Risk perceptions and trust following the 2010 and 2011 Icelandic volcanic ash crises.

Eruptions at the Icelandic volcanoes of Eyjafjallajökull (2010) and Grimsvötn (2011) produced plumes of ash posing hazards to air traffic over northern Europe. In imposing restrictions on air traffic, regulators needed to balance the dangers of accidents or aircraft damage against the cost and inconvenience to travelers and industry. Two surveys examined how members of the public viewed the necessity of the imposed restrictions and their trust in different agencies as estimators of the level of risk. Study 1 was conducted with 213 British citizens (112 males, 101 females), who completed questionnaires while waiting for flights at London City Airport during May 2012. Study 2 involved an online survey of 301 Icelandic citizens (172 males, 127 females, 2 undeclared gender) during April 2012. In both samples, there was general support for the air traffic restrictions, especially among those who gave higher estimates of the likelihood of an air accident or mishap having otherwise happened. However, in both countries, the (minority of) respondents who had personally experienced travel disruption were less convinced that these restrictions were all necessary. Scientists, the International Civil Aviation Organization, and (in Iceland) the Icelandic Department of Civil Protection were all highly trusted, and seen as erring on the side of caution in their risk estimates. Airlines were seen as more likely to underestimate any risk. We conclude that perceptions of the balance between risk and caution in judgments under uncertainty are influenced by one's own motives and those attributed to others.

Smokers' compliance with smoke-free policies, and non-smokers' assertiveness for smoke-free air in the workplace: a study from the Balkans.

OBJECTIVE: Identify the psychosocial variables that predict smokers' compliance with smoke-free policies at work, and non-smokers' assertiveness for smoke-free rights in Greek and Bulgarian workplaces. METHODS: Data were collected from employees in Greece and Bulgaria. The main outcome measures were smokers' compliance with smoke-free policies, and non-smokers' assertiveness intentions. Demographic variables, tobacco use and dependence, as well as beliefs about second-hand smoke (SHS) exposure and smoking at work were also assessed. RESULTS: Regression analyses showed that smokers' compliance with smoke-free policies was predicted by age, perceived health risks of smoking, and beliefs related to the benefits of smoking at work. Non-smokers' assertiveness was predicted by annoyance from exposure to SHS at work, and assertiveness-related social cognitions (e.g., attitudes, social norms, and self-efficacy). CONCLUSIONS: Interventions to promote support for tobacco control policies at work in Greece and Bulgaria may benefit from targeting smokers' beliefs about the actual effects of tobacco use on health and job performance. Accordingly, efforts to promote non-smokers assertiveness should build stronger assertiveness-related attitudes, convey anti-smoking normative messages, and strengthen self-efficacy skills.

Social cognitive predictors of smoking cessation intentions among smoker employees: the roles of anticipated regret and social norms.

The present study assessed the effects of anticipated regret, social norms, and related social cognitions on smoking cessation intentions among indoor employees in a pro-smoking culture. Overall, 93 daily smokers completed anonymous structured questionnaires assessing attitudinal and health beliefs about tobacco use, social norms, quitting self-efficacy, and anticipated regret. Past quit attempts and tobacco dependence were also measured. Hierarchical linear regression and mediation analyses showed that attitudes toward quitting, self-efficacy and anticipated regret significantly predicted cessation intentions, over and above past quit attempts and tobacco dependence. Unlike in previous studies, tobacco dependence, descriptive norms and smoke-free policies did not directly influence quit intentions in our sample of smokers. Anticipated regret mediated the effects of attitudes and social norms on cessation intentions.

Adolescents' support for smoke-free public settings: the roles of social norms and beliefs about exposure to secondhand smoke.

