During my PhD within the Center of Cognitive Epidemiology, I received rigorous training in modern test theory, which included item response theory methodology that I now apply to health outcomes research, i.e., functional status, fatigue, and depressive symptoms in older adults. One primary research goal has been to increase the sensitivity of functional status measurement within the preclinical range of dementia. Meeting this goal has led to inquires related to content and construct validity, and the investigation into complex or advanced ADLs, as well as performance-based measures of functional status. A secondary goal relates to the construct of cognitive reserve, specifically, the potential to bolster reserve in older adults. With regard to this later goal, I’m interested in epidemiologic investigations into cognitive leisure or enrichment activities, or cognitive stimulation in experimental models
