One of the most popular fields of psychological study is child psychology. As a child psychologist, you will be working directly with children of all ages who have emotional disorders, substance abuse issues, and family problems. It will be your role to properly diagnose and treat these children. With an increased awareness of mental health concerns for children, there will be a growing demand for qualified psychologists at all levels of schools, mental health facilities, hospitals, and many government agencies. A starting child psychologist can earn around $40,000 annually.
