The Difference

We developed a visual tool to assess risk perception for a sample of male construction workers (forty Italian and twenty-eight immigrant workers), just before and after a sixteen-hour training course. The questionnaire included photographs of real construction sites, and workers were instructed to select pictograms representing the occupational risks present in each photograph. Points were awarded for correctly identifying any risks that were present, and points were deducted for failing to identify risks that were present or identifying risks that were not present. We found: (1) Before the course, risk perception was significantly lower in immigrants compared to Italians ( p < .001); (2) risk perception improved significantly ( p < .001) among all workers tested; and (3) after the training, the difference in risk perception between Italians and immigrants was no longer statistically significant ( p = .1086). Although the sample size was relatively small, the results suggest that the training is effective and may reduce the degree to which cultural and linguistic barriers hinder risk perception. Moreover, the use of images and pictograms instead of words to evaluate risk perception could also be applied to nonconstruction workplaces.

Risk perception refers to how individuals interpret their susceptibility to threats, and has been hypothesised as an important predictor of intentions and behaviour in many theories of health behaviour change. However, its components, optimal measurement, and effects are not yet fully understood. The TRIRISK model, developed in the US, conceptualises risk perception as deliberative, affective and experiential components. In this study, we aimed to assess the replicability of the TRIRISK model in a UK sample by confirmatory factor analysis (CFA), explore the inherent factor structure of risk perception in the UK sample by exploratory factor analysis (EFA), and assess the associations of EFA-based factors with intentions to change behaviour and subsequent behaviour change. Data were derived from an online randomised controlled trial assessing cancer risk perception using the TRIRISK instrument and intention and lifestyle measures before and after communication of cancer risk. In the CFA analysis, the TRIRISK model of risk perception did not provide a good fit for the UK data. A revised model developed using EFA consisted of two separate “numerical” and “self-reflective” factors of deliberative risk perception, and a third factor combining affective with a subset of experiential items. This model provided a better fit to the data when cross-validated. Using multivariable regression analysis, we found that the self-reflective and affective-experiential factors of the model identified in this study were reliable predictors of intentions to prevent cancer. There were no associations of any of the risk perception factors with behaviour change. This study confirms that risk perception is clearly a multidimensional construct, having identified self-reflective risk perception as a new distinct component with predictive validity for intention. Furthermore, we highlight the practical implications of our findings for the design of interventions incorporating risk perception aimed at behaviour change in the context of cancer prevention.

Abstract Background Travellers’ risk perception is a key component of travel risk assessment because it influences the adequate implementation of safety precautions. The aims of this study are to validate a tool to analyse travellers’ risk perception to identify which factors can influence it and how it changes upon return. Methods The Traveller’s Risk Perception (TRiP) questionnaire was developed and administered to outpatients before and after travel in three travel clinics. A principal component analysis (PCA) was performed to validate the questionnaire and multivariate regression analysis was used to evaluate the effect of travellers’ characteristics on the risk scores. Results A total of 1020 travellers completed the questionnaire. PCA identified two latent factors: ‘generic-disseminated risks’ and ‘specific-circumstantial risks’. Cronbach’s α was acceptable (0.76 and 0.70, respectively). The ‘generic-disseminated risks’ dimension scored higher than the ‘specific-circumstantial risks’ (p&lt;0.001). The items with the highest scores were insect bites, gastrointestinal disorders and malaria. The mean scores were significantly lower after the travel for all items but one. Conclusions The TRiP questionnaire is a valid and reliable tool for rating travellers’ perceptions. Staff in travel clinics should be trained to systematically assess travellers’ risk perception in order to tailor the consultation according to specific information needs.

Abstract. Resilience has rapidly arisen in multiple disciplines and has been regarded as the key in disaster mitigation and adaptation. Objective indicator framework is a common way evaluating resilience while limited attention on measuring subjective resilience. In fact, subjective resilience might further explain how people respond to the uncertainty of disaster risks. Due to the limitation on predicting potential earthquake events, past studies put more efforts on discussing pre-disaster. Luckily, this paper could explore the change of risk perception and adaptation behavior in types of socio-economic groups through a comparative analysis between pre- and post- earthquake disaster, and one-way analysis of variance with Post Hoc test is applied to examining the change of risk perception and adaptation behavior. The results show that female might be much willing on house retrofit due to the fear and the worrisome. However, the elders might be less aware on earthquake than the young. Education indeed affects people’s risk perception and adaptive behavior. As a whole, the results could be referred to areas clustered of male, female, elder population, and lower education population by providing risk communication, risk education, and diverse disaster adaptation options. Although limitation exists, the results of comparative analysis between pre-disaster and post-disaster conditions could be referred to adequate strategies and decide the priority of risk management policies by governments.

Purpose – Attempting to explore the role of direct experience in influencing disaster consciousness and public opinion, the purpose of this paper is to carry out comparative analyses of Japanese people’s knowledge, risk perception, and policy preference about large-scale earthquake disaster before and after the Great East Japan Earthquake. More importantly, aiming to provide implications regarding the application of past experience, the predictive power of direct experience on disaster consciousness is also examined. Design/methodology/approach – This study analyzed parts of the data collected from two nationwide public opinion surveys among Japanese conducted by the Japanese Government. Analyses of variance were performed to examine changes in disaster consciousness. A path model was developed to examine the predicted effects of direct experience. χ2 tests were performed to examine changes in strategy preference. Findings – This study found significant changes in Japanese people’s knowledge of natural hazards and perception of mega disaster risk. Tests of the path model suggested significant positive effect of societal level impact on disaster consciousness and strong predictive power of knowledge on risk perception. Significant changes in strategy preference were also found. Practical implications – Results supported the predictive power of direct experience, highlighting the significance of recalling past experience as well as creating indirect experience to raise public consciousness and motivate appropriate actions. Originality/value – This is one of the few studies that investigate changes in public opinion among Japanese before and after the Great East Japan Earthquake.

Accident Scenarios

Research in the area of risk perception has shown that people consistently underestimate common risks and overestimate rare ones. This tendency could have an undesirable effect on behavior in potentially hazardous situations. An imaging method was employed for the purpose of changing the perceived risk of a group of potential hazards. The hazards were coffee maker, lawn mower, pesticide, bicycle, power saw, toaster, asbestos, and swimming pool. Subjects sketched cartoons or scenarios of themselves having an accident involving each of a subgroup of the hazards. Subjects rated the risk of each hazard to themselves and estimated injury frequencies for the general population both before and after they sketched the accident scenario. They also rated the hazards on a variety of dimensions such as severity, plausibility, familiarity, imageability, etc. The results indicate that certain characteristics of the hazard determine how likely the risk perception is to change when accident scenarios are made cognitively available.
