There was no significant change in total depression score and depression index (P > 0.05). There were significant differences in social avoidance factors and social anxiety (P < 0.05), and there were relatively significant differences in the total score of sadness (P < 0.01). It is concluded that the use of artistic elements can effectively help people express themselves and express their psychological emotions, which has a certain effect in mental health treatment.
