Background and objectives: Terrorism can heighten fears and undermine the feeling of safety. Little is known, however, about the factors that influence threat and safety perception after terrorism. The aim of the present study was to explore how proximity to terror and posttraumatic stress reactions are associated with perceived threat and safety after a workplace terrorist attack. Design and methods: A cross-sectional questionnaire survey was administered to employees in 14 of 17 Norwegian ministries 9–10 months after the 2011 bombing of the government headquarters in Oslo (n = 3520). Results: About 198 of 1881 employees completing the survey were at work when the bomb exploded. Regression analysis showed that this high-exposed group had elevated perceived threat (β = 0.36; 95% CI = 0.19 to 0.53) and reduced perceived safety (β = ?0.42; 95% CI = ?0.62 to ?0.23) compared to a reference group of employees not at work. After adjusting for posttraumatic stress reactions, however, proximity to the explosion no longer mattered, whereas posttraumatic stress was associated with both high perceived threat (β = 0.55; 95% CI = 0.48 to 0.63) and low perceived safety (β = ?0.71; 95% CI, ?0.80 to ?0.63). Conclusion: Terror-exposed employees feel more threatened and less safe after a workplace terrorist attack, and this is closely linked to elevated levels of posttraumatic stress reactions.  相似文献

In this study we aim to increase our understanding of leadership in anaesthesia teams by investigating the relationship between substitutes for leadership, leadership behaviour, and team performance in situations with varying levels of routine and standardization. The present study relied on video recordings of 12 anaesthesia teams in a simulated setting with the occurrence of a nonroutine event. Clinical team performance was measured by the speed of adequate team reaction to this event. The leadership behaviours observed were coded either as content oriented (e.g., information transmission) or structuring (e.g., assigning tasks). Results showed that leadership behaviour changed depending upon the level of routine of a situation, the degree of standardization, and, to some extent, on the experience of team members. Leadership tends to be positively related to team performance during nonroutine and low standardized situations but negatively related to team performance in routine and highly standardized situations. Furthermore, leadership is only slightly related to team member experience. This study improves our understanding of influences of substitutes for leadership on successful leadership behaviour in anaesthesia teams. The findings also lead to suggestions for both further research and the enhancement of team leadership in critical care.  相似文献

ABSTRACT

Junior doctors’ exposure to bullying may impact their training and compromise quality healthcare, yet little is known in relation to its predictors and effects. The aim of this paper is to assess the prevalence, factors and outcomes of workplace bullying among junior doctors. Literature search was performed to identify all primary studies examining workplace bullying among junior doctors using the following electronic databases: Medline, Scopus, Web of Science, PsycINFO and Cochrane Library. A total of 18 articles were included, reporting on a total of 9,597 junior doctors. The quality of evidence can be rated as moderate according to the Newcastle Ottawa Scale. From the review, a wide range (30–95%) of bullying prevalence, significant differences in bullying rates according to gender, age, height, ethnicity and subspecialty, and significant associations between bullying and mental strain, job dissatisfaction, burnout, and increased accidents at work were observed. Concurrently, heterogeneity in the terms and methodologies used to examine workplace bullying as well as definitional issues in relation to the persistency of negative interactions were noted. Evidence suggests that workplace bullying is a serious occupational hazard for junior doctors, and more research is warranted to better understand this phenomenon and address its definitional and methodological issues.  相似文献

Speaking up in high-risk organizations plays a pivotal role in the mitigation of errors and can make the difference between life and death. To date, speaking up has been studied mostly within teams. However, many high-risk organizations rely on the effective collaboration across teams in ad hoc multiteam systems (MTS). This study widens the scope of research from teams to MTS and empirically compares the mechanisms involved in speaking up within versus across teams in ad hoc MTS-aircrews. In a sample of 1490 aircrew members of a European airline, we found that crewmembers’ individual level perceptions of psychological safety mediated both the relationship between status and speaking up and between perceived leader inclusiveness and speaking up within teams. Across teams, however, psychological safety and leader inclusiveness—as perceived by pursers in their role as boundary spanners—showed no effect. Instead, it was pursers’ within-team perceptions of psychological safety that mediated between status and speaking up across teams. Teams in ad hoc MTS may thus serve as safe harbours supporting their members also in interactions across team boundaries. Implications of findings for research on MTS and practical recommendations to improve speaking up within and across teams in ad hoc MTS are discussed.  相似文献

How do we set standards in assessing spiritual well-being (SWB)? Most measures provide only scores on arbitrary scales. Therefore, if the questions differ, the scores are likely to as well. This paper reports on two scales developed with 460 Australian secondary school students, with diverse cultural and religious backgrounds, from state, Catholic, Christian Community and independent schools. The four domains model of spiritual health/well-being was the theoretical base from which 12 items were developed to reflect quality of relationships with each of self, others, environment and God/the Divine. The instrument with the five top-scoring items in each domain, known as Spiritual Health And Life-Orientation Measure (SHALOM), has been sought for use in over 200 studies in 20 languages. The second-highest sets of five items were extracted and found to form statistically valid factors, for a new instrument called SWBQ2. As would be expected, the mean values for the factor scores varied between SHALOM and SWBQ2, overall and by school type. However, regression analyses of the lived experience scores showed that relating with God provided greatest explanation of variance in SWB, on both measures. A double-response method introduced for SHALOM was also used with SWBQ2 to compare each person’s lived experience with their ideals, better reflecting quality of relationships, rather than just the arbitrary scores. There was negligible difference in dissonance scores on the four factors in both measures, that is, in comparing the difference between ideals and lived experiences. This method showed consistency in the quality of relationships reflecting SWB, contrasted with variance shown using only lived experience, as mentioned above. Relating with God was again most influential on SWB. These findings have implications for methods used in assessing SWB as well as outcomes.  相似文献

