Background: Based on the assumptions that depersonalization symptoms are relevant for test anxiety maintenance, we examined their frequency, psychological predictors, association with anxiety symptoms, and association with test performance. Sampling and Methods: In Study 1, 203 students rated their test anxiety severity and depersonalization in their last oral examination. In Study 2, we assessed test anxiety 1 week before an oral examination, depersonalization, safety behaviors, self-focused attention, and negative appraisals of depersonalization directly after the examination, and post-event processing 1 week later among 67 students. Results: In Study 1, 47.3% reported at least one moderate depersonalization symptom. In Study 2, test anxiety and negative appraisals of depersonalization significantly predicted depersonalization. Depersonalization was linked to a higher intensity of safety behaviors and post-event processing but not to self-focused attention. It was not related to performance. Conclusion: Results are limited by the non-random sampling and the small sample size of Study 2. However, by showing that depersonalization contributes to the processes the maintenance of test anxiety, the findings confirm that depersonalization – normally understood as an adaptive mechanism to cope with stressful events – can become maladaptive.

Human related accidents in high-risk industries amount to a significant economic hazard and incur tremendous damages, causing excessive operational costs and loss of life. The aviation industry now observes human-related accidents more frequently than in the past, an upswing attributable to cutting-edge technology usage and the complex systems employed by aviation organizations. Historically, aviation accidents have been attributed to individual unsafe behavior. However, contemporary accident causation models suggest that organizational-level factors influence individual safety performance, as human-related accidents take place in an organizational context. The present study examines the formation of organizational safety culture and influence on individuals' safety behavior in a police aviation environment. The theory of planned behavior guides the study model in explaining individual variability in safety behavior via organizational safety culture. The study conceptualized organizational safety culture and individual safety behavior as multidimensional constructs. Confirmatory factor analysis was conducted for each latent construct to validate the construct validity for each measurement model. Organizational safety culture was observed via safety climate facets, which contained four subcomponents including individual attitude, group norms, management attitude, and workplace pressures. Individual safety behavior contained violation and error components observed by self-reported statements. Structural equation modeling was conducted to test the study hypotheses. Utilizing a sample of 210 employees from the Turkish National Police Aviation Department, a 53-item survey was conducted to measure individuals' safety culture perceptions and self-reported safety behaviors. The results suggest that individual safety behavior is significantly influenced by organizational safety culture. Except for the relation between workplace pressures and intention, all suggested relations and correlations were statistically significant. The four-factor measurement model of organizational safety climate fit reasonably well to the data, and most correlations between the safety climate components were significant at the .05 level. Individuals' self-reported error behavior is positively associated with age, and individuals' self-reported violation behavior is positively associated with years of service. Overall, along with organizational safety culture, age and service-year variables accounted for 65% of the variance in intention, 55% of the variance in violation behavior, and 68% of the variance in error behavior. Lastly, no significant difference manifested among pilots, maintenance personnel, and office staff according to their self-related safety behaviors. The findings have theoretical, policy, and managerial implications. First, the theory of planned behavior was tested, and its usefulness in explaining individuals' safety behavior was demonstrated. The survey instrument of the study, and multi-dimensional measurement models for organizational safety climate and individual safety behavior were theoretical contributions of the study. Second, the emergence of informal organizational structures and their effects on individuals indicated several policy implications. The study also revealed the importance of informal structures in organizations performing in high-risk environments, especially in designing safety systems, safety policies, and regulations. Policy modification was suggested to overcome anticipated obstacles and the perceived difficulty of working with safety procedures. The influences of age on error behavior and years of service on violation behavior point to the need for several policy modifications regarding task assignment, personnel recruitment, health reports, and violation assessment policies. As well, managerial implications were suggested, including changing individuals' perceptions of management and group attitudes toward safety. The negative influence of anticipated obstacles and the perceived difficulties of safety procedures on individual safety behavior pointed out management's role in reducing risks and accidents by designing intervention programs to improve safety performance, and formulating proactive solutions for problems typically leading to accidents and injuries.

