Researchers in various studies looking for participants

Study on preferences of potential users of continuous melatonin monitoring device to support sleep health

Researchers are conducting a study to understand the needs and preferences of the potential users of a continuous melatonin monitoring device to support sleep health. Individuals may be eligible to participate in this research if they:

• Are 18 years or older,
• Experience sleep problems, and
• Have been diagnosed with any of the following:
  • an endocrine disorder (e.g., diabetes, hyperthyroidism, adrenal insufficiency)
  • past traumatic brain injury affecting sleep health (but not experiencing current acute symptoms)
  • a chronic pain condition (e.g., fibromyalgia, rheumatoid arthritis, Ehlers-Danlos syndromes), and/or
  • a mood disorder (e.g., major depression, bipolar).

Researchers want to talk to the prospective user base early in the design process, as they believe it this is important to ultimately designing an effective and usable device. Participation in this study would involve completing two interviews with the first lasting 50-60 minutes and the second lasting 60-90 minutes (total estimated time commitment of about 2.5 hours). During the second interview, participants will be shown potential app designs and provide their feedback. Participants will receive $30 Amazon gift cards for each session and can receive up to $60 if they complete both sessions.

Individuals interested in participating should fill out this online form to confirm eligibility.

Individuals will be able to review the consent form for this study if they meet the eligibility criteria prior to any information being collected.

Individuals with aphasia needed for study

The Purdue Aphasia lab invites people with aphasia to participate in a new NIH-funded training study. Participation will help researchers to better understand language recovery in aphasia, in hopes to develop new language treatments.

To be eligible, individuals should have aphasia as a result of a stroke, have no history of other neurological conditions (dementia, Parkinson’s disease, etc.) and be a native speaker of English. Eligibility for this training study will be determined after the initial language evaluation.

Studies will be conducted at Lyles-Porter Hall, at the Indianapolis lab site or virtually via Zoom. Participants, if eligible, will be compensated $20 per session, and free garage parking is provided.

The principal investigator is Jiyeon Lee, associate professor in the Department of Speech, Language and Hearing Sciences. For more information, contact aphasia@purdue.edu, call 765-496-0216, or visit the Aphasia Research Laboratory website. IRB-2021-659.

Study on High Intensity Interval Training (HIIT) and mindfulness activity on cognition

Young adults ages 18-30 are needed to participate in a research study on how cognitive changes occur as a result of HIIT and mindfulness activity. 

Participants will be compensated $45 total for completing the study. Participation requires one visit to the Lambert Fieldhouse. The visit may last 2.5-3 hours, involving questionnaires, computer games, interval exercise and assessment of brain activation (i.e., electroencephalogram [EEG]).

For more information, contact the Physical Activity and NeuroCognitive Health Lab at panchlaboratory@purdue.edu in the Department of Health and Kinesiology. Professor Shih-Chun Kao in the Department of Health and Kinesiology is the principal investigator. IRB-2022-1416.

Studies looking for Asian and multiracial individuals and families

Researcher in the Antiracism, Resistance, Identity, Socialization, and Equity (ARISE) Lab study how talking about race, ethnicity and culture impacts identity development and mental health.

Researchers are recruiting:

• Multiracial/biracial/mixed race youth and adults.
• Parents of multiracial youth.
• Asian American youth and adults.

By filling out this short 1–3-minute survey, individuals can be added to the lab’s email list. They will have the option to sign up for newsletters that will share resources, an advice column and fun features like pop culture news and recipes from their community that are family-friendly. Individuals can also sign up for the lab’s participant pool to receive invitations to ongoing studies.

Participation in studies would involve tasks such as completing brief and potentially compensated anonymous surveys or interviews to share personal experiences and perspectives so researchers can learn more about multiracial and Asian American youth and families.

Questions can be directed to Annabelle Atkin, principal investigator and assistant professor of human development and family science, at ariselab123@gmail.com. IRB-2023-249.

How children think and feel during and after exercise 

Children ages 8-10 are needed for a research study on how children think and feel during and after exercise.

Participation in this study requires two visits on separate days to the Physical Activity and NeuroCognitive Health (PANCH) Laboratory in Lambert Fieldhouse. The first visit may last approximately three hours and involve computer games and a fitness test. The second visit may last about three hours and involve health-related and demographic questionnaires, two sessions of 20-minute aerobic exercise, and recoding of brain waves using techniques such as electroencephalogram (EEG). Participation in this study will be compensated by a maximum total of $100.

Shih-Chun Kao, assistant professor in the Department of Health and Kinesiology, is the principal investigator. To participate or for more information, email panchlaboratory@purdue.edu or call 765-496-7781. IRB-2021-955.
