Exploratory Study for the Adaptability of Trust Leading Indicator and Proactive Leading Indicator Based on Prevention Culture

Background: This study explored the applicability of the Trust Leading Indicator (TLI) and Proactive Leading Indicator (PLI), developed as part of the Vision Zero, a global campaign for the dissemination of prevention culture, in Korean industries. The relationship between these indicators and safety culture-related variables were compared, such as safety climate, safety behavior, risk perception, and accident experience. Methods: The study sample comprised 630 workers from 12 subcontractors affiliated with the Republic of Korea's large manufacturing plant. Correlations among the main variables were examined, including group differences in TLI and PLI based on subjective accident experience. Results: The TLI and PLI had significant positive correlations with the sub-factors of safety climate and safety behavior and negative correlations with risk perception, indicating their potential utility as extensions of existing safety culture indicators. A significant difference in TLI and PLI was observed across accident experience levels. Conclusion: Despite limitations, such as the predominance of male workers in the study owing to the nature of the industry and use of subjective accident experience rather than official industrial accident data, this study is significant as it explores the applicability of the two leading indicators of prevention culture in Korean industries, confirming the potential utility of these indicators across various cultural contexts and contributing to global efforts to disseminate a prevention culture.
