We explored whether newly developed application (Smartphone-based brain Anti-aging and memory Reinforcement Training, SMART) improved memory performance in older adults with subjective memory complaints (SMC).
A total of 53 adults (range: 50-68 years; 52.8% female) were randomized into either one of two intervention groups [SMART (n = 18) vs. Fit Brains® (n = 19)] or a wait-list group (n = 16). Participants in the intervention groups underwent 15-20 minutes of training per day, five days per week for 8 weeks. We used objective cognitive measures to evaluate changes with respect to four domains: attention, memory, working memory (WM), and response inhibition. In addition, we included self-report questionnaires to assess levels of SMC, depression, and anxiety.
Total WM quotient [t(17) = 6.27, p < .001] as well as auditory-verbal WM score [t(17) = 4.45, p < .001] increased significantly in the SMART group but not in the control groups. Self-reports of memory contentment, however, increased in the Fit Brains® group only [t(18) = 2.12, p < .05).
Use of an 8-week smartphone-based memory training program may improve WM function in older adults. However, objective improvement in performance does not necessarily lead to decreased SMC.
我们探讨了新开发的应用程序（基于智能手机的大脑抗衰老和记忆强化训练，SMART）是否能改善有主观记忆抱怨（SMC）的老年人的记忆表现。
共有 53 名成年人（年龄范围：50-68 岁；52.8%为女性）被随机分为两个干预组之一[SMART（n=18）与 Fit Brains®（n=19）]或等待名单组（n=16）。干预组的参与者每天接受 15-20 分钟的训练，每周 5 天，共 8 周。我们使用客观认知测量来评估四个领域的变化：注意力、记忆、工作记忆（WM）和反应抑制。此外，我们还包括自我报告问卷来评估 SMC、抑郁和焦虑的水平。
SMART 组的总 WM 商数[t(17)=6.27，p<.001]以及听觉言语 WM 分数[t(17)=4.45，p<.001]显著增加，但对照组没有。然而，记忆内容满意度的自我报告仅在 Fit Brains®组中增加[t(18)=2.12，p<.05]。
使用 8 周基于智能手机的记忆训练计划可能会改善老年人的 WM 功能。然而，表现的客观改善不一定会导致 SMC 减少。
