the aim of this study was to investigate the effect of computer-assisted cognitive training in healthy older adults with subjective memory complaints.
Forty older adults, mean age (standard deviation) = 66.4 (5.6) with subjective memory complaints, were included in this study. Participants were randomly assigned to an integrated psychostimulation program (IPP) (N = 17), a computerized cognitive training (CCT) (N = 12) or a control group (N = 11). The training was applied for 8 weeks (90 min/d, 4 d/week for IPP, and 60 min/d, 4 d/week for CCT). Effectiveness was evaluated with a neuropsychological assessment battery, used before and after the implementation of the cognitive training.
According to the data analysis, with analysis of covariance (ANCOVA), we found a statistically significant change in the majority of the cognitive variables measured before and after the experimental conditions compared with the control group. Although, according to a paired t-test, the IPP was more effective in the improvement of cognitive functioning in the participants. Additionally, a decrease in anxiety symptoms was observed after the cognitive intervention in IPP and CCT conditions.
Our findings suggested that cognitive training of moderate intensity, supported by a web platform, could lead to significant improvements in cognitive and psychological well-being in older people with subjective memory complaints.
本研究旨在调查计算机辅助认知训练对有主观记忆抱怨的健康老年人的影响。
本研究纳入了40名有主观记忆抱怨的老年人，平均年龄（标准差）=66.4（5.6）岁。参与者被随机分配到综合心理刺激项目（IPP）组（N = 17）、计算机化认知训练（CCT）组（N = 12）或对照组（N = 11）。训练为期8周（IPP组每天90分钟，每周4天；CCT组每天60分钟，每周4天）。在认知训练实施前后使用神经心理评估量表评估训练效果。
根据数据分析，通过协方差分析（ANCOVA），我们发现与对照组相比，在实验条件前后测量的大多数认知变量有统计学上的显著变化。不过，根据配对t检验，IPP在改善参与者认知功能方面更有效。此外，在IPP和CCT条件下进行认知干预后，焦虑症状有所减轻。
我们的研究结果表明，由网络平台支持的中等强度认知训练可以显著改善有主观记忆抱怨的老年人的认知和心理健康。
