The purpose of this study is to evaluate an online platform -- the Living Memory Home for Dementia Care Pairs (LMH-4-DCP) for persons with dementia and their family caregivers to engage in reminiscence activities together and record meaningful memories.

The main aims of this study are:

• To evaluate the feasibility and acceptability of the LMH-4-DCP platform.
• To explore the potential for LMH-4-DCP to reduce feelings of pre-loss grief and enhancing relationship quality in dementia family caregivers and their care-recipients ('Care-Pairs')

Care pair participants will be asked to log-in to LMH-4-DCP and complete study activities three times per week for two weeks. Researchers will compare the intervention group to an attention control condition to see if LMH-4-DCP's use is associated with reduced feelings of caregiver pre-loss grief and improved care pair relationship quality at follow-up.

The goal of this randomized controlled trial is to evaluate the Living Memory Home for Dementia Care Pairs (LMH-4-DCP) web application, a dyadic online psychosocial reminiscence platform, to reduce feelings of pre-loss grief and improve relationship quality in individuals with dementia and their family caregivers ('Care Pairs').

The main aims of this study are:

• To evaluate the feasibility and acceptability of the LMH-4-DCP platform.
• To explore the influence of the LMH-4-DCP intervention on reducing feelings of pre-loss grief and enhancing relationship quality in the care pair

Caregiver participants randomized to the intervention condition will be asked to log-in to LMH-4-DCP and complete reminiscence activities three times per week for two weeks. Researchers will compare the intervention group to an attention control condition, which includes LMH-4-DCP use without reminiscence-specific features, to see if LMH-4-DCP's use is associated with reduced feelings of caregiver pre-loss grief and improved care pair relationship quality at follow-up.

Data collected for the LMH-4-Dementia Care Pairs study will only be shared after we have published the data addressing the study's specific aims. Intellectual property and data generated under this project will be administered in accordance with both Weill Cornell Medicine (WCM) and NIH policies, including the NIH Data Sharing Policy and Implementation Guidance. After publication of our main findings, access to databases and associated software tools generated and the code to create these tools under the project will be available for educational, research and non-profit purposes.

These data will be shared after we have published the specific aims of this study. Requests for the code used to create LMH-4-Dementia Care Pairs will be reviewed by the investigative team and shared once we have published the findings showing it is safe and therapeutic.

1) to use the data for research purposes only; 2) not to identify any individual participant; 3) to secure the data using appropriate computer technology such as password-protected servers and files; and 4) to return and/or destroy data after analyses are complete.
