In this article, we have undertaken an exploratory analysis of the extrinsic and intrinsic factors affecting an employer’s safety motivation in the construction industry, and their correlation with firm size, management level, and perceived risk. We have employed a model based on previous research by Michael Wright for the Health and Safety Executive (UK). Methods: A sample of managers from 198 construction firms in Catalonia (Spain) were interviewed collecting relevant data. The exploratory factor analysis of this data detected two factors: extrinsic (prosecution, inspection, external pressure) and intrinsic (legal, responsibility, internal involvement). Confirmatory factor analysis did not rule out the presence of extrinsic and intrinsic factors (Wright), and the analysis with covariates (MIMIC model) showed significant positive relationships between extrinsic factors, management level, and perceived risk. It also showed a significant positive relationship between intrinsic factors and firm size. Conclusion: The aim of this study was to make a preliminary diagnostic of an employer’s safety motivation. Our findings indicate that it is possible to develop external motivators (advice from inspection bodies, union activities, publicity of prosecution records, etc.) that are addressed to top managers and to firms more exposed to risk.We have also found that it is possible to develop internal motivators by introducing experience modification ratings, social accounting, advertising in the mass media, and promotion campaigns, particularly among bigger firms. Our findings will be useful to government agencies, company managers, and consultants and may be adapted for use in motivating midlevel staff to adopt participatory intervention programs.
