On high-risk construction sites, frontline workers are constantly exposed to dual channels of safety communication: supervisory safety communication (SSC) and coworker safety communication (CSC). While existing research has emphasized the general importance of safety communication in promoting safety performance, the differentiated effects and psychological mechanisms of SSC and CSC remain underexplored. To address this gap, this study aims to adopt a Conservation of Resources (COR) theory framework to examine how SSC and CSC influence construction workers' safety behavior (SB) through psychological mechanisms, and how these effects vary under different levels of work pressure (WP). A survey was conducted with 359 frontline construction workers in large-scale projects across China, and data were analyzed by multiple linear regression and an interaction analysis with simple slopes. Results show that SSC (β = 0.234, < 0.001) and CSC (β = 0.545, < 0.001) both positively affect SB. Mediation analysis confirmed the roles of SKSE, SM, and POS, with SM showing the strongest effect (β = 0.235, < 0.001). WP was found to weaken SSC's effects but not CSC's. These findings advance COR theory by clarifying psychological resource pathways in safety communication. Practically, the study suggests differentiated strategies for leveraging supervisory and coworker communication to enhance safety under varying work pressures.
在高风险建筑工地，一线工人不断面临安全沟通的双重渠道：监督安全沟通（SSC）和同事安全沟通（CSC）。虽然现有研究强调了安全沟通在促进安全绩效方面的普遍重要性，但SSC和CSC的差异化影响及心理机制仍未得到充分探索。为填补这一空白，本研究旨在采用资源守恒（COR）理论框架，考察SSC和CSC如何通过心理机制影响建筑工人的安全行为（SB），以及这些影响在不同工作压力（WP）水平下如何变化。对中国各地大型项目的359名一线建筑工人进行了调查，并通过多元线性回归和简单斜率的交互分析对数据进行了分析。结果表明，SSC（β = 0.234， < 0.001）和CSC（β = 0.545， < 0.001）均对SB有正向影响。中介分析证实了安全知识自我效能感（SKSE）、安全动机（SM）和安全氛围感知（POS）的作用，其中SM的影响最强（β = 0.235， < 0.001）。研究发现，WP会削弱SSC的影响，但不会削弱CSC的影响。这些发现通过阐明安全沟通中的心理资源路径，推进了COR理论。在实践中，该研究提出了在不同工作压力下利用监督和同事沟通来提高安全性的差异化策略。
