The allocation of power in universities has a direct impact on students’ mental health, and whether the allocation of power is reasonable or not can lead to mixed depression symptoms in students’ learning process. Mixed type depression usually not only has symptoms of depression, but also is accompanied by manic symptoms. The fundamental way to improve the internal governance structure of universities is to establish a power balance mechanism, effectively ensuring the balanced allocation of students’ political, academic, and democratic power, and forming a scientific and reasonable power structure.

The study selected 50 students respectively from two universities as the research subjects, divided into an experimental group and a control group. The experimental group conducted a balanced allocation of internal governance structure, while the control group adopted traditional management methods. The depression status of two groups of students is compared and analyzed after one month of intervention.

The study used Excel 2010 and SPSS 23.0 to organize and analyze the data. The results showed that there was no significant difference in mental health indicators between the experimental group and the control group before the power allocation reform (P>0.05), and after intervention, the values of mental health indicators in the experimental group were significantly higher than those in the control group (P<0.05).

According to the results, it can be seen that the internal power allocation in universities has a certain impact on the mixed depression of college students, and after replanning and rational allocation, the psychological health status of college students can be significantly improved.