PURPOSE: To assess support for smoke-free policies in public settings among adolescent smokers and nonsmokers in a pro-smoking culture. METHODS: A total of 1,924 Greek secondary school students (mean age = 14 years, standard deviation = 1.00, 50% female) from nine schools in the urban area of Thessaloniki, Greece, participated in the study. The main outcome measures were supportiveness of smoke-free policies in public settings. RESULTS: Smoker adolescents were less supportive of smoke-free policies, compared with nonsmokers. Regression analysis showed that policy support was predicted by smoking status and motivation to smoke, social norms, and beliefs about the effects of smoking and exposure to secondhand smoke. A significant interaction between smoking status and social norms was also observed, as smoker adolescents who often encountered others smoking in public places reported less support for smoke-free public settings. CONCLUSIONS: Three important processes underlying adolescents' support for smoke-free policies not mentioned in previous research were identified. First, social norms of the immediate social environment play a pivotal role in shaping policy support of young people. Second, the effects of smoking status on policy support are significantly moderated by exposure to public smoking. Finally, beliefs about the effects of exposure to secondhand smoke significantly predict young people's support for smoke-free public settings.

Associations between authoritative parenting and the sun exposure and sun protective behaviours of adolescents and their friends.

Associations between the sun exposure and sun protective behaviours of adolescents and their friends were examined along with the role played by authoritative parenting and other family and peer socialisation factors. Four hundred and two adolescents (198 males, 204 females) participated in the research. It was found that these adolescents and their friends shared similar sun exposure and sun protective behaviours and had similar parenting backgrounds. Parental authoritativeness was positively associated with the use of sun protection, even after the effects of other familial and peer variables were controlled, but not with the time spent sunbathing which was associated with friends' behaviours. The theoretical and practical implications of these findings are discussed.

Can you please put it out? Predicting non-smokers' assertiveness intentions at work.

OBJECTIVE: The present study aimed to identify the psychosocial predictors of non-smoker employee intentions to ask smokers not to smoke at work. The predictive effects of past behaviour, anticipated regret, social norms, attitudinal, outcome expectancy and behavioural control beliefs were investigated in relation to the Attitudes-Social influence-self-Efficacy (ASE) model. METHODS: Data were collected from Greek non-smoker employees (n=137, mean age=33.5, SD=10.5, 54.7% female) in 15 companies. The main outcome measure was assertiveness intention. Data on participants' past smoking, age, gender and on current smoking policy in the company were also collected. RESULTS: The majority of employees (77.4%) reported being annoyed by exposure to passive smoking at work, but only 37% reported having asked a smoker colleague not to smoke in the last 30 days. Regression analysis showed that the strongest predictor of non-smokers' assertiveness intentions was how often they believed that other non-smokers were assertive. Perceived control over being assertive, annoyance with secondhand smoke (SHS) exposure at work and past assertive behaviour also significantly predicted assertiveness intentions. CONCLUSIONS: Assertiveness by non-smoker employees seems to be guided mainly by normative and behavioural control beliefs, annoyance with SHS exposure at work, and past behaviour. Interventions to promote assertiveness in non-smokers might benefit from efficacy training combined with conveying the messages that the majority of other non-smokers are frequently annoyed by exposure to SHS, and that nearly half of all non-smokers are assertive towards smokers.

Predicting Greek adolescents' intentions to smoke: a focus on normative processes.

OBJECTIVE: To examine the effects of normative influences on adolescent smoking in Greece, a country with weak social norms against smoking and relatively ineffective tobacco control policies. DESIGN: A cross-sectional survey methodology was employed, and a representative sample of Greek high school students was recruited (N = 1,920, M age = 14 years). MAIN OUTCOME MEASURES: Normative beliefs, attitudes, perceived behavioral control, self-esteem, and intentions to smoke. RESULTS: Multiple-regression and mediation analyses were conducted. The effects of public smoking on intentions to smoke were mediated by beliefs of perceived prevalence of smoking among peers, subjective norms, and situational temptations. Self-esteem significantly moderated the effects of subjective norms on intentions to smoke. CONCLUSIONS: Prosmoking norms in one's environment become internalized into biased normative beliefs about smoking, and increase susceptibility to smoke under social pressure. The effect of subjective norms on intentions to smoke was stronger among adolescents with low self-esteem, suggesting that self-esteem may act as a vulnerability factor in the process of smoking initiation.

Boundaries of self-positivity: the effect of comparison focus in self-friend comparisons.

