Interindividual and intraindividual variability in amnestic mild cognitive impairment (aMCI) measured with an online cognitive assessment
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.
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.
mHealth App Use and Outcomes in Canadians
Principle Investigator: Dr. Theone Paterson
The goal of this research is to improve understanding of how Canadians use diet and physical activity mobile applications (‘mHealth apps’) available on the Canadian market to aid in achieving personal health goals. The gap between our goals and our behaviours has been termed the intention-behaviour gap.
We aim to 1) learn from users what it is about mHealth apps that help them achieve goals, 2) increase our understanding of who is using mHealth apps to achieve their goals, 3) examine relationships between person-centered, interpersonal, app-related factors, and peoples’ use and success using these apps, and finally, 4) explore individuals’ maintenance of goal behaviours.