Den här undersökningen utgår från teorier om riskperception och Theory of Planned Behaviour (TPB). Syftet med studien var att, med utgångspunkt i teorier om riskperception och Theory of Planned Behaviour (TPB), undersöka individers riskperception och säkerhetsbeteende gentemot trafikolyckor. Undersökningen ville också studera om riskperceptionen och säkerhetsbeteendet är varierar beroende på vem som riskeras att utsättas för risken och vem som ska utföra ett visst beteende. Vidare kopplas det till bakgrundsvariabler som kön och tidigare erfarenheter. Studien utfördes i svensk kontext. Metoden var av kvantitativ ansats och datainsamlingsmetod var enkätstudier. Enkäten var konstruerad utifrån teorierna och undersökningen syfte. Enkäten spreds på Facebook och hade ett bekvämlighetsurval. Totalt svarade 102 personer på enkäten. Studien kom fram till att tidigare erfarenheter har en mycket liten inverkan på individens riskperception av trafikolyckor, både vad gäller risken för individen personligen men också risken för människor i allmänhet. Kön däremot påverkar individens riskperception i högre grad. En annan slutsats var att tidigare erfarenheter har mycket liten påverkan på människors säkerhetsbeteende, både för individens eget beteende men också för individens benägenhet att uppmana människor i allmänhet att bete sig på ett visst sätt. Vidare visade det sig att kön har större påverkan på säkerhetsbeteendet, både vad gäller individen eget beteende men också individens tendens att uppmana människor i allmänhet. En sista upptäckt var att studien fann att riskperception och beteende inte är oberoende av varandra där den ena påverkas av den andra utan snarare är de beroende av och påverkar varandra.  En notis är att undersökning fann att lagar kan skapa ett medvetet säkerhetsarbete. Det innebär att den nya lagen om mobilanvändning vid bilkörning i Sverige är rätt väg att gå för att skapa ett säkert beteende. / This study is based on theories of risk perception and Theory of Planned Behavior (TPB). The purpose of the study was to investigate individuals' risk perception and safety behavior in relation to traffic accidents, based on theories of risk perception and Theory of Planned Behavior (TPB). The survey also wanted to study whether risk perception and safety behavior vary depending on who is at risk of being exposed to the risk and who should perform a certain behavior. Furthermore, it is linked to background variables like gender and previous experiences. The study was conducted in Swedish context. The method was quantitative and data method was questionnaire. The survey was based on the theories and the investigation purpose. Furthermore, the survey was spread on Facebook and had a comfort check. In total, 102 people answered the questionnaire. The study found that past experience has a very small impact on individuals' risk perception of traffic accidents, both in terms of the individual's risk but also the risk for people in general. Gender, on the other hand, affects the individual's risk perception to a greater extent. Research also found that previous experiences have a very small impact on the safety behavior of individuals, both in terms of the risk of the individual's own behavior but also regarding the individual's requests for people in general. Furthermore, it has been shown that gender has an influence on safety behavior, both regarding the risk of the individual's own behavior, but also regarding the individual's requests for people in general. Finally, the study found that risk perception and behavior are not independent of each other where one is influenced by the other, but rather they depend on and affect each other. One note is that the study showed that laws can create a conscious security work. This means that the new law on mobile use when driving in Sweden is the right way to go to manifest safe behavior.

Indiana University-Purdue University Indianapolis (IUPUI) / Safety researchers have devoted extensive attention to safety performance behaviors. However, current safety performance models have yet to differentiate between safety citizenship behaviors directed towards the organization and those directed towards individuals. This might be a potential oversight, considering that citizenship behaviors targeted at different beneficiaries might be associated with different antecedents. As such, the purpose of the present study was to develop and validate a new safety performance scale. Items from existing measures formed the item pool and those tapping into the proposed dimensions were selected. Next, items were pilot tested using an online panel of 333 employees from various safety-related industries. A 4-factor structure emerged after exploratory factor analysis and the scale was further refined using reliability analysis and item response theory analysis. Finally, confirmatory factor analysis was conducted to replicate the factor structure using data from 137 employees. Theoretically related variables were correlated with the safety performance dimensions to establish the nomological network. Results supported the 4-factor structure of the new safety performance scale and construct validation hypotheses were largely supported. Implications, study limitations, and directions for future research are discussed.
