戴口罩在组织情景中对员工的心理安全感和建言行为有影响。本研究通过情境问卷实验，采集了291名在职员工的戴口罩行为对建言行为的影响作用及机制，并探讨了心理安全感的中介作用和威权型领导风格的调节作用。研究发现：（1）戴口罩能够通过增强员工的心理安全感，从而正向预测员工的抑制性建言行为，但对促进性建言影响不显著；（2）威权型领导风格调节了员工戴口罩与心理安全感之间的正相关关系，威权型领导风格的水平越高，其正相关关系越强。（3）心理安全感在戴口罩行为和建言行为之间存在着遮掩效应。遮掩效应的发现说明戴口罩不是引起员工建言的直接因素，而是对于那些缺乏心理安全感而沉默的员工来说，戴口罩的心理保护作用会让他们表现出更多的建言。研究结果丰富了戴口罩效应和建言行为的相关研究，为管理实践提供了促进建言行为的借鉴意义。

Wearing masks has an impact on employees' psychological security and voice behavior in organizational situations. In this study, the effects and mechanisms of the mask-wearing behavior on voice behavior of 291 employees were collected through a situational questionnaire experiment, and the mediating role of psychological security and the moderating role of authoritarian leadership style were explored. The study found that: (1) wearing masks can positively predict employees' inhibitory voice behaviors by enhancing employees' psychological security, but has no significant effect on promoting voice behaviors; (2) Authoritarian leadership style moderates the positive correlation between employees wearing masks and their psychological security. The higher the level of authoritarian leadership style, the stronger the positive correlation. (3) Psychological security has a masking effect between wearing masks and voice behavior. The discovery of the masking effect shows that wearing masks is not a direct factor for employees to give voice, but for those employees who lack psychological security and are silent, the psychological protection effect of wearing masks will make them show more voice. The research results enrich the relevant research on the effect of wearing masks and voice behavior, and provide reference for management practice to promote voice behavior.
