Legal scholars have psychological problems because they have been in an “abnormal environment” for a long time. Music therapy is a psychological intervention method based on musicology, medicine and psychology. Therefore, the study used music therapy to intervene and treat the psychological diseases of legal scholars.

In the study, 84 patients with psychological diseases in a hospital in a western city were randomly divided into group A (41) and group B (43) by using SPSS21.0 statistical software. Group A was the control group without intervention; Group B was the music group, which was intervened by music therapy. In the experiment, Pittsburgh Sleep Quality Index (PSQI) was used to quantitatively evaluate the sleep quality of patients. The experimental results are shown in Table 1.Table 1.

Sleep quality of patients in the two groups before and after the intervention

Before the intervention, the sleep quality score of group B was significantly higher than that of group A, 2.62 ± 0.57 points; After the intervention, the indexes of group B were lower than those of group A, with a total score of 8.44 ± 2.01, much lower than 10.28 ± 2.14 in group A. The experimental results show that music therapy can significantly improve the psychological diseases of legal scholars.

Legal scholars often suffer from psychological diseases due to long-term “abnormal environment”. The study used music therapy as an adjunctive treatment, and the results showed that music therapy could effectively alleviate mental and psychological diseases.
