Mental Health Practitioner Designations
As a service to the community, the OAMHP is providing the information below to help outline the differences between counsellors, consultants, psychotherapists and psychometrists.
Counsellor
A professional whose practice involves the primary function of informing, advising, guiding, educating, and coaching. The practice of counselling includes, but is not limited to, clinical, and mental health counselling. Incorporated in its mandate is guidance and education to individuals, families and/or groups.
Consultant
Any person who provides consulting services in the form of education and information to individual professionals, groups or organizations in the public or private sector.
Psychotherapist
Psychotherapists work with individuals, couples, families and groups to help them overcome a range of psychological and emotional issues. Psychotherapists use personal treatment plans and a variety of non-medical-based treatments to help them solve specific problems; or to treat mood disorders such as depression, OCD and anxiety.
Using talk therapy, they provide insight and use psychotherapeutic interventions to change distressing patterns of cognitions or behaviours that contribute to mood, anxiety or other problems. Some examples of the different approaches psychotherapists use are behavioural therapy, cognitive-behavioural therapy, and gestalt therapy. They commonly work in rehabilitation centres, multidisciplinary health clinics, psychological offices and in private practice. Although Psychotherapists may treat people with clinical diagnoses (e.g., Major Depression, OCD, General Anxiety Disorder) with psychotherapy (talk therapy), they are not licensed to provide a diagnosis or prescribe medication.
In Ontario, only members of the College of Registered Psychotherapists of Ontario (CRPO) have the authority to identify themselves as Registered Psychotherapists (RPs).
Psychologist and Psychological Associate
Psychologists and Psychological Associates are trained in the assessment, treatment, and prevention of behavioural and mental conditions. They diagnose neuropsychological disorders and dysfunctions as well as psychotic, neurotic and personality disorders and dysfunctions. In addition, Psychologists and Psychological Associates use a variety of approaches directed toward the maintenance and enhancement of physical, intellectual, emotional, social and interpersonal functioning.
A Psychologist or Psychological Associate may work with a variety of individual client populations such as children, adolescents, adults or seniors, or may focus their attention on families, couples, or organizations. They work in a range of settings including schools, hospitals, industry, social service agencies, rehabilitation facilities, and correctional facilities. Many Psychologists and Psychological Associates have their own private practice.
Only members of the College of Psychologists of Ontario may use the title ‘Psychologist’ or ‘Psychological Associate’; use the terms ‘psychology’ or ‘psychological’ in any description of services offered or provided, or hold themselves out to be a Psychologist or Psychological Associate.
Psychometrist
Psychometrists are part of research or healthcare teams that specialize in administering, scoring, analyzing and interpreting psychological tests. In Ontario, Psychometrists are not legally allowed to communicate diagnoses, so they must work under the supervision of a Registered Psychologist or Psychological Associate, who are licensed to do so.
Tasks include explaining testing procedures to clients, answering questions, administering tests, scoring tests, analyzing data, interpreting results, writing reports and communicating results to other mental health care professionals. A psychometrist must also stay up to date with new developments in the field, as tests and procedures are created, updated and/or improved.
Social Worker
From individuals and families to organizations and communities, social workers collaborate with their clients to address challenges through a process of assessment, diagnosis, treatment and evaluation.
Registered social workers have a specialized university education and must participate in continued professional learning and skills development to fulfil the requirements of their professional regulatory body.
In Ontario, in order to use the title Social Worker or Registered Social Worker or their French equivalents, or to hold out expressly or by implication that you are a social worker, you must be registered with the Ontario College of Social Workers and Social Service Workers.
