Safety climate and safety culture are important research domains in risk and safety science, and various industry and service sectors show significant interest in, and commitment to, applying its concepts, theories, and methods to enhance organizational safety performance. Despite the large body of literature on these topics, there are disagreements about the scope and focus of these concepts, and there is a lack of systematic understanding of their development patterns and the knowledge domains on which these are built. This article presents a comparative analysis of the literature focusing on safety climate and safety culture, using various scientometric analysis approaches and tools. General development patterns are identified, including the publication trends, in terms of temporal and geographical activity, the science domains in which safety culture and safety climate research occurs, and the scientific domains and articles that have primarily influenced their respective development. It is found that the safety culture and safety climate domains show strong similarities, e.g., in dominant application domains and frequently occurring terms. However, safety culture research attracts comparatively more attention from other scientific domains, and the research domains rely on partially different knowledge bases. In particular, while measurement plays a role in both domains, the results suggest that safety climate research focuses comparatively more on the development and validation of questionnaires and surveys in particular organizational contexts, whereas safety culture research appears to relate these measurements to wider organizational features and management mechanisms. Finally, various directions for future research are identified based on the obtained results.

An exponential amount of academic research has been dedicated to the safety culture concept, but still, no consensus has been reached on its definition and content. In general, safety culture research lacks an interdisciplinary approach. Furthermore, although the concept of safety culture is characterised by complexity and multifacetedness, the safety culture concept has been characterised by reductionism, where models and theories simplify the concept in order to better grasp it, leading to confined approaches. In this article, the multifacetedness of safety culture is acknowledged, and the topic is addressed from a safety science perspective, combining insights from multiple academic disciplines. An integrative and comprehensive conceptual framework to assess safety culture in organisations is developed, taking into account the limitations of existing models, as well as the needs of the work field. This conceptual framework is called the ‘Integrated Safety Culture Assessment’ (ISCA), where the ‘assessment’ refers to its practical usability. The practical rendition of ISCA can be used to map the safety culture of an organisation and to formulate recommendations in this regard, with the ultimate goal of bringing about a change towards a positive safety culture. The comprehensiveness of ISCA lies in the inclusion of technological factors, organisational or contextual factors and human factors interacting and interrelating with each other, and in considering both observable or objective safety-related aspects in an organisation, and non-observable or subjective safety-related aspects. When using ISCA, organisational safety culture is assessed in an integrative way by using a variety of research methods involving the entire organisation, and by taking into account the specific context of the organisation.
