【摘要】 目的:构建主观认知下降老年人双重任务训练方案，为改善其认知功能的研究提供参考。方法:基于大脑可塑性理论、认知储备理论、认知-运动互增强理念，采用文献研究形成方案初稿，于2024年3月—5月通过德尔菲法进行2轮专家咨询修订方案。结果:最终纳入专家14名，2轮问卷有效回收率分别为100.0%、93.3%，专家权威系数为0.87。第2轮专家咨询的肯德尔和谐系数为0.295(P<0.001)，条目的变异系数为0～0.166。最终构建的方案主要内容包括主观认知下降知识教育、双重任务训练介绍、学习及熟悉训练动作、掌握及练习训练动作、维持训练效果。结论:主观认知下降老年人双重任务训练方案科学、可行，可为临床前期延缓认知下降的相关研究提供参考。更多还原

【Abstract】 Objective: To construct a dual-task training program for the elderly with subjective cognitive decline and to provide a reference for the research on improving their cognitive function. Methods: The intervention program was developed based on the brain plasticity theory, cognitive reserve theory, and cognition-exercise mutual enhancement concept. The first draft of intervention program was formed by literature research, and subsequently revised by two rounds of expert consultation from March to May 2024. Results: Totally 14 experts were included. The recovery rates of two rounds of questionnaire were 100.0% and 93.3%, respectively. The expert authority coefficient was 0.87. The Kendall harmony coefficient for the second round were 0.295(P<0.001), and the variation coefficients of each item ranged from 0 to 0.166. The main contents of the final constructed program include knowledge education on subjective cognitive decline, introduction to dual-task training, learning and familiarity with training movements, mastery and practice of training movements, and maintenance of training effects. Conclusion: The dual-task training program for the elderly with subjective cognitive decline is scientifically feasible and can provide a reference for related research on delaying cognitive decline in the preclinical stage.更多还原
