Meditation or Health & Wellness Education Via Internet for Adults 50-80 Years Old

The primary aim of this research project is to evaluate whether an internet-based mindfulness meditation training improves cognition and resilience in stressed older adults. Dr. Oken specializes in evaluating the effects of stress on the human body, and he plans to use advanced statistical analyses to create a "multi-domain physiologic measure." This means study staff will collect biological data, including electroencephalogram (EEG, brainwaves), blood pressure, heart rate, breathing rate, and saliva samples. The investigator hypothesizes that when he statistically combines all of these together, he will have a measure that correlates with self-rated (survey) measures of resilience and stress.

Participants will undergo a telephone screening to determine eligibility, and then they will fill out online questionnaires before their Baseline Visit at the lab. Study staff will take physical measurements (i.e. height, weight, vision), administer short cognitive tasks that measure attention and memory, and collect biological data (listed above) during several different tasks. Some of the tasks are very simple, such as breath counting and listening to an audio recording of a podcast. And some of the tasks are intended to be more stressful, such as one that presents difficult math problems. The investigator hopes to induce stress so that study staff can measure resilience by evaluating how long it takes participants to return to a biological baseline, such as their usual blood pressure. In total, the visit is approximately 3 ½ hours long.

After the Baseline, participants are sent home with a handheld device that administers random 5-minute assessments, as well as tubes to collect saliva, for the seven days following the in-lab visit. Participants will also fill out short questionnaires about daily events over these seven days. Once data collection is complete, participants will come into the lab to return the device and samples and learn whether they have been randomized to receive the internet-based mindfulness meditation training (40% chance), an internet-based health \& wellness education program (40% chance), or a non-active waitlist (20% chance). All participants will be informed before the study begins that they will have access to the meditation and education materials once their participation is complete. Participants receiving the meditation and education will complete a one-hour online training each week for six weeks, and they will use an iPod to listen to guided meditations or educational podcasts (depending on group assignment) for 30-45 minutes per day. The iPod tracks their home practice, and they will return it at the end of the study. All participants will receive a weekly call from study staff to check in about whether they have experienced any health changes and, if applicable, how the meditation or education program is going.

Eight weeks after the Baseline Visit, participants will again fill out online questionnaires and come back to the lab for an Endpoint Visit, which is very similar to the Baseline. They will again collect saliva samples and complete assessments on a handheld device for two days following the visit. They will mail the samples and device back to the lab and then receive access to both internet-based training programs and associated audio recordings. Participants will then be asked to fill out online questionnaires one last time 6 months after the Endpoint Visit.
