comparing CCT,MET,LKM elderly, executive functions

Declines in cognitive abilities are a common feature of aging and are associated with decreases in quality of life, dependence, and increases in mortality rate. In a randomized clinical trial with parallel design performed in Tehran, 100 elderlies aged 65-75 were randomly assigned to computerized cognitive training group, loving-kindness meditation group, multiple exemplar training group, and control group. All the participants underwent assessments at baseline, after intervention and six-month follow-up. Addenbrooke's Cognitive Examination test, and executive functions test were administered. Then, an eight-week (16 sessions) intervention was performed in each experimental group. The results of this study showed that all three interventions of cognitive training, multi exemplar training, and loving-kindness meditation had significant effects on executive functions. However, each of them had different effects on the different variables of these functions and their effect size varies. In the psychological well-being variable, the love-kindness meditation intervention was the most effective intervention and cognitive training did not show a significant effect on this variable. Based on the results, it can be concluded that loving-kindness meditation and multiple exemplar training have a significant effect on psychological well-being and executive functions of elderlies and it is expected to have a positive effect on the quality of life of the elderlies. It is suggested that training the elderly with these interventions can have a positive impact on the elderly’s life and should be incorporated into their daily lives abbreviation of variables: Tower Of Hanoi Task (TOH),Trail Making Task (TMT),Symbol Digit Modality Task (SDMT),The Color and Word Stroop Task (Stroop),Backward Digit Span Task (BDST). the data should open with SPSS program.认知能力下降是衰老的常见表现，与生活质量降低、自理依赖程度提升及死亡率升高密切相关。本研究在德黑兰开展一项平行设计随机对照试验，共纳入100名年龄65至75岁的老年人，将其随机分配至计算机化认知训练组、慈爱冥想（loving-kindness meditation）组、多范例训练组及对照组。所有受试者均在基线、干预后及6个月随访阶段接受评估，测试工具包括阿登布鲁克认知检查测验（Addenbrooke's Cognitive Examination）与执行功能测试。随后，各实验组均完成了为期8周（共16课时）的干预方案。 研究结果显示，计算机化认知训练、多范例训练与慈爱冥想三种干预方式均对执行功能产生了显著影响，但三者对执行功能的不同维度的作用效果存在差异，且效应量各不相同。其中在心理幸福感维度上，慈爱冥想干预的效果最为突出，而计算机化认知训练未对该维度产生显著作用。 基于上述结果可得出结论：慈爱冥想与多范例训练可显著改善老年人的心理幸福感与执行功能，有望对老年人的生活质量产生积极影响。建议将上述干预方式应用于老年群体，以发挥积极作用，并可将其融入老年人的日常生活。 本研究涉及的变量缩写如下：汉诺塔任务（Tower Of Hanoi Task, TOH）、连线测验（Trail Making Task, TMT）、符号数字模态测验（Symbol Digit Modality Task, SDMT）、色词斯特鲁普测验（The Color and Word Stroop Task, Stroop）、倒数字广度任务（Backward Digit Span Task, BDST）。本数据集可通过SPSS软件打开。
