Psychometric properties of the shortened version of Questionnaire of the Safety Climate-50 (KKB-50)

Abstract

This article presents the results of works on a shortened version of Questionnaire of the Safety Climate. Safety climate is treated as the sum of the employees’ moral perceptions of their work environment. It reflects employees’ perceptions of organizational management system including policies, practices and procedures. The shortened version of Questionnaire of the Safety Climate contains 50 statements that create 10 dimensions: employees’ participation in safety matters, safe behaviours, management commitment, modeling and strengthening of safe behaviours in the organization, risk management in case of an accidents, technical facilities and ergonomics, work pace and the level of fatigue , the process of health and safety trainings, workplace atmosphere, organization policy in the field of occupational health and safety management. The research was conducted in a group of 813 people. Preliminary analyzes indicate satisfying psychometric properties, and thus – KKB-50 can be considered as a valid and reliable tool for measuring the safety climate in an organization. The value of Cronbach's alpha coefficient for the global dimension of the safety climate was 0.930, while for its individual scales it fluctuated within 0.67-0.83. The accuracy of the questionnaire estimated using the linear correlation coefficients r-Pearson is on a good level (r = 0.84, p < 0.01). Factor analysis confirms the homogeneity of scales.
