Medical psychology and psychiatry is the obligatory courses for five-year and seven-year medical students. With the rapid changes of society and continuous improvement of medical services , it is necessary to adjust and integrate the teaching content of these two courses. Teaching order of some chapters in the teaching syllabus was not helpful for students to understand the teaching content. Some teaching content was repetitive. Part of the self-study content urgently needs to teach with the development of the society and changes in disease spectrum. After the adjustment , the teaching content of the curricu-lum with strong pertinence was clear and coherent. It improved the teaching efficiency and knowledge of students;therefore, the curriculum is widely praised by the students.
