Workplace anxiety disorder has a negative impact on the mental health and work performance of employees in small and medium-sized enterprises. The research aims to explore the impact of establishing financial accounting management efficiency mechanisms on workplace anxiety disorder in small and medium-sized enterprises.

The study focused on small and medium-sized enterprise employees and divided them into an experimental group and a control group. The employees in the experimental group have established a financial accounting management efficiency mechanism, including standardized financial systems, clear accounting processes, and effective internal controls. The control group maintained traditional financial accounting management methods. The study used a questionnaire survey method to obtain data on employees’ workplace anxiety disorder scores, and used software Statistical Analysis Systems (SAS) for data processing and analysis.

The study found that the workplace anxiety disorder scores of the experimental group employees were significantly lower than those of the control group. The average anxiety score of the experimental group employees was 3.25, while that of the control group was 4.62. The t-test and analysis of variance were used to verify the statistically significant differences between the experimental group and the control group.

Results shown that small and medium-sized enterprises can significantly reduce workplace anxiety disorders by establishing financial accounting management efficiency mechanisms. Standardized financial systems, clear accounting processes, and effective internal controls can help alleviate employees’ anxiety.
