At present, universities are facing the dilemma of students’ mental health demand and insufficient supply of counseling services. It is a general trend for university counselors to concurrently serve as psychological counselors. However, the practical confusion lies in the difference between the role positioning of university counselors and psychological counselors, which is easy to produce role conflicts in the four aspects of value, principle, relationship and method in the practice of psychological counseling, affecting the effectiveness of psychological counseling. This paper analyzes the connection between ideological and political education and psychological counseling, the commonality of the roles of university counselors and psychological counselors and the duality of the counselors engaged in psychological counseling, and shows the feasibility of the integration of the roles of the two. Counselors define the role boundary, avoid the double relationship, grasp the boundary of professional ability, improve the professional quality and practical ability of psychological counseling, promote the concept and technology of psychological counseling into the ideological and political work, can effectively promote the integration of roles and escort the physical and mental health of college students.