In this paper, we systematically review the growing empirically based psychology of Islam. We arrive at 10 conclusions: (l) Islam is a multidimensional religion; Islam might mean different things to different people, and some people might adhere to some of its elements but not to others; (2) Islam is similar to, but is different from, other religions; (3) Islam's role in the lives of Muslims seems mostly positive; (4) Some types of Islamic religiousness are negative; (5) The empirical findings have not been translated yet into clinical applications; (6) Most of studies conducted among Muslims provide only a birds-eye view of Islam; (7) Empirical studies of Muslims are scarce; (8) Empirical research on negative types of religiousness among Muslims is sparse; (9) The majority of research in this field has been restricted to convenient samples; (10) Several important topics with implications for Muslims deserve further consideration, and there is a need for more varied research methods in studies of Muslims. The implications of these findings and the limitations of this review are discussed.  相似文献

Although the presence of significant limitations in adaptive behavior constitutes one of the three necessary criteria for diagnosing intellectual disability, adaptive behavior structure has always been the subject of considerable controversy among researchers. The main goal of this study is to extend previous research results that provide further support to a multidimensional structure of conceptual, social, and practical skills compared to the unidimensional structure. One-factor and 3-correlated factors models as measured by 15 observable indicators were analyzed by means of confirmatory factor analysis (CFA), as well as their relationships with one second-order factor (i.e., adaptive behavior). To that end, 388 children with and without intellectual disabilities were assessed with the Diagnostic Adaptive Behavior Scale (DABS). Results of CFA indicated that the 3 first-order factors solution provides the best fit to the data. Reliability and validity of the multidimensional model were also analyzed through different methods such as the composite reliability and the average variance extracted. Finally, implications of these findings and possible directions for future research are discussed.  相似文献

Growing popular interest in positive psychology may have important implications for the measurement of well-being. Five studies tested the prediction that well-being ratings are influenced by desirability bias. In Study 1, participants (N?=?176) instructed to fake good endorsed higher well-being; those instructed to fake bad endorsed lower well-being, compared to controls. In Studies 2 and 3 (N’s?=?111, 121), control participants endorsed higher levels of well-being compared to those attached to a bogus pipeline. These differences were mediated by desirability bias. In Study 4 (N?=?417), instruction manipulations did not affect well-being levels, but presenting a desirability measure prior to well-being measures attenuated the correlations between them. In Study 5 (N?=?391), however, this order effect did not replicate. We discuss the importance of continued vigilance for desirability bias in well-being research as a ready solution to this clear problem remains elusive.  相似文献

This study examined associations between self-reported mental health problems, body image, bullying victimisation and school safety in large adolescent samples in Japan and Russia, considering the effects of gender, culture and their interactions. In both Japan and Russia, girls reported a greater number of mental health problems, less bullying victimisation and much higher body dissatisfaction than boys did. Japanese adolescents rated themselves higher on total difficulties, reported less body dissatisfaction and bullying victimisation, and rated their school safety lower than that of Russian youths. Cross-cultural differences in total difficulties and body image were qualified by gender. Body dissatisfaction, bullying victimisation and school safety all independently contributed to adolescent mental health problems. The protective effect of school safety on total difficulties was larger for girls than for boys; the strength of the association between bullying victimisation and adolescent mental health problems differed across genders and cultures. The findings indicate a need for a cross-cultural approach and provide a strong basis for targeted interventions that seek to improve adolescent mental health.  相似文献

The present study aimed at identifying subtypes of young drivers (N=2524) and evaluate how these responded to a traffic safety campaign. On basis of a cluster analysis of personality measures, six subtypes of young drivers were identified. The subtypes were found to differ on self-reported risky driving behaviour, attitudes towards traffic safety, risk perception, estimation of own driving skills, and accident involvement. Two of the subtypes were identified as high-risk groups in traffic. The first high-risk group consisted of mostly men, characterised by low levels of altruism and anxiety, and high levels of sensation-seeking, irresponsibility, and driving related aggression. The second high-risk group reported high sensation seeking, aggression, anxiety, and driving anger. The subtypes were also found to differ on how they evaluated and responded to the traffic safety campaign. The results indicated that the campaign seemed to appeal most to the low-risk subtypes. Gender differences within each subtype were also found on the different traffic related measures, as well as on response to the campaign. It is concluded that young drivers should not be treated as a homogenous group pertaining to road safety. Practical suggestions on how to promote safe driving among these subtypes are also discussed.  相似文献
