Background

John McGrath AM, MBBS, MD, PhD, FRANZCP, FAHMS

John McGrath is a psychiatrist interested in discovering the causes of serious mental disorders. He is the Director of the Queensland Centre for Mental Health Research and conjoint Professor at the Queensland Brain Institute His research aims to generate and evaluate nongenetic risk factors for schizophrenia. He has forged productive cross-disciplinary collaborations linking risk factor epidemiology with developmental neurobiology. For example, John and his colleagues have made discoveries linking prenatal vitamin D and later risk of mental illness in the offspring. In addition, John has supervised major systematic reviews of the epidemiology of schizophrenia. He was awarded a John Cade Fellowship by the Australian National Health and Medical Research Council. In 2016 he was also awarded a Neils Bohr Professorship by the Danish National Research Foundation.

Research interests

  • The association between vitamin D status and brain outcomes

    In collaboration with Darryl Eyles, we are measuring early life vitamin D status and exploring if this changes the risk of later developing serious mental illness. These studies are in collaboration with colleagues in Denmark, Sweden and the Netherlands.

  • The demographic and clinical correlates of psychotic-like experiences

    Using two large surveys conducted in Australia in 1997 and 2007, our group have undertaken a suite of studies designed to understand the clinical relevance of isolated psychotic-like experiences. Over recent years we have published many papers on this topic, and have made important contributions with respect to how psychotic-like experiences are associated with (a) an increased risk of later psychotic disorders (based on the MUSP study), (b) depression, anxiety and substance use disorders, (c) a family history of mental illness, (d) exposure to trauma, (e) an increased risk of suicidal ideation and behaviour, (f) general physical health, and (g) help-seeking.

  • The Survey of High Impact Psychosis (SHIP)

    Our group was one of seven sites involved in the design and administration of the second Australian Survey of psychotic disorders. In collaboration with a large national team, we continue to explore key issues related to the needs of people with psychosis in Australia.

Research impacts

The Epidemiology team are interested in the frequency measures related to serious mental disorders (e.g. incidence, prevalence, mortality, recovery/remission). We are also interested in the clinical and demographic correlates of adverse mental health outcomes – some of these may be modifiable risk factors and thus important from a public health perspective. We use large, community-based surveys, and birth cohorts. Our focus has been on psychotic disorders and psychotic-like experiences in the general population. In addition, we are examining the links between early life vitamin D status and risk of later mental illness, by directly measuring vitamin D (in collaboration with Darryl Eyles and many international collaborators).
