Cognition and Daily Interactions: The CADI Study
The goal of this study is to better understand the daily lives of older adults as this may
relate to the process of cognitive decline. We are trying to find ways to identify risk for Alzheimer’s disease in order to try to prevent it. The study is looking for adults between 55 and 70 years old who are having trouble remembering things lately. Your doctor may have told you that you have something called Mild Cognitive Impairment (MCI). To join the study, you’ll need to be comfortable reading and speaking English. To see if you qualify for the study, we first need to talk with you on the phone. This will take about 10-15 minutes and will help us figure out if you’re a good fit for the study.
If you join the study, here’s what will happen:
- You’ll visit our laboratory at Purdue University for a short time or schedule a Zoom meeting.
- We’ll ask you some questions about your memory and thinking skills.
- Depending on how well you do, we might ask you to fill out more surveys and have a conversation with us.
- For two weeks, you’ll need to take short surveys each day on a phone app or tablet. Don’t worry if you don’t have one, but being comfortable using a smart device is a requirement for the study.
- You will also play some brain games on your phone or tablet.

Parenting Stress and Relationships: PASAR Study
Are your kids under 5 years old? No older kids?
This study examines how daily parenting stress affects marital satisfaction. Romantic relationships are central to health and well-being, and parenting stress is a common challenge that can strain couples. Prior research shows that stress influences relationships, but little is known about how everyday parenting stress shapes satisfaction in real time. By collecting daily data, we aim to capture these moment-to-moment dynamics and test whether factors like arguments about children help explain the effect of stress on satisfaction, and whether couple-specific factors such as communication and perceived support help buffer or worsen stress effects. Insights from this study could inform interventions that support parents in managing stress and maintaining healthier, more satisfying relationships.
Participants will be asked to complete three surveys a day for 14 days. Surveys will be sent in the morning, late afternoon, and later evening, and will take participants about 10 minutes to complete.
