Psychologists are registered mental health therapists with many years of training who apply their scientific knowledge and skills related to human behaviour and emotion to help people. They have practical and research skills to help in a wide variety of fields that include health, education and management. Clinical psychologists help with the diagnosis and treatment of mental illnesses across the lifespan. Most psychologists also help mentally healthy people to find ways of functioning better.

People with physical disabilities see psychologists for similar reasons that people in the wider community see them, the list is long. Some of the reasons include coping with day to day activities or a sudden change in activities, major health concerns, mental health and illness, understanding and coping with diagnoses, grief and loss, changes that happen during adolescence and preparing for and coping with what happens to an ageing body.