The way in which a comparison is worded has systematic effects on its outcome. In self-other comparisons, the instruction "compare yourself with your peers" triggers greater self-positivity than does the reverse instruction, "compare your peers with yourself" (focus effect). But is the focus effect due to the inclusion of a generalized target? The authors extended the focus effect from comparisons with the average peer to comparisons with specific individuals (close friend or acquaintance). Participants displayed self-positivity when they compared themselves with a close friend but not when they compared a close friend with themselves. The present research is the first to demonstrate the focus effect in comparisons of self and specific individuals.

"Trust me, I'm a scientist (not a developer)": perceived expertise and motives as predictors of trust in assessment of risk from contaminated land.

Previous authors have argued that trust may be based on the extent to which risk communicators are seen as good at discriminating safety from danger, are unbiased in their assessments, and share their audience's values. Residents of two English urban regions rated their trust in six potential sources of information about the risk of contaminated land in their neighborhood (independent scientists; local council property developers; residents' groups; friends and family; local media), and how expert, open, accurate, or biased these sources were and how much they had residents' interests at heart. Overall, scientists were trusted most and developers least, but this was only partly due to their greater perceived expertise. Resident groups and friends/family were also trusted, despite being seen as relatively inexpert, since they scored highly on openness and shared interests, these latter two attributes being more important predictors of trust in individual sources than perceived expertise. We conclude that, where a source is seen as motivated to withhold, distort, or misinterpret information, this will undermine public trust even in apparently knowledgeable sources, hence supporting the view that trust depends on a combination of perceived expertise and perceived motives as complementary processes.

Prejudiced learning: a connectionist account.

Connectionist simulation was employed to investigate processes that may underlie the relationships between prior expectancies or prejudices and the acquisition of attitudes, under conditions where learners can only discover the valence of attitude objects through directly experiencing them. We compared contexts analogous to learners holding either false negative expectancies ('prejudices') about a subclass of objects that were actually good or false positive expectancies about objects that were actually bad. We introduced expectancy-related bias either by altering the probability of approach, or by varying the rate of learning following experience with good or bad objects. Where feedback was contingent on approach, the false positive expectancies were corrected by experience, but negative prejudices resisted change, since the network avoided objects deemed to be bad, and so received less corrective feedback. These findings are discussed in relation to the effects of intergroup contact and expectancy-confirmation processes in reducing or sustaining prejudice.

Who reaps the benefits, who bears the risks? Comparative optimism, comparative utility, and regulatory preferences for mobile phone technology.

Although the issue of risk target (e.g., self, others, children) is widely acknowledged in risk perception research, its importance appears underappreciated. To date, most research has been satisfied with demonstrating comparative optimism, i.e., lower perceived risk for the self than others, and exploring its moderators, such as perceived controllability and personal exposure. Much less research has investigated how the issue of target may affect benefit perceptions or key outcomes such as stated preferences for hazard regulation. The current research investigated these issues using data from a public survey of attitudes toward mobile phone technology (N= 1,320). First, results demonstrated comparative optimism for this hazard, and also found moderating effects of both controllability and personal exposure. Second, there was evidence of comparative utility, i.e., users believed that the benefits from mobile phone technology are greater for the self than others. Third, and most important for policy, preferences for handset regulation were best predicted by perceptions of the risks to others but perceived benefits for the self. Results suggest a closer awareness of target can improve prediction of stated preferences for hazard regulation and that it would be profitable for future research to pay more attention to the issue of target for both risk and benefit perceptions.

Marginal trust in risk managers: building and losing trust following decisions under uncertainty.

Although a considerable amount of research has examined correlates of baseline public trust in risk managers, much less research has looked at marginal changes in public trust following specific events. Such research is important for identifying what kinds of events will lead to increases and decreases in public trust and thus for understanding how trust is built and lost. Using a taxonomy based upon signal detection theory (SDT), the current article presents two experimental studies examining marginal trust change following eight different types of events. Supporting predictions, cautious decisionmakers who accepted signs of danger (Hits and False Alarms) were more likely to be trusted than those who rejected them (All Clears and Misses). Moreover, transparency about an event was associated with higher levels of marginal trust than a lack of transparency in line with earlier findings. Contrary to predictions, however, trust was less affected by whether the decisions were correct (i.e., Hits and All Clears) or incorrect (i.e., False Alarms and Misses). This finding was primarily due to a "False Alarm Effect" whereby Open False Alarms led to positive increases in trust despite being incorrect assessments of risk. Results are explained in terms of a cue diagnosticity account of impression formation and suggest that a taxonomy of event types based on SDT may be useful in furthering our understanding of how public trust in risk managers is gained and lost.

