Ageing Clinical Trial
Official title:
Modifiable Health Behaviors Associated With Time-of-Day Differences in Older Adults' Practice-Related Learning
This is a single-center, observational study design. Enrolled participants will be typically, healthy older adults. Participants will complete daily computerized measures, in addition to continuously wearing an Actiwatch device. The study period will last 2 weeks. The objectives of the study are to examine the impact of sleep, pain, and circadian rhythm on practice-related learning in older adults at their preferred versus nonpreferred times of day.
Participants will be asked to review the informed consent and consent to the study prior to
any study procedure.
There are four stages to this study: 1. a telephone interview, 2. an in-person interview and
completion of questionnaires, 3. an in-home single night sleep recording, and 4. two weeks of
computerized cognitive testing, subjective sleep and pain recordings, and wearing a
Actiwatch.
During the telephone interview, participants will be asked question about their age, sleep,
pain, and medical/mental health history. At a second visit, participants will complete a more
in-depth interview of their physical health, mental health, sleep, and pain history. They
will complete a brief test of their cognitive functioning. They will also complete 4
questionnaires about their time of day preference and mood. At the third visit, participants
will visit the University of Florida to be connected to a machine which will monitor their
sleep. Participants will return home to sleep while still connected to the machine and will
return the machine to the University of Florida the next day. Participants will complete
brief computerized daily questionnaires of sleep and pain and cognitive testing in the
morning and evening, and and wear an actigraph (wristwatch-like device) that measures arm
movements and ambient light for two weeks.
