Abstract

Introduction: Using leading indicators to determine organizations’ ability and willingness to learn fromsafety-related events can significantly enhance occupational health and safety management systems andhelp prevent future incidents.

Material and Methods: This study aimed to assess the psychometric properties of the Persian version ofthe propensity to learn from experiences related to safety events questionnaire, among 352 operators andmanagers (92% response rate), using quantitative and qualitative techniques to assess face and contentvalidity, construct validity, and reliability coefficients.

Results: Out of 49 items in the questionnaires, 48 demonstrated acceptable levels of face and contentvalidity, with content validity indices ranging from 0.80 to 1. Reliability scores assessed through internalconsistency (Cronbach’s alpha) and intraclass correlation coefficients were reported as 0.80 and 0.95 forthe 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’ measurementmodel, supported by a larger sample size of 271 compared to 81 for managers, yielded superior results interms of parsimonious and adaptive fit indices.

Conclusion: The Persian version of learning from experiences related to safety events questionnaire isa valid and reliable instrument for identifying learning weaknesses at both individual and organizationallevels and can be utilized as a leading indicator to enhance safety culture and event’s learning processes