The focus effect and self-positivity in ratings of self-other similarity and difference.

We conducted 2 studies investigating comparative ratings of similarity or difference and the thoughts underlying these ratings. Participants compared either the self with others (self-->other focus) or others with the self (other-->self focus). People expressed higher distinctiveness under self-->other focus than under other-->self focus (focus effect) when rating difference in Studies 1 and 2, and when rating similarity in Study 1. Analyses of verbal reports showed that people mentioned the self more than others under self-->other focus, but mentioned self and others to the same extent under other-->self focus. Moreover, Study 2 showed that participants spontaneously made more positive statements for the self under self-->other focus than under other-->self focus. This effect was significantly mediated by the number of self-references made. Implications for recent models of social judgment are discussed.

Valence, comparison focus and self-positivity biases: does it matter whether people judge positive or negative traits?

The present research questions whether mere valence affects self-other comparisons in the domain of trait characteristics. While some previous studies have reported greater positivity bias for the self when traits were positive than when traits were negative, we suggest that this is an ambiguous finding, because valence and content were confounded. When we unconfounded content and valence, valence had no effect on the magnitude of self-positivity bias displayed. We also replicate several findings for our unconfounded set of traits. Firstly, comparing others to the self, rather than comparing the self to others, lowered self-positivity for positive and negative traits (focus effect). Secondly, extremely positive and negative traits triggered greater positivity bias than did more moderately evaluated ones. Finally, we suggest that comparative self-positivity biases may be based on a general positivity bias.

Quality of life in children newly diagnosed with cancer and their mothers.

BACKGROUND: With current treatments, approximately 75% of children diagnosed with cancer can expect to achieve disease-free survival. However, treatments are complex and aggressive, potentially compromising QOL for children and their parents. Although previous work has shown increased anxiety and depression among parents after diagnosis, the recent development of standardised measures of QOL enables us to look more directly at the impact of diagnosis on mothers' and children's QOL. The aims of this study are to i) describe QOL for children and their mothers after diagnosis by comparing their scores with population norms, ii) explore the relationship between mothers' worries about the illness and their QOL, and iii) determine the relationship between mothers ratings of their own QOL and their child. METHOD: A total of 87 families took part, constituting 60% of those eligible. The children included 58 males and 29 females aged between 2 years 6 months to 16 years 3 months (mean = 7 years, median = 5 years 8 months). Diagnoses were acute lymphoblastic leukaemia (ALL, n = 57), brain tumours (n = 11), bone tumours (n = 17) and 2 rare cancers. Mothers completed questionnaires about their own and the child's QOL. RESULTS: Mothers' reported their own and the child's QOL to be significantly lower than population norms. There were significant correlations between mothers' worries and their own and their ratings of the child's QOL and mothers' ratings of their own QOL correlated with their ratings of the child's QOL. CONCLUSION: Both children and their mothers experience significantly compromised QOL in the months following diagnosis. Mothers who rated their own QOL to be poor also rate their child's QOL to be low. These results suggest caution is required where mothers rate their child's QOL. Efforts must continue to be made to improve QOL of children especially in the period immediately following diagnosis.

Attitude formation through exploration: valence asymmetries.

The formation of attitudes toward novel objects was examined as a function of exploratory behavior. An initial experiment, in which participants played a computer game that required them to learn which stimuli, when sampled, produced favorable or unfavorable outcomes, demonstrated learning, attitude formation, and generalization to novel objects. The findings also revealed 2 interesting valence asymmetries: a learning asymmetry involving better learning for negatively valenced than positively valenced objects and a generalization asymmetry involving stronger generalization as a function of negative than of positive attitudes. Findings from 4 experiments led to an explanation of the learning asymmetry in terms of information gain being contingent on approach behavior and related the generalization asymmetry to a negativity bias that weighs resemblance to a known negative more heavily than resemblance to a positive.

