The REMINDER Program for Older Adults Supported by Residential and Daycare Facilities

Implementing DRR programs in RDFs presents several unique challenges, including participant diversity in educational levels, physical and cognitive health, motivation, and logistical constraints within institutional settings. A feasibility study is essential to identify and determine how to overcome these barriers. Specifically, this study explores acceptability, accessibility, adherence, and usability to optimize the REMINDER intervention for RDF settings. By addressing these practical concerns, the feasibility trial will ensure the intervention is effective and implementable, laying the groundwork for a successful full-scale RCT that meets the needs of older adults in RDFs (resulting in an adapted version, the REMINDER4Care). By creating an engaging and well-accepted tool, we look forward to amplifying the RDF tools available to reduce the risk of dementia in their residents. Objectives The primary objectives of this study were as follows: 1. To evaluate the acceptance rate of RDF and participants to join the research; 2. To determine the suitability of participant eligibility criteria by estimating feasible eligibility and recruitment rates; 3. To measure participant adherence and retention through attendance rates across all intervention sessions and trends over time; 4. To assess the feasibility of the REMINDER program in clinical settings, including its acceptability, accessibility, and usability. Secondary objectives included exploring preliminary changes in cognitive and psychosocial outcomes from baseline to post-intervention while acknowledging that the study was not powered to detect statistically significant effects.
