综合认知训练对社区健康老人推理能力影响的对照研究

目的 探索综合认知训练对社区健康老人逻辑推理能力的中短期影响效果.方法 对上海市某街道社区老人(年龄≥70岁)以每50人一组筛查,共有151例老人符合入组标准并同意参加研究,按先后次序分为认知训练干预组(90例)和非认知训练组(对照组,61例).对干预组进行12周(共24次)的综合认知训练(包括推理训练、记忆训练等).分别于基线、干预结束时、干预后6个月、干预后1年采用中国老年成套神经心理测验(NTBE)对两组进行测查及推理训练前后进行课上瑞文推理测验测评.结果 干预组干预阶段推理训练后瑞文推理测验成绩高于训练前,差异具有显著性[( 15.54 ±5.70)分,(10.35±5.10)分,t=-10.595,P＜0.01].干预组NTBE推理测验3次随访均优于基线且优于对照组,差异具有显著性(P＜ 0.05或0.01).结论 综合认知训练对社区健康老人推理能力有提高作用且能持续1年有效性.

Effects of compositive cognitive training for healthy community elders in reasoning ability: a controlled trial

Objective To evaluate the effects of compositive cognitive training on reasoning ability for healthy community elderly.Method All the participants were selected from one district in Shanghai by every 50 samples.151 community healthy elderly who accorded with the standard were collected at last.They were divided into cognitive intervention group ( n =90) and control group ( n =61 ) by sequence.The interventions ( includes reasoning,memory training,et al) were conducted in 24 sessions over 12 weeks.All individuals were assessed by Neuropsychological Test Battery for Elderly (NTBE) at baseline,follow-up,half a year follow-up and one year follow-up phase,and Raven' s Standard Progressive Matrices on reasoning classes.Results The scores of Raven' s Standard Progressive Matrices were significantly higher after reasoning training in intervention group( (15.54 ±5.70),(10.35 ± 5.10),t =3.595,P ＜ 0.01 ).Compared with baseline,the reasoning test scores of NTBE were significantly higher after cognitive intervention in treatment group at follow-up phase,and were also significantly higher than control group (P ＜ 0.05 or P ＜ 0.01 ).Conclusion Results support the effectiveness of compositive cognitive training in improving reasoning ability are positive,and can last for one year.
