Previous studies have acknowledged the relevance of assessing the measurement equivalence of safety related measures across different groups, and demonstrating whether the existence of disparities in safety perceptions might impair direct group comparisons. The Griffin and Neal (2000) model of safety climate, and the accompanying measure (Neal et al. [NGH], 2000), are both widely cited and utilized. Yet neither the model in its entirety nor the measure have been previously validated across different national contexts. The current study is the first to examine the NGH measurement equivalence by testing whether their model of safety climate predicting safety performance is tenable in both English speaking and non-English speaking countries. The study involved 616 employees from 21 organizations in the US, and 738 employees from 20 organizations in Italy. A multi-group confirmatory factor analytic approach was used to assess the equivalence of the measures across the two countries. Similarly, the structural model of relations among the NGH variables was examined in order to demonstrate its cross-country invariance. Results substantially support strict invariance across groups for the NGH safety scales. Moreover, the invariance across countries is also demonstrated for the effects of safety climate on safety knowledge and motivation, which in turn positively relate to both compliance and participation. Our findings have relevant theoretical implications by establishing measurement and relational equivalence of the NGH model. Practical implications are discussed for managers and practitioners dealing with multi-national organizational contexts. Future research should continue to investigate potential differences in safety related perceptions across additional non-English speaking countries.
先前的研究已经承认了评估不同群体之间安全相关措施的测量等效性的重要性,并证明安全感知方面的差异是否会影响直接的群体比较。格里芬和尼尔(2000)的安全氛围模型以及相应的测量方法(尼尔等人,2000)被广泛引用和使用。然而,无论是整个模型还是测量方法都没有在不同的国家背景下进行过验证。本研究首次通过检验安全氛围模型对安全绩效的预测是否在英语国家和非英语国家都具有可操作性,来检验 NGH 的测量等效性。该研究涉及来自美国 21 个组织的 616 名员工和来自意大利 20 个组织的 738 名员工。采用多组验证性因素分析方法来评估两个国家的测量等效性。同样,还检验了 NGH 变量之间的结构模型关系,以证明其在跨国的不变性。结果基本上支持 NGH 安全量表在群体间的严格不变性。此外,还证明了安全氛围对安全知识和动机的影响在国家间具有不变性,而安全知识和动机反过来又与合规性和参与度呈正相关。我们的研究结果通过建立 NGH 模型的测量和关系等效性,具有重要的理论意义。为了处理跨国组织背景,讨论了对管理者和从业者的实际意义。未来的研究应该继续调查在额外的非英语国家中,与安全相关的感知方面的潜在差异。
