Introduction: Using leading indicators to determine organizations’ ability and willingness to learn from safety-related events can significantly enhance occupational health and safety management systems and help prevent future incidents.
Material and Methods: This study aimed to assess the psychometric properties of the Persian version of the propensity to learn from experiences related to safety events questionnaire, among 352 operators and managers (92% response rate), using quantitative and qualitative techniques to assess face and content validity, construct validity, and reliability coefficients.
Results: Out of 49 items in the questionnaires, 48 demonstrated acceptable levels of face and content validity, with content validity indices ranging from 0.80 to 1. Reliability scores assessed through internal consistency (Cronbach’s alpha) and intraclass correlation coefficients were reported as 0.80 and 0.95 for the operators’ questionnaire and 0.95 and 0.92 for the managers’ questionnaire, all deemed acceptable. Confirmatory factor analysis indicated that both measurement models for operators and managers, comprising 12 dimensions each, exhibited strong construct validity. Notably, the operators’ measurement model, supported by a larger sample size of 271 compared to 81 for managers, yielded superior results in terms of parsimonious and adaptive fit indices.
Conclusion: The Persian version of learning from experiences related to safety events questionnaire is a valid and reliable instrument for identifying learning weaknesses at both individual and organizational levels and can be utilized as a leading indicator to enhance safety culture and event’s learning processes.
