Abstract
This article presents and tests a group-level model of safety climate to supplement the available organization-level model. Climate perceptions in this case are related to supervisory safety practices rather than to company policies and procedures. The study included 53 work groups in a single manufacturing company. Safety climate perceptions, measured with a newly developed scale, revealed both within-group homogeneity and between-groups variation. Predictive validity was measured with a new outcome measure, microaccidents, that refers to behavior-dependent on-the-job minor injuries requiring medical attention. Climate perceptions significantly predicted microaccident records during the 5-month recording period that followed climate measurement, when the effects of group- and individual-level risk factors were controlled. The study establishes an empirical link between safety climate perceptions and objective injury data.
