Psychologists employ a research-oriented approach in their practice, by formulating hypotheses, and testing hypotheses through the collection of data. Psychologists assist in improving people s functioning through the application of a wide set of skills and knowledge, in conjunction with scientifically established findings. Psychologists conduct assessment, diagnosis, prevention, and treatment of problems at an individual, group, organisational and community level. Psychologists do not prescribe medication, as they do not have the necessary pharmacological training in this area. Rather, psychologists treat disorders from a variety of other perspectives that encompass environmental, social, cognitive and behavioural factors.
Psychiatrists work from a medical background.
They need to complete a medicine degree, followed by postgraduate study in psychiatry. Psychiatrists engage in the inspection of medical history, examination, diagnosis and treatment of mental, emotional and behavioural disorders. Psychiatrists work from a bio-chemical perspective. This provided them with the necessary skills in the pharmacological area. This training and knowledge allows them to prescribe pharmacological medication to clients for the treatment of disorders.
