Abstract: Despite continued recognition of the important effect of work stress on safety performance, the topic remains a neglected area of empirical investigation. The purpose of the current study is to explore the combined influence of work stress and social support on safety performance based on the Job Demands-Control-Social support Model. Specifically, it is to investigate the effect of challenge stressors, hindrance stressors, safety control, supervisor support, coworker support, and group descriptive norms and their potential interaction effect on safety performance. Methods such as interviews, questionnaires and experiment simulations will be used to explore the correlation or cause and effect relations among these variables. The results can contribute to the safety performance theories on one hand, and have significant implications for practical safety management, helping to improve individual and organizational safety performance in workplace on the other hand.

Key words: Safety performance, Work stress, Social support, safety control
