The Cognitive Costs and Benefits of Social Technology use in Older Adulthood
Postdoctoral Research Fellow, Department of Psychology, College of Literature, Science & the Arts
Social engagement is an important protective factor for age-related cognitive decline and dementia. However, it is unclear whether social engagement through social technologies (i.e., texting, social media, video chat, email) demonstrate the same protective effects as face-to-face social interactions. The proposed study will assess whether previously-established social technology measures demonstrate measurement equivalence across younger and older adult populations and are psychometrically sound for use in older adults.
Surveying Older Populations using Video Communication Technologies
Research Professor, Survey Research Center, Institute for Social Research
Professor, Department of Psychology, College of Literature, Science & the Arts
This research project will examine data quality, participation, respondent experience, and costs in two promising but not yet widely deployed survey modes that use off-the-shelf video technology and are less costly than face to face (FTF) interviews: video-mediated (VM) interviews (live two-way communication via platforms like Skype) and video self-administered (VS) interviews, in which video-recorded interviewers ask the questions and respondents answer by typing or clicking. The project's comparisons will provide new insights regarding how these decomposable aspects of human contact affect behavior and experience in surveys, in particular, for aging populations.
Housing Context and Functional Health Among Lower Income Older Adults: The Mediating Role of Social Resources
Noah J. Webster
Assistant Research Scientist, Survey Research Center, Institute for Social Research
Housing characteristics and disability in later life are closely tied, but whether housing can positively influence functioning through social resources is unclear. Using data from the National Health and Aging Trends Study (NHATS), this pilot study will determine if and which social resources are a pathway through which housing is related to functional health in later life.
Measuring Alzheimer’s Disease in Arabic-Speaking Populations
Kristine J. Ajrouch
Adjunct Research Professor, Survey Research Center, Institute for Social Research
The incidence of mild cognitive impairment (MCI) and Alzheimer's Disease and Related Dementias (ADRD) is higher among many racial/ ethnic minorities, but rates among Arab Americans, who exhibit more cardiovascular and other risk factors than whites, are unknown. The first of its kind, this pilot study translates and validates established measures of cognition, function and behavior commonly used in MCI and ADRD diagnosis so they may be used with aging Arab Americans.

Vision Impairment, Participation and Subjective Wellbeing in Older Adults
Assistant Professor, Department of Ophthalmology & Visual Sciences, Medical School
Blindness and vision impairment affects 1 in 11 adults over age 65 in the United States. Among older adults, vision impairment is associated with loss of independence, decreased quality of life and increased morbidity and mortality. In this study, we explore the pathways through which vision impairment influences poorer subjective wellbeing and whether this association is mediated through participation or activity limitations.

Examining the Role of Housing Tenure and Health on the Aging Population in the U.S.
Assistant Professor, Health Behavior and Health Education, School of Public Health
This pilot study examines the relationship between housing characteristics and health among older Americans. Using the Health and Retirement Study, we hypothesize that, homeownership will have a protective effect over negative health outcomes in disinvested neighborhoods and that affordable housing and good housing conditions protect against negative health outcomes.

Chronic Diseases and Physical Functioning: Development and Validation of an ICD-coded Multimorbidity Index
Melissa Y. Wei
Assistant Professor, Department of Internal Medicine, Medical School
This pilot study uses patient-reported outcomes in the nationally-representative Health and Retirement Study and Medicare claims to develop and internally validate a multimorbidity index for International Classification of Diseases (ICD)-coded chronic conditions weighted to physical functioning. The study will yield a validated multimorbidity measure that captures the impact of coexisting chronic diseases on physical functioning in aging adults relevant for clinical care, research, and policy.

Cognitive Resilience to Depressive symptoms in Diverse Older Adults
Laura Beth Zahodne
Assistant Professor, Psychology, College of Literature, Science & the Arts
Faculty Associate, Survey Research Center, Institute for Social Research
Significant knowledge gaps regarding the depression-dementia link include modifiable factors that attenuate this link and reasons for differences in resilience across racial groups. This pilot addresses these gaps by recruiting a racially diverse, population-representative sample of older adults for psychosocial, cognitive, and functional assessment and by examining how modifiable psychosocial resources that differ across race promote cognitive resilience to depressive symptoms.

- Dr. Zahodne’s pilot resulted in initiating a new longitudinal cohort of adults transitioning into older adulthood: the Michigan Cognitive Aging Project (MCAP; PI Zahodne). MCAP has collected comprehensive measures of psychosocial functioning, health, and cognitive domains in over 400 racially and socioeconomically diverse adults assessed face-to-face. MCAP serves as a foundation for an ongoing longitudinal study that now includes the collection of blood-based biomarkers and neuroimaging data.

Muscle Weakness among Older Adults: A Silent Epidemic
Philippa J. Clarke
Research Professor, Survey Research Center, Institute for Social Research
Professor, Department of Epidemiology, School of Public Health
This pilot project charts new territory in investigating the long-term health consequences of dynapenia to: 1) predict whether individuals who fall below these proposed cut-points are at risk for developing future negative health outcomes; 2) examine proposed cut-points in predicting future health risks above and beyond traditional indicators of morbidity and mortality; and 3) understand the role obesity may play in exacerbating future negative health outcomes among those who are considered weak.

Demographic and Socioeconomic Differences in Polygenic Risk of Cardiovascular Health in the Health and Retirement Study
Postdoctoral Research Associate, Survey Research Center, Institute for Social Research
This pilot examines the extent to which polygenic scores (PGSs) are associated with cardiovascular risk factors (i.e. systolic and diastolic blood pressure, body mass index, smoking, and alcohol use) and how these associations are modified by key demographic (i.e. sex, age) and socioeconomic factors across the life course.
