Psychological Impacts of COVID-19 On Canadians
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.

Covid-19 Vaccine Hesitancy among Canadians
Overall this research explores the prevalence, correlates, and drivers of COVID-19 vaccine hesitancy in the Canadian population.
The three goals of this research were to 1) investigate the prevalence of COVID-19 vaccine hesitancy and rejection; 2) examine demographic, health-, and employment-related correlates of vaccine hesitancy; and 3) examine qualitative drivers of vaccine hesitancy among the Canadian population.

Neuropsychological Consequences of Long-COVID
The aim of this research is to understand the neuropsychological symptoms experienced by individuals with Long-COVID. With these findings, we hope to contribute to the development of interventions and supports available to impacted individuals.
Our goals are to 1) establish consistent definitions and core outcomes of Long-COVID 2) establish valid diagnostic and prognostic tools, 3) characterize subtypes and phenotypes of Long-COVID , 4) develop national recommendations for rehabilitation pathways for persons with Long COVID, 5) determine the feasibility of virtual care solutions (in particular, Cogniciti’s Brain Health Assessment) at addressing cognitive symptoms.

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.

Graduate Research

Well-being and Cognitive Status as Moderators of the Association Between Parkinsonism and Cognitive Function
Investigating Graduate Student: Allison Chung
Alison’s study investigated the modulating role of psychological well-being on parkinsonism and cognitive function. The results of this study found that there was no modulating influences of psychological wellbeing or cognitive status on the within-person coupling of parkinsonism and cognition. However, additional research is needed to further explore the role of psychological wellbeing on parkinsonism.
Honours Research

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.
