Clinical psychology is an area of psychology dedicated to understanding and preventing psychologically-based dysfunction and promoting subjective well-being. Health psychology is an area of psychology dedicated to understanding biological, psychological, and social factors that are involved in health, illness, and healthcare. The clinical and health psychology research group tests and develops psychological theory, as well as informs policy and practice. We investigate a range of research questions, including aetiology and treatment of nightmares, mild cognitive impairment and acquired brain injury, issues related to diet and eating, drug and alcohol consumption, gambling, autistic spectrum disorders, and workplace factors, such as long-term effects of shift work.
