The Influence of Psychological Safety on Employee Voice in Vietnam:Job Crafting as Mediator

Abstract

None

Vietnam's cultural values emphasize respect for authority and harmony within hierarchical structures. The study employed a quantitative research design, utilizing data collected from a diverse sample of employees across various industries in Vietnam. The research framework integrates psychological safety, job crafting, and employee voice, proposing that psychological safety positively influences employee voice directly and indirectly through job crafting. To test these hypotheses, a series of statistical analyses were conducted using SPSS and MPlus software, Confirmatory Factor Analysis (CFA), descriptive statistics, Pearson correlation and hierarchical regression analysis. Psychological safety was found to have a significant positive relationship with employee voice and job crafting, indicating that employees who perceive their work environment as psychologically safe are more likely to engage in voice and job crafting behaviors. Additionally, job crafting was positively related to employee voice, suggesting that employees who actively shape their job roles are more likely to express their ideas and concerns. Most importantly, the mediation analysis confirmed that job crafting partially mediates the relationship between psychological safety and employee voice, highlighting the role of job crafting as a mechanism through which psychological safety translates into increased employee voice. These findings have significant practical implications. Theoretically, the study extends the understanding of the antecedents of employee voice by integrating psychological safety and job crafting into the existing framework. Future research could build on these findings by exploring other potential mediators and moderators in different cultural and organizational settings.
