About Dr. Tegan Cruwys

Tegan’s research investigates how social relationships shape mental and physical health; work that is at the intersection of social, clinical and health psychology. Tegan is a recipient of the Australian Research Council Discovery Early Career Research Award, a registered Clinical Psychologist, and a Senior Lecturer teaching into the postgraduate professional psychology programs at The University of Queensland. Tegan completed a PhD in 2012 under the supervision of Professor Michael Platow, followed by a Postdoctoral Research Fellow with Professor Alex Haslam.

Tegan’s research investigates how our social relationships shape our mental and physical health. This work is at the intersection of social, clinical and health psychology. Tegan uses a social identity framework to address questions such as:

  • Why are strong social relationships important for preventing and treating depression?
  • How does stress influence changes in identity, and vice versa?
  • Can we develop treatments for mental illness that are more affordable and less stigmatising, especially for vulnerable members of the community?
  • Which social groups are more likely to influence health behaviours?
  • How can we make psychological therapy for mental illness more effective by incorporating social-psychological theories of social influence and group formation?
