The Impact of Memory-Strategy Training Interventions on Participant-Reported Outcomes in Healthy Older Adults: A Systematic Review an Meta-Analysis

A number of memory-strategy training interventions have been developed to target and reduce the impact of normal age-related memory decline. Most outcome studies to date have used objective memory measures to evaluate the efficacy of such interventions. Participant-reported outcomes, well-suited to capture the extent to which such interventions address the expressed concerns of aging persons, have been less closely examined. We conducted a systematic review and meta-analysis to examine whether memory-strategy training interventions improve participant-reported outcomes in healthy older adults with age-related memory changes. Of 536 identified articles, a total of 18 randomized controlled trials met the inclusion criteria for the review, and 15 of these provided relevant data to include in the meta-analyses. A systematic risk of bias assessment identified common problems with recruitment and masking procedures. Results from the meta-analyses indicate that memory interventions produce positive effects on several participant-reported outcomes, including improvements in perceived memory ability, memory self-efficacy, strategy use, memory-related affect, psychological well-being, and quality of life. Memory-strategy training interventions have a meaningful perceived impact on healthy older adults experiencing age-related memory changes. Future research utilizing stronger study designs (e.g., masking participants and study staff) and more closely investigating everyday functional impact is needed.
