Abstract: Background　 Evidence-based medical evidence shows that there is no effective long-term treatment for mild cognitive impairment（MCI）.MCI patients can delay or prevent the progression of the disease through early cognitive intervention.However，the content of cognitive training at home and abroad is based on their respective research purposes and actual conditions.The program is currently in the stage of exploration and development，there is no uniform standard，and the evaluation of the intervention effect is therefore controversial.Objective　To construct a cognitive training system of MCI and provide a theoretical basis for the standardization of MCI cognitive interventions.We aim to build a system of MCI cognitive training suitable for China's national condition by further improving the application of cognitive intervention in patients with MCI in communities and providing support and reference for cognitive intervention training in China.Methods　From December 2015 to March 2017，based on the theory and literature research of brain plasticity，MCI cognitive training system was preliminarily constructed and further improved by two rounds of modified Delphi expert consultation method.Results　After two rounds of consultation，a MCI cognitive training system consisting of 8 first-level indicators，25 second-level indicators and 42 third-level indicators was formed.The active coefficients of experts in two rounds were 86.7% and 100.0%，respectively，the effective rates of the questionnaire were 92.3% and 100.0%，respectively.The judgment coefficient of experts in training system was 0.92，the degree of familiarity was 0.54 and the authority degree was 0.73.The coordination coefficients（W） of two rounds of expert consultation were 0.15 and 0.40，respectively，with statistical significance（P<0.05）．Conclusion　The MCI cognitive training system is preliminarily constructed by Delphi expert consultation method.The selected experts have a good representativeness，a high degree of authority，and the opinions of them are coordinated.From the methodology established by the indicator system，the results of this study are reasonable and reliable.

摘要： 背景　 循证医学证据显示轻度认知功能损害（MCI）目前尚无有效的长期治疗药物，通过早期认知干预可延缓或阻止MCI的病情发展。然而国内外的认知训练内容多是根据各自的研究目的和实际情况制定相应的干预方案，目前正处于探索及发展阶段，尚无统一标准，干预效果的评价也受到争议。目的　构建MCI认知训练内容体系，为MCI认知干预的标准化和规范化提供理论依据；通过在社区MCI人群的认知干预中应用并进一步完善该体系，编制出适合中国国情的MCI认知训练内容体系，为进一步开展认知干预提供支持。方法　2018年12月—2017年3月，在大脑可塑性理论和文献研究基础上，拟定MCI认知训练内容体系的初步框架，通过两轮改良的德尔菲专家咨询法对MCI认知训练内容体系框架进行论证和完善。结果　共纳入13名咨询专家，经过两轮咨询，最终形成了由8个一级指标、25个二级指标、42个三级指标构成的MCI认知训练内容体系。两轮咨询的专家积极系数分别为86.7%、100.0%，有效问卷回收率分别为92.3%、100.0%；专家对认知训练内容体系构建的判断依据系数为0.92、熟悉程度为0.54、权威程度为0.73；两轮专家咨询一级指标的协调系数（W）分别为0.15、0.40，有统计学意义（P<0.05）。结论　采用德尔菲专家咨询法初步构建了MCI认知训练内容体系；选取的专家具有较好的代表性，权威程度较高，专家意见协调一致，指标体系建立的方法学具有合理性、可靠性。
