Our Current Projects:

Cognitive Control & Vulnerability to Depression
Patients with depression often experience difficulties with thinking, which can remain even following depression improvement. The purpose of this study is to evaluate thinking difficulties across those with current depression, those with past depression, and those who have never been depressed, to help identify how thinking difficulties and depression are linked. This project is funded by a grant from the Canadian Institutes of Health Research and conducted in collaboration with researchers at the Centre for Addiction and Mental Health / University of Toronto, the University of Calgary, and the University of British Columbia.

We are currently working with collaborators at the Centre for Addiction and Mental Health and the University of Toronto on a meta-analysis of previously published research on the effect of depression on cognitive control biases. The meta-analysis will allow us to determine the magnitude of the effect and clinical and methodological variables that may influence the effect.

Stigma of Gambling Disorder

Fear of stigma is one of the most common reasons that individuals with gambling disorder report for not seeking treatment. The purpose of this research is to better understand beliefs that the general public holds about gambling disorder and factors that might influence stigma, to inform stigma reduction efforts.
