Examination of the Feasibility, Acceptability, and Efficacy of the Online Personalised Training in Memory Strategies for Everyday (OPTIMiSE) Program for Older Adults: Results from a Single-Arm Pre-Post Trial
ABSTRACT
Background:
Memory strategy training for older adults helps maintain and improve cognitive health, but is traditionally offered face-to-face, which is resource-intensive, limits accessibility, and challenging during a pandemic. Online interventions, such as the Online Personalised Training in Memory Strategies for Everyday (OPTIMiSE) program, may overcome such barriers.
Objective:
We report on OPTIMiSE’s feasibility, acceptability, and efficacy.
Methods:
Australians ≥60 years, reporting subjective cognitive decline, participated in this single-arm pre-post online intervention followed by a 3-month booster. We examined feasibility (recruitment, attrition, data collection), acceptability (recommendation to others), and efficacy (goals, strategy knowledge and use, self-reported memory, memory satisfaction and knowledge, mood).
Results:
Results:
OPTIMiSE was feasible, as demonstrated by strong interest (633 screened) and satisfactory level of attrition (51%). It was acceptable, with 97% agreeing they would recommend OPTIMiSE. It was efficacious: linear mixed-effects analyses revealed improvement across all primary outcome measures, with effect sizes in the moderate to large range [(d = post-course; 3 month booster; all P < .001): memory goal satisfaction (d = 1.24; 1.64), strategy knowledge (d = 0.67,0.72) and use (d = 0.79, 0.90), self-reported memory (d = 0.80; 0.83), memory satisfaction (d = 1.25; 1.29) and knowledge (d = 0.96, 0.26), mood (post course d = -0.35, non-significant at booster).
Conclusions:
This feasible, acceptable, and efficacious online intervention has the potential to enable access to an evidence-based memory intervention for older adults worldwide. This is particularly important for supporting the growing number of older adults living with cognitive concerns.
