不安全行为信息在建筑工人群体中的传染机制

Contagion mechanism of unsafe behavior information in groups of construction workers

为探究不安全行为信息在建筑工人群体中的传染路径与影响效应,根据社会信息加工理论、计划行为理论和社会传染理论,在文献研究的基础上,通过理论假设,构建以工友不安全行为信息为自变量,以行为态度、主观规范和感知行为控制3种行为认知因素,以及不安全行为意向为中介变量的建筑工人不安全行为信息传染机制理论模型。通过开发测量量表、编制调查问卷收集数据,基于271个有效样本,利用验证性因子分析与结构方程模型建模分析方法实证检验理论模型。研究结果表明:工友有意不安全行为和工友不安全沟通行为通过6条传染路径诱发新的不安全行为;相较于工友不安全沟通行为,工友有意不安全行为作为传染源时的传染效应更强;管理者通过控制传染信息源和弱化传染媒介可有效抑制不安全行为信息在建筑工人群体中的传染效应。

In order to explore the contagion mechanism and effect of unsafe behavior information in groups of construction workers,a theoretical model of the contagion mechanism of unsafe behavior information among construction workers was constructed based on social information processing theory,theory of planned behavior,and social contagion theory.In this model,information about workmates'unsafe behaviors was served as the independent variable,and behavioral cognitive factors(i.e.behavioral attitudes,subjective norms,and perceived behavioral control)and unsafe behavioral intentions were served as mediating variables.Through developing measurement scales and creating questionnaires to collect data,the theoretical model was empirically tested based on 271 valid samples using the analysis methods of confirmatory factor analysis and structural equation modeling.The results show that workmates'intentional unsafe behaviors and workmates'unsafe communication behaviors can induce new unsafe behaviors through six contagious pathways.Moreover,as a source of contagion,the contagion effect of workmates'intentional unsafe behaviors is greater than that of workmates'unsafe communication behaviors.Managers can effectively control the contagion effect of unsafe behavior information among construction workers by controlling contagion information sources and weakening infectious media.
