Anxiety disorders often involve excessive and persistent feelings of worry and fear, which develop to a peak in a short period of time. The etiology of anxiety disorder is complex, and its pathogenesis is not clear. Genetic factors are one of the important risk factors of anxiety disorder, and neurobiochemical factors, psychological factors and biosocial factors may lead to this disease. In order to explore more ways to intervene in psychological anxiety, the study introduced psychology into the short-term training course of watercolor painting, and analyzed its influence mechanism and effect on psychological anxiety of adult students.

Forty-six adult students with psychological anxiety in a painting training course were randomly divided into the experimental group and the control group. The experimental group participated in the watercolor painting training course from the perspective of psychology. Symptom self-rating Scale SCL-90, social anxiety scale LSAS and Hamilton anxiety Scale HAMA were used for assessment before treatment, the second, fourth and eighth weeks after treatment, respectively.

The scores of HAMA, LSAS and SCL-90 in the experimental group after receiving painting training from the perspective of psychology were lower than those before participation (P<0.05), and the differences were statistically significant.

The short-term painting training course from the perspective of psychology has a positive effect on the psychological anxiety of adult students, which can maintain attention for a long time, improve the quality of sleep, and avoid the anxiety of nervousness or excessive thinking.
