Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
To be eligible for participation in LEAF 2.0, participants must identify as the primary family caregiver of someone with Alzheimer's disease or Alzheimer's-related dementia, and whose care recipient is not living in a care facility at the time of enrollment. "Primary family caregiver" is defined as the person who spends the most time caring for the individual with Alzheimer's disease in a non-professional capacity. Participants must also be able to speak and read English, live in the United States, be at least 18 years of age, and have access to a reliable Wi-Fi connection. Respondents are ineligible if they have already participated in a prior version of LEAF.
