• Registration Number: NCT06733181
• Lead Sponsor: University of Coimbra

Brief Summary

Dementia and mild cognitive impairment (MCI) deeply impact individuals' well-being and are expected to increase due to population aging, with global cases projected to rise to 152.8 million by 2050. Social isolation, accounting for 4% of dementia cases, emerges as a critical modifiable risk factor, particularly in institutionalized older adults, where it significantly raises dementia risk.

To address these challenges, the REMINDER program was developed as a tailored, multidomain intervention to reduce dementia risk, emphasizing social and cognitive engagement and advancing its adaptation and evaluation in Residential and Daycare Facilities (RDF). To assess the feasibility of REMINDER in older adults supported by RDF (recruitment, adherence, retention, acceptability, accessibility, and usability) and explore potential changes in cognitive and psychosocial outcomes.

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
Feasibility outcomes (quantitative)	During the intervention (at the end of the sessions) and 1-week after the intervention	Retention
Feasibility outcomes (qualitative)	During the intervention (at the end of the sessions) and 1-week after the intervention	The intervention's usability (with Usefulness, Satisfaction, and Ease of use (USE) questionnaire) ranges from 8 to 56, with higher scores indicating greater usability.

Secondary Outcome Measures

Name	Time	Method
Preliminary efficacy data (Psychosocial/ Mental Health indicators)	Baseline and 1-week post-intervention	Life Satisfaction: This is measured using the Satisfaction with Life Scale (SWLS), scored from 5 to 25. Higher scores reflect greater life satisfaction.
Preliminary efficacy data (Cognitive functions)	Baseline and 1-week post-intervention	Verbal Initiative: Measured with the Verbal Fluency Test (letters M, R, and alternate category), scored by the number of correct words produced, with higher scores indicating greater verbal initiative.
Preliminary efficacy data (Perceived and performance-based functional status)	Baseline and 1-week post-intervention	Functional capacity: This is assessed using the UPSA-2-PT (UCSD Performance-Based Skills Assessment - 2nd version), scored from 0 to 100 points, with higher scores indicating better functionality.
Preliminary efficacy data (screening)	Screening and 1-week post-intervention	Global cognition was assessed using Addenbrooke's Cognitive Examination - Revised (ACE-R), a scale with scores ranging from 0 to 100, where higher scores indicate better cognitive functioning.
