Development and validation of a questionnaire on safety culture elements preference for oil and gas industry

Introduction: The oil and gas industry is characterized by its inherently high-risk environment, necessitating a robust safety culture to prevent accidents and protect employees. Given the sector's complexity and the critical nature of its operations, a systematic assessment of safety culture is essential for enhancing safety performance. However, there remains a notable absence of standardized tools specifically designed to measure safety culture within the oil and gas industry. This study aims to develop and validate a Safety Culture Questionnaire (SCQ) tailored for the oil and gas industry to systematically assess safety culture. Materials and methods: The SCQ was developed based on an extensive literature review and consultation with academician and industry experts. The questionnaire is structured based on four key constructs derived from safety culture frameworks: psychological (6 items), situational (15 items), behavioural (28 items), and element preference (3 items), totaling 52 questions. Content validity was assessed by a panel of seven experts, and reliability was evaluated using Cronbach's Alpha. Results: The Content Validity Index (CVI) ranged from 0.86 to 1.00, indicating strong validity. Cronbach’s Alpha values demonstrated excellent reliability: 0.926 (psychological), 0.923 (situational), 0.982 (behavioural), and 0.912 (element preference). Conclusion: The validated SCQ is a reliable and valid tool for assessing safety culture in the oil and gas industry. It can be used to identify safety culture strengths and weaknesses, enabling organizations to target interventions more effectively and ultimately improve safety culture.
