When management is committed to safety, this shows employees that safety is an important value to the organization, which, in turn, affects employees’ safety behavior. Although the number of studies that explore the concept of safety commitment has considerably increased in recent years, the main question that remains to be answered is how managers can most effectively demonstrate their commitment to safety to employees and through what mechanisms. In this paper, we examined the relationship between managers’ commitment to safety and employees’ perceptions of managers’ commitment to safety, with a specific focus on the potential mediating effect of managers’ leadership style. <em>Method</em>: To explore the proposed relationship, we performed an explanatory quantitative study on a sample of 147 respondents from six safety–critical organizations in the EU. By employing a mediation model, we were able to gain a better understanding of the role that transformational leadership can play when managers demonstrate their safety commitment to employees. <em>Results</em>: The results showed a positive and significant relationship between managers’ commitment to safety and employees’ perceptions of managers’ commitment to safety. Furthermore, we found a statistically significant difference between managers’ and employees’ perceptions. The mediation analysis also confirmed that leadership style mediates the relationship between managers’ commitment to safety and employees’ perceptions of managers’ commitment. <em>Conclusions</em>: This paper adds to the understanding of how managers can demonstrate their commitment to safety through their leadership and how managers’ leadership style helps to shape employees’ perceptions. <em>Practical Application</em>: The findings highlight the relevance of managers’ safety commitment and transformational leadership style for employees’ perceptions of managers’ safety commitment, which is a known antecedent of safety performance.</div></div>","PeriodicalId":48224,"journal":{"name":"Journal of Safety Research","volume":"92 ","pages":"Pages 230-244"},"PeriodicalIF":3.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143100945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of these objectives is to improve the safety training. <em>Method:</em> Focusing on this point and considering the safety training offered to construction workers in Spain, in the first hypothesis, we propose that more safety training reduces accidents by separating mandatory and voluntary training. In Hypothesis 2, we analyze whether voluntary training has a greater effect on reducing accidents than mandatory training. Finally, in Hypothesis 3, we test whether specific training is more effective than general training in reducing accidents. To test these hypotheses, we used data from training providers, accident data from the Labor Authority, and economic data from Informa &amp; Bureau van Dijk (SABI). The final sample comprises data from 1,283 Spanish construction companies over 11 years (2007–2017). The methodology involved analyzing the relationship between training and accidents, addressing our variables’ apparent endogeneity using instrumental variables. We analyzed the effect of accident training in the same year and, based on the learning curve theory, we also considered the previous three years of training. <em>Results:</em> Contrary to our hypotheses, our results show that more hours of safety training of all types are associated with more accidents, questioning its effectiveness. This finding highlights the need for an in-depth analysis of the training process to identify areas for improvement.

The objective of this study was to assess caregivers’ beliefs and awareness related to older adult falls and evidence-based prevention strategies. <em>Methods:</em> Questions about falls were included in the SummerStyles survey, part of the 2022 suite of Porter Novelli ConsumerStyles surveys.

Previous research revealed younger personnel (aged 13–25) are at a higher risk of post-traumatic stress (PTS) and other mental health impacts compared with older counterparts. This exploratory study aims to identify and articulate the needs of this demographic and their preferences towards creating a tailored mental health toolkit. <em>Methods:</em> An anonymous, online survey of Surf Life Saving Australia (SLSA) membership was conducted to measure mental health, to understand members’ preferences for appropriate mental health content and activities, and preferred toolkit formats. <em>Results:</em> Survey data (lifesavers aged 13–25; N = 82) highlighted high prevalence of mental health concerns, including PTS symptoms (PTSS), previous mental health diagnoses, and high rates of a friend with a mental health concern among respondents. A relationship (r = -0.52) was found between both levels of stigma and levels of social support and PTSS. PTSS was found to separately correlate with both lower levels of social support and higher levels of stigma. Although mental health literacy confers other benefits, we found no significant correlation between mental health literacy levels and PTSS. There was a heterogeneity of preferences for toolkit content, particularly in comparing older and younger SLSA members of the 13–25 years cohort. <em>Conclusions:</em> Mental health toolkits may help address PTSS, particularly if delivered as part of wider mental health promotion efforts. Specifically, stigma and social support can be targeted in future toolkits. <em>Practical Applications:</em> This study supports development of resources to support younger members within a first responder organization.

To enhance the understanding of e-scooter riding risks, this study conducted a nationwide crash analysis using a UK dataset. It explores the spatial and environmental contexts of e-scooter crashes and the factors influencing crash severity. <em>Method:</em> A comprehensive approach, including exploratory data analysis, latent class analysis (LCA), <em>chi-square</em> test, and logistic regression model, were employed. <em>Results:</em> Findings revealed distinctive spatiotemporal patterns in e-scooter crashes compared to overall crashes, with a higher incidence in deprived communities.
