Scientific investigations have highlighted the benefits of cognitive stimulation for cognitive, psychological, and social aspects in older individuals. However, there is a dearth of long-term, methodologically-rigorous studies. The aim of the present study was to describe the methods and the initial characteristics of the participants in a randomized controlled trial on cognitive stimulation. A total of 578 older individuals accepted invitations to participate in the study. Of these respondents, 362 met the eligibility criteria, and 255 were selected and randomized into the training, active control, and passive control groups. During the baseline stage (T0), 48 participants withdrew, resulting in a final T0 sample of 207 participants. The three groups were similar in terms of cognitive performance and sociodemographic and psychosocial variables, but they differed significantly regarding depressive symptoms, with the training group scoring higher. The methods herein described can help guide future research on cognitive stimulation in older adults.
科学调查凸显了认知刺激对老年人认知、心理和社会方面的益处。然而，缺乏长期的、方法严谨的研究。本研究的目的是描述一项关于认知刺激的随机对照试验的方法及参与者的初始特征。共有578名老年人接受邀请参与该研究。在这些受访者中，362人符合入选标准，255人被选中并随机分为训练组、积极对照组和消极对照组。在基线阶段（T0），48名参与者退出，最终T0样本为207名参与者。三组在认知表现、社会人口统计学和心理社会变量方面相似，但在抑郁症状方面差异显著，训练组得分更高。本文所述方法有助于指导未来关于老年人认知刺激的研究。
