As global aging accelerates, cognitive decline among older adults increasingly impairs their ability to perform instrumental activities of daily living, essential for independent living. While traditional cognitive training is effective, it faces logistical barriers, and computer-based interventions vary in accessibility and efficacy. There is a notable research gap in applying semantic cognitive strategies—techniques leveraging meaningful associations—to support everyday functioning in older adults. This pilot randomized controlled trial evaluated the feasibility, acceptability, and effects of the Semantic Cognitive Training (SCT) program, which uses semantic-based cognitive strategies targeting instrumental activities of daily living, delivered via flexible, computer-based training for older adults in Hong Kong. Fourteen healthy older adults were randomly assigned to either the SCT or cognitive stimulation program (control), both lasting nine weeks. Feasibility was assessed by retention, attendance, and completion rates. Acceptability was measured via post-program surveys. Outcomes on independent living, cognitive function, and quality of life were evaluated pre- and post-intervention. Full retention, attendance, and completion rates demonstrated feasibility. SCT participants showed faster completion times, suggesting improved processing efficiency. Acceptability ratings were high overall, with SCT scoring higher in clarity but slightly lower in satisfaction than control. Trends indicated cognitive improvement, though not statistically significant. Despite the small sample size, the SCT program was feasible and acceptable. Larger studies are needed to confirm these findings and assess applicability to broader older adult populations, including those with cognitive impairment.
