With the rapid development of society, the probability of criminal incidents among college students is gradually increasing, leading to an aggravation of social barriers among college students. Therefore, legalized management of universities has become an important method for building a harmonious campus.

To provide effective psychological guidance for students’ social disorders caused by the increase in crime rates in universities, this study selected 150 students from a certain university to conduct a social disorder questionnaire survey targeting the crime rate in universities and filled out the Hamilton Depression and Anxiety Scale (HAMA). Then, a one-semester rule of law management was adopted for the university, and after the experiment, a social disorders questionnaire survey and HAMA scale were conducted again on the 150 students.

The experimental results showed that before the start of the experiment, a total of 135 students developed anxiety due to the increase in crime rates in universities. Among them, 76 were mild, 51 were moderate, and 8 were severe, with a HAMA score of 52.4 ± 3.1. After the experiment, the number of people who developed anxiety due to the crime rate in universities decreased to 114, among which 81 were mild, 30 were moderate, and 1 was severe. The HAMA score decreased to 43.5 ± 2.6. The number of anxious individuals and HAMA scores have decreased to a certain extent after the experiment.

Legalizing the management of universities can alleviate students’ social disorders caused by university crimes and provide good psychological guidance for students.