Risk perceptions of mobile phone use while driving.

Numerous governments have introduced regulations governing the use of mobile (cellular) telephones while driving. Despite significant research into the "objective" risks, there is relatively little research into risk perceptions either in relation to other in-car distractions or with respect to the factors underlying such perceptions. The current article reports on two studies addressing these issues. Study 1 (N= 199) found that whereas the use of hand-held sets is seen as one of the riskiest activities to perform while driving, the risks of using a hands-free kit are perceived to be relatively small. Study 2 (N= 1,320) found that nearly half of all drivers in the sample with a mobile phone reported having used it while driving and that, overall, the probability of having an accident was perceived to be less for oneself than for one's peers, indicating an optimistic bias. Two factors underpinned risk perceptions, "impact" including perceived severity and equitability, and "controllability" including immediacy, detectability, and probability. While higher "impact" scores were associated with increased preferences for restrictions on the use of hand-held mobiles while driving, the "controllability" scores moderated this relationship such that when perceived "controllability" was low, restriction preferences were high irrespective of perceived "impact." However, when "controllability" was high, restriction preferences remained high when "impact" was high but were low when "impact" was low. Given the growing number of in-car technological innovations, it is suggested that regulators act strategically, rather than finding themselves developing a series of "hazard-specific" regulations, which may ultimately lack coherence.

Surviving childhood cancer: quality of life and parental regulatory focus.

Applying Regulatory Focus Theory (RFT), the authors predicted that among survivors of childhood cancer, quality of life (QOL) may be compromised by prevention-focused parenting characterized by an overly protective concern with possible mishaps and illness recurrence rather than promotion-focused parenting encouraging expectations of recovery and a normal life. Interviews with parents of 64 survivors (M age = 13.83 years) of acute lymphoblastic leukemia (ALL) or central nervous system (CNS) tumors were coded for reports of promotion or prevention-oriented parenting and positive and negative expectancies. Overall, parents expressed more promotion than prevention focus, especially in relation to general rather than illness-related contexts. Greater use by parents of prevention focus in general contexts predicted lower QOL for survivors (as rated both by parents and survivors themselves) and less satisfactory parental well-being. These effects were independent of a main effect for type of cancer, with survivors of ALL having higher QOL.

Connectionist simulation of attitude learning: asymmetries in the acquisition of positive and negative evaluations.

Connectionist computer simulation was employed to explore the notion that, if attitudes guide approach and avoidance behaviors, false negative beliefs are likely to remain uncorrected for longer than false positive beliefs. In Study 1, the authors trained a three-layer neural network to discriminate "good" and "bad" inputs distributed across a two-dimensional space. "Full feedback" training, whereby connection weights were modified to reduce error after every trial, resulted in perfect discrimination. "Contingent feedback," whereby connection weights were only updated following outputs representing approach behavior, led to several false negative errors (good inputs misclassified as bad). In Study 2, the network was redesigned to distinguish a system for learning evaluations from a mechanism for selecting actions. Biasing action selection toward approach eliminated the asymmetry between learning of good and bad inputs under contingent feedback. Implications for various attitudinal phenomena and biases in social cognition are discussed.

Interpretations of Risk and Expectations of Change among Individuals with Types 1 and 2 Diabetes.

Questionnaires to assess expectations of future health were administered to 382 patients with diabetes immediately before and after attending an annual check-up. When considering their future health status and interpreting feedback from clinicians, diabetic control appeared to be a more important criterion for Type 1 than Type 2 patients. Both patients and clinicians briefly recorded the topics they felt had been discussed during the consultation. Comparing the two sets of records revealed significant concordance, within the Type 1 but not the Type 2 sample, between patients and clinicians with respect to whether patients had been given good news. Our findings emphasize the importance of distinguishing Types 1 and 2 diabetes in accounts of patients' expectations and motivation for self-management.
