Psychoanalysis is a breakthrough theory and has been widely used in psychotherapy because of its profound understanding of human beings. However, due to its long cycle and high cost, it is not suitable for everyone, especially in the university where the consultation cycle is limited. Brief dynamic therapy is a treatment method based on psychoanalysis theory, which adjusts the treatment setting compared with classical psychoanalysis in order to adapt to shorter treatment period, and is more suitable for the practice of psychological counseling in colleges and universities. This paper introduces the assessment and intervention model based on short range psychodynamics, including the assessment of client basic information, cyclical maladapative pattern, therapeutic intervention. This model has been carried out in colleges and universities, and has achieved good results. It can provide reference for other psychological counselors or psychological teachers.
