The construction of a psychological backbone team plays an important role in improving the mental health of college students and maintaining campus safety and stability. At present, the research on psychological backbone mainly focuses on the construction of the training system, the problems existing in training, and the evaluation of training effects. There is less research on the specific setting of the course, that is, the teaching plan and teaching methods of the course. Therefore, this paper mainly explores the application of group painting psychological counseling in the psychological backbone training course of college students and how the psychological backbone applies group painting to carry out work in real life, on the one hand, it enriches the curriculum theory of group painting psychological counseling, and on the other hand, it points out ideas for practical work.
