Psychologist
A
psychologist is a scientist and/or clinician who studies
psychology, the systematic investigation of the human
mind, including
behavior and
cognition. Psychologists are usually categorized under a number of different fields, the most well-recognized being clinical psychologists, who provide
mental health care, and
research psychologists, who collect, investigate and analyze aspects of human behavior.
In the professional world 'psychologist' has two meanings. In the broadest of these two meanings, psychologist refers to anyone with an advanced degree in clinical psychology, counseling, industrial psychology, educational psychology, or one of several other subfields, and who makes professional contributions based upon that training, be it as a therapist, counselor, researcher, teacher, or consultant. This sense of the word is independent of licensing.
The narrower sense of the word 'psychologist' refers to licensing and to a legal context. In the United States and Canada, 'psychologist' is a protected professional title. In this sense, the title of psychologist means that the mental health professional has a doctoral degree (usually a Ph.D., Psy.D., or Ed. D.) in clinical, counseling, industrial, or eductional psychology and has also met state or provincial licensing criteria. Those criteria typically include a period of post-doctoral practice under the supervision of a licensed psychologist, a licensing exam, and continuing education requirements. In most states in the United States and in most provinces in Canada, only licensed psychologists, licensed therapists (like Marriage and Family Therapists) and psychiatrists can legally provide psychotherapy and use this term to refer to aspects of the mental health treatments they perform. Most states exempt from licensing school psychologists who practice within employment by a school district - such psychologists must be certified by their state or province department of education.
Licensing bodies also grant legal status under titles other than 'licensed psychologist', such as 'Marriage and Family Therapist', 'psychiatrist' or 'Substance Abuse Counselor'.

Like psychiatrists, licensed psychologists hold a
doctorate in their field. Psychiatrists are
physicians who have earned an
M.D. or a
D.O., whereas licensed psychologists have earned a
Ph.D.,
Psy.D., or
Ed.D. In addition, each of these two licenses operate under somewhat different legal definitions and restrictions.
Psychologists are often categorised under different fields or disciplines.
Clinical psychologists
Clinical psychologists and counseling psychologists often work in
clinics, counseling centers,
hospitals and private practices. They diagnose and evaluate mental and emotional
disorders, and use tools such as cognitive-behavioral and interpersonal psychotherapy and hypnosis to treat patients. They conduct interviews and psychological tests, and may conduct complex treatment programs, sometimes in conjunction with
physicians or other medical
specialists. There are specialties within the field of clinical psychology depending on the focus in clinical medicine, including psychopathology, counseling, neuropsychology, medical psychology, clinical health psychology, and forensic psychology.
Medical psychologists
Medical psychologists are specialists in psychological and behavioral aspects of physical illness and have additional advanced training in psychopharmacology, physiology, and rehabilitation. Their clinical tools include assessment in general and specialist medicine (e.g., chronic illness management, pain treatment, brain injury), clinical psychophysiology (eg, biofeedback), psychotherapy, hypnosis, behavioral medicine, and psychosocial interventions; they are licensed to prescribe medication in certain countries. They tend to work in hospitals and private practice. The specialty is not recognized in all countries.
Health psychologists
Health psychologists are of two general types: clinical health psychologists (similar to medical psychologists) and community health psychologists (who specialise in psychological and psychosocial aspects of health in the larger community). Clinical health psychologists are oriented to biopsychosocial aspects of physical health and illness and their field overlaps that of behavioral medicine to a large extent. Clinical and community health psychologists work in a number of different roles: clinical diagnosis of problems that relate to physical illness, psychological, psychophysiological, and psychosocial interventions; clinical communication; organisational design in medical care; health promotion; teaching and training; consultancy; giving advice on health policy. The clinical specialty is not recognised independently in all countries (e.g., New Zealand).
School psychologists
School psychologist work in schools, state departments of education, hospitals, clinics and universities. They are primarily interested in applying psychological knowledge to the resolution of schooling and learning problems. They provide consultation to teachers, administrators, and parents; assessment of students (including assessment of disabilities requiring special education); intervention services; in-service education for staff; family intervention; program evaluation; and research.
Organizational psychologists
Organizational psychologists are concerned with the performance of people at work and in training, with developing an understanding of how organisations function and how individuals and groups behave at work. Their aim is to increase effectiveness, efficiency and satisfaction at work. This specialty can be highly lucrative.
Research Psychologists
Research psychologists study
behavioral processes by
experimenting on human beings and
animals. They work in universities and private research centers, as well as for government organizations and often contribute to fields including
marketing,
design, and different forms of
drug and
chemical research. Common areas of research include
memory,
motivation, and factors affecting behaviour and
development.
Licensed psychologists generally have academic doctoral degrees (
Ph.D.) that are different from the professional degrees of physicians in that they require not only coursework, supervised professional training, and clinical internship but also significant academic research experience and original contributions to scientific research in the form of a
dissertation. In this sense, the Ph.D. in professional psychology is a hybrid academic/professional degree, and university programs in professional psychology are not only academic but also training programs typically characterized by rigor and intensity. Some psychologists have professional degrees in psychology (
Psy.D.) that include similarly rigorous coursework, supervised professional training, internship, and developing the ability to read and interpret academic research, but they do not necessarily require original research contributions to science (although many of these professional programs require an academic dissertation or an equivalent project).
Within Australia the title 'psychologist' is also restricted by law. Use of the title is reserved for individuals registered with their States Psychologist's Registration Board, which requires a four year bachelors degree and either two years of further acredited study or two years of supervised work. These restrictions apply to all who want to use the title 'psychologist' in any of its forms.
In New Zealand, the use of the title 'psychologist' is restricted by law. Initially, only 'clinical psychologist' and 'registered psychologist' were restricted (to people qualified as such). However, in 2004, the use of psychologist is now limited to only those registered psychologists (including clinical psychologists). This is to prevent the misrepresentation of other psychology qualifications in the mental health field. Academic psychologists (e.g., social psychologists) are now only able to refer to themselves as 'researchers in psychology'.
In the UK the use of the title "chartered psychologist" is protected by law. However use of the term 'psychologist', 'psychotherapist' or 'therapist' is not. This can create confusion and varying quality of service as many inadequately trained practitioners who are not chartered can establish practices and charge for services for which they are not properly trained.
Similar restictions apply in the United States, although application of these restrictions varies state-by-state. Most states include exemptions from licensing in order to use the title "psychologist" if they are teaching in universities, or if they are certified by the state's department of education as a school psychologist and are practicing psychology within the scope of their employment in a school district. In most states, self-employed psychologists offering services to the public, whether they are clinical, counseling, school, or industrial psychologists must be licensed, which usually requires an advanced degree, two years of supervised experience, and passing written and oral examinations. The licensing may carry the title of licensed psychologist, Marriage and Family Therapist, or some other title depending upon the state or province and the license involved.
Prescribing Powers
In some countries, pschyologists cannot obtain a license to prescribe
psychiatric medications. Prescription privileges in the United States have recently begun to change â€" e.g., in
New Mexico and
Louisiana.
