Memory Strategy Training in Older Adults with Subjective Memory Complaints: A Randomized Controlled Trial.

Objectives: Subjective memory complaints (SMC) in older adults are associated with a decline in everyday functioning and an increased risk for future cognitive decline. This study examines the effect of a memory strategy training compared to a control memory training on memory functioning in daily life.

Methods: This was a randomized controlled trial with baseline, post-treatment, and 6-month follow-up assessments conducted in 60 older adults (50-87 years) with SMC. Participants were randomly assigned to either seven sessions of memory strategy training or seven sessions of control memory training. Both interventions were given in small groups and included psycho-education. Primary outcome measure was memory functioning in daily life. Objective measures of memory performance and self-reported measures of strategy use were included as secondary outcome measures.

Results: Participants in each intervention group reported an improvement in personal memory goals (p<.0005), up to 6 months after training. An interaction effect showed that participants following memory strategy training reported a larger improvement in personal memory goals (p=.002). Both intervention groups improved on two memory tests (p<.001 and p<.01). In the memory strategy training group, an increase in strategy use in daily life was the strongest predictor (p<.05) of improvement in subjective memory functioning.

Conclusions: Older adults with subjective memory complaints benefit from memory strategy training, especially in their memory functioning in daily life. (JINS, 2018, 24, 1110-1120).
