We aimed to determine whether remote cognitive training (CT) is feasible and has the potential to improve cognitive function and work performance in Japanese workers.
From June to September 2020, this intervention time series study enrolled workers aged 18-65 years from 10 companies located in a metropolitan area of Japan. Cognitive function tests and self-administered questionnaires were completed by the participants three times: at baseline, after 12 weeks of CT, and after a further 12 weeks following cessation. We measured work performance with the question: "How would you rate your performance (compared with your optimum performance) over the past 4 weeks?" Responses were made via a visual analog scale (0-100). Cognitive function was assessed using the THINC-integrated tool, which is a brief, objective computerized cognitive assessment battery. For our computerized remote CT intervention, BrainHQ was used on the basis of our scientific rationale and the empirical literature. We recommended three 20-min sessions of BrainHQ per week and sent participants three reminders.
In total, 119 participants were recruited to this study. Only 22.7% of the subjects achieved the recommended training time of 720 min over 12 weeks. The median training time was used to divide participants into long and short- training groups. The long-training group showed a greater improvement in attention and executive function than the short-training group but there was no significant improvement in work performance after CT compared to baseline.
Our results suggest that although remote CT was not feasible enough, the effects on cognitive function can be expected by increasing training time and motivation.
我们旨在确定远程认知训练（CT）在日本员工中是否可行，以及是否有改善认知功能和工作表现的潜力。
2020年6月至9月，这项干预性时间序列研究招募了来自日本大都市地区10家公司的18 - 65岁员工。参与者在三个时间点完成认知功能测试和自我管理问卷：基线时、CT训练12周后以及停止训练再过12周后。我们通过询问“你如何评价你过去4周的工作表现（与你最佳表现相比）？”来衡量工作表现。通过视觉模拟量表（0 - 100）进行回答。使用THINC综合工具评估认知功能，这是一种简短、客观的计算机化认知评估组合。对于我们的计算机化远程CT干预，基于我们的科学原理和实证文献，使用了BrainHQ。我们建议每周进行三次每次20分钟的BrainHQ训练，并向参与者发送三次提醒。
本研究共招募了119名参与者。在12周内，只有22.7%的受试者达到了建议的720分钟训练时间。使用训练时间中位数将参与者分为长训练组和短训练组。长训练组在注意力和执行功能方面的改善比短训练组更大，但与基线相比，CT训练后工作表现没有显著改善。
我们的结果表明，虽然远程CT的可行性不足，但通过增加训练时间和积极性，可以预期其对认知功能的影响。
