越来越多的研究表明，在没有客观认知功能障碍或抑郁的情况下，老年人的主观认知下降(SCD)可能是非标准化认知下降的先兆，并最终发展为痴呆症。然而，人们对目前用于评估SCD的自我报告措施的关键特征知之甚少。主观认知衰退倡议(SCD-I)工作组是一个国际联盟，旨在制定SCD的概念框架和研究标准(Jessen等人，2014，阿尔茨海默病10,844-852)。在本研究中，我们系统地比较了代表8个国家和5种语言的19项SCD-I工作组研究使用的认知自我报告项目。我们确定了34个自我报告量表，包括640个认知自我报告项目。测量之间几乎没有重叠--大约75%的测量只被一项研究使用。在回答选项和项目内容方面存在很大差异。与记忆领域有关的项目最多，约占调查项目的60%，其次是执行功能和注意力，分别占16%和11%。与人名记忆和常见物品摆放有关的项目所占比例最大(各占56%)。工作组成员报告说，选择工具的决定往往基于特别是SCD研究之外的实际考虑，例如措施的可用性和简洁性。结果证明，对SCD的新兴结构的研究方法的异质性。我们为仪器选择和未来的研究方向提供了初步建议，包括确定与重要临床结果相关的项目和测量格式。
Research increasingly suggests that subjective cognitive decline (SCD) in older adults, in the absence of objective cognitive dysfunction or depression, may be a harbinger of non-normative cognitive decline and eventual progression to dementia. Little is known, however, about the key features of self-report measures currently used to assess SCD. The Subjective Cognitive Decline Initiative (SCD-I) Working Group is an international consortium established to develop a conceptual framework and research criteria for SCD (Jessen et al., 2014, Alzheimers Dement 10, 844–852). In the current study we systematically compared cognitive self-report items used by 19 SCD-I Working Group studies, representing 8 countries and 5 languages. We identified 34 self-report measures comprising 640 cognitive self-report items. There was little overlap among measures—approximately 75% of measures were used by only one study. Wide variation existed in response options and item content. Items pertaining to the memory domain predominated, accounting for about 60% of items surveyed, followed by executive function and attention, with 16% and 11% of the items, respectively. Items relating to memory for the names of people and the placement of common objects were represented on the greatest percentage of measures (56% each). Working group members reported that instrument selection decisions were often based on practical considerations beyond the study of SCD specifically, such as availability and brevity of measures. Results document the heterogeneity of approaches across studies to the emerging construct of SCD. We offer preliminary recommendations for instrument selection and future research directions including identifying items and measure formats associated with important clinical outcomes.
