others and PH. The random-effects model was used to aggregate Fisher’s z effect sizes, which were converted back to correlation coefficients.

Main Outcome Measures: State forgiveness (forgiving an offense or offender) measures, trait forgiveness (a disposition to forgive) measures and physical health measures were included in the meta-analysis.

Results: A hundred and twenty-eight studies (N?=?58,531) were retrieved, in which the mean effect sizes showed a significant positive relationship between forgiveness of others and PH (r?=?0.14, p?<?0.001, 95% CI [0.11, 0.17]). Further, no moderators showed a significant relation between forgiveness of others and PH.

Conclusions: The positive relation between forgiveness of others and PH was not affected by potential moderators. Because the results are correlational, more forgiveness interventions may be needed to examine the causal effect of the relation between forgiveness of others and PH.     

A longitudinal study on the relationship between adolescents’ medical drama viewing and speeding

The present study aimed to examine whether watching medical drama had a long-term protective effect on speeding behavior. Specifically, this research examined the extent to which medical drama viewing in adolescence predicts risk perceptions, crash fear, speeding attitudes and self-reported speeding behavior in early adulthood. Using a longitudinal research method, 487 adolescents (M_age = 17.7 at baseline) who responded to an earlier survey were re-interviewed five years later. Structural equation modeling indicated that more medical drama viewing at baseline was associated with increased risk perception and higher driving-related fear five years later. The fear of being involved in a traffic crash appeared to be associated with less favorable attitudes toward speeding. Furthermore, in line with the expectations, these speeding attitudes were a significant predictor of self-reported speeding behavior. These results help to provide a better understanding of the relationship between media use and subsequent risk-taking, and have implications for prevention efforts.     

Using an integrated simulation environment for the risk based design of advanced driver assistance systems

When designing new Advanced Driver Assistance Systems (ADAS), the existing guidelines like the RESPONSE 3 Code of Practice imply intense testing of the system prior series production. Within the EU-FP7-Project ISi-PADAS a new methodology of risk based design has been established which includes an integrated simulation platform. This integration enables intense testing of new prototypes in an accelerated way and therefore enhances the design process while directly combining the simulation results with a risk matrix.This paper describes the new methodology while focussing on the software framework and the procedure of risk assessment in detail. It shows the general approach as well as the appropriate steps taken for an ADAS prototype developed in the context of ISi-PADAS.     

Big Five personality traits and allostatic load in midlife

Objective: To examine the cross-sectional associations of Big Five personality traits with midlife allostatic load, including the role of sex, socio-demographic factors and health-related behaviours.

Design: Cross-sectional analyses of 5512 members of the Copenhagen Aging and Midlife Biobank, aged 49–63 years, 69% men.

Main outcome measure: Allostatic load (AL) based on 14 biomarkers representing the inflammatory, cardiovascular and metabolic system.

Results: Due to significant sex?×?trait interactions, analyses were stratified by sex. Openness and Conscientiousness were inversely associated with AL in both sexes, and Extraversion was positively associated with AL in men. Adjusting for socio-demographic factors significantly attenuated the association of Openness in both sexes and of Extraversion in men, for whom the inverse association of Agreeableness with AL was strengthened. Further adjusting for health-related behaviours, the Conscientiousness-AL association was attenuated but remained significant, and Agreeableness remained significantly associated with AL in men.

Conclusion: Results imply that higher levels of Agreeableness (in men) and Conscientiousness are associated with lower levels of AL above and beyond socio-demographic factors and health-related behaviours. The study further contributes by demonstrating the relevance of sex?×?trait and trait?×?trait interactions in the personality-health literature.     

Psychometric properties and factor analyses of the achievement motivation measure

ABSTRACT

The purpose of this study was to develop a theoretically-driven instrument of achievement motivation and determine its validation. The Achievement Motivation Measure (AMM) is closely aligned with Atkinson and McClelland's (1948, 1953, 1961) theoretical constructs of achievement thoughts and behaviours. Confirmatory and exploratory factor analysis (CFA and EFA) methods evaluated the structural validity of a newly developed instrument, the AMM, by assessing achievement thoughts and behaviours. Participants included 632 graduate and undergraduate university students. EFA supported two factors (Achievement Thoughts and Achievement Behaviours) with 13 items. Findings of a CFA supported the modified two-factor model as fitting the data. The theoretically supported AMM effectively measured achievement motivation by assessing achievement thoughts and behaviours.     

Trajectories of public psycho-behavioural responses relating to influenza A(H7N9) over the winter of 2014-15 in Hong Kong

Objective: To explore trajectories of public psycho-behavioural responses over one influenza A(H7N9) epidemic wave, and examine the interplays among social norm influence, disease worry and protective behaviours.

Methods: Participants were 464 adults who completed the baseline and at least two follow-up assessments on their H7N9-related Perceived Susceptibility, Perceived Severity, Perceived Efficacy, Worry, Social Norms influence and Protective Behaviours in a five-phase longitudinal survey over one H7N9 epidemic wave. Latent growth modelling (LGM) identified trajectories of these psycho-behavioural responses while multi-process LGM examined the inter-relationships among trajectories of Social Norms influence, Worry and Protective Behaviours.

Results: Trajectories of Perceived Susceptibility, Worry, Social Norms and Protective Behaviours increased initially but declined as the epidemic decayed, while Perceived Severity increased linearly and Perceived Efficacy remained stable across the epidemic. Change in Social Norms influence was significantly associated with change in Worry (β?=?0.65) which was significantly associated with change in Protective Behaviours (β?=?0.62).

Conclusion: The public’s threat appraisal but not efficacy appraisal may have been well-informed by epidemic-related information. Social Norms may be important contributors of public emotional response to an epidemic. Communication via social networks during an epidemic could be important for regulating public emotional response and guiding their behavioural change.     

One-year test–retest reliability of the Maryland Resource for the Behavioral Utilization of the Reinforcement of Negative Stimuli (MRBURNS)

The Maryland Resource for the Behavioral Utilization of the Reinforcement of Negative Stimuli (MRBURNS) is a novel behavioral task designed to measure individual differences in negative reinforcement-based risk taking propensity. Performance on the MRBURNS has been linked with alcohol-related problems and negative reinforcement-based drinking motives, as well as symptoms of anxiety and depression; however, it is unclear if performance on the task represents a stable measure of negative reinforcement-based risk taking over time. As such, the current study aimed to examine the test–retest reliability of the MRBURNS over a period of one year. Results indicate that the correlation between year 1 and year 2 risk behavior (average number of pumps) on the MRBURNS was .43 across all trials. With the one year test–retest reliability of the MRBURNS established, the MRBURNS may be a useful approach to measuring the relative contribution of negative reinforcement-based risk taking in the development of risky behaviors over time, and may be used to monitor the effects of novel interventions that aim to reduce negative reinforcement based risk taking in the real world.
