Psychologists study human behaviour and the processes associated with how people think and feel, conduct research and provide treatment and counselling in order to reduce distress and behavioural and psychological problems. They promote mental health and positive behaviour in individuals and groups. Psychologists work on a broad range of issues with clients, including children, adults, couples, families and organisations.

Art therapists work with a client or a group of clients to help them address emotional and psychological issues through creative activities such as drawing, painting, sculpting and collage.

Psychiatrists diagnose, treat and try to prevent human mental, emotional and behavioural disorders. Psychiatrists should not be confused with psychologists, whose training does not include a medical degree and who do not have the authority to prescribe medicines.
