Background and Objective: If workers cannot accurately assess the level of risks in their work environment, they may become involved in work-related accidents. Therefore, this study aimed to design tools for measuring factors affecting safety risk perception in the workplace and to evaluate their validity and reliability.
Materials and Methods: This cross-sectional study was conducted in several phases. First, the factors affecting safety risk perception were identified. Then, existing tools for measuring these variables were reviewed. Subsequently, a suitable tool was designed with the assistance of a team of experts. Finally, the linguistic, face, construct, and content validity, as well as the reliability of the designed questionnaires, were determined using scientific methods.
Results: Standard questionnaires were designed for 8 variables, including safety climate, peer pressure, safety motivation, estimation of the level of implemented safety measures, assessment of the safety expert's knowledge and competency, the quantity and quality of safety training, experience of accidents and near-misses, and risk perception. The validity and reliability of these questionnaires were confirmed. The item impact score for the questionnaire questions was above 1.5. Furthermore, exploratory factor analysis determined the dimensions of the questionnaires. The content validity index (CVI) and content validity ratio (CVR) of the questionnaires were confirmed using the Lawshe method. Additionally, the reliability of the questionnaires was examined and confirmed using Cronbach's alpha and test-retest methods.
Conclusion: In the present study, standard instruments were designed for 8 main variables with ease of use so that they can be used in studies and evaluations.
