Objective: Workplace safety culture plays a critical role in preventing occupational risks and improving worker well-being.

This study aims to validate an instrument for measuring the level of safety culture in Peru to identify critical improvement areas and support evidence-based strategies. Method: A three-part validation was conducted: selection of the instrument through a review of the scientific literature, qualitative validation through expert judgment, and quantitative validation via a pilot test with 42 workers. Reliability was assessed using Cronbach’s alpha and McDonald’s omega, while construct validity was examined using Exploratory Factor Analysis with Unweighted Least Squares and Promax rotation. Results: The validated instrument consists of 16 questions grouped into fiv...
