Derek M Hutchinson, Stephanie A Andel, Paul E Spector
We combined three independent streams of workplace climate research, safety, violence prevention, and civility, to devise a general safety climate scale that explicitly addressed a variety of risks. A confirmatory factor analysis suggested that a higher-order factor may be responsible for the similarity in relationships across these safety-related climate measures with exposure to organizational hazards and resulting employee outcomes. As a result, a concise 10-item measure was developed and validated to assess a possible general safety climate factor...
