Psychologist: General Overview
The term psychologist refers to an individual who has received a doctorate in psychology. Most states have laws preventing people who have not obtained a relevant doctoral degree in psychology from presenting themselves as a psychologist. Additionally, many states have laws preventing anyone who is not licensed from presenting themselves as a clinical psychologist. "Clinical Psychologist" is the type of therapist who has been trained primarily to work as a therapist in the mental health field.
Clinical Psychologist
Clinical psychologist are generally the mental health professionals with the most training in therapy, assessment, and diagnosis. This does not necessarily mean they are the best therapists or have the most expertise, just that they have the most training.
PsyD versus PhD Psychologists
Clinical psychologists can earn a PhD (doctorate of philosophy in psychology) or a PsyD (doctorate of psychology). The PsyD is a newer degree and generally is more focused on the practice of clinical psychology (therapy, assessment, and diagnosis). The PhD is generally seen as a broader degree that also focuses on training the psychologist to be a researcher. Psychologists with both degrees have been doctorally training in the practice of therapy, assessment, and treatment.
Can Psychologists Prescribe Medicine?
Historically, psychologists have not been able to prescribe medicine. Recently some states (Louisiana and New Mexico) have granted psychologists prescription privileges. However, not all psychologists in these states can prescribe. Generally, psychologists have to complete 2-years of additional training and supervision before they are able to prescribe medicine. There are some other settings, such as the military, where some psychologists can prescribe medicine. In most treatment settings, psychologists are not able to prescribe.
