Abstract

The purpose of this research was to investigate the relationship between leader-member exchange and voice behavior, with a focus on the mediating role of psychological empowerment among non-academic staff at the Faculty of Science, Chiang Mai University. Data were collected from all 194 non-academic staff members using a questionnaire comprising the Leader-Member Exchange Scale, Psychological Empowerment Scale, Voice Behavior Scale, and personal demographic items. The data were analyzed using both descriptive and inferential statistics to test the research hypotheses. The mediation effects were examined using the Process Macro (Model 4) developed by Hayes (2018). The findings indicated that leader-member exchange had a significant direct effect on voice behavior (p < .01) and a significant direct effect on psychological empowerment (p < .01). Additionally, psychological empowerment had a significant direct effect on voice behavior (p < .01). The mediation analysis revealed that psychological empowerment fully mediated the relationship between leader-member exchange and voice behavior among the non-academic staff at the Faculty of Science, Chiang Mai University.
