Psychological Impacts of COVID-19 On Canadians

Collaborative Project 

This is a multi-wave study examining mental health, substance use, social support, social isolation, adherence to government guidelines (and more) through the use of online surveys and targeted interviews. Groups that may be disproportionately impacted by COVID-19 are of special interest in this study. 

Importantly, we are learning about coping of Canadians and plan to use this information in allocating mental health resources to those who need it most.

Interindividual and intraindividual variability in amnestic mild cognitive impairment (aMCI) measured with an online cognitive assessment

Collaborative Project 

Mean cognitive performance is worse in amnestic mild cognitive impairment (aMCI) compared to control groups. However, studies on variability of cognitive performance in aMCI have yielded inconclusive results, with many differences in variability measures and samples from one study to another.


The current study demonstrates that self-administered online tests can be used to remotely assess different types of variability in people at risk of Alzheimer`s. Our findings show small but significantly more interindividual differences in people with aMCI. This diversity is considered as ‘noise’ in standard assessments of mean performance, but offers an interesting and cognitively informative ‘signal’ in itself.

The Mental Health of Undergraduate Students and the Impact of COVID-19 

Investigating Honours Student: Jennifer Reeves

This study is looking to examine the mental health of undergraduate students, including the impact of self-care habits, hobbies, and COVID-19. Additionally, this study will examine how mental health fluctuates between the years of study. Previous researchers have found differing results in regards to the timing of peaks in distress, which this study hopes to address.

Early Caregiver Support and Type 1 Diabetes Distress in a COVID-19 Context

Investigating Honours Student: Taylor McEachnie

The purpose of this study is to improve the understanding of diabetes distress in emerging adults with type 1 diabetes (T1D) through its relationship to early caregiver support. In addition, it will investigate how diabetes distress interacts with the mental health impacts of COVID-19. The psychosocial experiences of type 1 diabetes are under-represented in research, so participation will serve to inform how mental health outcomes for emerging adults with T1D can be improved.
