This study examined the combined effects of StrongerMemory program (brain exercises involving reading, writing, and math) and weekly social engagement on cognitive, behavioral, and emotional outcomes in older adults with subjective cognitive decline (SCD). A 12-week randomized controlled trial was conducted with 50 participants, who were randomly assigned to either a control group (StrongerMemory only) or an intervention group (StrongerMemory plus weekly social engagement). Cognitive function (MoCA), perceived cognitive decline (SCD-Q), health behaviors (GHPS), and emotional well-being (SWEMWBS) were assessed at baseline and post-intervention. Both groups showed significant cognitive improvements (increased MoCA, decreased SCD-Q) post-intervention. ANCOVA revealed significantly better cognitive function in the intervention group, demonstrating the synergistic benefits of social engagement. The intervention group also experienced enhanced emotional well-being. These findings suggest that incorporating social engagement into cognitive training programs enhances their effectiveness in improving cognitive function and emotional well-being in older adults with SCD, potentially mitigating further decline. While the findings are promising, this exploratory study's small sample size resulted in modest achieved power (0.64), which may limit the generalizability of the results.
本研究考察了“增强记忆”项目（包括阅读、写作和数学的脑部锻炼）与每周社交活动相结合对主观认知衰退（SCD）的老年人认知、行为和情绪结果的综合影响。对50名参与者进行了一项为期12周的随机对照试验，这些参与者被随机分配到对照组（仅进行“增强记忆”项目）或干预组（“增强记忆”项目加每周社交活动）。在基线和干预后评估认知功能（蒙特利尔认知评估量表）、感知认知衰退（SCD问卷）、健康行为（综合健康促进量表）和情绪幸福感（ Warwick-Edinburgh心理健康量表）。两组在干预后均显示出显著的认知改善（蒙特利尔认知评估量表得分增加，SCD问卷得分降低）。协方差分析显示干预组的认知功能明显更好，表明社交活动具有协同益处。干预组的情绪幸福感也有所增强。这些发现表明，将社交活动纳入认知训练项目可提高其对改善SCD老年人认知功能和情绪幸福感的有效性，可能减轻进一步衰退。虽然这些发现很有前景，但这项探索性研究的样本量较小，导致实际效能适中（0.64），这可能会限制结果的普遍性。
