Many professionals serve as psychotherapists, and it can be confusing to understand how their training and services differ. A clinical psychologist has a Ph.D. from a clinical psychology program, generally considered to be a strongly research-oriented program. This person will have conducted specialized research, produced a doctoral dissertation, and will also have a great deal of training in psychotherapy and psychological assessments. Other psychologists have Ph.D.’s awarded from counseling psychology programs or school psychology programs; in many cases these are quite similar to clinical psychology programs but they tend not to focus as strongly on research or on psychological testing and assessment. Still others have a Psy.D. degree, which is granted by a specialized psychological training institute (i.e., not a university) and focuses on clinical work to the near exclusion of research.
A psychiatrist, in contrast, becomes trained by going to medical school and therefore has an M.D. degree. In Texas, only an M.D. can prescribe medication. Some psychiatrists do conduct psychotherapy, but more and more, given the exploding array of pharmaceutical medications, many psychiatrists focus on medication prescription and management. It can often be very helpful for a client to work with both a psychologist (for therapy) and a psychiatrist (for medication).
Still other professionals provide psychotherapy. For example, a master’s degree in education, social work, or family therapy can provide the necessary training to become a licensed therapist (e.g., a Licensed Clinical Social Worker [LCSW] or Licensed Professional counselor [LPC]). Unlike psychologists, these professionals cannot do psychological testing and, unlike psychiatrists or other medical doctors, they cannot prescribe medications.
